WILLIAM SHEPPARD WALLACE or CHARL'OTTE;A 'NORTH cARoLrNA `TABLErme lPRESS Application 'filed May '23,

The object of my inventionis to `provide a novel and more eficient vtabletingpressV for the'use of printing oiiices in holding paper together until it can :be glued in pads,'and then holding the pads `under pressure While the glue is appli-ed and during the period required for the glue to dry.

It is an especial object of lmy invention to provide a device which will permit of gluing k a rlarge 'quantity of sheets at onetime andV wliicliwill maintain an even pressure on all parts of the pads. f

It is also an object of my invention to., provide a novel type ofspring, especially designed` for use as a part of myv tableting press.: It is also an 'objectof my invention tov provide a'device which is adjustable for use with dilferent sizesheets; and to provide the novel combination and arrangement of parts disclosed in the 4accompanying drawings, and described in the following specification.

I attainthese and other objects of my invention by the device. shown in the accompanying illustrations, in which,-v

Figure 1 is a side elevation of my inven tion in use; t n Fig. 2 is a front plan view of same;

Fig. 3 is a perspective'view of the spaced pressure blocks;V

Fig. 1.1r-.is a longitudinal section through one of the blocks; i

Fig. 5 is a detail-ed view of one of the springs, portions of which are diagrammatr cally shown;

Fig. 6 is a perspective view of diiferent size pads whichcan beheld and glued con. i veniently in my device; l

Fig. 7 is a si-de elevation of a modied and A preferred form of my invention; Fig. 8 is a face view of the bar 29with the spring section 151 attached; and

. Fig. 9 isa side elevation of same.,

. trough 7 which trough is kprovided with Like characters of reference designate like 192e.A serial No; 365,551;

suitable sidefstrips v8 to guide the pads of paper n thelower end. ofthe trough 7 isa rigid end strip 9, disposed at right angles to member 7'. l l

Iprovide a pair of blocks, one of which is designate-d llfand the other 12,' tohold the pads in'placeon the trough. ,Each of the blocks' 11 and 12. is provided vwith ak plurality.V of ' openings 22 and 24, arranged as shown inFigs. 3 andv 4 ofthe drawings. fl also pro'- vide y threev parallel grooves v19in; the outer surfaceof each of thel blocks 11. andr12, in whic'hgrooves. are mountedrthe hooks 2Q, 2.5, and 26.011 one oftheblocks; and the hooks' 21, 27 and 28 on the otherV block. Hooks 2O and-21 project over the ends jof the blocks; hooks 25 and 27,project'i'nto the openings 22; and hooks 26 and 28 project into the openings 24, vas shown in Fig. 3. i.

provi-de a` novel type of'spring comprising the spiral sections 15, 16 .and 17, with loops l8intervening between these sections and disposedatV substantially right angles to the plane of thespirals inthe sections; the

springs also having similar loops 18 at their ends. Any one of the loops 18 may be'liooked inthe hooks 2O and 21. s

, ,I provide a'suitable `hinge 6, ,having one of its arms affixed to the trough 7, and having the other arm a'ixed to the base 5,; the hingel being disposed in proximity to the triangular bracket 10. i y

lIn operation the trough may be disposed vin the position shown in Fig. 1, resting against the triangular bracket 10, whileV the sheets are being stacked on thev trough. .When the sheets to make up the ypads have been assembled, and the springsadjusted and fastened toithe respective blocksV 11V and 12, to place the.lsheets under pressure, ,the trough is turned to an upright position, thereby giv- Y ing the operator easy access lto the stack andY enabling him to remove samefwith little trouble after the glue has been applied'an'd allowed to dry, so as to place other stacks in f the trough.

between the sections of the springs `permit of hooking the springs for any desired-length to the respective end blocks 11 and l2, thus providing a convenientmethod of adjusting the springs to exert the required pressure on the paper to be glued. The: blocks ll and 12 are preferablypressed out of onensheet of metal, with the retaining hooks made apart of the blocks?,` but they may be separate elements as illustrated in the drawings, i'fprev erred. .e "'f y' y The inside of the metal blocks are covered Y with cork or felt to keep them from damaging or spoilingthe paper against whichthey are placed.

.Under the oldprocess now inzgeneral use, a printer hasto buy'a'separate lpair of boards foreach size of paper he desiresto pad, while my invention isadj'ustable so that any width of sheets 'from 1l finches .to 3 inches or less, such as .the2;pa'ds., B'andCfshown in lFig. 6, may beheldqin the device and glued together. i I

I may-provide a modification ofA myy invention in which insteadV of the novel type of springshownl utilize an ordinary'coil spring l5 inany suitable manner aiiXed' as at Slfto -a strip-of metal 29;this strip of metal 29( hav;-

ing severalspacedfholes 30 init which holes function in a similar manner and in place of they elements 18ct the coil spring shown in Figs. l and 24'.' This construction may be utilized in place of thecoil springs because of being cheaper to manufacture. The term, coilfspringsf as -usedin the vfollowing Y v claims shall be construed to include an equivavEL) lent; resilient device comprising'a coil `spring aiiixedkto a strip or" metal'and functioning in j approximately the same manner as the device illustrated. Y j

What I claim is:

ing a--plurality of loops disposed substantially at right angles to the planes of the coils` of the springs, whereby any of the loops may be engaged in the hooks of the blocks to adjustably exert Vpressure on pads Y `or sheets mounted between therespective blocks, the j blocks also having spaced apertures; and hooks projecting from'nthe Vblocks, and the said vhooks being engaged by the aforesaid springs for operating on sheets ofpaper of smaller 'size' than the blocks.V

` 3. A'tableting press, comprisingl a trough, a base, hinged means for mounting the trough onthe base, abracket for supporting v i the trough'in aslanting position, said trough having a :rigid end-member at the lower end for' supporting the contents of the trough,

apair ofbloclrs, each of said blocks having al plurality of hooks projecting from opposite ends ofsame,v anda series of coil-springs havingrat/plurality of loops disposed substan tially at rightangles to vthe planes of the coils of the springs, whereby any of theloops may bevengaged in the'hooks of the' blocks toad'ustabl exert ressu-re on ads orsheets- I.'
