Appheation filed January 7, 1922. Serial no. 527,583.

To all whom it may concern: 7

Be it known that I, STANLEY GASPARAITIS,

a citizenofthe United States, and a resident ofthe city of Chicago, in the county of Cook and State of'lllinois, have invented certain new and useful improvements in a Lifting Device; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, and to the numerals of reference marked-thereon, which form a part of this specification.

' This invention relates to devices such as tongs which are used for grasping articles 1:3 to lift them. V

It is an object of this invention to produce a device of this class in which the parts shall be held together by a spring which also acts as a pivot.

It is a further object of this invention to produce a device of the class indicated which may be quicklygand easily disassembled for cleaning and reassembled for use.

It is a further'object of this invention to produce a. device of this class which shall be inexpensive tomanufacture andcan readily be produced in a number of forms,

. Other and further objects of the invention will be apparent from the disclosures in the specification and the accompanying drawings. j

The invention (in a preferred form) is illustrated on the drawings and will be hereinafter more fully described.

On the drawings:

Figure 1 is a side view of a pair of tongs involving this invention. Figure 2 is anedge view of the same, Figure 3 is: a section upon'the line 3-3 of Figure 1. I

ZFigure 4: is an end view looking from. the right in Figures 1 or 2. .Figure 5 is a view showing the application of this invention to a pair of spoon shaped 415 lifting members. v

Figure 6 is a section upon the line 6+6 of Figure 5.

Figure 7 shows the application of themvention to a pair of fork-like pivoted members. 1 7

Figure 8 is an edge, View of the form shown in Figure 7 As shown on the drawings:

The pair of tongs shown in Figures 1 to 3 consists of a pair of members pivoted to- :member comprises a handle and;

and a jaw 3 which is upon the same side of the pivot as the handle 1. The handle 2 is continuous with the jaw 4 upon the same side of the pivot as the handle 2. Thus the members do not cross one another atthe pivot, as is usual in ordinary tongs, scissors and similar instruments.

In the form illustrated in Figures 1 and 2, the handle 2 is shown of considerably greater length than the handle 1. This is in order that the handle 2 may be used to lift objects out of hot water or. other places where the worker does not wish to insert his hands. For example, this tool may be used for lifting clothes out of a clothes boiler.

lVhere the handle 1 and jar 3 merge and where the handle 2 and jaw 4 merge. each of the members is provided. with a fiat surface so that the two members contact over a considerable area, as indicated at 5. As shown at Gin Figure 2, jaws 3 and 4: are narrowed asthis portion 5 is approached, and the handles also may narrow towards this portion.

The two members are fastened together by a wire spring. The central part of this wire spring consists of a straight portion 7 which goes across the tool between the handles 1 and 2 just at the left, as shown in Figure 1, of the flat contacting portion 5. At each side of the tool, the wire spring is coiled as indicated at 8 and 9, the innermost end of these coils being connected to the portion 7 by a straight radial part as shown at 10. From the outer end of the coils o

tangential parts

11 and 12 which extent to the curved surface of the member at a point considerably to the right, as shown in Figures 1 and 2, of the middle of the flat surfaces 5. The ends of the

portions

11 and 12 are bent through a'right angle, and seated upon the curved surfaces of the mem bers which lie opposite the flat surfaces 5, as shown at 13 and 1&1 respectively. A groove is provided in each of the members for the reception of the ends 13 and 1 1. This groove is shown at 15 in Figure 2 where it projects beyond the end of the portion 14.

Preferably also similar grooves are provided to accommodate the portion 7 of the spring. Each of these latter grooves is of a depth less than the radius of the wire of the spring, so that the handles 1 and 2 may fulcrum on the wire 7. Preferably this wire is located beyond the end of the flat sur faces 5 but if desired it may be between these surfaces. When the latter position is used,

straight portion 7 This coil is indicated at 18, andto accommodate it a pair of grooves tact.

the su rfacesj do not contac it but are separated by'the wire as indicated in Figure 6.

This figure shows the aws of the mentbers replaced by two spoon shaped ends 16 and are formed inthe members 1 and Qto the left ofthe flat portion 5. Pref- .erably these grooves are not made deep enough to let thecoil 1.8 into themenibers 1 and 2 so far that the surfaces 5 will con- 21-. Because the coil 18'is of smaller diameter than the coils '8 and 9, the

oblique portions

11 and 12 of the spring are not as steep as in the form shown in Figure 1. Also, if f desired, the

portions

11 and 12 maybe made to slope still less by connecting them to the cross pieces 13 and 1% by means of a portion at right angles to the surface 5. One such portion is shown at 9.2.

Another application of the spring pivot or fastener is shown in Figures? and 8, where the members 1 and Qare integral with theforkrshaped jaws 2-3 and 241. In this form of device, the surface 5 is made to contact asin Figure 1. It is obvious that surfaces out of contact asshown in Figure 5 might be used by inserting a coil like 18 instead of the straight portion 7 of the spring, but if this were done the surfaces 5 would not stay outof contact, since the spring would bring the right hand edges of them into contact. This is because the tips of the jaws do not inthis case form a stop; for, instead of contacting with each other, the tines of one fork pass between the tines of the other fork. as shown at 9.5. Thi may also he seen in Figure 8, where one set, of tines is marked 26 and the other set 27.

In the o eration of this device, when the handles 1 and 2 are pressed toward one another, the parts will pivot about the wire 7 or the coil 18. lVhe n' the handles are released, the elasticity of the spring will bring the parts back to the illustrated position, in which, in the, form shown in Figures 1 and T, the members are stopped by the. contact "of the surfaces 5-. In the forms shown in Figures 1 and 5,- they are stoppedby the contact ofthe ends of the jaws. It will thus be some hat n e rm o n n F g re 7 th previsie is it? as p a e u As a consequence, the spoonshaped' jaws contact only at saidtips, as shown at Thetool shown in Figure glis intended for ,hancllingfclothefs in the'lhot water of a'clothes.
