JOHN W. BARI'H, OF I ITTSIBURGI-I, PENNSYLVANIA.
SANDING DEVICE.
To all whom it may concern:
Be it known that I, JOHN W. EARTH, a resident of Pittsburgh, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Sanding Devices, of which the following is a specification. 1
This invention relatesto sanding device for motor cars provided with bogie motor trucks.
The object is to provide. for a positive'discharge of the sand in front of the wheels, and also to provide forsu'ch discharge on the rail on curved as well as on a straight track. I I
In street and'interurban railways itis the practice to provide a sand reservoir or receptacle in the car body with a sand discharge pipe projecting downward toward the rail and supplied with a suitable valve.
The usual practice is to have the pipe supported bythe car body, and the sand is discharged by opening the valve, which can be done by means of a lever at themotormans position. This arrangementisnot satisfactory for several reasons. If the sand is not perfectly dry it will not run out oftthe dis- Charge pipe even when the valve is opened, thereby resulting frequently in the failure to sand the track, and furthermore with modern electric cars provided with bogie trucks which are swiveled to the car'body a considerable distance from the carends in order to pass around the sharpcurves of street corners,'.it happens that-a dischargepipe supported onthe car body will not be in position on curves todischarge the sand ontherail.
The object of'the present invention is to provide an arrangement whereby the sanding of the't'rack on curves isiin'sured cars provided with bogie trucks; and also to provide a sanding arrangement whereby'the sand is positively discharged from'the reservoir or receptacle.
The invention comprises the construction and arrangement of parts hereinafter described and claimed. I
In the accompanying drawings Figure 1 is in part a side view and in part avertical section of one end of a car body and truck showing one form of the invention applied thereto; Fig. 2 is ,a sectional view through the connecting T or Y; Fig. 3 is a sectional view through the'truck end member show- Specification of Letters Patent.

ing the connection for the pipes; Fig. 4 is a sectional view of the swivel connection in the pipe; Fig. 5 is an end view of the truck; and Fig. 6 is a side view of a portion of one end offacar and truck showing a modified form of the apparatus.
The carbody 1 may be of the usual or any desired form. Itis mounted at each end upon a bogie motor truck 2 which may be of any type of such trucks. The king pin (or point of swiveling is indicated at 8.. The
sand reservoir or receptacle 1 will be mounted in the car body in any convenient place, preferably underneath the platform 5, being closed by a trap door 6 in the floor of the platform. The discharge from said reservoir is through the opening 7 in the bottom of said reservoir.
The sand is discharged in front of opposite wheels8 through pipes 9 which are secured to the end frame or cross piece 10 of V the truck and have their ends bent downwardly so as to .lie in front of the wheels.
Since these dischar e 1 es are carried b 2D the truck they necessarily move laterally as the truck swivels under the car body on curves, thereby insuring the discharge of the sand onto the rails on curves as well as on the straight track. The inner vends of the pipes 9 are threaded into a modified T or Y 11, to whose third limb is connected thepipe 12 leadingto the sand reservoir. The con- I necting part 11 preferably is provided internally with a V projection 13 which partly divides the inlet orifice of said connection and splits the stream of sand flowing thereinto soas to discharge substantially equal quantities of sand in front of both of the wheels and irrespective of whether the two sides of the truck are on the same level or a slanting track. i The connection from the Y 11 to the sand reservoir may be made in several ways. As shown in Figs. 1 and 5 the pipe 12 connected to the Y 11 extends rearwardly to or v in close proximity to the king pin 3 or point of swiveling of the truck. Here it is connected'to an angle 15 to which is swiveled another angle 16, and to the latter is connected a pipe 17 leading to the discharge orifice 7 of the sand reservoir. This arrangement allows theuse of rigid pipes, since the point of swiveling is substantially co-incident with the king pin.
Fig. '6 shows a modification where the connection from pipe 12 to the discharge pipe 7 of the reservoir is made by means of section of flexible pipe 18, which may be a rubber hose or similar fleXible pipe. YVith this'form it is of course unnecessary to carry the pipe back to or in proximity to the king pm.
The sand is positively discharged by means of the injector action of compressed air or steam. For this purpose the end of a pipe 19 is projected into the discharge pipe 7 in such position that when fluid pressure escapes from pipe 19 it draws the sand out of the reservoir and blows the same through the discharge pipe. Pipe 19 is connected to the usual air brake equipment found on all modern street cars and may be provided with a separate valve or connected to the brake valve 20 which can be opened from the motormans position whenever it is desired to discharge sand onto the track. The discharge pipe itself is not provided with a valve but normally no sand flows out of the same, but only when the air valve 20 is opened. This is due to a curved pipe section or trap 22 between the reservoir and pipe 17.
Preferably the sanding reservoir is provided with a small heater, such as a coil 23 through which electric current can pass continuously or periodically as desired. The heat from this coil serves the two fold purpose of keeping the sand in the reservoir perfectly dry so that it can be readily blown through the discharge pipe, and also serves to heat the floor above the reservolr, thus provlding a warm spot on the floor on which the motorman stands.
The sanding device described insures the positive discharge of the sand onto the track and is not dependent upon the condition of the sand itself, so that failure of sanding is largely prevented. Furthermore the sand is discharged directly in front of the wheels whether the car is running on a curved or on straight track. The arrangement for securing these results is simple, readily applied, and cannot get out of order.
What I claim is:
1. In a sanding device for railway cars, the combination of a car body provided with a plat-form, a bogie truck on which the same is mounted, a sand reservoir on the platform, a discharge pipe secured to the truck and moving laterally with the truck on curves, a flexible pipe connecting the discharge pipe with the discharge outlet in the reservoir, a fluid pressure nozzle projecting into the said discharge pipe, and a valve on the platform for establishing communication between a source of fluid pressure and said nozzle.
2. In a sanding device for railway cars, the combination of a car body, a bogie truck on which the same is mounted, a sand reservoir on the car, a discharge pipe secured to the truck and movable laterally with the latter on curves, a pipe connecting the discharge pipe with the discharge outlet of the reservoir and including vertical parts that swivel on each other and lying in proximity to the axis around which the truck swivels, and a fluid pressure pipe projecting intov the outlet pipe.
3. In a sanding device for railway cars provided with bogie trucks, the combination of a flanged truck frame end piece, pipes secured to the inner face of said end piece and having their ends curved downwardly in front of opposite truck wheels, a three armed connection to which the inner ends of said pipes are connected, a sand reservoir, a pipe connecting said sand reservoir with the third arm of said connection, a fluid pressure nozzle projecting into said connecting pipe, and a valve on the car platform for establishing communication between a supply of fluid pressure and said nozzle.
In testimony whereof, I have hereunto set my hand.
JOHN W. EARTH.
