4 Claims.

This invention relates to paper padding presses or devices which assemble pads of paper preparatory to applying the binding adhesive thereto.

The principal object of the invention is to produce a simple press structure which is easily manipulated and possesses the requisite pressing the piled sheets of paper. a

A further object is to produce alight-weight yet rigid structure which may be shipped in knocked-down form and readily assembled at the place of use.

With these and other objects in view the invention consists in the structure and combinations and arrangements of parts hereinafter described and pointed out with particularity in the appended claims.

p In the accompanying drawings illustrating a practical adaptation of the invention,

Figure 1 is a front elevation of the press;-

Figure 2 is a top plan view;

Figure3 is an end elevation; I

Figure 4 is a fragmentary vertical section, on an enlarged scale, taken on or about the line 4-4 of Figure 1;

Figure 5 is a horizontal section on the line- 55 of Figure 4; and

Figure 6 is a horizontal section on the line 6-6 of Figure 4.

Referring now to the drawings, the numeral iii designates the base plate or board of the press which may be conveniently made of wood, prefl erably of the character known as ply-wood.

Obviously, however, it may be made of metal or any other suitable material.

As shown, the base plate or fered on its upper face along its opposite end portions, as at El. Extending across one longitudinal side portion of the base "iii is a rectangular frame or yoke E2 of substantially inverted U-shape and of channelled cross section This frame may be made of a single metal section and bent into the form shown, or, obviously, it may beformed of separate members and welded or otherwise secured together in any approved manner. At the opposite lower ends of the vertical leg portions of saidframe or yoke l2 bolts 53 are attached or formed integrally therewith; preferably by welding, as shown more clearly at M in Figure 5. These bolts l3 are inserted in openings provided therefor inthe'base ill, which openings are countersunkat' the under side of the base for the reception of nuts l5.

Extending horizontally near the intermediate upper portion iii of the yoke or. frame: i2 is a board ii] is cham-.

cross member ll which is welded or otherwise secured at its opposite ends to the adjacent leg portions ofthe frame, this cross member preterably being an inverted channel.

Depending vertically from the upper cross member it, near the vertical legs of the framev i2, is a pair of tubes l3, while opposed to said tubes in axial alignment therewith is a pair of tubes l9 extending upwardly from the lower cross member ll, each of said tubes being rigidly securedto the respective cross member, preferably by welding. The aligned tubes l8 and 59 have smooth bores of the same diameter and extending therethrough are elongated screw. elements in with free longitudinal movement there- .in, said screw elements being held against rotation during their longitudinal movement by being provided with longitudinal grooves H (see- Figure 6') to receive splines or key members 22 which are fixed on the tubular members it or it. For practicalpurposes, it is only necessary 'to provide the spline or key 22 on one of the opposed sleeves H3 or it, and as shown this memher is provided only on the lower sleeve iii,

interposed between the respective upper and lower sleeves l8 and it are hand wheels 23, the

hub portions 2% of which have'screw threaded I bores to fit the screws 2%, and as said hub portions 2:! abut the adjacent ends of said sleeves it and E9 the hand wheels, of course, are held against endwise movement during rotation. Consequently, when said wheels are rotated the screw elements 22 are causedto move endwise, either upwardly or downwardly, according to the direction of rotation of the hand wheels, and due to the threaded engagement of the hub portions 2% with said screw elements at. Any suitable anti-friction bearings may be provided between the abutting ends of the tubes l8, Land the hub portions 24 of the hand wheels, but, as shown, a ball bearing 25 of any conventional type is interposed between the lower end of the hub 26 and the end'of the lower sleeve it, while between the upper sleeve is and upper end of the hub 26 a washer 26, of bronze or other suitable anti-friction metal, is provided, as shown in Figure 4. However, as just previously noted, any other suitable provision may be made for the purpose of end thrust bearings between the hub limited relative movement therebetween. Preferably, they are rigidly secured, and the outer end of each foot element is extended into the adjacent channeled leg portion of the frame or yoke I2 with freedom to move vertically therein whereby to be guided in operation and held against rotative movement about the axis of the companion screw element 20. As shown, the attachment of the foot element 2'! to the screw element 20 is effected by welding a triangular upstanding flange or lug 28 centrally upon the upper side of the web of the foot element and slotting the end portion of the screw element as at 29 (see Figure 4) to receive said flange or lug 28 and welding the parts together, as indicated at 30. Welded or otherwise secured tothe under side of each of the foot elements 21 is a presser plate 3! of lesser length but of greater width than the foot element.

The yoke or frame I2 is braced by end plates 32 which are flanged at both front and rear vertical margins, as at 33 and 34, and also at their lower margins as at 35, in order to give rigidity to the plate and provide means for its attachment to the frame or yoke I2 and also to the base it), as will now be described.

The vertical flanges 33 of the plates 32 are provided with a longitudinal series of apertures through which attaching screws 36 are inserted into aligned screw threaded apertures provided therefor in the abutting flange portions of the leg members of the yoke or frame l2. A correspo'ndingly apertured reinforcing bar 31 is preferably provided on the outside of the .flange 33, which not only affords a stable securing means for the flange but adds to the rigidity of the leg portions of the frame or yoke IL. The bottom flanges of said plates 32 are provided with a series of apertures to receive attaching screws 38 which are inserted through openings provided therefor in the base In, which openings are countersunk at the under side of the base to receive the securing nuts 39.

The structure is further braced by the provision of triangular gusset plates 40 which are flanged along one right angular marginal portion thereof, as at M which overhangs the upper marginal portion of the plate 32 and is secured to the plate by screws or bolts 42, and said plates 40 are detachably secured along their other right angular marginal portions to the lower horizontal frame member I! by screws or bolts 43. In this connection, also, it is preferable to bolt the meet ing end portions of the two gusset plates together, by the same bolt or screw 44 which attaches them to said cross member ll of the frame (see Figure 1). It is preferable to further reinforce the yoke or frame l2 by welding or otherwise securing a truss member 45 on top of the upper cross memher it of the frame l2 and providinga strut 46 between the raised middle portion of the truss 45 and the cross member it. This truss member 45 is provided with openings 47 for the free passage of the upper end portions of the screw elements 26, and, obviously, said cross members i6 and H of the frame or yoke !2 are likewise provided with suitable openings aligned with the sleeve members l8 and 3 for the passage of said screw elements 20.

From the foregoing it is noted that a knockeddown structure is produced which is comparatively light in weight yet possesses the inherent rigidity requisite for a device of this character, and the general arrangement of the device is such that the. paper sheets may be conveniently the vertical leg portions of the frame or yoke 12,

said flanges being providedwith inclined slots 50 to hook over shouldered studs or buttons 5| provided therefor on the vertical frame members, whereby said evener plate or jogging board is readily placed upon and removed from the frame. To give the desired rigidity to the plate 38 its lower marginal portion is flanged outwardly, as

at 52, which portion also serves as a convenient grasping means for placing and removing the plate, while at the upper portion the plate is flanged inwardly, as at 53, to abut the outer flange of the cross member H.

In the use of the device, plate 48 is placed on the frame or yoke l2 and the piled sheets, indicated at 54 under the left presser plate 3| or under the other plate, or'both plates, as may be the case, are pressed edgewise against the plate 38, and after the presser plate is brought to bear upon the piled sheets through the instrumentality of the cooperating hand wheel 23 and screw elements 253, said plate 48 isremoved and the exposed edge portion of the pressed pad is ready for the application of the binding adhesive.

Obviously, the structure may be modified in many respects within the spirit and scope of the invention as defined by the appended claims. The invention, therefore, is not limited to the specific construction and arrangement shown in the accompanying drawings.
