8 Claims. (01. 121-2) v This invention relates to a bell ringing device for locomotives, the general object of the invention being to provide automatic means for ringing the bell when the locomotive is in motion, the ringing ceasing when the locomotive is. not I in motion, whereby the ringing of .the bell is not left to the action of the engineer.

This invention also consists in certain other features of construction and in the combination and arrangement of the several parts, to be hereinafter fully described, illustrated in the accompanying drawings and specifically pointed out in the appended claims.

In describing the invention in detail, reference will be had to the accompanying drawings whereinv like characters denote like or' corresponding parts throughout the several views, and in which:--

, Figure 1 is an elevation of the front part of a locomotive, showing the invention appliedthereto.

Figure 2 is a vertical sectional view through the invention.

4 In these drawings, the device is shown'at A and is located on any suitable part of the front part of the locomotive and consists of a hollow base 1 forming an air chamber 2 which has an opening in one end thereof closed by a plug 3. A pipe 4 is in communication with the other end of the chamber and leads to the pneumatic bell ringer B of the bell C. The bell ringer is of the usual or any desired type. A cylinder 6 has a reduced part 7 provided with a flange 8 which is bolted to the top of the base 1, as shown at 9. A sheet 10 of asbestos packing is located between the parts to retard transfer of ,heat from the base to the lower part of the cylinder. The cylinder has a head llbolted theretoand a piston 12 is located in the cylinder and has a stem 13 depending into the reduced part '7. A valve chamber 14 is formed in a part of the wall of the cylinder 6 and is in communication with the cylinder through the port 15, the chamber having a reduced lower part 16, the junction of whichwith the large part forms a valve seat for a ball valve 1'7. A pipe 18 connects the large part of the valve chamber 14 with either end of either cylinder 19 of the locomotive and a pipe 20 connects the lower end of the small part 16 with the steam supply pipe 21 of the locomotive and a pipe 22 connects the cylinder, at the point of junction of the lower part thereof with the reduced part 7, with the exhaust passage of a locomotive cylinder, or this drain pipe 22 may exhaust at any other e convenient point.

An air cylinder 23 is bolted to the top of the cylinder 23 for the passage of a lever 38 which throttle is opened, 'steam' will pass through the chamber 14 of the cylinder 6. Y v steam going to the locomotive cylinders will cause the locomotive to move in the usual'manner and base 1, as shown at 24, and has a sheet 25 of asbestos or the like insulating it from the baseand this cylinder has a head 26 bolted thereto and a passage 27 connects the lower part of the cylinder H with the chamber 2. A pipe 28 connects the upper part of the cylinder 23 with the air reservoir 5 of the locomotive. A sleeve 29 is located in the lower part of the cylinder 23 and the upper end thereof forms a valve seat for'a ball valve 30 which separates the upper end of the passage 27 from the pipe 28, the sleeve having a port 31 therein which registers with the upper end of the passage 27. Acup'member'32, formed of asbestos or the like, seats on a steel tip 33 and a I bolt 34 passes through a sleeve 35, through a hole 7 in the cup member into the tip and these parts form a stem for the valve 30. An opening 36 is formed in the lower part of the cylinder Band anopening 37 is formed in the lower part of the ha'sa notch 39 adjacent one end thereof which 5 fits over a fulcrum projection 40 on a plate 41 fastened to the top of the base by a screw 42.

'Thus it will be seen'that when the locomotive steam pipe 21 into the cylinders 19 of the 1000- o motive and some of this steam will pass through the. pipe 20 into the lower part of the valve Of course, the

the steam passing through the pipe 20 will lift 'the valve 17 so that 'the steam will pass through the chamber l4and through port 15 into the cylinder 6 and the pressure of this steam in the cylinder 6 will cause the piston 12 to move downwardly so that its stem will rock the lever 38 so 'as to raise the short end thereof so that the valve stem in the cylinder 23 is raised, which I 'unseatsthe valve 30. When this occurs, air from the reservoir 5 of the locomotive passes through the pipe 28 into the cylinder 23, by the valve 30 and through the port 31 and passage 27 into the position described and illustrated in Figure 2,

and air passes to the pneumatic bell ringer. When the throttle of the locomotive is closed,

the valve 1'7 seats itself, by gravity. Steam or compression in the locomotive cylinder on the forward stroke of the piston enters and passes through the valve chamber 14 and through the port 15 to the cylinder. 6, and action as described above takes place. On the backward stroke of the locomotive piston and/or when no pressure is exerted on the piston 12, air from the main reservoir, acting on the valve 30, seats the same, shutting off the supply of -air-to--the reservoir 2. r The reservoir -2 is so proportioned as to furnish enough head of air pressure for the operation of the pneumatic bell ringer during "the alternate opening and closing of the ball check 30, during such time as the locomotive may be drifting and not working-steam.

When no further pressure is exerted .onthe piston 12, either by live steam 'fromthe throttle or by compression in the loeomotiveoylindef having been reduced to zero through the locomotive and consequently piston stopping, then theair pressure, acting on the valve -,30, .seats the :same ;--and cuts off the air supply zto- 'the reservoir 2.
