(No Model.)

NITED STATE PATENT OFF E.

MORTIMER O-. TURNER, OF MARQUETTE, MICHIGAN.

SECURING DEVICE FOR CARRIAGE-CURTAINS.

SPECIFICATION forming part of Letters Patent No. 536,321, dated March 26, 1895.

Application filed April 12, 1894. Serial No. 507,296. (No model.)

To all whom it may concern:

Be it known-that I, MORTIMER O. TURNER, a citizen of the United States, residing at Marquette, in the county of Marquette and State of Michigan, have invented certain new and useful Improvements in Devices for Securing Carriage-Curtains; and I do.declare the following to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

This invention relates to certain new and useful improvements in devices for securing carriage curtains of that class in which an eyelet or the like is secured to the one part and a button or the like is secured to the other part and adapted to enter the eyelet and hold the curtain against accidental displacement, yet permitting of ready detachment of the curtain when desired. The novelty in the present instance resides in the peculiar construction of the button-head whereby no twisting of the curtain is necessary and whereby the latter cannot become accidentally disengaged or detached. I form the button with a beveled base and an angular head having spiral ribs extending in the direction of the length of the button, by which construction the forcing of the eyelet over the button-head automatically gives to the curtain suflicient twist to allow the head to pass through the eyelet when the curtain automatically assumes its normal position as will be hereinafter explained. The bevel of the base performs an important function in connection with thespirals of the head, as it allows the head to seat itself in place and permits of the necessary movements of the curtain without any danger of displacement or undue lateral movement. Furthermore, the bevel of the base allows the head to enter entirely through the opening in the eyelet and thus there is an abutment upon both sides of the curtain to prevent its movement by the wind or otherwise.

Other objects and advantages of the invention will hereinafter appear and the novel features thereof will be'specifically defined by the appended claim.

The invention is clearly illustrated in the accompanying drawings, which, with the letters of reference marked thereon, form a part of this specification, and in which Figure 1 is a perspective view showing the two parts of the eyelet separated, said parts being shown upon an enlarged scale. Fig. 2 is a perspective view of the button. Fig. 3 is a sectional view taken through the eyelet attached to a carriage-curtain, with the button in place with its head passed through the eyelet. Fig. 4. is a front elevation showing the head passed through the eyelet.

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

Referring now to the details of the drawingsby letter, A designates the main plate of the eyelet which comprises acircular disk of metal which at its center is provided with an angular opening A, and at its edge provided with the prongs or points B, extending at right angles from the face of the plate as seen best in Fig. 1.

O is a washer having a central opening 0 as seen in Fig. 1.

In attaching the eyelet to the curtain, the points or prongs B of the plate A are forced through the curtain which should be provided with an opening'coincident with the opening A in the said plate, and the washer or plate 0 being placed upon the opposite face of the curtain the prongs or points are bent or folded over the edge of the washer as seen in- Fig. 3.

The button D is provided with a shank by which it is retained in the proper position upon the carriage frame, and with a head E comprising a body portion or base F the outer face of which is beveled toward the head as shown at G, and outward beyond this beveled base extends the head H angular in form as seen and this head or angular portion is provided with the spirally-arranged ribs or edges which terminate at the base at their inner ends and at the corners of the angles of the head at the outer end as clearly shown.

In fastening the curtain, all that it is necessary to do is to place the curtain against the ICO head of the button with the angular opening of the eyelet against the head and press on the curtain as if to force it over the button, when the spirals of the head will automatically cause the curtain to twist or turn sufliciently to allow the eyelet to pass over the head and as soon as the head has passed the inner face of the washer the curtain will antomatically assume its normal position. The bevel of the base entering the opening in the eyelet serves to prevent displacement and also limits the lateral movements of the curt tain.

once evident that a button head having five,

six, or any other desired number of sides may be used in lieu of the triangular head shown, and my inventioncontemplates modifications in the form of the button head as well as in the form of opening in the eyelet.

What I claim as new is- The improved carriage-curtain fastening device herein described, consisting of a plate with attaching means and an angularopening, and a button having a shank, a base portion beveled outwardly, and an angular head beyond the base and provided with spirallydisposed ribs extending from the corners of the angles of the head inward and joining with the beveled base, whereby in engaging the parts the plate is automatically turned to admit of the passage of the head and, when engaged, the bevel of the base will prevent undue movement of the curtain, substantially as herein shown anddescrib ed.

In testimony whereof Iaftix my signature in presence of two witnesses.
