WINDING-KEY HEAD.
SPECIFICATION forming part of Letters Patent No. 708,243, dated September 2, 1902.
Application filed May 1, 1901. Serial No. 58,266. (No model.)
To all whom it may concern.-
Beit known that I, THOMAS W. R. MCCABE, a citizen of the United States of America, residing at Winsted, in the county of Litchfield and State of Connecticut, have invented a certain new and useful Improvement in Devices Sometimes Known Among Clock- Makers as Ring-Heads, of which the following is a description, reference being had to the accompanying drawings, wherein- Figure 1 is a side view of a device embodying said improvement. Fig. 2 is a top view of the part which may be called the head. Fig. 3 is a view in central vertical section of the device which is shown in side view in Fig. 1.
The object of the invention is the production of a device having certain features of novelty and advantage which is used among clock-makers as a ring-head of key-winder, and especially it has reference to means for facilitating and cheapening its construction.
In the accompanying drawings the letter a. denotes that member of the device which may be called the head. It is of a cylindrical exterior and generally has a threaded orifice in the lower end, as seen in Fig. 3. As shown in the drawings, grooves a are arranged on opposite sides of the head, and within these grooves are the mortises o The letter 1) denotes what may be termed a loop. In the case of a ring-head it is usually round, and in the case of a key-winder it is usually of the shape shown in the drawin gs. The ends of the loop are entered in the mortises a and preferably swing thereon as on a center.
These heads are formed on automatic machines, and the objects of the grooves are to control the position in which the heads are fed where the ends of the loops are introduced into the mortises-that is to say, the mortises in all cases have a fixed relation to the grooves, and as the heads are fed down to the loops they are guided by these grooves, so that the mortises always come to the same positions and expedite the fastening of the loops to the heads. A single groove is suffi cient for accomplishing this object; but for the sake of appearance two grooves are preferably used, and the mortises are cut in the bottoms of these grooves. An advantage of this construction is that the grooves lead the ends of the loop to the mortises, and to a degree the sides of the grooves buttress and support the ends of the loop on the two sides which it is most important that they should be buttressed and supported.
I claim as my invention- The cylindrical ring-head reduced in diameter at one end, one or more grooves eX- tending the full length of the larger diameter, and mortises in said grooves, in combination with the loop having its ends entered in said mortises, all substantially as described.
