WILLIAM I L-EVORY, OF BROOKLYN, NEW YORK.

PLUMBERS TACK.

SPECIFICATION-forming part of Letters Patent No. 508,822, dated November 14, 1893.

Application filed October 20, 1892. Serial No. 449,448. (No model.)

To all whom it may concern: 7

Be it known that I,W1LLIAM, H. EVORY, of Brooklyn, in the county of Kings and State of New York, have invented a new and Improved Plumbers Tack, of which the following .is a full, clear, and exact description.

My invention relates to improvements in plumbers tacks such as are used to support pipes upon the side of a wall.

The object of my invention is to produce a tack of this description which may be quickly and firmly clasped around pipes of different sizes, and which also may be easily and securely fastened to a wall so as to hold the pipe to which it is attached in a secure manner.

7 To this end my invention consists in certain features of construction and combinations of the same, aswill be hereinafter described and claimed.

Referenceis to be had to the accompanying drawings forming a part of this specification, in which similar figures of reference indicate corresponding parts in all the views.

Figure 1 is a'front elevation of the tack embodying my invention showing it applied to a pipe. Fig. 2 is a rear elevation of the same with parts in section, showing also the arraf ge- 1g. 3 is a cross section through the tack and pipe on the line 33 in Fig. 1. Fig. 4 is a cross section of a modified form of tack, showing it applied to a pipe; and Fig. 5 is a cross section of another modified form which is adapted for use in supporting two pipes.

The tack comprises two oppositely arranged leaves which have convex inner portions 10 adapted to fit upon a pipe, and whichhave also depending flanges 11 at the edges so as to form each leaf into a sort of case adapted to contain the adjusting rod or the holding bands, as hereinafter described. Each leaf is also provided with holes 12 inwhich the fasrtening screws 13 are inserted to attach the tack to the wall. The two leaves are connected on their outer sides by bands 14 which extend through, openings 15 in the leaves and which are, adapted to extend around a pipe and clamp it firmly in place. The bands at one end are rigidly secured to one of the leaves 10, as shown at 16 in Figs. 2 and 3, and. the opposite ends of the bands are attached at 17, to a split rod, or shaft 18. The bands 14 are made preferably of spring material and i the tension of the coil is usually enough to fasten a pipe. The split rod or shaft turns in bearings 19 and the rod may be turned so as to tighten the bands 14 by winding them upon site the ends of the rod or shaft, as shown at 20 in Fig. 2', so as to permitthe application of the key. It will be seen, that by the rotatable shaft, the bands may be taken up or shortened to any desired extent, '6. a, unlimitedly to adapt them to clamp any size of pipe. When the shafts, 18, are turned to tightenthe bands, 14, the strain on the latter tends to separate the members of the shafts, so that the latter bind'in their sockets, or bearings, and thus retain their positions and hold the bands under strain to the required degree.

The bands 14 are adapted to extend around a pipe 22 and after they are passed'around the pipe the leaves are held together behind the pipe by a book 23 which is secured to one of the leaves 10 near one edge, as shown at 24, and which at its free end is adapted to engage a slot 25 in the opposite leaf, asshown clearly in Figs. 2 and 3.

Inapplying the tack to a pipe one of the leaves is passed over the pipe, after which the hook 23 is made to engage a slot 25, and the pliability of the bands 14 permits this to be easily done. After the leaves are applied and fastened together they are secured to the wall by means of screws and the pipe is thus held in place. In Fig. 4 I have shown a form of tack which is on the same principle as the form already described, but which is adapted to be applied and fastened on one side of the pipe, as certain positions in buildings are such that two leaves cannot be conveniently ap plied. Here the leaf 10 is like one of the leaves already described, with certain slight modifications which will be described below. The leaf is provided with the bands 14 and with a shaft 18, like that already described, to which the bands are fastened at one end. The opposite ends of the bands are fastened to a supplemental leaf 27, as shown at 26, which leaf is arranged to swing within the leaf 10 and is hinged to the inner portion of the leaf, as shown at 28. The free end of the leaf 27 is adapted to be held within the leaf 10 by aspring catch 29, and the leaf has perforations 30 opposite the perforations 12 in the leaf 10, so that the fastening screws may pass through both leaves. The hinge at 28 is formed by simply engaging pintles on the leaf 27 with recesses in the leaf 10, as shown clearly in Fig. 4, but any other kind of detachable hinge may be used.

It will be seen, that in both forms of tack the two members, or leaves are held detachably connected by certain means so that they may be easily separated when required.

I 5 In applying this tack the leaf 27 is passed around the pipe 22, taking the band 14 with it, after which the leaf is hinged to the leaf 10 and forced upward into the same, as shown in Fig. 4, when the whole tack is in position to be screwed to the wall. The form of tack shown in Fig. 5 is adapted to fasten two pipes together and illustrates the fact that the tack may be made to fasten any number of pipes. Here the leaves 10 are each provided with :5 split shafts'18 to which the bands 14 are secured, as already described, and a center-piece 31 is interposed between the leaves and hinged to one of them, as shown at 32, this piece having a central rib 33 which extends between the two pipes 22 which are fastened by the tack, and the walls of the center piece diverge and curve so as to form practically continuations of the curved surfaces 10 of the leaves 10. The free edge of the center piece is pro vided with a hook 23 which is fastened to one 35 of the leaves 10 in the manner already described.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. A pluinbers tack comprising two separable leaves adapted to be secured to a wall, pipe bands which are attached at one end to one of said leaves, and a rotatable shaft jour naled in-the other leaf and to which the other ends of the bands are detachably connected, and around which they are wound, unlimitedly, for clamping any size of pipe, as shown and described.

2. A plumbers tack comprising two sepa- 5o rable leaves adapted to be secured to a wall,

a catch holding the said leaves connected, and bands attached to-one of the leaves and to a rotatable shaft journaled in the other leaf, as shown and described.

3. In a plumbers tack, the combination, with a recessed leaf, or member,-adapted to support a pipe and for attachment to a-wall, of a supplemental leaf, or member, 27, adapted to be held in the recess in the other leaf, means for holding the supplemental leaf de: tachably in place, and pipe-clampingbands, and a rotatable shaft for taking up the bands, as shown and described.
