MACHIN POR MAKING BOOK-COVERS.

TO ALL TOWHOM IT MAX CONCERN:

Be it known that we,- MARsi-IALL RUMRELL and, ROBERT- H. 'RMRELL, of the city of lllrooklyn` county oi' Kings, sind State of New York, haveA made a certain new and useful invention, consisting in aMachine for Making all Kinds of Book Covers; and wc hereby declare that the following is u. full, clear, and exact description of tlie sanickrefcrence being had to the accompanying drawings, which form a part oi this specification, in

which- VFigure 1 represents a longitudinal section of our machine. v

Figure 2, a plan Vvicw'ofA the same, the top-plate being removed for better showing the working mechanism.

Similar ietters of reference indicate correspondinl` part-s in the several figures.

The-ordinary marmer of making boolc covers isentirely by hand. We have invented as a substitute our machine, which accomplishes the dil'l'erent operations more accurately, faster,1 and with much more neatncss.

The nature of our inventionconsists` first, in the inode of'taking up thes'ticning paper ane-l in holding the same; second, in means for' cutting the coverat the proper places to allow it 'to he folded at different angles; third, in means for pressingr the stiifening paper on theA cover, which has been previously supplied with paste,

thereby securing 4the former firmly to the latter; "fourth, in' means for turning the edges of the cover lovertlio sti'iening paper; i'ih, in nieans for removing certain sharp and thin metal plates over which the edges of thc "covers n r'bent; sixth, in securingthese edges, after havingbeen Afolded, firmly Aover the stii'ening paper matins been Wina bnir-e.

To enable others. skilledin the art toinake and' use our invention, we will proceed to describe. its construction and operation.

A, fig. 1, is thehcchplnte of our machine. In suitable place'snre recesses, a 'in which are placed the piles of stiffening paper. soine of the lattenbeing often thicker thnn others. The thinner ones are placed on plates, a2, which are held up by suitable springs,a3, so that the plunger and carrier, in descending,1 down-to the pile oi the thicker ones, issureto come down 'also on the thinner ones. *B is the-main hodyof the machine,

`whicli can inovc'lmck'on propcrnays onheil-plate A, se as toallow the press-bloch and carrier to passldown to the recess in A containing thc piles of stillening paper, In a suitable recess ou the top of B b is placed the cover to be opcrnt'cd on. C is the ,cnttcr-plat, ca trrying the knives c c e, which latter protrude.nbovc the face, of B through recesses loft therein.. The cutter-plate ,travels in slides on'B. Fasteneil to C are fourre-und rods, 'c c', sliding;l in suitable holes heft'in the body B.' They are supplied with collars above, against-which press coilsp-rings. e2, which rest-with their other end on' B, tending so to hold up the .rods el, and with them 4the cutterpluie C and the knives c. The rods el, being acted on by suitable means andv depressed, 'will carry with thern the knife-plate U. and with the latter the knives c e, which latter,being very sharp andof peculiar form, as shown in the drawing. on their undercdges, sindV nt'theseme time pnssingthrongh Anice-fitting slots, will'cut the cover placed on recess-[1 at theplaccs required. The knives c c,having passed belowv the top fucc'of B',.s:1itable spring catches, c" c, arrest them with the cutter-plate to allow other operations to go on.V These spriiig catches, when actuated or drawn back by' rods, c* c, will release the cutter-carricr,'and theknives and rods cwill be carried up hy the action of 'the coil-springs cz under the heads of the' latter, By these means -t'he knives are brought again above thc recess I1 ready tocut the next cover to'. be placed thereon; vD is thepess-platc and widening-paper carrier, secured bystanchions, E E. It has lugs, F, projecting outward, so arranged as to act on rolls I." c. 'v these means thc knives are werkedwheu the press-block. is lowered. d d d are little vessels lllellnifh mucln'le or' other stickinoV material communicatin b ver small holes, to tho lower face of the r: i. o 7 g y y press-plate; :i little'inncilage is, therefore, always protrndingfroin the'facc of the press-plate, and light bodies, such :is the sli'cning paper, will adhere tothe 'saine if brought in' contnct'thercwith. By these means the slim-ning pepers are takt-n from the receptacle in 'which they arepilefl up .in thebed-plat" A, as bcil'orexlescribcll. 0n the lower face. of the pressi-block D,'a' little -distance away therefrom, is a plate, II, of exactly the some shape as D, similar, hut mueller. than thc recess b, leaving an equal space all around. Between the plete, H and the face of D are plneed Four or more plates, G G, adjustable freni their first position, when they are even with the for the purpose herein set forth,

press-block, all .around outward to' tlieiextont ofv` the distance 'that '.the press-block D is smnlleif thnn the 'recess I. Forming son very thin plete-,rim around the bottom ci'v D, of thecx'nct Form of the recess.
