ATTACHMENT FOR THIMBLES.

Specification of Letters Patent.

Patented Aug. 23, 1910.

Application filed September 29, 1909. Serial No. 520,093.

To all whom 'it may concern:

Be it known that I, JOHN T. OHMAN, a citizen of the United States, residing at Worcester, in the county of IVorcester and State of Massachusetts, have invented a new and useful Attachment for Thimbles, of which the following is a specification.

This invention relates to an attachment for thimbles adapted to cut threads, and to provide for grasping a needle so as to hold it while it is being pulled through the material being operated upon.

The principal objects of the invention are to provide a device of this character in a simple and inexpensive form so that it can be made up to sell at a reasonable price and yet be efficient for the purposes specied; also to provide a construction which can be inovably mounted on the thimble so that as the thimble wears on one side the device can be turned around to a diierent place' thereon; and to provide such construction that the needle holder and thread-cutter can be operated by the manipulation of a single part of the device.

Further objects and advantages of the invention will appear hereinafter.

Reference is to be had to the accompanying drawings, in which- Figure 1 is a side elevation of a thimble showing one form of the invention applied thereto; Fig. 2 is a similar view partly in section with parts removed. Fig. 3 is an elevation at right angles to Fig. 1 with the movable blade removed, and Figs. 4 and 5 are side views at right angles to each other showing a modification.

In the form of the invention shown in the first three figures, the thimble A is provided with an attachment which may be permanently secured to the thimble or removably applied thereto. In this form of the invention this attachment is provided with a base 10 having a shear blade 11 thereon and a projecting jaw 12. This base l0 is shown in the present instance as of U-shape. Between the blade and jaw is a pivot 13 on which is mounted a pivoted member 14 having a jaw 15 adapted to coperate with the jaw 12 and a cutting blade 16 adapted to move down by the side of the blade 11 so as to constitute a threadcutting device. A spring 17 is employed for normally holding the member 14 up so that the blades will be apart and the jaws 12 and 15 will also be separated, being located on the opposite side of the pivot. Between the ends of the member 10 is preferably located a piece of soft metal 18 for receiving the edge of the blade 16 when it goes down too far. Also near the blade 11 is a projection 19 against which the thread will stop so that the thread can be placed in between the jaws without particular regard to its exact position. It will be seen that by pressing on the end 2O of the movable member the jaws are brought together and so are the blades so that only a single motion is necessary for accomplishing either of the above results, thus simplifying the manipulation of the device.

In the form of the invention shown in Figs. 4 and 5 the device is made simpler. In this case the base 21 is provided with an integral sheet metal split ring 22 surrounding a portion of the thimble and fitting frictionally thereon so that the device can be turned to any point around the circumference of the thimble. It is well-known that there are only two or three spots on a thimble that are ordinarily used, consequently if the attachment were applied rigidly to the thimble, the thimble would soon wear out.on one side and its usefulness be much reduced, but with this construction after the thimble has become worn in one spot the attachment can be shifted around and the wearing spots on the thimble will be shifted accordingly. It will be understood that the form shown in Figs. 1, 2 and 3 can be applied by means of a split ring in a similar way. 'Ihe base 21 extends up substantially to the top of the thimble and then bends back at 23. Just below this bend the material is bent inwardly at 24 toward the base. This is to provide a jaw for grasping a needle when the projecting swinging member 25 is moved toward the base. On this swinging member is mounted a blade 26 for thread-cutting purposes adapted to engage the body of the base. In this case the device is made of resilient metal so that it serves as its own spring. Integrally mounted on the base are projections 27 serving as stops for the thread and also for the blade. It will be seen that as in the former case, pressure on a single point will serve to operate both the thread cutter and needle puller, but in this case the construction is simpler and the eX- pense of manufacture is less. In both cases, the movable blade is set normal to the surface of the thimble and it moves directly toward it to cut the thread.

While have illustratedy and describedVH two forms in which the-invention may be embodied, I am aware ythat many modifications can be made therein by any person.

skilled in the art without departing from the scope of the invention as expressed-in integral therewith, Ya blade movably mountebase for cuttingpurposes and lthe ed on said base, and a member carrying the bladeland having an inward; bend mounted to move with the blade toward the base, and `adapted to hold .a needle thereto.

3. As an article of manufacture, an attachment for a` thimble comprising a split ring adapted lto be mountedon a thimble, a base integral therewith and projecting transversely therefrom, an arm integral with said base at the en d opposite, therin and extending backwardly therealong, sai i arm having an inward bend, and a blade beyond the bend, said blade being adapted to enoagelthe engage the base for holding a needle.

, In testimonywhereof I have hereunto set end'v to v my hand, in the presence of two subscribing y witnesses.
