4 Claims.

This invention relates to an upholstery fastener, and particularly .pertains to a doily pin.

Various types of devices have been provided to fasten doilies or upholstery covering onto articles of furniture. In most cases these have involved the use of a head element which may be easily caught to withdraw the pin, and in some instances various complicated structures have been provided to penetrate the upholstering in an effort to prevent the pin from becoming displaced. These structures have been complicated and required considerable effort to properly place them in position. It is desirable, therefore, to provide a dolly pin of small dimensions and simple construction whereby the pin may be easily placed in position and may not be accidentally pulled from position or worked out of place. It is the principal object of the present invention, therefore, to provide a simple pin structure which may be easily inserted through fabric, and hold in position so that the head will be substantially concealed and so that the pin will not be accidentally removed.

The present invention contemplates a doily pin having a head structure designed to lie substantially flat on the surface of a doily or upholstering and having a head structure carrying yieldably prongs capable of being held close together while the pin is inserted through a fabric article and which will expand beneath the fabric to hold the doily pin in place.

The invention is illustrated by way of example in the accompanying drawing, in which:

Figure l is a plan of a doily pin embodying the present invention and showing the pin in its normal position before being placed within a piece of fabric.

Fig. 2 is a view in end elevation taken in the direction of arrow 2 in Fig. l and showing the doily pin with the straight pins thereof (in full lines) compressed prior to causing said straight pins to penetrate a piece of fabric. This view also shows said straight pins (in broken lines) spread apart at a wide angle of divergence as when freed completely from restraint.

Fig. 3 is a view in elevation showing the pin in place with the straight pins thereof spread oppositely to hold the structure.

Referring specifically to the drawings, the invention is there shown as embodied in a doily pin l which is adapted to be applied to secure a doily d to a piece of upholstery fabric H. In its preferred form, the invention comprises a single wire made of spring steel in which loops I2 and I3 are formed so as to be equi-distant from the center which will 2 of the wire and at opposite ends of a straight central length M of said wire which forms the mandrel of a head M of the doily pin. Head I4.

is formed by coiling opposite free ends of said wire about said mandrel to. form coiled springs l5 and 16 which extend from the loops l2 and [3 to the middle of the mandrel M. The coil springs 15 and I6 are preferably wound in opposite directions about the mandrel l4 and terminate at their inner ends in pins l! and I8 which are substantially straight from the points of their connection with springs l5 and I 6 to their outer extremities. The outer ends of said pins l1 and I8 are pointed so that they will readily penetrate a doily d and the fabric II on which it is desired to mount said doily. T

The doily pin I0 is manufactured so that the straight pins l1 and I8 thereof, when free from restraint, will be held by their connection with springs 15 and H5, in widely divergent positions as shown in full lines in Fig. 1 and in broken lines in Fig. 2. To prepare the doily pin ill for insertion through the doily d and into the fabric H to which it is desired to secure said doily, the pin body i4 is seized between thumb and forefinger so as to swing the straight pins l1 and Hi from their extended positions (shown in broken lines in Fig. 2) to the positions in which they are shown in full lines in Fig. 2 in which said pins are substantially parallel.

With the doily pin it) thus gripped between the thumb and forefinger, the points of the straight pins l1 and I8 are inserted through the doily d and into the upholstery fabric H. The doily pin II) is now released from the grip with which it has been held between the thumb and forefinger, and is pressed towards the doily d to extend straight pins l1 and I8 practically their full length into said doily and the upholstery fabric H to form a depression in said doily and fabric which is occupied by the body H of the doily pin ill.

As said body is thus pressed inwardly against said doily, the straight pins l1 and [8 swing outwardly at a widely divergent angle as shown in Fig. 3 so as to secure the doily d to the fabric l I. With the doily pin [0 so applied, the body l4 thereof is practically sheltered in the depression formed in the exposed surface of the doily d,

against any accidental engagement of the body V H of the doily pin 10 which might tend to dislodge this.

The doily pin in thus remains installed as shown in Fig. 3, until a very vigorous pull is exerted on the doily d tending to strip it from the upholstery fabric H, or until the doily pin I0 is deliberately removed from the position in which it is shown in Fig. 3 by the body l4 being gripped between the forefinger and thumb and pulled outwardly to withdraw straight pins I! and I8 from the doily cl and fabric I I.

It is to be noted that in case the pins H and I8 are withdrawn from the fabric H by pulling on the doily d, the doily pin it is not lost but remains anchored in place in the doily d by the straight pins H and !8.

Having thus described our invention, what we claim and desire to secure by Letters Patent is 1. A fastening device comprising: a wire man'- drel; a pair of wire springs coiled about said mandrel and secured at their outer ends to said mandrel; and a pair of substantially straight wire pins formed on the inner ends of said springs; said pins, when not under restraint, being held by said springs at a wide angle of divergence.

4. A doily fastening device formed of a continuous length of spring wire, said device comprising: a. central portion of wire, loops formed at the opposite ends thereof, the free ends of said wire being coiled about said central portion between said loops and in opposite directions to form two coils and a pair of pins formed by the e'iidfnost portions of said wire at the inner ends of said coils, said pins being pointed at their ends and being substantially straight from their junction with said coils to the outer extremities thereof and free of any encumbrance which would prevent their penetrating a fabric their full length, said coils being tensioned to swing said pins in oppositedirections, to dispose said pins, when the latter are unrestrained, at a wide angle of divergence.
