JIG-FILLING MECHANISM.

To allwhom it may concern:

Be it known that I, PHILIP M. BUSH, a citizen of the United States, residing at Hartford, in the county of Hartford and State of-Connecticut, have invented anew and improved Jig-Filling Mechanism, of which the following is a specification.

My invention relates more especially to mechanism for filling jigs with parts that are commonly subjected to special operations while retained in the jig, or in the same relative positions which they occupy while in the jigs, and an object of my invention, among others, is to provide a jig filling mechanism that shall be extremely simple in construction and efficient and rapid in operation.

One form of jig filling mechanism embodying my invention, and in the construc-' tion and use of which the objects herein set out, as well as others, may be attained, is illustrated in theaccompanying drawings, in which I Figure 1 is a view of a punch press showing my improved jig filling mechanism attached thereto.

Fig. 2 is a detail view in vertical section of a portion of said press and of'my improved jig filling mechanism, especially illustrating the construction of the latter, the scale being enlarged over that shown in Fig. 1.

Fig. 3 is a detail view, scale enlarged, in horizontal section through the filling mechanism on plane denoted by dotted line 33 of Fig. 2 and looking in the direction indicated by the arrow.

Fig. 4 is a detail face view of the shears looking from a point at right angles to the plane of the shears, the scale'being enlarged.

Mechanism embodying my invention 15 shown herein as applied to a punch press for making small pieces included in radiator construction for supporting the tubes that conduct a fluid for the purpose of eool1ng gas engines, and especially those used in automobile construction. It will, however, be understood that my invention is not limited to use in connection with such a press, or

for making the pieces herein specifically shown, as it will. be found that it may be adapted to a wide variety of uses.

In the accompanying drawings the numeral 7 indicates the legs, 8 the base, 9 the shaft supports rising from the base, 10 the crank shaft, 11 the pitman and 12 the plun- Specification of Letters Patent.

Applieation'filed August 16, 1917. Serial No. 186,600.

- ger of a punch press, all of which may be feed mechanism being operated as by means of a connecting rod 16 attached to 'a crank 17 on the shaft 10, said feed mechanism also being operated by means of a lever 18 pivotally supportedand operated as by means of a lug 19 onthe side of the plunger 12. This feed mechanism may be of any ordinary and well known construction and further and detailed description is, therefore, omitted herein, it being stated, however, that this mechanism is such as to impart a step-by-step feeding movement to the strip of metal to pass it underneath the punch.

A base plate 20, comprising the immediate support for the lower dies of the punch press extends on opposite sides thereof, the feed mechanism being supported on one projecting end of said base plate and my improved jig filling mechanism being supported on the opposite projecting end of said guide for movement therealong jigs each comprising a base 26 and clips 27 that are set into grooves extending lengthwise along the base, said clips having fingers 28 formed to receive pieces 29 between them, which pieces are separated from the strip 14 after having been acted upon by the dies of the punch press to produce openings located at regular intervals lengthwise along said pieces. A rack 30 is secured to one edge of each jig, the teeth of the rack being formed to receive holding and feeding pawls to be hereinafter described.

An actuating shaft 31 is mounted for oscillating movement in supporting side parts 32 secured to and rising from the base plate 20, a strip supporting plate 33 and a strip guide plate 34 extending from one to the.

other of the side parts and being rigidly secured to the upper edges of said side parts. The strip guide plate has a guide groove forming a portion of a guide opening 35 through which the strip 14 extends and by which it is guided to cutting devices to be hereinafter described.

An actuating lever 36 is secured to one end of the shaft 31, and another actuating lever 37 is secured to the opposite end of said shaft 31. One end of the lever 36 underlies an actuating pin 38 that is adjustably mounted, as by means of interengaging screw threads in a lug 39 projecting from .the side of the plunger 12 so that an oscillating movement is imparted to said lever at each reciprocating movement of said plunger. The lever 36 on the side of the shaft 31 opposite the pin 38 and the corresponding part of the lever 37 project into openings formed byears 40 on opposite sides of a cutter or shear die .41 that is mounted for sliding movement against the face of a cutter supporting plate 42 that rests at its lower edge upon the bracket 21 and that is secured against the ends of the side parts 32 in any suitable manner. This. supporting plate has an opening 43, the upper edge of which constitutes a shear die 44 that coperates with the cutter 41 in severing the pieces from the strip 14 that is passed through the' against a nut secured upon the end of said rod. A justifier 47 is secured to the back or inner face of the cutter 41, this justifier consisting of a bar that is located in the opening 43 and that has fingers 48 located in position to pass into openings 49 formed by the punch in the strip 14, these fingers engaging the openings in the strip and thus properly positioning it so that all of the pieces 29 will be of equal width after having been separated'by the action of the shears.

I A pusher 50 is secured to a pusher shaft 51 mounted in the upper ends of brackets 52-53 secured to and rising from a bracket supporting plate 54 extending across the upper edges of the side parts 32, this, supporting plate having a groove in its under surface registering with the groove in the plate 34 and completing the guide openings 35. The free end of the pusher normally rests in a recess 55 in the cutter supporting plate 42, and it is moved out of said recess intermittently against the ends of the pieces 29 to push said pieces into the spaces between the fingers 28, the cutter 41, as it severs the pieces, moving them upwardly into the path of movement of the lower end is secured to the shaft 51. and is connected by a pusher operating bar 57 with the actuating lever 36, studs upon said arm'and lever passing through slots in said bar, and springs 58 connecting said studs with the bar, whereby a yielding connection between the lever 36 and arm 56 is obtained, so that should any of the parts become jammed the lever 36 may continue to operate without injury to the other parts.

In order to enable a substantially continual movement of one jig after another upwardly along the track 25 I provide two sets of feeding devices, to wit: an initial and a final feeding set. The initial set of said feeding devices comprises an initial feeding pawl 59 and an initial holding pawl 60, the former being pivotally attached to the end of the lever 36 andthe latter being pivotally attached to an arm 61 secured to and depending from the front edge of the base plate 20, as shown in Fig. 1 of the drawings. Springs 62 and 63 are connected with said pawls to move them into engagement with the teeth of the rack 30. 7 pawl disengaging cam 64 projects from the side part 23 in the path of movement of the pawl 59 as it is moved downwardly by the lever 36, the cam thus disengaging said feeding pawl from the teeth of the rack, the

latter being held at this time by theholding pawl 60.

The final set of feeding devices comprises afinal feeding pawl 65 and a final/holding pawl 66, the former being pivotallyfatta'ched to the end of the lever 36 and thelatter belng pivotally mounted on the bracket 52. Springs 67 and 68 are employed to move said pawls toward the teeth of the rack 30, as shown in Fig. 1 of the drawings. A camming pin 69 projects from the side of 'the bracket 52', to support the pawl 65 that rests against said pin. As the lever 36 is operated 'to move the pawl upwardly, the

curved edge of the pawl resting against said pin, and the location of the latter, allows the spring 67 to pull the pawl 65 into engagement with tlie teeth of the rack 30 and move the ig upwardly. In the downward movement of said pawl the rack is held against downward movement by the holding pawl 66. to the feeding of the strip 14, the punching operations thereon, the intermittent move ment of said strip underneath said punch and between the shear dies, and the intermittent movement of the latter to sever pieces from the end of the strip will be readily understood from the foregoing description taken in connection with the drawings illustrating my invention herein. The upward feed of the jigs will take place'itnermit-- tently by the action of the holdingand feed pawls hereinbefore described.- -When the A feeding The operation of the device as lower end of a jig approaches a point opposite the end of the-base plate 20, the pawls 59 and 60 will have ceased their action on said jig., At this time a new jig may be inserted in the track 25, its upper end being pushed into contact with, or nearly so, the lower edge of the preceding jig, and in this position the pawls 59 and 60 will immediately take up their operation to move the jig upwardly with a step-by-step movement, and as soon as the rack on said jig arrives in position for action of the pawls 65 and 66, the action of the two sets, of feeding pawls will be in unison and upon the same jig.

A justifier is positioned underneath the plunger 12 to enter the holes which have been formed by the action of the plunger and thus correctly position the strip for the action of the plunger. By the use of the justifiers 47 and 70 the sets of holes are formed at the same distance from each other, and in the severing of each piece from the end of the strip the holes are all located in the same position in each piece so severed. A stop 71 is secured to the base plate 20 to limit the movement of the lever 36 in the downward or-positioning movement of the pawls on said lever.

In accordance with the provisions of the patent statutes, I have described the principles of operation of my invention, together with the apparatus which I now consider to represent the best embodiment thereof; but I desire to have it understood that the apparatus shown is only illustrative, and that the invention can be carried out by other means within the scope of the appended claims.
