SPECIFICATION forming part of Letters Patent No. 316,082, lated April 21, 1885.

Application filed February 14, 1885. (No model.)

fo all whom it may concern,.- y

Be it known that we, T. FRANK TYLER and EUGENE H. TAYLOR, both of Lynn, in the county of Essex and State of Massachusetts, have invented certain Improvements in Machines for Making BOX-Toes, of which the following is a specification.

This invention has for its object to provide an improved machine for cutting box-toe blanks and other like articles from a sheet of leather-board .or other suitable material, and forming or molding eachblank between a suitable male and female die and ej ecting the molded blank from the female die.

Our invention consists in the improvements which we will now proceed to describe and claim.

Ot' the accompanying drawings, forming a part of this specification, Figure l represents a perspective View of the principal portion of our improved machine. Fig. 2 represents a vertical section of the same. Fig. 3 represents an enlarged vertical section of a portion of the machine, showing a blank in position to be molded. Fig. 4 represents a perspective View of the female moldingdie. Fig. 5 represents a section of the molding-dies, show-3 ing their position when molding a blank. Fig.

' 6 represents a similar section showing the dies separated and the molded blank ejected. Fig. 7 represents a sectional view of the female die, showing the ejector and the devices for alternately holding and releasing it.

The same letters of reference indicate the same parts in all the figures.

In the drawings, a represents aixed bed or frame supported by a suitable standard, b, or

otherwise.

c represents a block or holder attached to the bed a, and provided with a removable female cutting-die, e.

f represents the male cutting-die, which is secured to a slide, h, the latter being attached to an arm, g, on avertically-sliding cross-head, Z. The cross-head is mounted on rods j j ,which slide in orifices inthe bed a and are connected at their lower ends by a cross-bar, k. A toggle-J oint composed of the links Z Z connects the cross-bar k with the bed a, as shown in Fig. 50 2. The meeting ends of the links Z Z are conder the cutting-dies.

nected by a rod, m, with a crank, n. on a driving-shaft, 0, the rotations of which reciprocate the cross-head t vertically through the described devices. At each descent of the male cutting-dief a blank for a box-toe, or other article which the cutting-dies are formed to produce, is severed from a strip of leather-l board or other material placed on the die e. The blanks descend through the female die to the bed a, and are moved one at a time by a 6o reciprocating feedingslide, p, to the female molding-die q, which is attached to the bed a, its upper surface being ush with that part of the bed along which the blanks are moved from the cutting-dies. 65

r represents the male molding-die, which is attached to the cross-head t' and enters the female die q at each depression of the crosshead. The feeding-slide is a thin plate of metal which moves in a slot or passage be- 7o tween the bed and the die-holder c, and is attached at its rear end to a block, t, which is adapted to slide in a channel, s, in the bed a.

'u represents an arm mounted loosely on a rock-shaft, c, which is journaled in arms att tached to the bed c. Said arm a has a slot in its upper end which receives a pin, e2, inserted in ears on the block t. The rock-shaft has a rigidlyattached arnnw, which is con nected by a rod, x, with a crank, y, ou the 8o driving-shaft 0, the rock-shaft being thus oscillated by the rotation ot' the driving-shaft. An arm, z, on, the rock-shaft bears against the slotted arm u and forces the latter, with the block tand slide p, backwardly when the rockl shaft is rotated, as indicated by the arrow in Fig. 2, thus drawing the slide p back i'rom un- When the rock-shaft is moved in the opposite direction, a spring, z', attached to the arm u and to the bed a, draws 9e the arm forward with the block t and slide p, causing the latter to move the bottom blank in the holder lforward to the forming-die q. Aspring, u, attached to the holder c and projecting over the slot through which the blanks are moved by the slide p, keeps said blanks in place onthe bed until they reach the formingdie q.

w' represents a gage-plate or stop, which is attached to the forming-die] and limits theioo t5 scribed isas follows:

forward movement of each blank. Said plate l q while the die r is descending and forming is adjustable by means of slots r r and screws Q Q a represents an ejectorin the die q, whereby 5 the molded blanks are expelled. Said ejector is composed of a rod or plungerinserted in an inclined or diagonal socket in the die q, and

normally pressed outwardly, as shown in Figs.` When a blank 3, 4, 6, and 7, by a spring, yb. is forcedinto the die'g by the downward movement of the die 1', the inclined ejector yields, as shown in Fig. 5, and when fully depressed is locked by apin or bolt, d', Fig. 7, entering the block, said bolt being crank lever, e', to which is piv'oted a vertical rod, f', passing through an orice in a flange on the cross-head z', and provided Ywith a spiral spring, g', n cros'shead v5 and a collar, h', attached to said rod. Vhen 'the cross-head z' descends,it compressesthe spring y', and causes the latter to depress the rod f', and thus turn the lever e, so as to force the bolt d into the die q. Vhen the ejector is fully depressed,a,recess,j, in its side coincides with and receives the bolt d, which locks the ejectorin the depressedv position shown. Vhen the cross-head i rises, it strikes a collar, k', on the upper end of the rod j", and raises `the latter sufficiently to cause it` to withdraw the bolt d from the ejector, which is thus released and thrown upwardly by its spring bf, thus throwing the molded blank upwardly with sufcient force to clear it from the die q. Theinclination of the ejector causes it to throw the blank upwardly and outwardly or laterally from the space in which the die 1^ t moves, so that there is no danger of the blank dropping or falling back in position to be again acted on by the die r. The ejectoris not released until the die r is considerably elevated, as shown in Fig. 6, so that said die does not prevent the expulsion of the blank from the die q.

The time of the various operations above de- Before each action of the cutting and forming dies the feed-slidep moves forward and deposits a blank onihe forming-die q. The cross-head then descends, causing the cutting-dies to sever a blank from o the sheet of material presented -to them, and the forming-dies to mold the blank last mov'ed forward. lyVhen the cross-head rises,the formed blank is ejected from the die q, the feed-slide \i s moved backwardly, and the blanks in the 5 holder c drop, so that the bottom blank lies in the path in which the feed-slide p moves. The slide then moves forward, as before, and pushes the bottom blank to the die q, and thus the operation is continued. It will beseen that i the operator has only to present the sheet of material to the cutting-dies, all the other parts ot' the operation beingk automatic. We prefer to time the movements of the feeding-slide p so that it will remain inthe'position it; occupies when it has moved the blank to the die pivoted to a bellwhich is interposed between the .as described,

the blank, the end of the slide actingasacontinuation of the guard w in preventing the lateral displacement of the blank. end of the spring a accomplishes the same purpose, so that the blank is held whether the slide p is timed as above indicated or not.

1. In a blank cutting and forming machine,

'the 'combination of the fixed and reciprocating cutting-dies, the fixed land movable 'formingdies, the reciprocating feeding-slides,whereby the blanks are moved' from the cutting'to the forming dies, and mechanism, substantially for. operating said movable cutting and forming dies and feeding-slide, as set forth.

2. The combination ofthe reciprocating and fixed forming-dies and the inclined or diagonal spring-ejector in the fixed die, whereby the formed blanks are ejected upwardly and laterally, as set forth.

'3. The combination ofthe reciprocating and fixed forming-dies, the spring-ejector in the fixed die, and devices, substantially as described, whereby the ejector is locked when depressed, and released when the reciprocating die is raised, as set forth.

4. The combination of the cutting and form- `ing dies, and the feeding-slidel of the spring u', whereby the blanks are held while being moved from the cutting to the forming dies, as set forth.

t 5. TheiiXedforming-dieq, having theguardplate w, combined with the reciprocating die 1^, and the feeding-slide, as set forth.
