6 Claims. 1

This invention has to do with so-called collar attachments, or that class of devices used on a shirt collar for maintaining the points thereof in close proximity to a shirt bosom.

An object of the present invention is to provide a simple but Wholly effective form of attachment wherein two spiral lineally extending springs are employed, one lying within the other, terminals of which are adapted to act in opposite directions to jointly engage a collar point while the springs lie in the fold of the collar, the natural tendency of stress causing the collar points to hold close to the shirt bosom.

Another object is to provide a pair of spiral springs housed one within the other, together with an enclosing member for two adjacent terminals of the springs, one of said terminals being fixed with respect to said member while the other is shiftable with respect to both the fixed named terminal and said member whereby such terminals may be made to separately impale the collar point during stresses set up on the two springs in the application of the device to the collar.

The advantages of the structure will appear from the following description aided by the appended drawing forming part thereof.

Figure l of said drawing is a front elevation of the collar of a shirt showing a device of the present invention in place at each collar point.

Figures 2 and '3 are plans of the two opposite sides of the collar attachment shown full size.

Figure 4 illustrates in perspective, and much enlarged, an enclosin member showing two spring terminals project ng therefrom.

Figure 5 is a longitudinal section of the member shown in Figure 4 produced on line 5-5 of Figure '3.

Figure 6 shows in perspective a portion of ,one of the coil springs illustrated Figure 5,

Figure 7 is a longitudinal section of part of the member shown in Figure 5 to illustrate certain perforations in the wall thereof, and being pro.- duced on the same line 5.--5 as in Figure 5.

Figure 8 is an end elevation of the member shown in Figures 4 and 5.

Figure 9 is a transverse section of the member of Figure 5 produced on line 9-@ thereof, and

Figure 10 is identical with Figure 5 but shows both springs therein under stress as compared with said Figure 5.

The structure in the present form of collar attachment is unique in that two spiral springs are provided, one of which lies within the other, and serve, as their purpose, to bring about the control of the point of a collar without the usual complication in construction and operation.

In Figure l one of the devices is shown applied to each of the points of a collar identifiedat A. The structure is best shown in Figures 2 and 3 wherein the simplicity of appearance is evident. The device includes a spring l within which is a spring 2 of an outer diameter slightly less than the inner diameter of said spring I, thus permitting the convolutions of both to freely move with respect to each other. The joint springs are of lengths suilicient to extend from near the extremes of the cellar point in an angling direction upwardly to lie for a considerable part within the fold of the collar and paralleling said fold as in said Figure 1, the opposite extremities of the springs each terminating in this instance in a cavited member 3 shown in Figure l and some of the figures following.

As in Figure 5, for example, the said member 3 is, in this instance, a relatively long and narrow shell somewhat flattened so that a flat side thereof may face a collar point while its counterpart may lie between the spaced collar portions at the said collar fold.

One end of the member receives against it an end of the outer spring 5, the latter being soldered or otherwise fixed to said member, while the extremity of said spring denoted at 4 extends into the cavity of said member and thence projecting from a side wall of the same, and sharpened to create an impalement point facing toward the opposite end of such member.

The end of the inner spring 2 extends into the cavity of the member and terminates in a hooked and sharpened impalement point 5 which extends toward and opposes the point ,4 while lying substantially in the same plane therewith.

Said spring 2 is free to stress within and with respect to the member 3 but is normally prevented doing so since normally its hook 5 lies against an abutment 6 of said member. That is to say, as shown in Figures 5, 8 and '10 the outer or free extremity of the member 3 is provided with a slot 1 central thereof acting as a guide for, and supporting the hook 5 in an upright position, the wall of the member at the terminus of the slot providing said abutment, it being observed that the slot of such extent that the hook it may have movement away from the abutment in stretching the spring of which it is a part.

Normally the convolutions of the outer spring I are in abutment with each other and since the members 3 are affixed to the ends thereof they can be no closer to each other than the total length of the unexpanded spring. The inner spring, in efiect, is attached at one end to the member but when unsprung is shorter than the spring I. When attached to both members 3, however, it is under stress or pull and is longer than the spring I as held by said members.

It is found that when the wire of Said outer spring i of a type that is less stifi than the inner one said spring may be easily and freely and even abruptly bent laterally, yet maintain considerable stiffness when in its normal straight line position. The relation of the springs, therefore readily serve the purpose required herein, especially when the constantly stressed spring 2 maintains a permanent pull upon the members 3 which tends to draw the latter toward each other, which action keeps the said convolutions of said spring in their abutting relation.

It is preferred to attach a member 3 to each end of the spring structure since thereby either end of the device may be used at the time it is to be applied to the collar. But it is to be understood that but one of said members may be employed since these ends of the springs where a member 3 is lacking could be connected to each other and thus serve as though said member were present.

In either form, however, the manner of attachment as well as the action of the device is as follows: One extremity of the structure is pushed up snugly into the fold of the collar, the end having a member 3 depending toward, or being brought down to the collar point whereat the said member is grasped and the hooked point made to impale the said collar point by first drawing upon the spring 2 to increase the stress thereon. Upon pressing the collar point and the member 3 together the hook will engage the collar point material. This resulting, the pull of said spring will shift the member toward the impalement point 4 a sufficient distance to cause that point also to engage the fabric of said collar point. Thus, both points i and 5 are jointly in service with the result that the collar point is firmly and positively held in respect to the said member 3. Since that part or the spring structure that lies in the collar fold is frictionally held securely by the collar portions any necessary pull upon the spring 2 may be readily made and, conversely, the reaction of the spring in its pull upon the collar point is likewise sustained. Naturally, the effort of the combined springs to straighten, or take up a straight line, results in the collar point being drawn toward and against the shirt bosom as the requirement.

Although the hook 5 may meet the abutment 6 in the pull of the spring 2 it is free to back away therefrom when under strain on occasion or before engagement as in the collar point.

While the member 3 has been described and shown as of certain detailed construction it is understood that any other form and arrangement, and answering in substantially the same, may be employed.
