1 Claim.

This invention relates to a storage device for type metal feeder ingots.

It is anobject of the present invention to provide a combined type metal feeder ingot storage device andconveyor for storing ingots from the time they are made to the time they are taken to the typesetting or typecasting machines wherein provision is made for automatically stopping and locking the storage platform at a predetermined point, and wherein the platform can be lifted from the supporting bearings to permit access to the space beneath the platform and to facilitate the cleaning of the top of the platform.

Other objects of the present invention are to provide a storage machine for type metal ingots, which is of simple construction, inexpensive to manufacture and efficient in operation.

For other objects, and for a better understand-. ing of the invention, reference may be had to the following detailed description taken in connection with the accompanying drawing, in which Fig. 1 is a top plan view of the storage device and of the lifting mechanism.

Fig. 2 is a cross-sectional view taken through the storage device and illustrating the operation of the lifting mechanism.

Fig. 3 is a detailed fragmentary view showing the hinge which is connected to the table to lift the same from its bearing supports.

Fig. 4 is a fragmentary and cross-sectional view taken through the table plate and looking in elevation upon the stop device for retaining the table against rotation.

Fig. 5 is a cross-sectional view taken through the spring stop for the table.

Fig. 6 is an end elevational view of the spring stop.

Fig. '7 is a cross-sectional view of the spring stop taken on line 1-1 of Fig. 5 and looking in the direction of the arrows thereof.

Fig. 8 is a side elevational view of the spring stop device showing the location of the stop pin at two'different positions thereof.

Fig. 9 is a top plan view of a modified form of the invention.

Fig. 10 is a cross-sectional view taken on line Ill-l0 of Fig. 9 and looking in the direction of the arrows thereof.

Fig. 11 is a side elevational view of the storage device.

Fig. 12 is a top plan view of the ball bearing the arrows thereof.

Fig. 13 is a bottom plan view of the member on 2 the storage device adapted to cooperate with the bearing support shown in-Fig. 12.

Referring now particularly to Figs. 1 to 8, 2| represents a supportingbase for a rotatable storage carrier 22 having a central upstanding tube 23 for storing metal and the platform lifting mechanism when this mechanism is not in use. The supporting base 2| has an annular portion 24 with a groove 25 therein for ball bearings 26 extending into a groove 21 of a ring 28 fixed to the bottom face of the carrier 22. A skirt is secured to the outer periphery of the ring 28 and extends downwardly over the portion 24 to retain the carrier againstlateral displacement on its support 2| and to act as a shield against dirt.

At spaced points on the platform of the carrier are holes 30 into which banking pins 3| may be placed. When the platform is revolving a pin so placed will strike a banking block 32 bringing the platform to a halt. This will happen when the pin illustrated in Fig. 4 is down all the way in the hole as shown in dotted lines, a substantial portion of it extending below the platform. However, the pin 3| may be held up by a spring 33 under the pins head 35 to such a height that only a small portion of the pin extends below the platform. The upper edge at either end of the banking block, will engage the beveled end 34 of the pin, as the platform rotates, and raise the pin slightly. This releases the spring 33 which snaps back to its normal position indicated by the dotted lines. The pin, left without support, will ride atop the banking block to the other end where it will fall to its lowest position. If another pin be placed all the way in the hole immediately behind this pin, the pin behind will strike the banking block at the rear end just as the pin in front falls at the front end to its lowest position. The platform will thus be halted and locked. The upper end of the spring 33, when the pin is raised, engages witha knurled flange 35 above which is a knurled liftinghandle 33.

The spring deviceor-hanking block 32 comprises a channel member or outer casing 38 having open ends 39 bent inwardly to retain telescoping spring containers 4| and 42 housing a spring 43. The top of the casing 38 is open as indicated at 44 and through this opening bankingpin 3| may pass until it is restrained by the action of the cushioning spring 43 acting within the container parts 41 and 42.

On the carrier 22., ipes 45 are extended outwardly from the center tube 23 and are supported at their outer ends-by, posts 43 extending upwardly from the carrier platform. Extending through the posts 46 is an annular rail 41 formed in sections coupled with one another. Other rails can be extended through openings 48 in the pipes 45. These rails and pipes are arranged to support the pigs in an upright position upon the carrier.

In order that the carrier platform can be tilted upwardly at times in order to gain access to the thrust bearings on the support 2|, there is provided atone sideof the support 2!, an upstanding portion" 49 to which there is hinged a plate as by means of a hinge pin 52. This plate 5| can be made secure to the carrier platform at these times by screws 63. The platform will then be hinged upon the pin 52 to assume a dotted line position as shown in Fig. 2. A weight 54 is secured as indicated at 55 to the upper end of a post 46 to assist in the upward movement of the carriage. While in the raised position, the

carriage will be supportedby a rod 66 fitted under the carriage and extended into an opening 51 in the support 21 and against a spring 58 lying within the opening. The rod 56 will be threaded in hole 61 in the platform 22.

Referring now particularly to Figs. 9 to 13, there is shown a modified form of the storage device wherein the support is of less diameter than the support of the previously described form of the invention. This support is indicated at 62 and is provided with a round top portion 63 in which there is a groove 64 for ball bearings 65. There is a support member 66 which is attached to carriage platform 61 by means of bolts 68. This support 66 has a projection 66 which extends through an opening H in the center of the support 62 to prevent. tilting the platform 6'! on support 62 and to prevent lateral displacement of the platform. A plate 12 and screw 73 fixes the projection within the opening it. The support member 66 has a complementary groove for receiving the ball bearings 65 and also a ring I4 which extends down over the round portion; 63 0fthe support 62 to shield the bearing from dirt.

Attached to the support 62 and extending radially therefrom is an arm 1! having an upstanding support 78 to which a plate 79 can be hinged by a pin 8! for the purpose of connecting the plate to the platform 61 to cause the same to be elevated from the support 62 at times when access is desired to oil the bearings. On the plate 19 there is fitted an upstanding member 82 having a hinge joint 83 with an arm 84 with a weight 85 thereon. By the use of this weight 85 and the arm 84 the platform can be easily and readily raised from the support.

The platform has the pins 3! for engaging with spring device 32 which is located upon the radially extending arm 71 of the support.

Radiating from the center of the platform are 4 a plurality of strong partitions 81 between which there are disposed openings 88 for receiving pigs 89.

While various changes may be made in the detail construction, it shall be understood that such changes shall be within the spirit and scope of the present invention as defined by the appended claim.

I claim:

An ingot holder comprising a supporting base, a platform journaled on said base and positioned to rotate in a horizontal plane thereon, supporting elements for carrying pigs positioned on said platform, a banking block having open slots in the ends mounted on said base, telescoping members positioned in said banking block, a spring in the telescoping members of the banking block for urging the telescoping members toward the ends of the block, said platform having spaced radially disposed holes therethrough and said holes positionedto correspond with the slots in the end of the block, pins withbeveled lower ends and having heads on the upper ends adapted to be positioned in said holes of the platform, and spring fingers mounted adjacent said holes and adapted to extend inwardly under the heads of pins positioned in the holes, said spring fingers retained in position under the heads of the pins by the weightof the pins whereby upon engagement of the beveled lower ends of the pins with the upper edges of the ends of the banking block the pins are elevated and ride over the upper surface of the banking block thereby releasing the spring fingers so that upon reaching the far end of the block the pins drop to co-act with a following pin dropped through the next hole of the platform by hand for arresting and locking said platform.
