JOSEPH T. BRIGHT, OF MIDlVAY, KENTUCKY.

SPARK-ARRE'STER.

SPECIFICATION forming part of Letters Patent No. 568,735, dated October 6, 1896.

Application filed July 16, 1896. Serial No. 599,452. (No model.)

To all whom it may concern.-

Be it known that I, JOSEPH T. BRIGHT, of Midway, in the county of Woodford and State of Kentucky, have invented a new and useful Improvementin Spark-Arres ters, of which the following is a description.

My invention is an improvement in sparkarresters; and it consists in certain novel constructions and combinations and arrangements of parts as will be first fully described, and then pointed out in the claims.

In the drawings, Figure 1 is a sectional view of my spark-arrester. tion of one of the w'oven-wire sheets or wings with the hinge-plate attached and shows a notch in its lower edge. Fig. 3 is a representation of one of the woven-wire wings or sheets with hinge-plate attached and being straight on its lower edge. Fig. 4 is a sectional view of one of the woven-wire wings with hinge-plate attached. Fig. 5 is a representation of one of the lever-bars which are loosely riveted to the hinge-plates of the woven-wire wings. Fig. 6 is a representation of the perpendicular hinge-plate to which the woven-wire wings are hinged, having 3' ournalplates firmly fastened to one side of its face, also having slots cut through it to correspond with the slots in the journal-plates to admit the hinging ends of the hinge-plates on the woven-wire wings. Fig. 7 is a perspective View of the lever attachment by which the lever-bars that are attached to the hinge plates of the woven-wire wings are raised and lowered. Fig. 8 is a View of two bands with cross-plate, one of which is placed in each end of the cylinder and affords a fastening for the ends of the perpendicular hinge-plate.

The spark-arrester, Fig. 1, is composed of a cylinder A, made of sheet-iron, in each end of which is fixed a band 0, having a crossplate w, Fig. 8, to which the ends of the perpendicular hinge-plate 0, Figs. 1 and 6, are bolted through the holes 6 e. The perpendicular hinge-plate 0, Figs. 1 and 2, has slots cut through it to admit the passage of the hinge ends of the hinge-plates of the woven wire wings D D DD and D D D D, Fig. 1. On one side of the perpendicular hinge-plate 0, Figs. 1 and 6, are securely fastened journal-plates B B B 13, Figs. 1 and 6, having slots in them to correspond with the slots cut in Fig. 2 is a representathe perpendicular hinge-plate O to allow the hinging ends of the hinge-plates E to pass in.

order that the hinge-plates of the woven-wire wings D D D D and D D D D may be hinged together on the perpendicular hinge-plate 0, Figs. 1 and 6, by passing a wire through them in the journal-plates B B B B, Figs. 1 and 6. The perpendicular lever-bars J, Figs. 1 and 5, have eyeplates V V V V, placed at right angles to the face of the bar J, Fig. 5, and are loosely riveted through the eyeplates V V V V to the hingeplates E E E E E E E E, Fig. 1, of the woven-wire wings D D D D and D D D D, of which the woven-wire wings formed like D, Fig. 2, are 011 one side of the perpendicularhinge-plate G,and those formed like D, Fig. 3, are on the opposite side of the hinge-plate C, Fig. 1.

The woven-wire wings D and D, Figs. 2 and 3, have fastened to their surface hingeplates II and E by rivets, which pass through them and through the woven wire wings, thence through a plate I, Fig. 4, on the opposite side of the hinge-plate EH, Fig. 4.

The woven-wire wings I), Fig. 2, have a notch or square opening a: on their straight edges to admit of the parts 3 and a to pass by the edges of the perpendicular hinge-plate C when the woven-wire wings are spread, thereby closing any undesirable space that might exist between the edges of the woven-wire wings formed like D, Fig. 3, and the face of the perpendicular hinge-plate O.

In Fig. 1 m is a short section of sheet-iron cylinder which fits in or over the cylinder A, in which is constructed the lever-,which raises or lowers the lever-bars J, thereby raising or lowering the woven-wire wings.

The plate P, Figs. 1 and 7, is bent at right angles at each end, forming the uprights a and I), through which holes 7t" and Zare made in order that the lever-plate P can be firmly attached to the band 0, Figs. 1 and 8. Upon the surface of the lever-plate P, at one end, is fastened a journal-plate Said. journalplate has a slot 71 cut through its center to receive the end of thelever-arm M, which is hinged to the journal-platej by passing a wire or bolt y through a hole in the lower end of the lever-arm M. The lever-plate P also has a journal-plate Q, attached near the opposite end of it.

The journalplate Q is so constructed that the bolt 9, which passes under the surface of the journal-plate Q, through the lower end of the lever-arm H, is allowed to slip backward and forward as the lever-rod O, which passes through the hole .2, is loosely bolted to the lever-arm N by the bolt t, is pulled backward or pushed forward by the hand-lever p as operated by the engineer. The perpendicular leverarm L is loosely attached between the upper ends 01' the lever-arms M and N by a bolt 2, passing through all three of them. A bolt K is passed through one end of the le- Yer-bars J and the upper end of the lever-arm L, thence through the end of the other leverbar J. The lever-rod O has a slit in the end that is loosely bolted to the lever-arm N at t, and from thence passes through the upright a at Z, Fig. 7, and is loosely attached to the handlevcrp at r, Fig. 1. The hand-leverp, Fig. 1, is jointed or hinged to a hinge-clip S at a by a bolt. Said hinge-clip may be fastened to the most desirable portion of the engine in order to allow the hand-leverp to be in easy reach of the engineer. The ratchetbar (1 has a brace 6, which may be put at any desirable point that will allow the lever-arm p to be kept in any desired position firmly.

In Fig. 1 the flange 5 is made to fit inside the cylinder A and to project over the top of the smoke-stack and fixed firmly to it by bolts passed through the holes '7 7, thereby holding the spark-arrester firmly in position.

Vhen the hand-lever p is moved toward the smoke-stack in which the spark-arrester, Fig. 1, is fixed, the lever-rod O pushes the lower end of the lever-arm N toward the center of the lever-plate P and raises the upper ends of the lever-arms l\.[ and N, thereby raising the lever-arm L, which is loosely bolted to the ends of the upright lever-plates J, thereby raising them, and as they are loosely riveted to the hinge-plates II E, Fig. 4:, of the woven-wire wings D D D D and D D D D,

so the woven-wire wings can move freely upon the upright lever-bars, and the hingeplates of the woven-wire wings are hinged 011 each side of the perpendicular hinge-plate C, the woven-wire wings are closed, and when the hand-leveris pulled away from the smokestack the woven-wire wings are opened; but when the complete section of the woven-wire wings is reversed in the cylinder A and the bolt \V passed through the lever-arm L then the movement of the woven-wire wings will be reversed as the hand-lever p is operated by the engineer. \Vhen the woven wire wings are spread, no sparks can pass out of the smoke-stack.

Having thus described my invention, what I claim as new is- 1. In a spark-arrester consisting of a cylinder in which are several wovenwire wings, hinged to a perpendicular hinge-plate,which is fixed through the center of the cylinder by the aid of cross-plates which are fastened to bands, which are fastened to a cylinder on its inside, and upright lever-bars which are attached to l1inge-plates, which are attached to woven-wire wings and lever-arms operated by a hand-lever through which the wovenwire wings are opened or closed at the will of the engineer, substantially as set forth.

2. The combination of the hand-lever with the lever-rod,the lever-arms,the lever-plates, the lever-bars, the hinge-plates, the wovenwire win gs,the ratchet,the cylindcr,thc bands with cross-plates, the flange that laps over the top edge of the smoke-stack, to keep the cylinder in position, the reversibility of the woven-wire wings in the cylin der, all of which is under the control of the engineer, to spread or close the woven-wire wings by the operation of a hand-lever, substai'itially as set forth.
