PAUL L. WOSS, OF CHICAGO, ILLINOIS.

VENEER-GLUING PRESS.

Application filed July 1, 1915.

To all whom z't'mag concern:

Be it known that 1, PAUL L. Woss, a citizen of the United States, and a resident of the city of Chicago, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Veneer-Gluing Presses, of which the following is a specification.

My invention relates to improvements in veneer gluing presses, and has for its object the production of a device of this character whichwill be of durable and economical construction and efficient in use.

Other objects will appear hereinafter.

The invention consists in the combinations and arrangements of parts hereinafter described and claimed.

The invention will be best understood by reference to the accompanying drawings forming a part of this specification, and in which,

Figure 1 is a perspective view of a veneer gluing press embodying the invention, Fig. 2 is a partially sectional side elevation of the press, Fig. 3 is an elevation of one end of the clamping device of the press, with a plate removed to expose underlying parts and portions shown in section, Fig. 4 is an elevation of the opposite end of the clamping device, Fig. 5 is an enlarged section taken on substantially line mw of Fi 4, Fig. 6 is a fragmentary perspective view of one of the clamping jaws included in the invention, and Fig. 7 is a detail section taken on substantially line y of Fig. 5.

The preferred form of construction, as illustrated in the drawings, comprises a bed or table 1 which is supported upon legs 2. Arranged in opposite parallel edges of the bed 1 are channel guides or rails 3 which are rigidly secured in position.

Cooperating with the bed 1 is a clamping d'vice consisting of a carriage which comprises end members 4 and 5 which are positioned .at the opposite edges of said bed, and which are rigidly connected by a connecting member 6 which extends under the bed, as clearly shown in Fig. 5. Provided upon the inner sides of end members 4 and 5 are rollers 7 which engage in the channels 3 to loosely support the carriage, it

being clear that with this arrangement, the

carriage and hence the clamping deviceis free for adjustment along the bed to any position desired.

Cooperating with the upper side of the bed 1 is a plurality of clamping arms 8 each of which comprises an elongated body 9 which is hinged at one end as at 10, to the end member 4 of the carriage.

Cooperating with each clamping arm is a leaf spring 11 which serves to normally hold the free end of the former .in elevated or inoperative position, one end of said spring being secured to the end member 4, the opposite end thereof pressing against the under side of the adjacent: downwardly projecting end of the body 9. Also co operating with each clamping arm is a counter-balance weight 12 the purpose of which is to assist the spring 11 in normally holding the clamping arm in inoperative position. Each .weight 12 is connected with the corresponding clamping arm by means of a shank 13 which is fastened to the rearward end of the arm by means of a thumb nut 14 and a cooperating threaded stud 15, said stud projecting upwardly from the clamping arm through an elongated slot 16 formed in the shank, as clearly shown in Figs. 1 and 5. With the construction set forth, it will be seen that the counter-balance weight members are connected with the clamping arms in such a manner as to permit of adjustment so as to secure the desired balancing effect upon the clamping arms.

The clamping arm bodies 9 are locked in lowered or operative position by means of pawls 17 pivoted at 18 in the end member 5, said pawls being adapted for engagement with depending loops or staples 19 provided at the outerends of the members 9,

'as clearly shown in Fig. 3. A leaf spring 20 cooperates with eachpawl 17 for normally holding the same in operative pos1- tion, the arrangement being such that upon I lowering of any arm member 9 to operative position, the same will be automatically locked in this position through engagement of the corresponding pawl 17 with the corresponding loop or'staple 19. The pawls 17 are simultaneously rocked to releasing position by means of an exteriorly projecting in said pl ate.

handle 21 which is fulerumed at 22 in the end member 5. The inner end of arm 21 1s adapted to engage w1th one arm of a bell crank lever 23 which is pivoted at 21 in member 5, the other arm of said bell crank lever engaging with a plate 25 which is shiftably mounted upon headed pins 26 which engage with elongated slots 27 formed In the upper edge of plate 25 are formed shoulders 28 which are adapted for engagement with the lower ends of pawls 17, the arrangement being such that, upon shifting of the plate 25 to the right, as shown in Fig. 3, said pawls will be rocked to releasing position. The handle 21 is operatively connected with the plate 25 through the medium of the bell crank lever 23 so that upon dowi'iward rocking of the outer end of said handle, said plate 25 will be shifted as mentioned to effect rocking of the pawls 17 to releasing position. Hence with this arrangement, unlocking of the clamping arm is effected by simply depressing the outer end of handle 21. Upon release of said handle, the springs 20 acting through the medium of pawls 17, will shift the plate 25 back to its initial position, as

.shown in Fig. 3.

slidably engage openings 31 formed in the corresponding member 9. The openings 31 are reinforced, as seen, with metallic bushlngs. 1th this arrangement the aws 29 will be locked against longitudinal or horizontal movement but permitted free transverse or vertical movement. The under side of each aw is inclosed in a reinforcing protecting channel 32 formed of sheet metal which is secured in position by bolts and cooperating nuts 33.

Provided upon the upper end of each jaw 29 is an elongated plate 3-1, the correspond ing arm member 9 being slotted as at 35 to afford clearance for said plate. Each of the plates 31 is shiftably secured to the corresponding jaw by means of angular keepers 36 which engage with laterally projecting flanges 37 provided at the lower edge. of said plate, as clearly shown in Fig.

'6. Formed in each of the plates 3 1 is a pair of inclined cam slots 38 which are engaged by transversely extending pins 39 secured to the corresponding arm body 9. Vith this arrangement, it will be seen that vertical movement of any one of the clamping aws 29 may be effected by simply shifting the cam plate 3.4-. cooperating therewith. it being clear that upon shifting of said plate, the

pins 39 will engage with the longitudinal edges of the slots 38 cooperating w1th said jaw and thus effect raising or lowering of the jaw, depending upon the direction in which the plate is moved. Shifting of each plate 3+1 is effected by means of a lever 10 which is fulcrumed at ll to each of the arm members 9, the lower end of said lever being provided with an elongated slot 42 which engages with a laterally projecting pin 1-3 provided upon the corresponding plate 31. With this arrangement, it will be seen that shifting of any one of the plates 34: may be effected by simply tilting the corresponding lever 40.

In using the press, the veneer and the work to which the same is to be applied are arranged upon the bed 1. After the veneer has been placed as desired upon the work, the clamping arms 8 .are rocked downwardly to operative position, the same being automatically locked in this position by means of the pawls 17 as above described. When this is done, the clamping jaws 29 are pressed into secure engagement with the veneer through tilting of the levers 10, said jaws being locked in clamping position through frictional engagement of the plates 3-lwith the pins 39. In releasing the clamp ing arms, the levers A0 are first rocked to raise the jaws 29, whereupon the handle 21 is depressed to unlock the outer ends of said arms. This having been done, the springs 11 and counter-balance weights 12 serve to automatically rock the clamping arms upwardly to inoperative position.

Vhile I have illustrated and described the preferred form of construction for carrying my invention into effect, this is capable of variation and modification without departing from the spirit of the invention. 1, therefore, do not wish to be limited to the precise details of construction set forth, but desire to avail myself of such variations and modifications as come within the scope of the appended claims.
