AUTOMATIC FIRE-VEXTINGUISH ER.

SPECIFICATION forming part of Letters Patent No. 439,293, dated October 28, 1890.

Application tiled August 6, 1889.

.To all whom, it may concern:

Be it known that I, WILLIAM J. FRASER, a citizen of the United States, residing at Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented certain new and useful Improvements in Automatic Fire-EX- tinguishers; and I do hereby 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 letters of reference marked thereon, which form a part of this specification.

This invention relates to such systems of automatic tire-extinguishing apparatus as embodya series of pipes suitably supplied with water under pressure, and led along 'the ceilings of rooms to be protected, such pipes being provided at intervals with sprinklerheads. These sprinkler-heads are some form of device designed to automatically open the pipes for the admission of waterto the room, and usually embody some special means for spreading or distributing the water issuing from the pipes. Said sprinkler-heads are applied beneath or above or at the side of the pipes extending horizontally` along the ceilings.

My improved sprinkler-head is shown in a portion of the drawings las applied beneath the horizontal pipes, and in a portion of thedrawings as being applied above said pipes. It may also be applied to the side of the pipes.

The object of this invention is to provide an apparatus the parts of which are small in number and simple in form.

In the accompanying drawings, Figure 1 is a side view of one of the sprinkler-heads applied beneath the horizontal pipe. Fig. 2 is a similar view of one of the sprinkler-heads applied above the horizontal pipe. Figs. 3,4, and 5 show modications of the sprinklerhead.

Referring to Fig. l, A is a horizontal pipe extending along the ceiling. y B is a branch pipe standing at right angles to the pipe A and joined thereto by a T- coupling A', or said branch pipe may be one of the arms of the T-coupling.

The pipe A may be of any suitable size to Serial No. 319,909. (No model.)

convey a sufficient volume of water to a desired number. of sprinkler-heads, and the branch pipe B may be of proper size to deliver into the room the volume of water desired in that portion of the room. Said pipe B is threaded exteriorly to receive the interiorly threaded sleeve C of the frame O. By thus applying the frame O upon the pipe B said frame may be adjusted longitudinally upon said pipe, so that whatever said frame supports is carried nearer to or farther from said pipe, depending upon the direction in which said frame and its sleeve are turned.

C2 C2 are arms of the frame C, connected below by the horizontal bar O3.

D is a deflector held against the opening of the pipe Bby the support D. One end of said support rests upon a hip or equivalent device c2, supported by the frame C below the dei-lector, while the opposite end of said sup- Y port rests upon one end of a bar c3, pivoted at its middle to the frame C. Said bar is prevented from turning by the yokeD2, having the laterally-directed arms O2, one of which rests over the outer end of the bar C3 and the other of which rests over some portion of the frame C-as, for example, a projection c. Said projection c holds the lower portion of the yoke, and the upper arm d2 of the yoke is made'to hold the bar c3, so that the inner end of the latter is held immovably against the support D. Y

E is an expansion device supported by the lower portion of the frame O, and arranged to force the yoke D2 outward until it is freed from engagement with the bar c3 and the projection c. Said expansion device may be of any suitable form; but I prefer to use the form shown in the drawings. The same consists of a chamber E', filled with suitable expansive material, and a piston E2, extending outward from said chamber toward or against the yoke D2, so that when said expansive material expands the piston is driven forward to dislodge the yoke D2. lVhen the yoke D2 is thus dislodged, the bar c3 yields and the support D and the deiiector E fall, thus allowing the water to iiow from the pipe B. The deector D may be made larger than the IOC frame C, and the arms C2 made to extend Y through slots d in said deiector. vThen-when said deflector falls it will be engaged by the hip c2 and the bar d3 and held at a Iixed dis-y tance fromvtlie opening of the pipe for the distribution of the water.

In Fig. Zthe head is in all respecislike that shown in Fig. 1, excepting that it is reversed and located above the pipe A.

In Fig. 3 the frame C is applied to the end of the pipe B, as in Fig. l, but the lower bar C3 is omitted and one of the arms C2 is shortened. The longer arm G2 has at its lower end the inwardly-directed lug c4; and the shorter arm has the outwardly-directed lug The expansion device E is similar to that shown in Fig. 1, but it is held in place by the lug c" and the yoke D2. One end or side of the expansion device rests upon thelug` c4. while at the other end the upper arm ot' the yoke D2 rests upon the lug c5, and the lower arm of said yoke rests against the lower side of said expansion device, so that said expansion device is held at that side by said yoke, and the piston E2 is directed toward said yoke. Thus said expansion device is held stationary by said yoke so long as the latter is in engagement, but is released when said yoke is dislodged by the forward movement of the piston. The deector D is then supported upon the expansion device E until said expansion device falls, whereupon said detlector also falls until it meets the hip c2 and the lug c5.

In Fig. 4 the frame C is applied to the pipe B, as in Fig. 1, and the expansion device is put into a vertical posi-tion beside or as a part of one of the arms C2, the piston being directed upward. F is a support, having a point f bearing against a cap G, resting over the opening of the pipe B. Said support has another point f bearing against the frame C or the expansion device E at a point below and at one side of the point f. Said support Fhas also an arm f 2 extending upward nearly over the pointf and beside the upper end of the expansion device E. Alug f3 projects from the arm C opposite the arm f2, and a yoke D2 is applied over said lug and said arm f2, so as to hold said support iinniovably in position. The rising of the piston of the eX- pansion device under abnormal heat dislodges the yoke D2 and allows the support F and the cap G to fall.

In Fig. 5 the parts are the same as in Fig. 4, excepting that the support F and expansion device E are united and together seated upon the frame C, as is said support alone in Fig. 4, and the yoke D2 engages said lug f3 and the upper end of the expansion-chamber E. The upward movement of the piston E2 dislodges the yoke D2 and allows said expansion device, support F, and cap G to fall. In this form said expansion device may, in a certain sense, be regarded as a part of the support for the cap G.

I do not claim herein a wedgeblock for holding a valve on its seat and a lock-pawl fo-r holding said wedge-block in place until such pawl is released by an expansion device.

In another application filed by me September 6, 1889, and bearing Serial No. 323,216, I claim, broadly, the combination, with a water-supplypipe having an opening for the delivery of water, of a traine applied to said pipe, a valve placed over said opening, a part supported by said frame and constituting a portion of the support of said valve, and a movable member constituting another portion of the support of the Valve, and an expansion device having a suitable part arranged to dislodge said movable member. The scope of the claims hereto appended is therefore to be limited to combinations embodying a yoke, the engaging portions of which are not hinged or coupled to the parts which they engage.

I claim as my invention- 1. In an automatic fire-extinguishing apparatus, the combination, with a pipe B, of a frame C, applied to the pipe B and a part resting over the opening of said pipe and held forcibly against said opening by another part, forming a support therefor and supported by said frame, a yoke holding said part constituting the su pport in position, and an expansion device to act directly upon said yoke, so as to force the latter outv of engagement under abnormal heat, whereby the part closing the opening of said pipe is released, substantially as shown and described.

2. In an automatic fire-extinguishingapparatus, the combination, with a pipe B, of a frame C, applied to the pipe B and a part resting over the opening of said pipe and held forcibly against said openingby'another part, forming a support therefor and supported by said frame, a yoke holding said part constituting the support in position, and an expansion device to act directly upon said yoke, so as to force the latter out of engagement under abnormal heat, whereby the part closing the opening of said pipe is released, such expansion ,device consisting of a chamber and piston,said chamberbeing filled with a suitable expansive material, substantially as shown and described.

3. In an automatic fire-extinguishing-appar'atus, the combination, with a pipe B, of a frame C, applied to the pipe B and a part resting over the opening of said pipe and held forcibly against said opening by another part, forming a support therefor and supported by said frame, a yoke holding said part constituting thesupport in position, and an expansion device so arranged with reference to said yoke as to act directly upon the latter and force it out of engagement under abnormal heat, whereby the part closing the opening of said pipe is released, said support, expansion device, and yoke being supported adjustably upon said pipe, substantially as shown and described.

4. In an automatic tire-extinguishing apparatus, the combination, with a pipe B, of a frame threaded adjustably around the end of said pipe, an expansion device resting upon one side of said frame and supported from IOO IIO

the other side of said frame by means of a yoke so located as to be forced out of engagement by the movement of a part of the eX- pansion device, and a part applied over the opening of said pipe and held against said opening by a support from said expansion device, substantially as shown and described.

5. In an automatic fire-extinguishing apparatns, the combination, with a pipe B, of a' frame threaded adjustably around the end of said pipe, an expansion-chamber resting upon one side of said frame and held against said frame at the other side by means of a July, 1889.
