REVERSE-FEED FOR READING-MACHINES.
Specification of Letters Patent.
Patented May 31, 1910.
Application filed April 28, 1909. Serial No. 492,694.
following is a specification.
This invention relates to a mechanism for feeding metal pieces or blanks to thev die and punch of a heading, re-heading, trimming or similar metal swaging machine. I This feed mechanism is designed to receive the blanks to be headed, re-headed, trimmed, or otherwise shaped, from any ordinary form of delivery mechanism which presents the blanks, one by one, in a vertical position, and it carries the blanks thus received inwardly and downwardly, and at the same time turns them in such manner that they are presented to the die, having the required configuration,
in a horizontal position with their axes in line with the axis of the die opening and upsetting or swaging punch.
The object of this invention is to provide a mechanism for this purpose, which is simple to construct and operate, is verysure in action, and which can be easlly set whenever desired by anyone, so that it will deliver the blanks to the die with great accuracy, either end forward, in order that the desired end of the blanks may be operated upon by the punch.
Figure 1 of the accompanying drawings shows a perspective view of'a simple form of header provided with a feed whichembodies this invention. As the heading mechanism forms no part of the present invention, only so much is illustrated as is necessary to a complete understanding of the relation of the feed to the other mechanisms. Fig. 2 shows a perspective view, on larger scale, of'a portion 0 the frame of the machine, the end of a means for presenting the blanks to the feed, and the feed mechanism which takes the blanks presented and delivers them axially in alinement with the die. Fig. 3 shows-a plan, with parts in section, of the feed mechanism. Fig. 4 shows aside .elevation of the'same, ,with the feed fingers vertical position. The course of the blanks as they are-carried bythe fingers from the receiving position, shown in Fig. 4, to the die position, shown in Fig. 5, is indicated. in these figures. Fig. 6 shows a side View of the blank carrying fingers with the rotating mechanism arranged to turn the blanks the other end to, from the way they are turned by the same mechanism arranged as shown in Figs. 3 and 4. Fig. 7 shows a plan, with parts in section, of a modified arrangement of the feeding mechanism. Fig. 8 shows a 'side elevation of this modification.
- The frame 1, of the machine illustrated, near one end supports the transversely extending main shaft 2. This shaft at one end has the ordinary fly wheel 3, and between the sides of the frame has a crank 4:. The
crank is connected by the pitman 5 with a gate 6, which is movable longitudinally on the ways 7 arranged along the insides of the sides of the frame. The gate carries a punch 8, which, when the machine is in operation, is reciprocated toward and from the die 9 mounted in the end of the frame as usual in this class of machines. The die may have any necessary configuration to beveled so as to form an oblique passage 15 between them. On the lower end of .the vertical rocker shaft is a rocker arm 16. This arm is, by a rod .17, connected with a lever 18 ,that' is oscillated. byva' cam 19 on the main shaft. A spring 20 is arranged to draw the rod so as to hold the lever aga nst the periphery'of the cam. This mechanlsm,
at the proper time, swings the yoke, first one way and then the other way, so that its beveled ends pass between the first and second blanks, which are hanging vertically by their heads, at the end of the trough, and force the first outwardly into the fingers of the feed mechanism, and at the same time hold the rest-of the blanks in the trough (Figs. 3, 4).
In he first form of the invention illus-- trated, -spring fingers 21 are fastened to an arm 22 that is attached to the end of a shaft 23. This shaft extends through and is free to be rotated in a block 24 that is pivot: ally mounted on the upper end of a rocker arm 25. This rocker arm projects from a rockershaft- 26, which is provided with a rocker arm 27, that, by a link 28, is connected with a rocker arm 29 on a shaft 30. The shaft 30 has a rocker arm 31, with a roll 32, that lies in the groove 33 of the cam block on the main shaft.
The shaft 23 has a spline groove 34, and splined uponthis shaft is a sleeve 35, fastoned to which is a gear 36. The sleeve 35 extends through and is rotarily held against longitudinal movement by a block 37 that is pivotally mounted at the top of the stand ard 38. In the form shown, the stem 39 of the block 37' passes through the hub 40 of a gear 41, that is held stationary in the top of the standard 38 by a set screw or any other means. The gears 36 and 41 intermesh, and as the gear 41 is stationary, when the shaft 23 is swung up and down the gear 36, which is oscillated with the shaft, is rotated so as to turn the shaft 23 on its longitudinal axis 90 degrees. The direction of rotation of this shaft for 90 degrees depends upon which side of the gear 41 that the gear 36 is located. Vhen the shaft 23 is slid out of the sleeve 35, the gear 36 is free to be turned on the axis 39 of the block 37 so that it may belocated on the right hand side of the gear 41, as shown in Figs. 3 and 4, or on the left hand side of the gear 41, as shown in Fig. 6. After the gear 36 has been located on the proper side to give the desired turn to the shaft 23, that shaft is again passed through the sleeve 35.
When the rocker arm 25 stands vertical, the fingers are presented in front of the end of the trough in position to have the first or lowest blank forced into them by the 0s cillation of the yoke shaped gate 14. After the fingers have received a blank, the rocker arm 25 is swung through on are of 90 degrees, as indicated by the dotted line 42 on Fig. 4. This movement of the rocker arm first carries the fingers practically horizontal with the blank in a vertical position for a short distance, so the blank will clear the end of the trough. The continued movement of the arm then carries the fingers downwardly, the shaft 23 sliding through and being guided by the sleeve 35. As the shaft 23 with the fingers is carried down, the gear 36 rolling around the fixed gear 41, imparts to the shaft a rotation of 90 degrees on its axis. As the rocker arm 25 stops in a nearly horizontal position, the last part of the movement of the shaft and fingers is, for a short distance, practically vertical. This action carries the blank from the vertical position at the end of the trough, shown in Fig. 4,
to the horizontal position in axial alinement with the die, shown in Fig. 5, on the course which is indicated by the dotted line 43, extending from one figure to the other. This organization, which carries the blank from a vertical position to a horizontal position at 90 degrees therefrom, at the same time turns the blank around 90 degrees so that it will aline with the axis of the die opening and punch. As stated, by changing the position of the shaft gear 36 with relation to the fixed gear 41, the blank may be turned 90 degrees in either direction, and thus either end may be presented to the die, depending upon the operation to be performed. The same action can be accomplished in other ways, for instance as shown in Figs. 7 and 8. In those'figures, the shaft 44 provided with the spring fingers 45 which receive the blank 46 from the end of the race-way 47, extends through the sleeve 48 hearing a gear 49 in the same manner as before. The gear 49 is located to mesh with either side of a fixed gear 50, depending upon the direction of ro tation to be given the shaft and spring fingers. In this case, the shaft is oscillated by connecting a rocker arm 51 With the end of the stem 52 of the swivel block 53 that supports the sleeve 48 and the gear 49. The rocker arm may be connected by a rod 54 with any means for rocking it. This mechanism oscillates the shaft and spring fingers through an arc of 90 degrees, and at the same time rotates the shaft on its axis 90 degrees, so that the blanks may be taken from a vertical position and carriedyto a horizontal position, and either end presented to the die.
In order to guide the shaft and give the fingrs'a short retractive movement which is practically horizontal, after they have first received the blank, and a short downward movement which is practically vertical, as
they present the blank to the die, the shaft is provided with a grooved block 55, that is engaged by the segmental track 56, formed on the edge of the rocker 57. This rocker is mounted on a rock shaft 58, and is provided with a rocker arm 59 that may be con nected by a rod 60 with any means for rocking the parts. These mechanisms are so timed that the segmental track draws the fingers and the blank approximately horizontally away from the end of the trough,
just before the fingers are swung down. After the fingers and blank have been swun down, the rocker is again turnedso that the fingers will carry the blank down approximately vertically into accurate alinement with the die opening. By this organization the fingers are given a short reciprocation in their upper position, so that they will move forward and grasp a blank, and then move back so that the blank will clear the runway when the fingers are swung down. It also gives the fingers a short reciprocation when they are in their lowest position, so that the blank will be carried into line with the die opening, and then after the blank is grasped by the die, the,fingers will rise and free themselves from the blank and clear thepunch and other mechanism, before they are swung up.
Vith both of the mechanisms described, the fingers approach the end of the trough,
and after grasping a blank move away with-1 out changing the vertical position of the blank, the purpose being to carry the blank safely out beyond the end of the trough before it is lowered. The mechanism also makes it possible, whether the blank is presented one end or the other to the die, .to
' raise and lower the blank for a short disaxis when theyare swung.
tance adjacent to the die in a practically' horizontal position, in order that the blanks may be properly presented to the die.

A feed mechanism for a header, having fingers adapted to receive a blank, mechanism for swinging the fingers, and mechanism for rotating the fingers on their longitudinal 2.
