.lMPROVEMENT IN MACHINES FOR MAKING HEADS OF WOODEN BOXES.

I Specification forming part of Letters Patent N 0. 169,700, dated November 9, 1875; application filed September 22, 1e74.

To all whom it may concern:

Be it known that I, EDMUND HERSEY, of Hingham, in the county of Plymouth and State of Massachusetts, have invented certain new and useful Improvements in Machines for ()utting Wooden Heads and Bottoms for Boxes, and for other articles, of which the following, taken in connection with the accompanying drawings, is a specification:

My invention relates to a machine for cut ting the bottomsand heads of wooden boxes, the bottoms of wooden 1')ails,-barrel-heads, and various articles too numerous to mention here; and itis an improvement upon themachine patented to me March 12, 1867, and

.M y invention relates, more especially, to the arrangement of the cutters, and to the means employed to operate the reciprocating plungers and control their action; and it consists, first, in securing said plungers to the opposite ends of a toothed rack, fitted to slide in a suitable bearing formed for the purpose in a stand, bolted or otherwise secured to the frame,in the center of its length, and suitable gearing to impart to said rack a reciprocating motion, and a'shipper-lever,acting upon a clutch or sliding gears, for the purpose of re-, said rack and plungers.

toothed rack and plungers a shipper rod or bar, arranged to be moved endwise in either direction by saidplungers, and provided with pins or shoulders upon either side of the shipper-handle, as a means of automatically moving said shipperhandle, to disengage the gearing and stop. the motion of the plungers. It further consists in theuse upon said shipperbar of a pointed pin or lug projecting downward therefrom, in combinationwith a stationary double incline, over which said point travels at each motion of said bar, and thereby raises the shipper-handle, and disengages it from the lockingdevice. My invention further consists in the use of a safety-guard, placed slightly in front of the extreme point of the cutting-edge of the knife, to prevent the operator from getting his hands against the cutters.

In the drawings, Figure 1 is a plan view of my improved machine. Fig.

2 is a longitudiq nal section on line or ac. Fig. 3 is a transverse section on lineg 3 on Fig. 1. Fig. 4 is a transverse section on line z 2' on Fig. 1, and Fig. 5 is a detail illustrating the shipping device.

A A is the frame of the machine, and B B are two knives or cutters, made in the form of hollow tubes, and held in fixed positions at opposite ends of the frame A, to which they are secured by the clamps B Said cutters may be cylindrical, oval, or of other desirable form in cross-section, and have their front or cutting ends ground to a circular or oval shape, (see Fig'. 1,) with an exterior bevel, so that the cutting-tube is considerably shorter on the two sides than upon the top or bottom, so that when a blank is presented to the cutter, the cutter will first strike the blank at the top and bottom, and, as the blank is fed along the cutter will cut away the surplus wood, by a drawing cut, in four dili'erent directions, in the same manner as in the case of the machine patented to me, as before referred' to. O O are two guide-boxes or chutes, into which a pile of blanks or square pieces of boards, of suitable thickness to make box bottoms or covers, may be placed, each blank resting upon its edge on the bottom of the chute O or C,with the grain of the wood in' a horizontal direction, and at right angles to the line of motion of the plungers. D is a toothed rack fitted to move endwise in a dovetailedbearing formed in the stand E, secured tothe frame A in the center of its length. and

D and D are blocks of wood, secured one to each end of the rack D, and serve as plungers to force thepile of blanks through the cutters. F is a pinion mounted on the middle of the shaft G, in position to engage with the rack D, said shaft G being mounted in the bearings H H, and having secured to its other end the large spur-gear wheel I, which engages with and is driven by the pinion J, secured upon the end of the shaft K, which also has secured thereon the two bevel-gear wheels L and L, and is so mounted in the bearings M M that it is free to revolve therein, and at the same time it may be moved endwise therein.

N is the main drivin g-shaft, mounted in the bearings N N,

with its axis at right angles to -the shaft K,'and having securedthereon the driving-pulley O and the'bev'el-gear wheel formed therein'for the purpose. R is a shipper rod or. bar, fitted to suitable bearings directly under,'and parallel to, the toothed rack "D, and provided with the pins 0 and c, andd and d, projecting upward therefromfas seen in Fig. 2. The pins 0 and c are placed one upon either side of the handle or long arm of the shipper-lever Q, and by contact therewith, when the bar It is moved endwise, said shipper-handle is moved in the same direction the bar is being moved, and thereby disen= gaging the gears L or L from the gear P, and stopping the motion of the plungers D and D The pins cl and 01 extend upward so far thattheir upper ends are directly in the path of the plungers D and D, which, respectively,

strike said pins d and d alternately just be fore-they reach the extreme of their back- -ward:stroke, and thus cause the bar B to move endwise until one of the pins 0 or c strikes the 'shipperhandle, as above described.

.beveled or pointed lug, e, projecting down- The'bar It is also provided with a ward fromits under side about equidistant from the pins 0' and c, which comes in con- I tact with, and rises over, the double-inclined surface of the girt f, which causes the end of the bar It, and through it the shipper-handle Q, to be raised sufficiently to disengage said shipper-handle from the'holding-catch g before-the pin 0 or 0' comes in contact .therewith to move it forward.

The operation of my improved machine is as follows: Suppose the rack D and the plunx gers D and 1) to be at the extreme end of their motion to the right, when the guide-box .0 will be clear, and may be filled with blanks, set on edge, say to the number-of fifty, more or less. Now, if the shipper-handle be moved into the position shown in the drawings, where it is held by the catch g, the bevel-gear L will be engaged .with the gear P, and the rack D ,Willbe moved endwise, carrying the plunger D toward the left-hand end of the machine,

and forcing the pile of blanks, previously placed in the .guide-box O, toward and against the cutting-edge of the tubular knife B, whichv cutsaway the surplus wood, reducing each blank in succession to a uniform symmetrical shape, exactly conforming to the interior shape of the knife, through which they are forced and delivered from its outer end. This motion ,continues until the plunger 1) strikes the pin d, and moves the shIpper-barR endwise until the pointedlug 0, moving up the inclined surface'ofthe girt f. raises the shipper-handleQ from thecatchg, and the pine comes in contact with said shipper-handle and moves it far enough to disengage the I gears P and L, when the motion of the machine will cease. with the plunger D in a position to admit of the guide-box G being filled with blanks. This being done, the shipper-handle Q is moved by hand to the left, so as to engage the gears L and P, where said lever is held by the opposite end of the catch y, when the machinery is again set in motion to move the rack D and its plunger D from the left to the right, forcing'the pile of blanks through the cutting-tube B and delivering them at its outer end, said motion continuing until the plunger D strikes the pin d and moves the shipper-bar R endwise in the same direct-ion that the plunger is moving, until the pointed lug e is moved up the other inclined surface of the girt f, raising the end of the bar R and the shipper-handle Q, and disengaging it from the catch g, when the pin 0 will strike the shipper-handle and move it tothe right until the gears L and P are disengaged, when the motion of the mechanism will cease.

S and S are guards to prevent accident by the operators ha-ud coming in contact with the knife.

Instead of the guide-boxes G and 0', plain tables may be used with a gage-bar, said table answering to the bottom of said boxes, and the gage bar answering to the back upright side of said box.

What I claim as new, and desire to secure by Letters Patent of the United States, is-

1. The combination and arrangement of the knives B and B, the toothed rack I), having secured to its opposite ends the plungers D andv D and the pinion F, arranged to be intermittently rotated in opposite directions, and thereby impart a reciprocating motion to the rackl) and plungers' D and D as and for the purposes described.

2. The combination of the knives B and B formed as set forth, the plungers D and D rack D, pinion F, gear I, pinion J, sliding shaft K, bevel-wheels L, L, and P, and shipper-lever Q, all arranged to operate substantially as described.

3. The combination of the reciprocating plung'ers'D and D, the shipper-lever Q, catch g, the shipper-bar It, provided with the pins 0, 0, cl, and d, and the pointed lug e, and the double-inclined upper surface of the girtf. arranged to operate substantially as described.

4. In combination with the knives B and B one or both, the safety-guards S or S, arranged substantially as described, for the purposes specified.

Executed at Boston this 14th day of September, 1874.
