- This invention relates to improvements in tools for compressing sleeves of malleable metal upon wires for the purpose of making strong and durable joints between them.
An object of the invention is to provide a novel and advantageous combination of forming and compressing dies, levers, and hand operated parts, whereby high degrees of compressing forces may be applied to sleeves to compress them upon wires.
Another object of the invention is to provide a novel combination and arrangement of adjustable parts whereby two die blocks having two spacedpairs of oppositely disposed compressing grooves may be adjusted to bring either pair into operative relation to the force applying levers of the tool.
Another object is to provide a novel construction of work-engaging stop parts in novel relation to-the compressing dies, whereby the dies and the sleeves to be compressed thereby may be set in proper relative positions for a compressing operation upon a sleeve or for a plurality of compressing operations at different places upon a sleeve.
Figure 3 is' a side view of the upper: portion of the tool.
Figure 4 is a sectional detaihjhowing the die blocks, the lever members carrying the same and one of the links on which the members are pivoted. Q
Figure 5 is a sectional detail, on line 5-5 of Fig. 1, showing the dies and the work-engaging stop parts and a sleeve and wires thereinwith the sleeve in position to have a part thereof acted upon by the dies. Q
Figure 6 is'a view similar to Fig. 5, showing the tool moved to another position relatively to the sleeve to have another part of the sleeve acted upon by the dies. I
Figure 7 is a view similar to Fig. 5, showing the parts of the tool in a reversed position with relation to the sleeve and wires and showing .in Fig. 2. and sothat when the arms 2, 2 are 55 the sleeve in a position to have a third part thereof acted upon by the dies.
Figure 8 is a view similar to Fig. 7, showing the tool moved to another position relatively to the sleeve to have. a fourth part thereof acted upon by the dies.
Referring to the drawings 2, 2 designate two lever arms having their upper ends pivoted together, at 3, centrally of the tool and having their lower ends provided with handles 4, 4 by means of which the arms may be moved from and toward each other.
The upper end portions of the lever arms 2, 2 are provided with adjusting sections 5, 5 whose lower end portions are pivoted thereto, at 6, 6. The upper end portions of the sections are pivoted, at'l, 1, to the lower ends of two lever members 8, 8, and the sections 5, 5 are locked in fixed positions relatively to the lever arms 2, 2 by set screws 9, 9 which are screwed into and through lugs l0, l on the arms 2, 2 and engage lugs I I, II on the'sections 5, 5, and by set screws l2, l2 which are screwed into and through parts [3, ll of the sections 5, and engage parts M, H of the arms 2, 2.
By loosening the set screws I2, l2 and turning the set screws 9, 9 forwardly the pivoted upper ends of the sections 5, may be adjusted toward the pivot 3 of the arms 2, 2, and by loosening the set screws 9, 9 and turning the set screws l2, l2 forwardly the pivotedupper ends of the sections 5, 5 may be adjusted away from the pivot 8 of the arms 2, 2; otherwise the sections 5, 5 form, in'
effect, integral parts of the arms 2, 2, the arms 2, 2, and sections 5, 5 constituting toggle levers.
The lever members 8, 8 are located between two links 15 and IS on which the members are fulcrumed by means of bolts l1, II. The links I! and it are spaced above thelarms 2, 2 and their adjusting sections 5, i, and the members 8, 8
have free end portions l8, l8 which extend above the links I! and It.
The pivots I, 'I'of the sections 5, 5 of the arms 2, 2, and the fulcrum bolts l1, ll of the lever members 8, 8 are related to each other and to the pivot 3 of the arms 2, 2 so that, when the arms are moved apart or from each other, the pivots I, 1 will be moved toward eachother above the pivot 3 and thereby move the lower ends of the lever members 8, 8 toward each other and the upper freeend portions l8, l8 of the members away from each other to move the parts of the tool to the open position, as shown thereafter moved toward each other, the pivots I, 1 will be moved away from each other and thereby move the lower ends of the lever members 8, 8, away from each other and the upper free end portions I8, I8 of the members toward each other to move the parts of the tool to the closed position, as shown in Fig. 1. The arms 2, 2 are provided with suitable stop parts I9, I9 to limit the extent of movement of the arms 2, 2 when they are moved toward each other.
The lever members 8, 8 are provided with coacting gear teeth 28, 28, see Fig. 4, between their fulcrum bolts I1, I1 which serve to preserve equal movements of the lever members 8, 8 on their fulcrum bolts when the parts of the tool are moved from one to the other of their closed and open positions.
The lever members 8, 8 carry two die blocks 2|, 2| which are seated against the inner, opposing surfaces of the free end, portions I8, I8 thereof. The die blocks 2|, 2| are carried by the inner ends of pivot pins 22, 22 which are fitted to turn and to slide longitudinally in the end portions I8, I8 of the members 8, 8, and which are in axial aiinement, or substantially so, when the parts of the tool are in theclosed position shown in Figs. 1 and 4.
The die blocks 2 I, 2| are constructed to extend normally to the axes of their pivot pins 22, 22 and to be in parallel relation, or substantially so, when the parts of the tool are in the closed position, and they are provided with two spaced pairs of. oppositely disposed compressing grooves 23, 23 and 24, 24 which are located above and below or on opposite sides of, their pivot pins 22, 22.
The die blocks 2|, 2| are adjustable on their pivot pins 22, 22 to bring either pair of their compressing grooves 23, 23 or 24, 24 into the operative position which is near the fulcrums of the members 8, 8 and between the links I5 and I6 and the pivot pins 22, 22.
The outer end portions of the pivot pins 22, 22 are surrounded by helical springs 25, 25 which are housed within openings 28, 28 in the end portions I8, I8 of the members 8, 8. These springs 25, 25 bear against the inner end walls of the openings 28, 28 and against heads 21, 21
. on the outer ends of the pins 22, 22 and urge the pins outwardly and hold the die blocks 2|, 2| in firm engagement with the opposing inner surfaces of the member end portions I8, I8. When the die blocks 2|, 2| are thus held by the springs, transverse grooves 28, '28 in the outer walls of the blocks embrace and engage corresponding projecting ribs 29, 29 on the member end portions I8, I8, and thereby lock the blocks in normal position with respect to the said end portions by preventing the blocks from being turned about the axes of their pivot pins.
When it is desired to reverse the ends of the die blocks 2|, 2| to bring either pair of grooves 23, 23 or 24, 24 into the operative position in close relation to the fulcrums of the members 8, 8, the pins 22, 22 and blocks 2|, 2| are pressed inwardly against the action of the springs 25, 25 until the walls 'oi the grooves 28, 28 clear the ribs 29, 29, whereupon the blocks may-be turned on ,their pivot pins to effect the adjustment desired. After the adjustment has been effected, the walls of the grooves 28, 28 re-engage the ribs 29, 29 to lock the blocks in place.
Each pair of compressing grooves 23, 23 and 24, 24 is provided to receive and compress a sleeve when the pair is in the operative position, and the grooves of the pair 24, 24 are larger than grooves of the pair 23, 23 to act upon a larger sleeve than that acted upon by the pair 23, 23, and thus it will be understood that by adjusting the die blocks 2|, 2 I, as previously explained, the tool may be used to compress sleeves of at least two different sizes.
In Figs. 4 to 8, inclusive, there are illustrated the meeting end portions of two wires 38, 30 inserted into the respective end portions of a connecting sleeve 3|, and there are illustrated therein different positions of parts of the tool relatively to the wires and the sleeve during several operations of the tool in compressing the sleeve upon the wires, as will be hereinafter explained.
The links I5 and I8 carry two parallel, workengaging stop plates 32 and 33, respectively, located on the respective sides of the die blocks 2|, 2| in spaced relation thereto, the plate 33 being spaced farther from the die blocks than the plate 32, as clearly shown in Figs. 5, 6, '7, and 8. The plate 32 is secured to the link l5 by means of a screw 34, and the plate 33 is provided with a flange 35 which is seated in a groove 38 in a bracket 31 which is secured to the link I8 by a screw 38. The flange 35 1s adjustable in the groove 38 to move the plate 33 closer to or farther from the die blocks 2|, 2|, and the flange 35 and plate 33 are secured to the bracket 31 in different positions of. adjustment thereon by means of a screw 39 whichextends through a slot 40 in the bracket 31 and is screwed into the flange 35.
The stop plates 32 and 33 are arranged to receive the sleeve 3| between them, and they are provided with slots 4| and 42, respectively, which receive the wires 30, 30 when the sleeve 3| is placed between the plates.
When the die blocks 2 I 2| are adjusted to have their compressing grooves 23, 23 in the operative position, a pin 43 receives the sleeve 3| .and forms a. stop to properly position it between the grooves 23, 23 to be acted upon thereby; and when tlrie 'die blocks are adjusted to have their larger compressing grooves 24, 24 in the operative position, the, bottom walls of the slots 4| and" receive the wires projecting from the sleeve to be acted upon and form stops toproperly position the sleeve between the grooves 24, 24. When the compression grooves 24, 24 are in the operative position the lever arms 2, 2 are moved apart to a position in which the space between the upper or outer longitudinal edges of the grooves 24, 24 is equal to or slightly in excess of the diameter of the sleeve to be compressed between the grooves 24, 24, the lower or inner longitudinal edges thereof are close enough to form stops which are contacted by the sleeve to properly position it between the grooves if any irregularities in the .wires projecting from the sleeve prevent the proper positioning of the sleeve by the engagement of the wires with the bottom walls of the slots 4| and 42.
The parts of the tool, as herein illustrated, are constructed and arranged to compress a sleeve on the meeting end portions of two wires in four compressingoperations of the tool, two of such operations compressing one end portion of the sleeve upon one of the wires, and the remaining two of such operations compressing the other end portion of the sleeve upon the other of the erations, the die blocks 2|, 2| being adjusted to set the compression grooves 23, 23 in the operative position. r
-The end portions of the wires 30, 30 are first inserted into the respective end portions of the sleeve 3| and the end portions of the sleeve are indented by the aid of suitable hand pliers to cause sufiicient binding action between the wire end portions and the sleeve to hold them in assembled condition for the compressing actions of the tool.
The lever arms 2, 2 of the tool are then moved' apart to set the tool in the open position and the tool is then moved relatively to the wires 30, 30 and sleeve 3| to bring the wires 30, 30 into the slots 4i and i2 and to bring the sleeve 3| to a position between the grooves 23, 23 of the die, blocks 2|, 2|, and between the stop plates 32 and each other to move the parts of the tool to the closed position shown in Fig. 1. As the parts of the tool are thus moved to the closed position, the pivots l, i of the lower ends of the lever members 8, 8 are moved outwardly and downwardly to positions on opposite sides of the pivot 3 of the arms 2, 2, in toggle-like action, to move the upper free end portions l8, ill of the lever arms 8, 8 and the die blocks 2|, 2| carried thereby to the closed position with great force. blocks are thus closed, the walls of the grooves 23, 23 thereof are moved toward each other and toward the space betweenthe axes of the fulcrurn bolts l1, l! by a toggle-like'action of the free end portions of the lever members 8, 8, so that the walls of the grooves receive and act upon the sleeve to compress the same upon the wire therein with a high degree of force, for the production of the firstcompressed portion 44 of the sleeve. During the compression of the sleeve by the die blocks, some of the metal of the part being compressed flows outwardly into the space between the die blocks 2|, 2|, outwardly of the grooves 23, 23, and some of the metal flows lengthwise of'the sleeve and elongates' it slightly.
After the portion 44 of the sleeve 3| has been compressed,.as just described, the, tool is opened and moved longitudinally of the wires 30, 30 to bring the stop plate 33 into position in contact with the adjacent end of the sleeve 3|,-as shown in Fig. 6, whereupon the tool is closed for a second compressing operation upon the sleeve, for the production of the second compressed portion 45 of the sleeve. After the two'compressed portions 44 and 45 have been produced, the tool is opened and withdrawn or removed from the wires 30, 30 and sleeve 3|, and the tool is turned or reversed to bring its stop plates 32 and 22 into reversed positions with respect to the ends of the sleeve, as shown in Figs. 7 and 8. Following this reversal of the positions of the stop plates, the tool is reapplied to the wires and sleeve with the wires in the slots of the stop plates and the sleeve between the grooves 23, 23 of the die blocks and between the stop plates and with one endof the sleeve in contact with the, stop plate 32, as shown in Fig. 7, whereupon the tool is again closed for a third compressing operation upon the sleeve for the production of the third compressed portion 45 of the sleeve.
After the portion 46 of the sleeve has been compressed, as just-described, the tool is again opened and moved longitudinally of the wires to bring As the die.
v 3 the stop plate 33 into position in contact with the adjacent end of the sleeve 3|, as shown in Fig. 8, whereupon the tool is closed for a fourth compressing operation for the production of thefourth compressed portion 41 of the sleeve. The tool is then opened and withdrawn or removed from the wires and the sleeve, leaving the sleeve compressed or swaged upon the wires at the four places, 45, 46 and 41.
As the die blocks 2|, 2| are moved toward each other on arcuate lines struck from the fulcrums l1, I! of the lever members 8, 3, during the compressing operations, there is a tendency for more metal of the sleeve being compressed to flow outwardly from the compressing grooves 23, 23 and the adjacent spaces between the die blocks 2|, 2| farthest from the fulcrums I, I, and, therefore, such adjacent space'is provided with oilset portions having walls which diverge outwardly from the adjacent walls of the grooves 23, 23, as clearly shown in Fig. 4,.and thus provide additional space for the reception of themetal forced from within the confines of the grooves 23, 23.
