SUPPORT AND TURNING RIGGING.

Specification of Letters Patent.

Patented Oct; 22, 1918.

Application filed. June 14, 1918. Serial No. 240,015.

To all whom it may concern:

Be it known that I, GUSTAF P. NVERN, a citizen of the United States, residing in the city, county, and State of New York,.U. S. A., have invented certain new and useful Improvements in Support and Turning Rigging, of which the following is a specification.

This invention relates to a support and turning rigging primarily designed for manipulating large ingots or the like when being worked upon by a power hammer, press or anvil.

The invention has for a general object to provide a novel construction for a device of this class which will be of much more compact form, particularly as to vertical dimensions, than those now in use, thus permitting its use in places having restricted head room.

A further object is to provide a rigging of increased strength and rigidity with its operating parts protected or inclosed.

For further comprehension of the invention and of the objects and advantages thereof, reference will be had to the following description and accompanying drawings and to the appended claims in which the various novel features of the invention are more particularly set forth.

Figure 1 of the drawings is a face view, partly broken away, of my improved sup port and turning rigging.

Fig. 2 is a side view of the same, also partly broken away.

Fig. 3 is a horizontal section on the line 3-3 of Fig. 1.

Fig. 4 is a plan view of the suspension yoke.

The frame of my improved turning rigging comprises a pair of side plates 2 and 3 rigidly secured together by the bolts 4.

A shaft 5 is mounted in this frame and carries a winding drum 6 having a large gear 7 formed integral therewith. This gear meshes with a pinion 8 mounted on a shaft 9 also extending between the side plates, near the top thereof. This pinion has rigidly secured thereto a worm gear 10 also on the shaft 9 and meshing with a worm pinion 11 fixed on a horizontal shaft 12 extending parallel to the side plates 2 and 3. The gear 10 and pinion 11 are mounted in a housing 13 having saddle extensions 14 which are fixed on the inwardly projecting angle irons 16 extending for a distance along the top edges of the side plates 2 and 3.

Thisshaft 12 is driven by a motor 17 of any suitable type supported by a second pair of angle irons 18 carried by the top edges of the side plates. It will be obvious that when the motor is operated the drum 6 will be rotated at a reduced rate of speed. I do'not claim any novelty in the means here shown for driving the drum, since such means is common in turning riggings.

According to my invention a pair of.

spring holding castings or forgings 25 and 26 are carried respectively by the side plates 2 and 3. As shown clearly in the drawings, these castings are each in the form of a double U which extend up the sides of the respective plates, with the legs turned toward the plate as shown. With this arrangement each of these spring holding members 25 and 26 forms, in conjunction with the respective side plates 2 and 3 a pair of vertical sockets 27 and 28 which contain the springs 39 and 39 upon which the frame is suspended. These members 25 and 26 maybe secured to the side plates 2 and 3 in any suitable manner, being here shown as provided with integral flanges 29 and 30 riveted, as at 31. to the plates.

The upper ends of these members 25 and 26 above the sockets are filled in, as indicated at 32 in Fig. 2, to provide abutments for the upper ends of the springs.

These parts are all suspended from a yoke 35 by means of a series of rods arranged in two pairs 36 and 37 respectively, which extend down along the plates 2 and 3, passing through suitable openings in the upper portions 32 of the members 25 and 26, and carrying compression springs upon their lower ends. As here shown, the supporting springs, forming cushioning devices, are each composed of two springs, as shown at 38 and 39 in. Fig. 2, on each rod, separated by a washer 40, the lower spring resting on a washer 41 secured on the lower end of the rod 36 by nuts 42. WVhile I have shown only one of the spring sockets with its rod and springs, in detail elevation it is to be understood that all four sets are alike in construction and arrangement. The rods 36-37 may be secured to the yoke by being passed through suitable openings 43 in the yoke 35 and secured to the latter by the nuts 44. The yoke 35 is provided with a suitable eye 45 to receive the hook of a crane or the like.

The lower ends of the spring sockets 25 and 26 are sheared ofi in a downwardly and The use and operation ofdevices of this nature is Well understood and it 1s notthoughtrnecessary to give any further de scription of the operation thereof, which will be obvious from its Construction.

It will be apparent that I have provided a support and turning rigging of a compact construction having aminimum vertical dimension and which is also of great strength and rigidity. parts are protected from damage and the supporting springs may be readily adjustedto secure even tension without dismounting any of the parts of therigging.

Whatv I claiin' is l. A, device of the class described com prising a;yoke, a series of rods depending from said yoke, a frame located between the lower portions of said rods, a drum mounted on said frame, and cushioning devices carried by said rods and having the upper por tion ofsaid it'rame restingthereon.
