FEED MECHANIC]! FOR HEADING-MACHINES Specification of Letters Patent.

Patented May 31, 1910.

Application filed April 28, 1909. Serial N0. 492,732.

To all whom it may concern:

Be it known that we, ANDREW C. CAMP- BELL and NORMAN W. OUMMINS, citizens of the United States, residing at Waterbury,

in the county of New Haven and State of Connecticut, have invented a new and use- Improvement in Feed Mechanism for Heading-Machines, of which the following is a specification.

This invention relates to a feed mechanism for those machines in which, by means of a punch and die, small metallic pieces or blanks are upset and headed, or punched, or trimmed, or re-headed. This feed mechan ism is designed to receive the blanks to be headed, re-headed or trimmed, and carry them laterally into accurate alinement with the axis of the die opening and punch.

The object of this invent-ion is to provide a very sim le, easily 0 erated,'and accurate feed mec anism, which will take the blanks from one side of such a machine, and carry them inwardly and downwardly into the desired position, the movements of the parts of the feed mechanism being such that the fingers carrying the blanks, in their upper position move substantially horizontal, for a short distance, so that the blanks and fingers will clear the frame, and all mechanism mounted thereon, and in their lower position move substantially vertical, for a short distance, so that the blanks will be carried into exact position and the fingers will avoid the die and punch mechanism.

Figure 1 of the accompanying drawings shows a feed mechanism which embodies this invention applied to a simple t e of heading machine. Only so much 0 the general mechanism of this header is shown as is necessary to illustrate the relation and action of the feed mechanism. Fig. 2 shows, on larger'scale, aside elevation of the feed mechanism, and a portion of the machine frame. In this view the upper or receiving positionof the feed mechanism is shown in full lines, and the lower or delivery position is indicated by dotted lines.

Mounted transversely of the frame 1 of the machine illustrated, is the main shaft 2, which has the usual fly wheel 3 at one end, and, between the sides of the frame, the crank 4. This crank is connected by a pitto move back and forth in ways? that extend along 'wardly from the side of the frame,

the inside walls of the sides of the frame. The gate carries a punch 8, which, as the shaft is rotated and the crank revolved, is reciprocated toward and from the die opening 9. The punch and die may be constructed in any common way and may have any desired conformation.

The feed mechanism which embodies the present invention, is capable of receiying blanks from anylcommon form of delivery mechanism, or from the hand of the oper ator. For simplicity, as the blank presenting mechanism forms no part of'the present invention, the feed mechanism isillustrated as receiving blanks passed to it by hand.

Supported by a bracket 10, projecting inis a short rocker shaft 11. On one end of this rocker shaft IS an arm 12, which is connected by a hnk 13, with a rocker arm 14 that is mounted on a rocker shaft 15. This shaft, which is supported by brackets 16, has a rocker arm 17 bearin a roll 18,. which is held in engagement with the cam 1.9 on the main shaft. A spring 29 may be arranged be tween the arm 14 and the frame, for the purpose of keeping the roll 18 against. the cam 19.

Extending from the rocker shaft 11, is a rocker arm 20. A block 21 is swiveled to, or pivotally connected with, the upper end of this rocker arm. This block has a forwardly extending arm 22' carrying a pair of spring fingers '23. Projecting backwardly from the block 21 is a rod 24. This-rod extends through and is free to'move longitudinally in an opening through the guiding block 25. This gulding block is swiveled in the top of the bracket 26, that is attached to the top of the end of the frame of the machine. The axis of the swiveled guiding block 25 is located directly over the axis of the unch and the die opening. The length of t e arm 20, from the axis of the rocker shaft 11- to the axis of the pivot of the block 21, isequal to the distance from the axis ofthe rocker shaft 11 to the vertical lane passing through the axis of the swivel lock 25'and the punch and the die opening.

With this mechanism the pieces or blanks to be headed, re-headed, or trimmed, are inserted, one at a time, horizontally, by hand, or any common mechanism, between the horizontally extending spring fingers. When the machine is in operation, the rocker arm 20 turns on the are indicated by the dotted line 27. As this arm moves-through this are, the rod to which the spring fingers are connected reciprocates longitudinally throu h the swivel block mounted on the fixed racket, which block at the same time turns on its axis, so that the rod with the spring fingers moves from the horizontal position shown in full lines, to the vertical position shown in dotted lines in Fig. 2. This movement of these parts causes the fin-' ers to car the blank through the course indicated by the dotted line 28, from the horizontal position, where the fingers receive the blank, to the vertical position between the punch'and die. When the rocker arm moves upward the blank holding fingers move through the same path, but of course in the reverse direction.

As the arm 20 starts when feeding a blank, from a vertical position, the downward trend of the are is at first but little, consequently, for ashort distance the first part of the movement of the fingers is ractically horizontal. ,This carries the b ank so that it clears the frame and any mechanism mount- I ed thereon. As, during the last portion of its movement, the arm 20 is almost horizontal, and the rod and fingers are in a vertical position, the last part of the movement of the fingers and blank is ractically vertical. This action causes the ngers to bring the blank into accurate line with the punch and die and to snap off from the blank after it has been grasped, without interference with the die and punch or any of the o ratin mechanisms connected therewith. ith this organization, the arm 20 might stop more or less above or below an exact horizontal position, in order to aline the blank horizontally with the die, without carrying the blank materially out of the vertical plane which passes through the axis of the die. As a result of this, the blanks are fed accurately and are always passed properly to the die.

The invention claimed is:

1. The combination in a feed mechanism for a header, of fingers adapted to receive a blank, an oscillatory support for said fingers,

a swiveled guide for said fingers, and mechanism for oscillating the sup ort.

2. The combination in a eed mechanism for a header, of fingers adapted to receive a blank, a rocker arm supporting said fingers, a pivotal connection between the rocker arm and the fingers, a swiveled block for guiding the fingers, and means for oscillating the rocker arm.

3. The'combination in a feed mechanism for a header, of fingers adapted to receive a blank, a rocker arm, a pivotal connection between the rocker arm and the fingers, a block for guidin the fingers, a rotary suport for said bloc and mechanism for oscilatin the rocker arm.

4. ie combination in a feed mechanism for a header, of spring fingers adapted to rcceive a blank, a block to which said spring fingers are connected, a rocker arm, a plvotal connection between said block and rocker arm, a rod connected with the finger block, a guiding block in which the rod has a longitudinal movement, a rotarysupport forsaid guiding block, and mechanism for oscillating the rocker arm 5. In combination ina blank feed mechanism, a rocker arm, mechanism for rocking the arm, a fixed sup ort, fingers adapted to receive a blank, a swivel connection between fingers and the rocker arm, and a swivel connection between the fingers and the fixed support.

6. A feed mechanism for a header, having fingers adapted to receive blanks, an oscillatory support for said fingers, and a rotatory guiding support for said fin rs.

7. A feed mechanism for a headzr having fingers adapted to receive blanks, an oscillatory support, mechanism for oscillating the support, a pivotal connection between the fingers and said support, and means for swinging the fingers on the pivotal connection, as the support is oscillated.
