7 Application filed December 5, 1902- Serial No. 133,993. (No model.)

To all'whom it may concern.-

Be it known thatI, GEORGE'W. DOVER, a citizen of the United States, residing at Oranston, in the countyof Providence and State of Rhode Island, have invented certain new and useful Improvements in Pins, of which the following is a specification. 1 My invention relates to brooches and other pins, and has for-its main objects strength, cheapness, and simplicity. These are attained by the improved structure of both the pin-tongue and the housing or joint, as will be hereinafter set forth, and shown in the ac companying drawings, wherein-' Figures 1, 2, 3, 4, 5 are side elevations of the pin-tongue in its various stages of comple-- tiou; Fig. 6,a plan of the housing-blank; Figs. 7, 8, 9, side, edge, and plan views,respectively, of the housing-blank bent into final position. Fig. 10 is a perspective view of a modification of the invention, and Fig. 11 a central longitudinal section of the same.'

Like letters of reference indicate like parts throughout the views. a

The novel pin-tongue is formed from an ordinary pin tongue blank (1, Fig. 1, by swaging the blunt end thereof intoa spherical head I), as shown in Fig. 2. The head is then flattened and centrally pierced c, Fig. 3. A portion of this circular flattened head is cut away to form a peripheral'shoulder or projection d, Fig. 4.. An edge view o'f'the completed tongue is shown in Fig. 5.

Referring now to the housing or cup portionof my pin, it is herein sought to avoid the weaknesses inherent in prior forms,which provide a support for the tongue forward the pivot. A familiar method is to form this support or hearing byu'pwardly bending from the base of the housinga tongue, which after slight use collapses'and is forced downwardly and away from the remainder of the housing under the vertical pressure of the pin-tongue upon its uppermargin. In my structure this weakness is overcome by transverse walls integral with one of the housing sides. details are as follows: From a flat metallic sheet is cut a blank with the outline shown in Fig. 6. The blank consists of an oblong strip 6 i h, with openings 0 centrally located near each extremity. From both sides of the upper portion e of the strip project wings g f,

The;

having concaved upper-margins; but one or both margins may be straight,if desired. The

'cup or housing is completed by bending the parts as follows: The portion-i forms the base of the cup, and upwardly from this is bent in parallel planes theportionse and h of the blank forming the side walls of the housing or cup. The wings g andfof the blank are bent inwardly into parallel planes at right angles to the planes of the side walls, thus completing the housing. A pivot Z traverses theopenings 0 in the Walls'and the opening 0 in the pin-tongue, the latter being mounted upon the pivot intermediate the walls 6 and h, with the shoulder 61 above the pivot. The base i of the housing is fixed to the pin-bodyj in the usual manner, and the latter has the usual catch it.

In Fig. 10 the housing is shown without a front wall. In operation it will be noted that the top of the wall g forms abearing for the pintongue shaft when the latter is in engagement with the catch, while the upper margin of the rear wall f, in conjunction with the shoulder d, furnishes a limit to the backward travel of thetongue a.

What I claim as new is 1. In a pin, the combination with a'tongue having a head, a shoulder upon the head, a

pivot traversing the head, housing-walls in which the pivot is mounted, and means intermediate the walls for intercepting the shoulder when thetongue is raised.

2. In a pin,the combination with the tongue of a flat head upon its extremity, a shoulder upon the head, a pivot traversing the head, housing-walls in which the pivot is mounted and a rear housing-wall against which the shoulder is adapted to contact in its travel.

3. As a new article of manufacture, a housing comprising a base, side walls rising from said base, and a wing integral with one of the side walls and bent inwardly at right angles thereto.

4. In a pin, the combination with the tongue having a flat head upon its extremity, a shoulder upon the head, a pivot traversing the head, housing-walls in which the pivot is mounted, and a housing-wall against which the shoulder is adapted to contact when the tongue is raised.

5. In a pin of the class described, a bear- 1 housing comprising a base portion, side walls ing, a fixed stop member, and the pin-tongue provided with bearings for the pin and bent havingaperforated flattened head pivoted to i at right angles to said base portion, and a Is the bearing and having a shoulder on said wing integral with a side wall and bent at head for engagement with said fixed stop right angles thereto. member when said pin is raised. In testimony whereof I have affixed my sig- 6. Apin-tongue,a bearing therefor,said pin nature in presence of two witnesses. comprising a shaft and a erforated flattened T 1 head, a shoulder formed on said head, said GEORGE DOVER shoulder engaging said hearing when the pin is raised.
