MEANS FOR HANDLING SHELLS.

Specification of Letters Patent.

Patented May 8, i949.

Application filed November 2, 1918. Serial No. 260,810.

To all whom t may concern Be it known that I, JOSEPH FULLMER SCHOTT, a citizen of the United States, re-

siding in Philadelphia, Pennsylvania, have4 invented certain Improvements in Means for Handling Shells, of which the following is a speciiication.

My invention relates to certain improvements in hoists for handling shells which are in the process of being filled.

The object of the invention is to provide means for quickly handling large shells and transferring them from one table to another and from a vertical position to a horizontal position and vice versa.

While the invention is especially applicable for handling shells in a gas filling plant, it will be understood that the invention can be used for handling other than gas shells and can also be used for handling any object of a shape that can be grasped by the gripping means.

. In the accompanying drawings:

Figure 1 is a side view in elevation illustrating my improved shell handling machine and showing the shell in the vertical position Fig. 2 is a front elevation, the shell being omitted;

Fig. 3 is a side view of the lower portion of the machine, showing the shell in a hori- Zontal position;

Fig. 4 is a rear view looking in the direction of the arrow, Fig. 3;

Fig. 5 is an enlarged plan view of the gripping means for holding the shell, and

Fig. G is a view illustrating the depending frame mounted to turn on the trolley.

1, 1 are two overhead beams on which are mounted rails 2. 3 is a trolley having flanged wheels 4 mounted on axles 5, 5% These wheels are arranged to travel on the tracks 2. The axle 5 is extended, as shown in Fig. 3, and on the end of the axle is a grooved chain wheel 6 around which passes a chain 7 so that on pulling the chain on one side of the wheel the trolley is moved in one direction and on pulling the chain on the opposite side of the wheel the trolley is moved in the opposite direction.

8, 8 are two depending frames in the forni of channel irons and, in the present instance, there are two channel irons on each side. These channel irons are spaced apart to form a guideway 9 for the cross head 10, which has a portion 11 extending` into the guideways 9. Attached to this cross head is a piston rod 12 which passes through a stu'lling boX 13 in a cylinder 14 mounted on the trolley 3 and on the upper end of the piston rod is a piston within the cylinder. The cross head has an extension 15 which is forked and has bearing 16 at its lower end. Mounted in the bearings is a shaft 17 on which is mounted a pivoted frame 18. On each end of the shaft is an arm 19. The frame 18 carries the gripping jaws which grasp the shell a', as clearly shown in Fig 1. The arms 19 are connected to the forked head 20 attached to a piston rod 21 which extends into a cylinder 22 and has the usual head. The gripping jaws are pivoted to the frame 18 at 23 and each jaw 24 has a curved section 25 shaped to engage the body of the shell and preferably lined, as at 25, with material similar to the ordinary brake lining. Each jaw has a rearwardly extending arm 26. A cylinder 27 is pivoted at 28 to one jaw, while a rod 29 is pivoted at 80 to the other jaw. The rod eX- tends into the cylinder and has a piston on its end adapted to the cylinder. 31 is a supply pipe communicating with the inner end of the cylinder. The several cylinders are connected by pipes with any suitable pressure mechanism, pneumatic, hydraulic, or steam, so that by operating the valves in the ordinary manner the mechanism can be controlled.

The operation of the machine is as follows I will describe the invention as used linl handling shells in a gas filling plant. These shells are arranged in a vertical position on a table, or on a car, and are filled with liquid in the ordinary manner. The upper end of the shell is closed. It is the usual practice, after the shells are filled with liquid to lay each shell on its side, as illustrated in Fig. 3,

.so as to detect any leakage at the filling opening. The shell is then removed from the lilling station. This is generally accomplished by hand with small shells, but with larger shells it is impossable to handle them quickly and carefully by hand. The shells must be handled quickly, as any delay would materially interfere with the output. Therefore, as soon as a shell is filled the jaws of the machine grasp the shell, as indicated in Fig. 1. The valves controlling the piston in the cylinder 14 are then operated so as to raise the cross head 10 with the shell to a given height, then the trolley is moved on its rails so as to bring the shells above a testing table. The valve mechanism for controlling the fluid in the cylinder 22 is operated so as to turn the shell from the vertical position, Fig. l, to the horizontal position, Fig. 2. Then the cross head 1() is lowered so as to lay the shell onto the testing table and the machine is moved to its Iirst position.

While I have shown the machine provided with a single jaw, it will be understood that it can be provided with two or more jaws mounted on a single frame, which is con- -trolled by a single cylinder and piston.

It will also be understood that the location of the different cylinders may be changed without departing from the essential features of the invention. Any suitable means may be used for actuating the several movable devices, as the object is to provide means for grasping the shell andl turning it from one position to another.

In some instances, I may provide means for pivoting the 'handling device on Jthe overhead trolley, as shown in Fig. GQ In this instan-ce, the trolley 8a may have a circular track on which rests a flanged bearing plate 32 carrying the suspended frame 38 and the operating cylinder 14, or, instead of a bearing plate, rollers, or balls, may be used, the idea being to provide a device that will travel not only on the track, but will also be capable of being turned so as to allow a shell to be placed in any position desired.

lVhile the invention is especially adapted for handling shells in gas filling plants, it may be used for handling other shells, particularly those of the larger type, and other objects which have to be quickly and carefully transferred from one point to another.

I claim:

1. The combination in a machine for handling shells and like objects, of an overhead trolley; rails on which the trolley is mounted; a cross head carried by the trolley;

means for raising and lowering the cross head; a frame pivoted at'the lower end of the cross head; means for turning the frame on its pivot; jaws for grasping the shell pivotally mounted on the frame; and means for guiding the jaws so that a shell can be grasped, lift-ed, transferred and turned from a vertical position to a horizontal position.

2. The combination of an overhead rail; a trolley mountedon the rail; depending guides carried by the trolley; a cross head adapted to the guides; a cylinder on the trolley; a piston rod 'connected to the cross head and extending into the cylinder and having a piston therein; a frame pivotally mounted on the lower end of the cross head an arm on the pivot; a piston rod connected to the frame; a cylinder into which the piston rod extends, said cylinder being mounted on the cross head; jaws carried by the frame and arranged to grasp a shell; and means for actuating the jaws.

8. The combination of overhead rails; a trolley mounted on the rails and having depending guides; a cross head adapted to the guides and arranged to move vertically; a cylinder mounted on the trolley; a piston rod secured to the cross head and extending into the piston; said piston rod having a piston therein; bearings on the end of an extension of the cross head; a pivot shaft mounted in the bearings; a frame mounted frame for engaging the means for opening and closing the jaws; an arm on each end of the pivot shaft; a head to which the arms are secured; a piston rod connected to the head; and a cylinder mounted on the cross |head and into which the piston rod extends.

4. The combination of overhead rails; a

Ytrolley mounted on the rails; depending guides; a cross head mounted in the guides; means for raising and lowering the cross head; a frame pivoted to the lower end of the cross head; means for turning the frame on the pivots; a pair of jaws pivotally mounted on the frame and arranged to grasp a. shell; said jaws having rearwardly extending arms; a cylinder pivotally mounted on one arm; a piston rod mounted on the other arm; said rod having a piston adapted to the cylinder so that when the cylinder is under fluid pressure the jaws will be closed and will grasp the shell and when the pressure is released the jaws will be opened, releasing the shell.

5. The combination in apparatus for handling shells, of. an overhead track; a carriage thereon having a turn table; a frame mounted on the Vturn table; means for grasping a shell; means for moving a shell either to the vertical' or to the horizotal position;
