CARRIAGE-CURTAIN FASTENING.

SPECIFICATION forming part of Letters Patent No. 269,337, dated December 19, 18$ 2.

Application filed October 28, 1882.

To all whom it may concern Be it known that I, ADOLPHUS G. SNELL, of New Haven, in the county of New Haven and State of Connecticut, have invented a new Improvement in Carriage-Curtain Fastenings; and I dobereby declare the following, when taken in connection with accompanying drawings and theletters ofreference marked thereon, to be a full, clear, and exact description of the same, and which said drawings constitute part of this specification, and represent, in-

Figure 1, a front "iew; Fig. 2, side view; Figs. 3 and 4, views showing the disk in the two positions of the button Fig. 5, rear view of the base with the disk removed Fig. 6, the disk detached Fig. 7, vertical central section.

This invention relates to an improvementin the device for securing carriage-curtains, cominonlycalled carriage-button. Thesebuttons are attached to the posts or parts of the carriage, and the curtain provided with an opening like a button-hole, to be passed on over the button and be thereby secured. The heads of these buttons have been made so as to stand in line with the hole in the curtain, and so that the hole might pass freely over the button, and then the button turned at right angles to'the slit or hole, so as to prevent its accidental detachment. It is to this class of buttons that my invention particularly relates, the object being to improve the devices whereby the button is locked either in the position to receive the hole in the curtain or turned into a transverse position to secure the curtain. Suchlocking devices have been employed in connection with such buttons; but usually there has-been more or less play required for the shank of the button in its bearing. This play causes a wear of the parts. which soon renders them almost useless; and my invention, whereby these difficulties are overcome, consists in the construction of the button as hereinafter described, and more particularly recited in the claims.

A represents the base or plate, which is secured to the post or stationary part of the carriage, and at points corresponding to the button-holes through the curtain. On its outside center is a raised projection, forming a body, B, onto which the button-hole of the curtain will pass, and is in extent at least equal to the thickness of the curtain at the button hole.

It is oval in shape, and centrally through itis- (No model.)

a hole forming a seat for the shank a of the button C. The button C corresponds in shape to the body B, and is arranged so as to turn upon its shank a in a plane parallel with the base A, say, from the position seen in Fig. 1 to the position seen in broken lines, same figure-thatis, its normal position is shown in full lines,and turned into its transverse position in broken lines, and when so transversely turned its ends project beyond the sides of the body B, as indicated in Fig. 1. The back or rear side of the base A is recessed, as at b, (see Figs. 5 and 7,) to receive a disk, (I, as seen in Figs. 3, 4, and 7, the disk shown detached in Fig. 6. This disk is recessed at its center, as at e, and has a central hole, through which the end of the shank a extends, and is riveted down upon the disk, as seen atf, Fig. 7, and so that the collar then serves as the means for retaining the button in its place-that is, prevent its movement in the direction of the axis of its shank, but yet permitit to turn freely upon its shank as a center. The riveting of the shank upon the disk is made to secure the two parts together, so that the disk will turn with the button. This may be done by making the hole through the disk of irregular shape, as seen in Fig. 6, and the shank of corresponding shape, or otherwise, it only being essential to the invention that the disk shall revolve with the button.

On one side of the disk a tongue, h, is out concentric with the center of the disk, the out being of sufticient length to give considerable elasticity to the tongue. At the end of the tongue an indentation from the outside, as at 2', forms a corresponding projection on the opposite side, as seen in Fig. 7.

In the cavity on the back of the base in which the disk rests are several depressions, m m and n n, (see Fig. 5,) each of which correspondsto and standsin the path of the inward projection, t, on the tongue 11. The depressions m and a and the projection i are conical in shape, so that while the projection on the tongue will fall into those depressions a little power applied to the button to turn it will force the projection ifrom the depression with which it may be engaged, the spring of the tongue yielding for that purpose. The indentations are made-say those at n-in the vertical line of the button when standing in the position seen in Fig. 1, and so that when the button is in that condition it will be held by the projection 43 standing in one of these depressions n, and as seen in Fig. 3, but when turned at right angles thereto the projection twill fall into one of the depressions m, as seen in Fig. 4, and thus will secure the button in either of the two positions. The two depressions a n, being opposite each other,will secure the button if it be turned either end up, and so that the depressions m m will secure the button whichever way it may be turned into its transverse position. A single depression at and a single depression m will serve the purpose of securing the button, provided always that the button be turned to either one of those two positions.

By this construction the button has no a xial movement in order to enable it to be locked in either its fastening or unfastening position, but is firm in its seat.

The disk may be sufliciently elastic without the cutting of the tongue therefrom; but I prefer to cut the tongue, as it gives a better spring, and one less liable to set.

Instead of making the projection on the tongue, it may be made on the body, and the depression in the tongue; yet I prefer the first construction. 1

I claim- 1. The base A, constructed with the body B, to receive the curtain, combined with the button G, having its shank a through the body, i

with a disk secured to the shank upon the reverse side, so as to turn with the button, the disk and body provided with corresponding indentations and projections, whereby the button will be held in either of its two positions, substantially as described.

2. The base A, constructed with the body B, the button O, having its shank to extending through said body, and so as to be turned in a plane parallel with the base, the base constructed with a recess on its rear surface, and a disk in said recess secured to the shank of the button, and so as to rotate in said recess with the button, the body and disk constructed with corresponding projections and depressions, whereby the button is locked in either of its two positions, substantially as described.

3. The base A, constructed with the body B, combined with the. button G, having its shank through the body, and so that the button will turn in aplane parallel with the base,and adisk on the rear surface of the plate secured to the shank of the button, and so as to revolve with the button, the said disk constructed with atongue, 1:, the said tongue and the surface of the plate over which it moves provided with corresponding projections and depressions, whereby the button is secured in either of its two positions, substantially as described.
