4 Claims.

This invention relates to feeding devices in general and in particular to a device for feeding hot billets from a conveyer to a die pot.

One object of the invention is the provision of a feeding device which will move the hot billet from the conveyer and discharge it into the die pot without any danger of injury to workmen; A further object of the invention is the provision of a feeding device equipped with safety supports so arranged as to prevent accidental removal of the hot billet during transfer of the billet from the conveyer'to the die pot.

A still further object of the invention is the provision of a billet feeder equipped with safety devices so arranged as to automatically discharge the billet into the die pot upon striking the die pot.

These and other objects of the invention will be apparent to persons skilled in the art from a'study of the following description and accompanying drawings, in which 7 Figure l is an elevational view of the improved feeding device;

'Fig. 2 is a plan view of the feeding device and associated conveyer and die pot;

Fig. 3 is an endview of the improved feeder as seen from adjacent the die pot;

Fig. 4 is a sectional view taken substantially on line 4-4 of Fig. 1;

Fig. 5 is a sectional viewtaken substantially on line 5-5 of Fig. 3

Fig. 6 is an enlarged sectional view of the improved feeder head, and

Fig. '7 is a plan view of the improved feeder head.

Referring now to the drawings in detail, it will be seen that the press or other machine 2 is mounted in a pit 4 extending below the feeder floor 6. The press or other machine has mounted therein the die pot 8 having the upper lip Ill terminating above the level of the factory floor. Fastened in the pit are a pair of channels l2 joined together at their bottom ends by angles M which are adapted to receive bolts or other means [6 anchoring the channels to the floor of the pit. From one side of the channel form uprights comparatively long channels [8 project and these are braced by angle braces 20 as well as by gusset plates 22 extending continuously past the uprights and forming a brace for short channels 24 projecting from the opposite side of the uprights I2. The free ends of channels 18 have mounted thereon bearing blocks 26 (Fig. 4) adapted to receive roller bearings 28. These bearings support a cross shaft 30 which in turn passes through and supports an eye 32 of a swinging arm 34. As clearly shown,

this swinging 'arm is of general Y formation having one end pivotally mounted upon shaft 30 as just described and another arm shapedto have secured thereto a billet receiving head 36. This billet receiving head is preferably formed of an angle with the apex directed downwardly, thus presenting a V cross section as clearly shown in Fig. 3. The top edges of the V shaped billet receiving head are joined together by an inverted U-shaped strap 38 welded or otherwise secured to the legs of the angle 36. 38 is provided with openings to receive short pins 40 upon which are pivotally mounted links 42. The free ends of the links 42 are provided with cups 44 in which are mounted the ends of a shaft 46 carrying a roller cross. tie d8. Intermediate portions of the links 42 are joined together by an inverted U shaped strap 5% secured to the links by any suitable means such as stud bolts 52. Other intermediate portions of the links '42 areadapted to receive short pins'5 l upon which are pivotally mounted short links 56'. These short links are in turn pivotally connected as at 58 to other short links 60 having their free ends pivotally mounted as at 62 on angle brackets 64 welded or otherwise secured to the angle form feeder head. The pivotal connection 58 is preferably extended and has mounted thereon rollers 66, which rollers are adapted to strike and move along the upper edge In of the die pot as clearly shown in line and dash of Fig. 1.

The third leg of the generally Y shaped arm 34 is pivotally connected as at 10 to the upper end of a piston l2 sliding in cylinder 14 under action of fluid pressure fed through pipes 16 (Fig. 1). The lower end of the cylinder M is pivotally mounted upon a shaft 18 carried by the upright channels i2 and by spacing blocks 8 (Figs. 3 and 5) welded or otherwise secured to the channels. Thus it will be seen that actuation of the piston will cause swinging of the arm 34 around its pivot shaft 30. The uprights l2 are held in position by their bottom connection as well as by a pit wall brace 82 (Fig. 1) and by connection of short channels 24 to the conveyer structure 84 which in turn is supported on and connected to the factory floor. Th conveyer may be of any desired form but is preferably of the roller type in which the billet B, indicated by line and dash in Fig. 1, is pushed into position in the feeder head by a pusher P, also indicated by line and dash.

The strap In operation the parts will normally be in their full line position shown in Fig. 1, with the feeder head in substantially horizontal position and the links in the position shown with the cross tie roller 48 blocking the end of the feeder head. With the parts in this position the pusher P will feed a billet B into the feeder head which, together with strap 38, will substantially en circle the billet. Application of power to the cylinder will cause swinging of the arm 34 to the line and dash positions of Fig. 1. During this swinging the strap 38 will prevent the billet being thrown out of the feeder head, while roller cross tie 48 will prevent the sliding of the billet out of the feeder head in a lengthwise direction. When the feeder head has reached a-substantially vertical position the rollers 66 will strike upon the upper edge of the die pot and force the pivotal connection of links 56 and 60 upward, thereby moving the links and causing the pivot connections 54 and 62 to spread. Separation of these pivotal connecting points will swing links 42 about their pivots 4D and move the roller cross tie 48 out of contact with the end of the billet. As soon as the roller cross tie 48 clears the end of the billet it may immediately fall I vertically into the die pot. Motive power may then be fed to the cylinder and the swinging arm with its billet receiving head returned from the line and dash position of Fig. l to the full line position in which it is ready to receive another billet. During return of the arm the links and connecting strap 50 will by gravity return to their billet blocking position as shown in Figs. 1 and 6. While the invention has been described more or less in detail, it will be obvious to persons skilled in the art that various modifications and rearrangements of parts other than those shown and described may be made and all such modifications and rearrangements of parts are contemplated as will fall within the scope of the appended claims defining our invention.
