Application July 10, 1946,v Serial No. 682,697

This invention relates to detachable handles, and .particularly the type to be used for handling hot receptacles.

In my previous patent, No. 2,140,165, issued December 13, 1938, I disclose a device of the same general type, and the present invention is an improvement thereover.

In general, the device consists of an elongated handle member with a slidable member on the handle member. Each yof the two members has two depending hooks inter-cooperating to engage a hot receptacle. As the slidable member is slid along the handle member, the respective hooks are slid toward or away from the cooperating hooks, providing an adjustability for accommodating various sizes of receptacles. A lever and cam device is pivoted on the slidable member, and a spring biases the lever so that the cam engages the handle member, thereby locking the two members in fixed relative positions. When the user wishes to slide the slidable member, he depresses the lever, releasing the cam from its holding position, slides the slidable member, and then releases the lever, whereby the slidable member becomes locked in position.

A n object of the present invention is to `provide an improved device of this general class, which is almost entirely made of simple stampings.

n rThe handle member and the slidable member I are each formed of rounded channel, comparable in cross-sectional contour so that they fit together well. These members can be formed by simple stampings.

The depending hooks on each member can [be formed in the same operations in which vthe members themselves are formed.. One end of eachA member is slotted fora certain distance longitudinally thereof, and the pieces formed thereby are bent to form the hooks.

The lever and cam device is also formed by a stamping operation, and a simple wire spring is employed to bias the cam normally into position for locking the slidable member.

With these and other advantages in view, my invention consists in the construction, arrangement and combination of the various parts of my device whereby the objects contemplated are at tained as hereinafter more fully set forth, pointed out in my claim, and illustrated in the accom-v panying drawings, in which:

Figure l is a side view of the device applied to a receptacle, parts being shown in section;

1 claim. (C1. 294-34)A main handle member is indicated at I2, the slidable member at I4, and the lever and cam device at I6. The main handle member is formed from flat sheet metal stock and is stamped vto form thev blank I8 as shown in Fig. 6. In the stamping operation, one end -of the blank is slotted as indicated at 20, forming two legs 22 and a small projection 24 at the opposite end. The main :body portion of the blank I8 is shaped to semi-circular form in cross-section as shown in Fig. 3. Also, the legs 22 are bent laterally from the main body portion, and at the ends, hooks 26 are formed for engaging under the bead 'or marginal edge 28 of a receptacle 30. The projection 24 at the opposite end of the blank I8 is bentvdownwardly as shown in Fig. l for forming a stop.

The slidable member. I4 is of semi-.circularv cross-'sectional shape, similar to that of the main handle member. Fig. 7 .shows a blank stamped fr omilat sheet metal, before it has been shaped into the finished slidable member.- The vblank of the slidable member vI4 lis-forx'ned witha-main body portion. 32, oneI end of. which-is .slotted-at 34,"forming legs 36. AAt'the same endofithe blank on which the legsv 3B are formed, are a pair of oppositely extending lateral,` ears 38, having holes punched therein. At the' far or opposite end are another pair of projections, constituting oppositely extending lateral lugs 42. Formed on one side of the'blank, adjacent the corresponding ear 38, is a lug 4I having a hole 43. The blank as thus cut, and as Shown in Fig. 7, is shaped into the ni'shed, lsemi-circular cross-sectional shape for assembling in thedevice. The curvature of the two members is similar for providing a cooperating sliding fit. The leg `portions 36 are bent laterally from the main body portion 32, and the ends are bent back to form hooks 44, which are adapted to engage the receptacle 30 similarly to the hooks 26.

AThe ears 38 are bent inwardly, as shown at 4'5, and upwardly (Fig. 4), to a position where the holes 40 are in alignment and adapted' for pivot ioreng'aging different-'sized receptacles 3Il` ally supporting the lever and cam device IB. The laterally extending portions 45 of the ears 38 secure the slidable member I4 on the main handle member I2. The lugs 42 on the opposite end of the main body portion 32 are bent inwardly toward each other, as shown in Fig. 5, and positioned on the open side of the main handle member. The ears 38, and the lugs 42 together retain the slidable member I4 on the main handle meinber I2 and keep it alignment thereon. The lug 4I is also bent inwardly to form a point of reaction for a spring which will be described later.

The lever and cam device I6 is formed .from a blank as shown in Fig. 8. The blank, similarly to the other parts of the device, is formed from 1 flat metal stock. The blank has a bodyv portion 4B having opposite laterally extending extensions 48 which ultimately form cam means. Inwardly from the lateral extremitiesA of` the cams 48 are holes 5D, one associated with each extension 48EV Themain body portion 4S' tapers from the lateral extensions 48 to the `opposite end.' The blank` isf then shaped into a rectangular'. cross-sectional shape' asshown in Fig. 4- so thatthe holes 505 are in alignment.' When thus springv is of a common wellknown type having a coiledportion 56'and legs 518'. The pin 52 ex'- tends through the coiled-portion 56 of the spring and thelegsI 58 extend in thev direction of the lever I6, one leg havinga downwardly extending tip 59i which is inserted in the hole 43 inthe lug 4I'I; and the other leg contactingy the inner side of the channel forming the lever I6.

The cam'means49 is' so shaped that-when the' lever I6 is biased upwardly byv thev springf'fl; it

comes intoicontactf with the main handle member" I2', and when the lever I6 isdepressedV by the user, the cam means 49 comes out of con-v tact withthe main handle memberA |21' VBy depressingtlei leverv I6, the s'lidable m'en'iber-` I4 can bevslidalongv the handle member I2v for adjust'-` ing the legs 22'arid 36`with relation `toeaclfiother willfbe'noted that'tlieY springs 54' does notco-me intot direct contactwiththe'main handlez memberv I2,"` but'is supported by the slidable. member. I4. Thus the `slidable member` can vbeeasily slid' 4 on the handle member without any dragging effect by the spring. The downturned lug 24 prevents the slidable member I4 from being withdrawn from the handle member I2.

From the foregoing it will be noted that the device is very simple and inexpensive to manufacture, and makes a pleasant appearing product. The curvature of the channel forming the handle member I2, gives it great strength for handling heavy receptacles.l

Although I have herein shown and described a preferred embodiment of my invention, manifestly it is capable of modiiication and rearrangement of'y parts without departing from the spirit and scope thereof. I do not, therefore, wish to be understood as limiting this invention to the precise form herein disclosed, except as I may be so limitedby the appended claim.

I claim as -my invention:
