1o alLwhO-m vit maycoiwern.- wBc it known that LfWInnIAM F. BARNES, of Rockford, in the countyof Winnebago and State of Illinoisyhave inventedcertainnew and useful Improvements in Machinery for Cutting Viaxintosheets, of which the followingis a specification. j

`My iuventionrelates to a machine v;for,cn tting wax ,into sheets by means of a knife traversing overa table,

and is principally `adapted to the manufacture of artificial owers. Y. Y The object of the. first part'of my invention is to out the waxintosheets, having a smooth surface, and to avoid. cloggingthe knife; and this I do hy causing the knife to move forward parallel with the table in cutting the` sheet, and then to rise and move backward over the table inan elevated position clear` of the uncut wax. j

The object of the next part of my invention is to cut the successivesheets of vuniform thickness, and this I accomplish-by combining, withthe cutter,.mechanisni automatically operatedgto feed the wax to the cutter. rlhe next part oi" my invention relates to the means of'raising and lowering the table on which -the wax rests; and this Ido by combining adjusting mechanism with the automatic feed mechanism. A

Thenextpart of my invention relates to the devices for Ivarying the size of the sheet to be ont; and this-I4 do by,coxnbining `with a rigid frameremovable frames of different sizes, as hereinafter` set forth. l My i mprovernent` further consists in constructing the bed-plate or table n-.wl1icl| the wax rests with a fixed central portion,` surrounded by interlocking.,slid` ing sections, to adjust the' table `to the size of the removableframe.; l f

The 4accompanying drawing represents a machine,

' embodying all the-improvements herein claimed.l Some `ofsaid improvements obviously may be used without others, and adapted to machines differing in constructionfrom the one herein shown.

Figure `1 representsaiplan or top view of my improved rnachine. A f 1 l Figure V2, ar verticailongitudinal central section through thesame', 'at the line a: afoffig. l.

Irigure' 3, an elevation of the same, as seen from. thetablc end. j y

Figure 4, a horizontal section through the same, on the line y y, fig. 2.

A suitable frame, A,`of wood ormetal, is'rmly secured upona proper-base. An open-box frame, B, is mounted upon this frame, of fwhich, inv fact,- I prefer thatitshould forma part. y `flo vary the size' of the sheets, I employ a series of `removable open frames, G, which .fit into thev boxvframes andrest upon ledges,c,`on the inside thereof.- 'lhese removable frames are prevented from rising by set screws, b, passing through the sides lof theboxframe into recesses into the removable' frame. The latter framesarealso made to converge slightly on theirrinner sides from bottom to top, to compress the wax as it rises, and deliver it to the cutter ina smooth compact condition. l

'i'.he table, D is mounted on an adj usting-screw, E, `and may bezsteadied by one or more guides, e, secured to. the under side of the table, and moving endwise through slots in the frame. The table is constructed, by preference, with an expan'sible top, consisting of a fixed central portion, d, and interlocking sliding sec# tions, d d", which may be adjusted relatively to each other, and to the central sectionv bymeans of holes and screws, as shown in iig. 1, or by slots and setscrews, the latter passing up through the table. By thisk means the table is adj usted to suitthe size ofthe loose frame.

The screw Eworks -in properbearings in the frame.

A bevel-gear, F,- is provided with a female screw,A through which the1-adjusting-screw Empasses. The gearl F Vturns freely on vthe screw, a corresponding pinion, g, on a shaft, G, meshes with the gear F, and is rotated by a crank, g1. `The table D istraised or lowered by turning this crank. f The wax is cnt or shaved into sheets by means of a knife, h, mounted in a stock, H, hinged -at its front end by pivots h to guide-blocks i, reciprocating in grooves in the frame.

The rear end of the 'stock H is pivoted to a crank, J, rotated by a winclror other proper means.

Owing to the relative arrangement4 of the drivingcrank J and stock to thev table, the knife, on its forward out, moves close to the upper edge of the open frame above which the wax projects, while,.in moving backward, the knife is elevated and moves clear ofthe wax, as shown in' fig. 1, where the arrows represent the direction of the movement, and the dott-ed lines the elevated position of the stock.

An arm, j, on thek crank J is provided with a series of holes at different distances from its center, to vary the stroke of a link-rod, 7c, connected with an arm, K, turning freely around-the screw E, (see fig. 4.)

This arm carries' a sprng-pawl, l, which takes into ratchet-teeth on the gear F. As this gear adjusts the table D, the latter is moved a given distance at every stroke of the knife, and as 'this movement equals the thickness of a sheet the uniformity of the latter is automatically secured.

It will be observed thatvthe relationsof the cranks Jj aresuch that the feed takes place vwhile'the knife is elevated and moving backward. A

The operation vof the machine will be readily understood from` the following description:

The table-D is run down to its lowestl positionv by turning the crank g'; the wax is placed on the table, and the loose frame O put on. rlhe crank J being nowtumed, the knife moves forward, making its cnt. At the same time the arm K carries the spring-pawl Zbaekward over the ratchet-teeth on the gear F, and

the table remains stationary. As the knife raises and moves backward the arm K is also retracted, the pawl turns the gear F, and the table is raised .the thickness of the sheet, to-be cut at the next stroke of the knife.

This thickness may be varied by setting the link 7c closer to or further from the axis of 'the crank J, and thus varying the traverse of the arm K and pawl l.

I claim as my invention- 1. Thecombination ofthe open box frame, to contain the wax, the stock carrying the knife., and pivoted to said frame, and the driving-crank, which both reciprocates and oscillates the knife, substantially as herein-y .before set forth.

2. The combination of the frame, the knife, the crank -which works the knife, the link-rod, driven by said crank, the arm and pawl vibrated bythe link-rod,

the elevating-gear, the feed-screw and the table, substantially as hereinbefore set forth.

3. The combination of theA table, the feed screw, the gear F, the gear g, for setting the table higher or lower prior to -the commencement of the, automatic feed,- and the automatically vibrated arm and pawl, whereby the gear F serves both to adjust the table and to feed the wax to the cutter, substantially as hereinbefore set forth. v

4. The combination of the knife, the automaticallymoving feed-table, the fixed open frame, and the removable frame, substantially as hereinbefore set forth.

5. The combination of the xed central portion of the table, with the adjustable interlocking sections, constructed as set forth.

In testimony whereof I vhave hereunto subcribed my name.

WILLIAM F. BARNES.
