Claims. (01. 144-281) a hose actuated press, principal object a means by uniformly distributed over the platens carried and exercised by in the press a pair of platens horizontally disposed and vertically aligned with respect to their peripheral edges, and between which glue jointed work is placed to be pressed and heated when the power is applied to the press through the medium of fire hose sections distributed beneath the lower platen, the fire hose seating on a support adjustably arranged in the construction of the press, and means to inflate all of the fire hose sections simultaneously, hydraulically or pneumatically.

' A still further object of this invention is to provide a channel for each hose to maintain straight alignment thereof, and an equal dis,-

tribution of pressure across the platens, and

furthermore each channel may be of suflicient depth to stack a plurality b1 hose therein; in will be divided by a plate to float with the vertical movement of the hose and to avoid side displacement of the hose from vertical alignment with each other.

A further object of our invention is to provide a gauge to automatically control a predetermined pressure between said platens.

A still further object of our invention is to provide an'eflicient heating means for the press platens, said means to be optionally. exercised with respect to heating the platens. 7

A further object of our invention is to provide a simple and eflicient press whereby, gluing together the components of wood structures is easily and quickly'accomplished with respect to setting the glue rapidly and forcing the Joints to snug engagement. I

These and; other objects will hereinafter be required for the work carried 'Fig. 5 is an enlarged cross section of the hose,

its channel and hose pipe connection.

Slidably mounted on the (former posts' is ansaid frame beingdrilled at its corners to slidably engage on the said'comer posts whereby a bed is formed for vertical a ustment to carry the load of compression when the press is energizeg, the last said frafne to be secured a predetermined spaced distance from the lower frame by suitable blocking 5 and 6 as shown, or

' otherwise, spaced along the sides and ends of more fully explained, reference being had to press, partly Fig. 4 is enlarged side view of the hose and its channel, parts removed for convenience of illustration.v

the said beam elements. Upon said adjustable frame ismounted a floating. frame, said frame comprising a, plate 1 seating on the upper side of said adjustable frame, the comers of said plate being drilled in like manner to engage on the corner posts whereby a continuous bearing is provided across the, adjustable frame, and upon whichv lengths of L-shaped members I are placed in juxtaposition to form a plurality of channels extending from end to end of the press frame and of sufficient number to fill the space-from side to side of the press substantially as shown in Fig. 3.

Seating in each channel is a length or fire hose 4 9, the terminating ends of. which extend outward a short distance from their respective channels as shown in Fig. 4, said terminal ends being collapsed and clamped together simultaneously by a pair of bars Ill transversely to the fire hose v thereto by a coupling IS, the flexible hose being means to permit vertical movement of the movable frame, said flexible hose extending to and beingconnected to a source of supply later described. The said pipe l2 has a plurality of' laterals-16 extending therefrom to communicate with the corresponding-ends of the hose, as

shown in Figs. 2 and 4, the laterals each having aunion H whereby a defective hose length may be removed for repairs or'replacement by a new length of hose. The connection of the hose from the union upward is through the medium of a nipple I8, the upper endof which is provided with an annular flange C to bind the hose seating on an annular washer IS, the latter having an abrupt upper extension D to embed in the hose 1 to avoid expansion from its aperture through which the nipple extends, said washer seating on the said leg of the said, l -shaped member 8 that rests on the plate. I, said leg, plate, and leg of the I-beam 4 being drilled in registry and through whichjhe nipple extends and being tensioned by a nut 20 threadedly engaging thereon to secure the nipple air and liquid tight where it engages with the hose. It will now be seen how the hose lengths are removably conn d to'the press and communicating with the so cc of supply, pneumatically or hydraulically.

Each flre hose has a plate 2| positioned thereon to slidably engage vertically in the'channel thus provided, and each plate hasa channel 22 lying thereon with its legs upwardly extending,

and on which is secured a metallic sheet 28 tov cover the area between the corner posts. It will be seen that the legs of the channels thus formed will function as astqp to carry the load of the sheet 23, and a platen later described when the hose sections are collapsed by disengaging the pressure; furthermore there is provided short lengths of pipes 8 vertically secured to plate I to coact with the channellegs to carry the weight of said sheet and platen when released by collapsing the hose.

posts, whereby lateral movementbf said plate is obviated and adapted .to carry a hollow platen 24 seated thereon, said platen being in vertical registry with another platen 25 that is secured to the upper frame, the platens being secured to their respectivecarrying members by an L- shaped member 26 positioned at each end of each platen through" the medium of bolts 26' whereby the platens are likewise secured against lateral inovement when functioning as compressing elements, both of said platens being insulated from the elements'of the press byan asbestos sheet 21 to avoid free transmission or heat to the hose whereby excess expansion of air compressed will 1 be eliminated when the platens are heated.

The plates above referred to are the elements between which glue joined work 28 is placed,

Each corner of said sheet is drilled to likewise slidably engage on said corner similar to that shown in Fig. 3, said work being pressed for tight engagement of the glued joints as well as being heated by the platens ;for quick setting and hardening of the glue, the

platens being heated by steam injected therein through a supply pipe ill]. There is also provided an exhaust through pipe 3| whereby the steam is free to circulate through the platens. Inasmuch as platen 24 is arranged to move vertically for clamping purpose there is provided a flexible pipe 32 for the supply and the exhaust, while the upper platen 25 being stationarily secured to the top frame has a-rigid pipe connection 33.

Positioned in working relationto the flre hose 5 sections is a compression tank 34 vertically disposed, said tank having a supply pipe 35 communicatlng therewith at its upper end, the pipe connecting the tank with a source of supply and having a valve 36 therein as controlling means for the supply. There is also provided a supply pipe 31 for the fire hose, said supply extending upward from the tank and communicating with a pressure regulator 38, the pressure flow being controlled by a T-element 29 as adjusting means for the pressure, said pressure being recorded by .a gauge 40 to certain pressure imposed in the 'flre hose. T re is also provided a three-way valve 4| to make and break the flow leading to the fire hose and also as an exhaust for the hose through pipe 42.

The flre hose sections may be stacked plurally similar to that shown in Fig. 6, the hose sections being separated by a plate 2| heretofore described, the purpose of which is for the advantage of a greater vertical movement of the lower platen whereby the space between the stationary platen and the movable'platen may be increased for the convenience of installing work between said platens that may vary in height 40 without change of the blocking 5 and- B to vary the space between the platens.

The, press actuated by the fire may vary in' size and construction to accommodate for special kind of workyfor'example,

we have illustrated modiflcations'in Figs. '7 to 11 inclusive.

The structure of'Figs. 7 and 8 consistsof a pair of I-beams spaced apart in parallelism torunction as abase for the press, said I-lbeams' being secured in spaced relation at their lower extremity by a plate 44'-a djac ent each end of the be while the u r extremity thereof is secu ed together by a plate 45 extending longitudinally of the beams terminating a spaced distance inward from each end thereof The said I-beamseach are bored through their upper legs a spaced distance inward from their outer ends to receive corner posts 46 insertible therein, and secured by welding, each post being shouldered 0 a spaced distance upward by reducing the same 1 in diameter as shown in Fig. '7, and upon which understood that the upper and lower legs of said beams are bored in vertical registry for the corner posts and sli-dalble thereon but removably se curedby nut 48 threadedly enga ing on their respective posts that extends through the upper leg of the I-beam, each side of thelast said I-beam being enclosed by a plate 49 fitting be 7 tween the outside portion of the legs and secured thereto by welding, whereby an upper portion 0 of the press frameis formed and secured in spacedrelation from the base; .Said upper portion'has a spacing plank I0 and a hollow platen II secured at its lower extremity by bolts 52;

hose sections the lower legs of I-beams 41 will seat, it. being frame comprised of bars Ill for the sides and ends said channel is bored adjacent each of itscomers to slidably engage on the posts when vertically moved by inflation or deflation on the fire hose. Secured to'the upper side of the channel and movable therewith is a hollow platen 56 that reg isters in vertical alignment with the first said platen and between which glue jointed work may be placed to clamp the joints to snug engagement and cause the glue to set quickly by heat dispensed from the hollow platens, it being understood that the platens and fire hose have similar supply and exhaust arrangement to that described for the hose and platens in Figs. 1 and 2. A modification of the press shown in Fig. 9 is adaptalble for rpressing glued feathered jointed plies of wood 51 together, and in this instance, the upper and lower framemembers 58 and 59 respectively are secured in spaced relation by apost 60 at each end of the frame members, the

' lower portion of the frame seating on a suitable base 6|, the end elevation of which is shown in Fig.--9 and to which the posts are attached, each post being secured by nuts 62, one being above and one belowthe base. A pair of platens 63 and 64 are suitably secured to the upper and lower portions of the fram respectively, said platens confronting each other, the lower platen seating on a metal plate 65'to which it is secured, the ends of which extend outward from the platen and being bored to slidably engage on the posts, the plate being carried by a timber 66 as an adjusting element by varying the thickness thereof vertically, said timber to move vertically in a channel 61 formed on the top of the frame member 59 as actuated by a pair of fire hose 9 seated in the channel beneath the timber, and

the said hollow platens and fire hose sections being energized for their respective service similar to that described for Figs. 1 and 2.

The press illustrated in Figs. 10 and 11 con- 50 sists of a base plate 68 rectangular in form, and having secured theretoadjacent each of its corners a threaded post 69 extending upward therefrom, thetop of the posts lbeing connected by a thereof, also intermediate bars crossing the frame as supporting means for a hub II centrally disposed within the bar portions 'lll of the frame, said hub, being axially bored and threaded to carry a threaded screw element 12 on which 60 is secured a wheel 13, the screw as pendent carrying means for the press floating head that is comprisedof a similar frame to that above described but having a (bearing plate 14 to close the lower portion of the frame. The said frame has a sleeve 15 at each comer thereof to slidably engage on their respective posts, and the said frame being secured against upward movement when located, selectively, at a desired point vertically of the press by a threaded wheel nut 16 for each 70 post, whereby said plate H is secured a spaced distance upward from another floating plate 11, the corners of which are notched to slidably engage on said corner posts to avoid lateral displacement in its vertical movement, said move- 76 and to meet the hose sections lengths of fire hose juxsuflicient number to cov the ment being actuated by taposition'ed and in inner confronting area of last said plate and base plate 68 on which said flre hose seats, said fire hose being connected to a source for compresa sion similar to that heretofore described. It will now be seen the manner by which glue jointed work when placed between said plates 14 and I1 is pressed to cause snug engagement of the joints and retained the length of time required for cold hardening of the glue; furthermore the said floating plate may be substituted by hollow platens, steam heated, for quick setting or hardening of the glue.

Such modifications may be made as lie within the scope of the appended claims.
