This invention relates to paper padding machines, and more particularly to a paper padding or tableting press used for aligning a stack of paper sheets and for clamping said sheets so that they may be glued.

A main object of the invention is to providea novel and improved paper padding or tableting press for aligning, clamping and gluing a'stack of paper sheets, said press being simple in construction, being easy to operate, and being readily adjustable for padding or tableting a wide variety of sheet sizes and quantities without requiring the use of special fillers or the like.

A further object of the invention is to provide an improved paper padding or tableting press which involves inexpensive parts, which is rugged in construction, which is easy to manipulate, and which enables the user to accurately center the clamping frame thereof on the pads of paper being tableted quickly and with a minimum amount of labor, whereby a stack of paper sheets may be conveniently clamped and held in proper position for gluing.

. Further objects and advantages of the invention will become apparent fromthe following description and claims, and from the accompanying drawings, wherein: v

Figure 1 is a top view of an improved paper padding press according to the present invention,

showing a stack of sheets of paper clamped in the machine preparatory to gluing.

Figure 2 is an end elevational view of the apparatus of Figure 1, taken from theleft end thereof as viewed in Figure 1.

Figure 3 is an end elevational view of the apparatus of Figure 1, taken from the right end thereof as viewed in Figure 1.

Figure 4 is a fragmentary perspective view of a portion of the paper clamping frame employed in the apparatus of Figure 1.

Figure 5 is a fragmentary cross sectional view taken on the line 55 of Figure 3.

Figure 6 is a top plan view of the stock trough employed in the apparatus of Figure 1- Figure '7 is a perspective view of the movable clamping member employed in the clamping frame forming part of the apparatus shown in Figure 1.

Figure 8 is an elevational view of the clamping frame in upright position showing a stack of paper sheets clamped therein preparatory to gluing of the sheets, after the clamping frame has been removed from the stock trough.

Referring to the drawings, the paper padding press is designated generally at II and comprises a stock trough l2 which comprises a pair of fiat boards l3 and M mounted on respective end frame elements l5, It, the boards being rigidly secured to the end frame elements and the end frame elements being formed to support the boards in longitudinally extending positions at right angles to each other, to define a rightangled V -trough. Projecting outwardly from the inclined arms ofthe frames 15 and [5 which underlie the board 53 are the respective spaced pairs of pins l6 and I1.

Designated at [8 is the stock clamping frame, said frame comprising the respective corner posts I9, 20, 2! and 22, the posts It and 26 being connecte'd by transverse bars 23, 24 and 25, and the post members 2 I and 22 being connected bytrans- The corner post members 7 l9 and 2| are connected by a longitudinal bar 28,

verse bars 26 and 21.

members 23 and 24 is a jack of conventional con-,

struction, 'designatedat 32, said jack being providedwith the pivoted operating handle 33 andwith the longitudinally movable jack rod 34 which extends in longitudinal alignment with the plate member 3i and which is provided at its inner end with the clamping plate 35 which opposes the plate member 3!.

The bar members 25 and 27 have depending vertical flanges which are formed with the spaced notches 36 arranged to be selectively engaged with the pins l6 when the frame I8 is disposed on the stock trough I2 in the manner shown in Figures 2 and 3. As shown in said figures, the frame i8 may be arranged over the stock trough with the pins l6 engaged in selected notches 36 in the res spective bars 25 and 21 while the lower portions of, the bars are supported at their edges on the remaining pins H. A stack of paper to be padded may then be placed in the stock trough between the stationary clamping plate 3! and the movable clamping plate 35 and the sheets of said stack may be accurately aligned in registration with each other by abutment with the respective supporting boards l3 and, said boards being located at right angles to each other, as above described, whereby the corners of the sheets are accurately positioned in registration with each other. The stack of sheets is then compressed by operating the jack 32 to clamp the sheets betweencentral portions of the stack of sheets, and the notches 36 allow the clamping frame to be accurately positioned in substantially centered relationship with respect to the stack of sheets, regardless of the actual sizes of the sheets being padded. If the sheets of paper are of substantially larger area than the clamping plates 31 and 35, auxiliary boards 40 and 4| may be employed adjacent the clamping plates 3| and 35, as shown,in-Fig,ures1,,2 and 3,110, distribute the pressure on the sheets when the clamping force is applied thereto.

After the sheets have been clamped in theframe [8 in the manner above described, the.

frame is removed from the stock trough and placed in the upright position thereof shown'in'.

Figure 8, whereby the aligned edgesuof the. sheets may be covered with glue or other suitable adhesive material. glued or adhesively secured at their edges, the clamping. force may be-relieved andthe padded sheets may be removed.

From theabove description it willbe app rent.

that a quantity of sheetsof paper may. be readily glued together, into pads, and that the apparatus, allows the padding of a Wide variety of sheet sizes,

and quantities without the use of any-fillers or other, devices, except that. the auxiliary pressure-- distributing. boards 40 and 4 I- may beemployed for sheets of relatively large size. Furthermore,-a plurality of padding frames I8 may be employed with the same stock trough, since the, frames 48 Therefore, it is intended that no limitations be placed on the invention except as defined by thev scope of the appended claims.

What is claimed is: 1., In a paper padding press, in combination, a stock trough having two inclined surfaces at right angles to each other, a clamping. frame-arranged After the sheets have beenthus to receive and clampingly hold a stack of paper, a plurality of pin elements on each end of one of said inclined surfaces, and respective depending flanges at the ends of the frame, said flanges being each formed with a pluralit of spaced notches adapted to be selectively engaged with one of the pin elements at an end of the said one of the inclined surfaces to support said frame in a selected position relative to said inclined surfaces, wherebya stack of paper maybe arranged for padding by engagement with said inclined surfaces, prior to clamping said stack in the frame.

' 2 Inapaper padding press, in combination, a stock trough having two inclined surfaces at right angles to each other, a generally rectangular clamping, frame, a stationary clamping member at one end of the frame, a movable clamping member carried. by the other end of the frame opposing said stationary {clamping member and being arranged to clamp astack cfpaper against the'stationary clamping member, a plurality of pin elements on-ea-ch end of onelofsaid-inclined surfaces, and respective dependingflanges'at the.v ends of the frame, said flanges being each formed,

With a plurality of spaced notches adapted to be selectively engaged with one of the pin elements, at an end of the said one of the inclined surfaces tosupport said frame in a selected position relative to said inclined surfaces, whereby a stack of paper may be arranged for padding by engagement with said inclined surfaces, prior to clamping said stack in the frame;
