- V comotive-Whistles, of which the following is a specification, reference being bad to the accompanying drawings, forming a part thereof.

Figure 1 is a rear end-elevation, partly in section, of a locomotive-engine withmy inveution attached. Fig. 2 is a side elevation and section. of a portion of a locomotiveengine.

. r Fig. 3 is a plan view of horizontal levers connecting the vertical shaft 0 with mechanism actuated by the reciprocal levers S S. Fig. 4

is a view of a step to be affixed to the railroadtrack. Fig.5 is a front elevation of said step.

Figs. 6, 7, t and Sare enlarged views of the mechanism in detail.

The object of my invention is toca-use the automatic blowing of locomotive-whistles at railroad-crossings and. other pointswhere by law it is required to blow them, and is especially valuable in case of accidents, as settling all question or don-ht as to the fact of blowing.

Fig. 1 is a rear elevation and section of the cab of a locomotive-engine shown in myinvention.

A is the whistle, and a 'is the rod connect;

ing the whistle-lever with the lever a, attached,

to shaft B byset-screw a.

B is the horizontal shaft, attached to the front side of the cab by the stands H.

O is the vertical shaft, passing in front of the left-hand corner of the boiler down through the floor of the cab.

D is the lever loose on shaft B, for blowing the whistle by hand.

E is the lever fastened to the shaft B by set-screw e, and to the side of said lever E is fastened the rod 2. 0 passes through the holef in lever F.

is a spring around 0, which gives an elasticJconnection between levers E and F.

F is a loose leveron shaft B, having inits outer end the hole f.

G is a leverfastened to the upper end of shaft 0 by the set-screw g. The lever G presses against the lever F, means of opening the whistle.

dis a collar fastened to shaft B by set-screw d, and d has a finger, d against which lever D bears or presses when blowing the whistle by hand.

affording the H H are the stands-forming bearings for the shaft B. if

H is a stand forming bearing for upper end of shaft 0.

H H are the stands carrying thebearings for levers S S and shaft P.

H is a shaft on which the levers S S swing.

I l are the inclined levers, against which the levers S S, respectively, strike alternately to operate my invention. 7

P1 are pieces of plank to which the incline levers I I are attached by the hinges i t.

'2 is a bolt connecting the inner ends of l I.

i is an inverted cylinder passing over the cylinder i and containing the spring i is a bolt fastening cylinder it to the plank 1 L is a link connecting levers T T by bolts 1 l.

N is the stand forming bearing for lower end of shaft 0.

P is an upright shaft having the fingersp'p near itslowerend, which extend horizontally from the shaft P, on opposite sides thereof, but not in a line exactly transverse to the engine, but symmetrically at a small angle in ad- Vance of such a line, as shown in Fig. 3, and to the upper end is fastened the lever T.

p is a bearing for shaftP.

R is a friction-bearing near the upper end of shaft P. r is the cap of said hearing, which is tightened by boltsr r.

S S are .levers swinging on shaft H and having at their upper extremity fingers s s.

T is a lever fastened near the lower extrem ity of shaft 0 by set-screw f.

lever I, arranged upon the track, and is by it swung rearward. Its pin 8 strikes the finger p upon the shaft 1?, pushing it forward and rotating shaft P in such direction as to draw the rod L rearward. This rotates shaft (J, whose arm G, acting upon the lever F;.pushes with an elastic pressure (due to the spring 0 the lever E rearward, so rotating the shaft B, and

through its connections blows the whistle.

The latter continues blowing until, the engine advancing a suitable distance, the lever S encounters asecond incline, I, and, aoting upon the opposite finger, p of shaft P, reverses the above-described movements and shuts off the whistle.

It is obvious that the fingers pp must be arranged on shaft P as above described in order that as S acts upon it S may not be acted upon by it in a reverse direction, and the converse.

I claim as my invention- 1. The step shown in Fig. 4, which may be made of bandiron and affixed to the railroad track between the rails and fastened to wood planks, in combination with the reciprocal levers S S, as shown in Fig. 6, and the loose lever F insaidfigure, operated by the lever G against the resisting-spring f in Fig. 2 to move the lever E, as and for the purpose set forth.

2. The combination of the levers S S with the shaft P, having'fingersp p, and mechanism connecting with the whistle for operating the same automatically, substantially as specified. Y

3. The loose lever F, in combination with'the lever G, the resisting-spring f, lever E, and

the shaft B and its connections with the whistle, as set forth, to provide an elastic leverage on the horizontal shaft B, as and for the purpose set forth.
