Definitions

  • the present invention is an improvement on United States Patent No. 1,300,140. issued to me on the 8th day of April, 1919, formattress roll forming machine, reference to which patent is hereby made, 1n order that the present lmprovement may be fully comprehended.
  • a mattress supporting table' supports a mattress having the usual rounded corners, 'to be worked by a mattress roll forming and stitching machine slidably. mounted to move around the sides and ends I of the table to form a roll on the edge of said mattress, said machine being moved. predetermined distances-at regular intervals to operate on the mattress.
  • the primary object of the present invention is to provide improved means for automatically reducing the speed of the operating machine while rounding the corners and for automatically increasing the speed to normal as soon as the rounded corner has been passed.
  • Figure 1 is a broken elevation of one corner of the supporting table disclosing the mattress roll forming and stitching machine slidably mounted upon one side thereof and approaching said corner;
  • Fig. 2 is a broken right hand elevation .of'
  • Fig. 3 is a left hand elevation of Fig. 1 disclosing the variable speed mechanism and its controlling device;
  • Figs't and 5 are enlarged broken detailed views disclosing a portion of the variable speed mechanism in different positions as' viewed from the line 45 in Fig. 3 of the "drawings and in the direction indicated;
  • Fig. is an enlarged broken detailed view, partly in section, disclosing the low speed members
  • FIG.7 is a sectional view taken on line 7-7 of Fig. 6; inthe direction indicated, and
  • Fig. 8 is a broken plan View of the table disclosing the positions of the trips for automatically shifting the variable speed mechanism.
  • the numeral 1 is used to designate a mattress supporting table having a top 2 with. rounded corners 3' thereon and a vertically disposed flange .4 arranged on all sides of said top 2.
  • the roll forming and stitchingmachine comprises, briefly, a frame carrying a suita mattress roll Y packing and sewing mechanism 21 as well as the moving means 26 or moving the machine relatively to the ta le 1 and the mattress thereon, not shown.
  • the countershaft 17 is'also provided with a second gear 27 which meshes with a gear 28 rotatably mounted upon the shaft 23 and provided with a ratchet mechanism 29 arranged to engage a collar 31 on the shaft 23 and rotate said shaft when said ratchet mechanism travels at a greater speed-than said shaft, and to release said shaft when the same rotates at a greater speed than the mechahism 29, the purpose of which will hereinafter be more fully described.
  • the clutch member 22 feathered upon the main driving shaft 23 is provided with a grooved collar 32 which is engaged by the free end of a upon the rear of the machine 10 as at'34rand provided with a depending portion 36 arranged to be engaged by trips 37 stationed one at each corner of the table 1.
  • Figs. 6 and 7 disclose portions .of the variable speed transmission, the views being arranged to conters Patent isz' 1.
  • a low speed gear rotatably mounted upon the driving shaft in meshing relation with the low speed gear of the counter shaft; and means for automatically impartingrotation through said low speed gears to the driving,
  • variable speed mechanism comprising a main driving shaft: a power driven counter shaft: normal and low speed gears mounted upon said counter shaft: a normal speed transmitting l gear mounted upon the driving shaftin meshing relation with the normal speed gear of the counter shaft: clutching means mounted upon the driving shaft adjacent the normal speed gear adapted tonormally impart rotation from said normal speed gear to said driving shaft: means for operating saidclutching means to release the driving shaft from said normal speed gear while traversing the rounded table corners; a low speed gear rotatably mounted upon the driving shaft in meshing relation with the low speed gear of the counter shaft; a ratchet operativel mounted adjacent said low speed gear on the driving shaft for automatically engaging said driving shaft and imparting rotation thereto when the speed of said driving shaft shall have been reduced to the speed of said low speed gear when the driving shaft is released from the normal speed gear.
  • said machine having operating and moving mechanism. of a variable speed mechanism mountedupon the machine to transmit movement to said operating and moving mechanism.
  • variable speed mechanism comprising a main driving shaft: a power driven counter shaft: normal and low speed gears mounted upon said counter shaft: a normal speed transmitting gear mounted upon the driving shaft in meshing relation with the normal speed gear of the counter shaft: clutching means mounted upon the driving shaft adjacent the normal speed gear adapted to normall impart rotation from said normal speed gear to said driving shaft; means for operating said clutching means to release the driving shaft from said normal speed gear while traversing the rounded table corners; a low speed gear rotatably mounted upon the driving shaft in meshing relation with the low speed gear of the counter shaft; a ratchetoperatively connecting said low speed gear to the driving shaft for automaticall engaging said shaft and imparting rotation thereto while released from engagement with the normal speed gear in traversing corners. and for permitting rotation of the driving shaft at normal speed when the nor-- mal speed clutch is in engagement.
  • variable speed mechanism comprising a main driving shaft: a power driven counter shaft: normal and low speed gears mounted upon said counter shaft: a normal speed transmitting gear mounted upon the driving shaft in meshing relation with the normal speed gear of the counter shaft: a clutch ope 'ativel v mounted upon the driving shaft adjacent the normal speed gear adapted to normally impart rotation from said normal speed gear to said driving shaft: a trip mounted at each corner of the table and arranged to operate the clutch to release the driving shaftfrom the normal speed gear while traversing the rounded table corners: a low speed gear rotatablv mounted upon the driving shaft in meshing relation with the low speed gear of 4 the counter shaft: a ratchetoperatlvely connecting said low speed gear to the driving shaft for automatically engaging said shaft and imparting rotation thereto while released from engagement with the normal speed gear in traversing corners. and for permitting rotation of the driving shaft at normal speed-when the normal speed clutch is in engagement.
