AUTOMATIC FIRE-EXTINGUISHER.

$PECIFICATION forming part of Letters Patent No. 297,%32, dated April 22, 188%.

Application filed January 21, 1884.

To (ZZZ whom it may concern.

Be it known that I, WILLIAM Nmmonnn, of Cleveland, in the county of Guyahoga and State of Ohio, have invented a new and useful Improvement in Automatic Fire-Extinguishers; and I do hereby declare that the following is a full, clear, and exact description of the same.

My invention relates to automatic firesprinklers of that class in which the sprinkler is attached to a'pipe, said pipe being closed by a distributor held in position by fusible con nection.

The invention consists of an improved form of distributor, and of improved details of construction in the devices by which it is held in place.

In the accompanying drawings, Figure 1 shows a front elevation of a distributer with the pipe closed. Fig. 2 shows a similar elevation, with the pipe and valve in section. Fig.3 shows a side elevation on e-quarter turned from Fig. 1. Fig. 4 is a top view of the dis tributer. Fig. 5 is a side elevation of the same. Fig. 6 is a perspective view of the same. 1 Fig. 7 is a plan view of the supporting collar and frame. Fig. 8 represents a plan of a modified form of the distributer. Fig. 9 is a front elevation of the extinguisher, with the frame an d pipe or. body in one piece. Fig. 10 is a similar elevation, with the body and valve in section. Both these figures represent additional details hereinafter explained. Fig. 11 shows a horizontal section on line H M of Fig. 9.

In these drawings, Ais a tubular body,threaded and provided with faces for connection with the pipe end. To it is attached a frame, B, removable or integral therewith, which frame furnishes support for the distributer (3.

As shown in Fig. 2, the frame B is attached to ring D, screwed upon the body A, and vertically adjustable thereon.

The distributer O is a dish having a bottom provided with a central cone and a continuous rim, with salient angles or projections. The distributer may be star-shaped, as shown in Fig. t, or with angular projections, as shown in Fig. 8. In both cases the rim is vertically continuous; but as the different parts of the wall or rim stand at various angles to each other, they turn the water in an oppo- (No model.)

site direction, and throw it at angles as varying as those of the faces of the rim, as shown in Fig. 6 by the arrows. The distributer is placed and guided between the sides of the frame B, as shown in Figs. 1 and 4, and is held up against the lower end of the body Aby means of a post, F, having arms G. The postF bears against a spur on the bottom piece of the frame, and the upper part bears upon a second post, H, pressing directly against the concave boss or stud on the bottom of the distributer and valve. The post is brought into position to press firmly against the distributer, and both of the arms G are connected to the frame B by means of solder of low melting-point. The distributer, where it bears against the end of the tube, has an annular slat of solder or other fit material.

To bring the post F and arms G into proper position, an adjustable connection is convenient. This is furnished by the verticallyadjustable ring D; but a more convenient device is shown in Figs. 9 and 10, in which the supplemental post H has an extensible screw-plug, J. The bearings of the post H above and below are rounded, as shown, or made like balance-bearings, to allow the post to be straightened from a crooked position like a toggle-lever. It will be understood that when the arms G are released by heat the pressure of the water throws down the distributer. It is guided by frame B, and rests on pins E in said frame. In this position it is directly underneath the opening and receives the impact of the water. This is thrown by rebound up against the walls of the distributer, the bottom, and the inner faces of the rim in all directions, as above explained. Any accumulation of sediment is readily washed out, andno liability occurs of clogging.

In Figs. 9 and 10 is shown an annular plate, d, around the lower end of the body A, and sufficiently above its seat to admit the rim of the distributer. It is cast with A, and serves as a cover for the distributer, to exclude dust, and when in action the water thrown upward strikes against it, and is better distributed by K reason of its serrated edge shown in Fig. 11. The form shown in Figs. 9 and 10 has the advantage of simplicity in respect to A and 13, being cast in one piece, and in respect to the extensible plug in the post H, which may be turned up to close the valve after the solder has been applied.

I claim a 1. In an automatic fire-sprinkler, a distributer having continuous vertical walls with salient projections, said distributer being located to receive the water from the .pipe and to distribute it in various directions, substantially as described.

2. In an automatic fire-extinguisher, the distributer having vertical continuous wall, said wall being provided with salients and witha central cone, substantially as described.

3. In an automatic fireextinguisher, the body A, having frame B, and a distributer with supporting-posts and arms G, adapted by means of solder to hold the distributer to the body, substantially as described.

4. In a distributer, the body, a frame, a dis- 2o tributer adapted to close the body, a supporting-post having arms adapted to be connected to the frame by solder, and post H and extensible post J, the parts being constructed and arranged in their relation to each other sub- 25 stantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
