Patented Feb. 7, 1939 PATENT OFFICE TWO-PIECE BAKELITE GRIP Charles A. Bradley, Penn Township, Allegheny County, Pa., assig'nor to The Aluminum Cooking Utensil Company, New Kensington, Pa., a. corporation of Pennsylvania Application June 10, 1937, Serial No. 147,415

4 Claims.

Insulating grips for cooking utensil handles often are made of non-conducting plastic material by molding. The grips may be one-piece moldings, molded around the handle, or attached thereto by means of rivets or the like. Grips for strap handles, and particularly for curved strap handles such as bails, usually are molded around the handle in a single piece, but sometimes are made in two pieces and riveted to the bail handle.

Ineither case, replacement of the grip when it becomes loosened or broken in use in either very dimcult for the'ordinary purchaser of cooking utensils or entirely beyond his skill. Furthermore, in the riveted structures, the rivet heads are generally at or near the surface of the non-conducting grip, and the rivet shank is in direct contact with the metal ball at the point at which it passes through the bail. The rivet heads heat up in such cases and may burn the hands of the user. It is anobject of my invention to overcome these and other disadvantages in the construction of heat-insulating grips for handles. More particularly, it is an object of my invention to provide an insulating grip that is simple in construction and efficient in operation. Specifically, it is an object of my invention to provide an easily replaceable two-piece insulating grip for strap handles, such as bails, which is affixed to the bail in such manner that the fastening means are completely insulated from the metal of the bail to prevent conduction of heat to the surface of the grip.

Referring now to the drawing in which like reference numerals indicate like parts through the several views:

Fig. l is a view, partially in longitudinal section and partially in elevation, of a two-piece grip made of non-conducting plastic material according to my invention and attached to the bail of a utensil;

Fig. 2 is a longitudinal sectional view of the top member of the two-piece grip;

Fig. 3 is a bottom plan view of the top member illustrated in Fig. 2;

Fig. 4 is a longitudinal sectional view of the Fig. 5 is a top plan view of the bottom member illustrated in Fig. 4;

Fig. 6 is a transverse section taken on the line VI-VI of Fig. 1;

Fig. '7 is a transverse section'taken on the line VIIVII of Fig. 1;

Fig. 8 is a transverse section taken on the line VIII-VIII of Fig. 2;

Fig. 9 is a transverse section taken on the line IX-lX of Fig. 2;

Fig. 10 is a transverse section taken on the line X-X of Fig. 4; and

Fig. 11 is a transverse section taken on the line XIXI of Fig. 4.

The insulating grip of my invention is applicable to any type of cooking utensil handle and is particularly suitable as a grip for bail handles. The drawing accompanying this application shows a preferred form of my invention in which the grip is attached to a suitably apertured bail. It is to be understood that the invention is not limited to the exact form illustrated in the drawing accompanying the'application, the insulating grip. of the invention being susceptible to numerous adaptations which will be manifest to one skilled in the art to which the invention is directed.

In the form shown, the bail or handle is substantially arcuate lengthwise and is also arcuate in transverse section over most of its length, as indicated at 2|], and best shown in Fig. 7, but centrally of the grip location has a portion 2| substantially that in transverse section, as best shown in Fig. 6. An aperture 22 extends through the handle centrally of the grip location, and an aperture 23 extends through the handle adjacent each end of the grip location. Between each aperture 23 and the central aperture 22, another aperture 24 is provided.

The top member 25 of the grip has a central boss 26 having a shoulder and a reduced end portion and hollow bosses 21 adjacent its ends. Between the boss 26 and the bosses 21 are solid bosses 28. An internally screw-threaded insert 29, of brass or the like, is provided in each hollow boss 21, the grip member'25 being molded around the inserts so that the inserts are held positively in place.

The bottom grip member 30 is provided with'a central well 3| surroundedby a raised portion 32.

.The Well 3| is of a size and shape to receive the reduced end portion of the boss 26 on the top member. Thebottom member 30 adjacent each end has a well 33 and a countersunk passage 34 extending through the member 30 into the base of each well '33. The countersunk passage 34 is adapted to register with the threaded insert in the hollow boss 21 of the top member. Between the well 3| and the wells 33, short bosses 35 of the same cross sectional size and shape as, and adapted to "register with, the aforementioned bosses 28 on the top member 25, are provided.

In assembling the grip, the reduced end portion of the boss 28 is inserted through the aperare properly located on the handle, the

bosses

28 and 35 meeting through the apertures 24, and the hollow bosses 21 extending through the apertures 23 into the wells 33. It will be seen that in this position, the portion of the bail surrounding the central aperture 22 is gripped by the shoulder of the boss 26 and by the raised surface 32, and that each passage registers with the threaded insert 29 in a hollow boss 21. A fiat headed screw 36 is inserted through each passage 34 into the screw-threaded insert 29 in the corresponding hollow boss 21. The assembly is completed by tightening the screws 36.

When the ball or handle is not in a constant or uniform arc, the grip members are made correspondingly eccentric. In some instances, this eccentricity is too slight to be apparent immediately to the eye, but in the event that one or both of the members were reversed, a poorly fitting grip would result. In such cases, the grip members may be marked near one end, as by the

front markers

31 and 38, which are provided in the molding of the grip so that reversal of the members in assembling them may be avoided.

By this construction, the handle grip is readily and easily assembled, and comparatively easy to manufacture. The hollow bosses 21 surround the inserts 29 and the shanks of the screws 38, completely insulating them from the ball or handle so that the heads of the screwsdo not become heated.

If a grip becomes worn or broken in use, no special skill is required to remove it and secure another grip in place. It will be seen that the 1 top and bottom members are so formed that they cannot be confused, and that the top member is in the form of a shallow channel, while the bottom member is in the form of a deeper and wider channel receiving the top member, to provide asmooth surface on the grip.

In a handle construction, a bail in the form of a strap having spaced apertures therein, a top grip member formed -of non-conducting material and having a hollow boss in each end extending through an aperture in said strap, an internally screw-threaded insert in each of said hollow bosses, a central solid boss on said top member extending through an aperture in said strap, a bottom grip memberformed of non-conducting material and having a well at each end receiving one of said hollow and defining a passage ture 22 and into the well 3| so that the members through said bottom member, and a central well in said bottom member receiving said central boss on said top member.

I
