Application filed June s, 1918. Serial No. 239,005.

To all whom it may concern:

'Be it known that I, JAMES OAssmY, ,a citizen of the United States, and a resident of Chicago, in the county. of Cook and State of Illinois, have invented certain new and.

' useful Improvements in Track-Sanding Devices, of which the. following is a specification. i

This invention relates to a sanding device which is installed on motor and other cars,

for the purpose of sanding the track on truck, as is desired by the operator, and (by modified construction of a movable valve member) to obtain a device by which sand may be discharged in front of the forward wheels in said trucks and also in front of said forward wheels and at the same time in back of the rear wheels of said trucks. Further objects of the invention are to obtain a device operable as above recited by means of which the operator will be advised as to which of the above recited results are being effected by 'him through his manipulation of the handle controlling the device. 7 Further objects are to obtain a device which is not liable to getout of order, or be broken; which is economically-made, and is simple in construction. V I

To those familiar with the operation of electric motor carsprovidedwith two trucks itis known that at times it is desirable to discharge sand in front of the forward pair of the wheels on both trucks and at other times is desirable, to'prevent the car from slipping down a grade, or to move with certainty in backing down said grade, todis-j charge sand to the backof the rear pair of wheels of both trucks.

' I have illustrated a device embodying this invention in the drawing accompanying and forming apart of this specification, in which, i

Figure 1, is a diagrammatic view representing a side elevation of the body, platform, and wheels of a car; showing a device embodying this invention; in elevation installed thereon.

'Fig. 2, is a top plan view of said device.

Fig. 8, is a horizontal section of a valve forming a member of the device, taken on l ne of Fig. 1, and viewed in the direct1on indicated by the arrows.

Fig. fl, is a top plan view of a handle forming an element of the device, with aportion thereof broken away to show a horizontal section.

Fig. 5 'IS a horizontal section of a vertical shaft, with elements thereon which form a part of the device, taken on linev 5-5 of Fig. 1, and viewed in the direction indicated by thearrows.

Fig. 6 is an elevation ofa modified construction of the operating handle of the device. Y

A reference character applied to designate a given part indicates said part throughout the several figures-of the draw ing. wherever the same appears.

X, represents the body of the car. Y, Y represent the platforms of body X.

Z represents sand boxes. Z represent the wheels of a. car. A, A represent vertical shafts which are rotatably mounted on platforms Y, Y, respectively. B are handles which are removably mounted onthe upper end of shafts A, A. B is a strap at the upper end of shaft A. The strap B is pro-. vided with a recess 6, in the construction which is illustrated in Figs. 1 and 4; and with a projection I) having inclined face- 6 in the construction illustrated in Fig. 6. In the construction which is illustrated in Figs. 1 and 4: C represents a tube (see Fig. 4), in recess 6" of handle .B. D, represents a'ball which is contained in tube C. The end 03' of the tube C is turned over onto the ball D so that said ball cannot be forced out of said tube, and E represents a spring which is arranged to yieldingly hold the ballD against the turned end d of said tube. he ball D registers with recess 6 and is forced thereinto by the spring E, when the handle B is turned into position with the valve F fully open. Valve F controls the admission of sand from the several sand boxes Z into the discharge pipes Gr.

In the construction of the several members which are mounted on handle B, as

illustrated in Fig. 6, the member D, pivoted on pin ol, is substituted for ball D, and spring E for spring E.

' The construction of valve F which I pref erably employ is represented in Fig. 3, in which f'represents the shell or casing of the valve; F a pivotally mounted valve member turning on pivot f" and f a spring which yieldingly holds said valve member in position to close the apertureig, Valves F are attached between two parts of pipesG so that when the valve member- F closes aperture said valve member obstructs the passage ofsand from receptacleZ'through said pipe to the discharge ,end thereof. 9 .7

ment of the valvemember F is suflicient tosuccessively bring said aperture 9' and aperture g over said aperture g.

r VVhen valve member F is tur'ned on pivot f so that aperture 9 therein registers wlth aperture .9 in .the lower face of the valve casing sand is delivered from receptacle Z, through the pipe G in front of the forward wheel of each trucld ofthe car, the size of the stream thereof being determined by the angular movement of the valve member F. .When aperture 9 is provided in member F. and said member' is given its greatest possible angular movement, sand will be discharged in front of the forward wheels of each truck and also in back of the rear wheels of each truck. l Themanner in which this movement of lever produces correspondin movement of valve member F, as hereinbefore described,

is hereinafter set forth. V

To permit sand to be discharged through the casing f of the valve F the-valve memher Fis pivotallylmoved to bring the aperture g (or g), to register with aperture 9. The turning of-the valve. member F is effected by means of links H, which are, respectively, engaged at one end with arm or lever I and at the other end with the respec- K, KK K are rocking shafts secured to the under side of body X, by any suitable means, L, L, L L 'are levers which i are rigidly'secured to corresponding shafts of the K series. The several levers J, J, J J 3 are'also rigidly secured to corresponding ones of the rockingshafts K, K,"K K Said shafts are rocked by means of the connections of the M series about tobe described. N,':N, are chain wheels on shaft A rigidly? attached thereto. N N are chain wheels which are rigidly attached together and are 'loosely mounted: on shaft A. N

i and N are chain wheels rigidly mounted on shaft A. N N are chain wheels which are. rigidly connected together and loosely mounted on shaft A. A n are abutments which are rigidly secured to, or are integral 7 with, the chain wheels N and N and n are like abutments which are rigidly secured to orare integral with the chain wheels N and N M is a connection which extends from the wheel N to the lower end *of lever .K. M represents. a connection which extends from the 'wheelN to the upper end of lever L M a connection which extendsfrom wheel N to the upper end of the lever L and M* a connection which extends from wheel N to the lower end of lever L M a connection which extends from wheel N to the lower end of lever Li; M a con,- nection which extends from wheel N to the upper end of lever L; M a connection which extends from wheel N 7 to the upper end of into engagement or contact, as suggested,

the movement of the chain wheels N, N (or N N will not produce movement of chain wheels 'N N (or N 6 N but'after said engagement is made continued movement of the shaft A (or A) and the wheels N, N (or N N will move the wheels N N (or N N along therewith. The ball D, hereinbefore described, enters .the recess B on strap B, as hereinbefore stated, when the forward movement of the abutment n as last above 7 described, is sufficient tobring the forward faces thereof into contact with the rear faces of the abutments ml. Notice isthereby given, by the ball D entering said recess 6, thatsaidfcontact had been made and that any further movement of the handle 'Bwill also move chain wheels N N (or N N). 1 Such further movement can be made as the ball is yieldingly held in the recess 6; but when said movement is made, knowledge of the same is given by the said ball, as it is'forced out'of said recess:

In the construction having the" members mounted on handle B which 'is'illustrated in Fig; 6, the end of the member D which is adjacent thereto abuts againstithe a'buts ment 6', when the hereinbefore described forward movement of abutments n bringthe forw'ardfaces thereof into contact with the rear faces of abutments at. No further movement of handle B can then be made until theend of said memberD which is over the handleB-isdepressed to raise the other end thereof up so it may pass over abutment b. When it is desired-"to sand the-track" to the rear of-the rear wheels of the-trucks of the car, said member D is defurther moved to pressed and handle B is (or N move chain wheels N and N and N By the said last above described construction a positive act (to wit, depressing one end of member D) is required before sand can be discharged on the track to the rear of the rear wheels of the trucks and hence when aperture 9 in member F is used I prefer this construction.

I claim l. A sanding device comprising vertical shafts rotatably mounted on platforms, wheels rigidly mounted on said shafts adjacent to the lower ends thereof, and additional wheels loosely mounted on said shafts, means connecting the rigidly mounted wheels to the loosely mounted ones so that upon the turning of said rigidly mounted wheels a measured angular distance further turning thereof will also turn said loosely mounted wheels, in combination with Valves and connections between said wheels and said valves.

2. A sanding device comprising vertical shafts rotatably mounted on platforms, a handle adapted to be attached to said shafts, and said shafts respectively provided with means to indicate a measured angular movement of said handle, wheels rigidly mounted on said shafts adjacent to the lower ends thereof, and additional wheels loosely mounted on said shafts, means connecting the rigidly mounted wheels to the loosely mounted ones so that upon the turning of said rigidly mounted wheels said measured angular distance further turning thereof will also turn said loosely mounted wheels, in combination with valves and connections between said wheels and said valves.

3. A sanding device comprising vertical shafts rotatably mounted on platforms, bearings for the upper ends of said shafts adapted to permit angular movement thereof, a handle adapted to be attached to said shafts and said handle provided with a movable member and a spring interposed between said movable member and said handle to yieldingly hold said movable member in position to indicate a measured angular movement of said handle, wheels rigidly mounted on said shafts adjacent to the lower ends thereof, and additional wheels loosely mounted on said shafts, abutments on the rigidly mounted wheels and abutments on the loosely mounted ones, said abutments positioned so that upon the turning of said handle said measured angular distance fur ther turning thereof will bring said abutments .into contact and turn said loosely mounted wheels, in combination with valves and connections between said wheels and said valves.
