G. A. CARLSON THIMBLE Filed April 10 1950 Patented Mar. 8, 1932 warren STATES PATENT oFFICEw GUSTAV A. CARIISON, OF CHICAGO, ILLINOIS, ASSIGNOB TO THE BOYE NEEDLECOM- I'ANY, OF CHICAGO, ILLINOIS, A CORPORATION OF ILLINOIS THIMBLE Application filed. April 10,

This invention relates to thimbles, and more particularly to a thimble equipped with means for engaging and severing threads.

One of the objects of the invention is to provide a thimble of simple and inexpensive construction which is equipped with means for receiving and severing threads. A further object is to provide a thimble with severing segments which are adapted to readlly engage thread and grip it so that it may be broken with little effort. Another object 1s to provide a thimble with thread severing means and guards which serve to hold the thread out of engagement with the severing means while at the same time permitting the thread to be readily drawn into engagement with the severing means when desired, Other objects and advantages will appear as the specification proceeds.

The invention is fully described in the following specification and shown in the accompanying drawings, in which-- Figure 1 is a perspective view of a thimble embodying my invention; and V Fig. 2 is a broken sectional view, the section being taken as indicated at line 2 of Figure 1.

In the illustration given, A designates a thimble which may be of the usual shape an construction. The thimble is preferably provided with a finger guard piece 1 which is provided with a roughened surface or indentations 2. The open end of the thimble is preferably equipped with a rim 3.

The thread severing means comprise the extruded segments't which are preferably formed in adjacent relation, as shown very clearly in Figure 2. Each of the segments 4; is turned so as to form with the wall of the thimble a central loop section 5 adapted to receive a thread and a lower wedge or V-sec; tion adapted to grip'the thread when it is drawn thereinto. At the \l-point 6 the thimble wall and the adjacent segment wall present sharp edges which are adapted to sever the thread when the thread is drawn therein.

By arranging the pair of segments 4 so that the openings? of each segment face each other, the rounded outer surface of the segments serve as guards which prevent the 1938. Serial .110. {143,170.

In the operation of the device, the thread i is drawn through the opening 7 of one of the segments the thread. The thimble may be then moved along the thread until the exact point of severance 1s reached, at which time the thread i is drawn toward the V-point 6. Here the thread is firmly gripped between the wall of the thimble and the segment 4 and the cutting edges of the two elements tend to sever the thread. A slight pull on the thimble or the thread causes the thread to part at the point of engagement with the segment 4:.

While one segment 4- may be used, it is preferred to use two segments, as illustrated in Figures 1 and 2, so that each of the seg ments provides a guard, as well as a finder for the other segment. Also, with this construction the thread may be severed by pulling it toward either of the segments.

The severing means are simple and may d be formed from the metal of the thimble wall at slight expense. Such means enable the user to dispense with scissors or other cutting means and provide a very convenient and speedy method of cutting threads.

The foregoing detailed description has been given for clearness of understanding only and no unnecessary limitations should be understood'therefrom, but the appended claims should be construed as broadly as permissible in view of the prior art.

I claim:

1. A thimble comprising a hollow body having an open upper end and adjacent thereto a pair of vertically aligned outwardly-struck curved thread-severing members mutually guarding each other, the members being severed from the wall of said body except at the upper end of the upper member and the lower end of the lower member, said 4 so that the loop portion 5 receives members having outward bulges and in- I curved free extremities.

2. A thimble as specified in claim 1, in which said wall has an intact portion be tween and slightly back of the free extremities of said members.

3. A thimble having integrally opposed tongues struck outwardly from its wall to form outwardly bulged thread-engaging elements, the free extremities of said elements being curved inwardly and spaced a slight distance apart, said elements serving to mutually guard each other and tending to prevent accidental catching of the thread in either of said elements.

In testimony whereof I hereunto set my hand this 8th day of April, 1930.

GUSTAV A. CARLSON.
