SANDING DEVICE FOR TRACTION WHEELS.

tion' or traction'between the driving wheels and the track or roadway.

Among the objects of the invention therefore is to provide means carried by the vehicle and at all times under convenient and reliable control by the motorman or driver whereby a friction medium such as sand may be distributed upon or applied to the roadwa or track for engagement by the traction W eels so that not only may the wheels be given the necessary frlction forthe purpose of propulsion of the vehicle,

but also, especially in connection with automobiles, to provide such safeguards as will prevent the dangerous and oftim'es diastrous. skidding of the vehicles.

Another object of the invention is toprovide a mieans for applying or distributing sand or the like to the roadway which includes a charge of sand supplied in the. receptacle which may be applied to or removed from the vehicle at will, and where-. in the sand may be supplied and retained for an indefinite length of time in such perfectly dry condition as to be sure. to flow freel from the receptacle to'the point of. application desired. To this end the charge of sand or the like is supplied in a form of a cartridgev comprising an air and water tight shell or container of either a cheap discardable nature or one which may be' of a more substantial structure and refillable, but in all cases from which the sand will'be delivered under the control of the operator or as conditions may require as a result of the opening of the shell either by the pro-' vision of a movable part thereof or by the rupture of a portion of the shell structure.

Another object of the invention. is to provide a lurality of sand cartridges-arranged prefera ly in' a series so as to present the a casing of any suitable structure,

cartridges singly and in succession into position for the delivery of the contents as desired.

W1th thev foregoing and other objects in view the invention consists in the arrangement and combination of parts hereinafter descr bed and claimed, and while the invent1on is not restricted to the exact details of constructlon disclosed or suggested herein, still for thepurpose of illustrating a practical embodiment thereof reference is had to the accompanying drawings, in which hke reference characters designate the same parts 1n the several views, and in wh1ch- Flgure 1 is a vertical sectional view of tasandmg apparatus embodying my invenion.

Referring. now more specifically to the drawings as a practical embodiment of the lnventlon, but without unnecessary limitatlo'n tot-he specific mechanism illustrated, I indicate at 10 a supporting member such as the runnlng board of an automobile or a portion of a car frame or body located just 111' advance of a traction wheel 11 whose mud-guard is indicated at 12. '13 indicates but preferably of such a nature as to possess the requisite strength for protection of the traction medium to be delivered therefrom.

view of one of thecheck Said casing includes a door or lid 14 shown side of the running as accessible at the board and which when opened or removed to the entire interior of the casing. The casing as shown is in the nature of a cylindrical drum, in the center of which is journaled a carrier comrising a shaft 15, the main support for the shaft being a bearing 16 constituting a the end wall of the casing. On the door however is a central cone bearing 17 which in (ac-oper ion with the end of medium unit indicated as in the nature of a the shaft serves as a centering device and auxiliary support therefor when the door is shut.

As above premised one of the principal features of this invention is the friction segmental cartridge 18 which may be of cheap paper or the like and discardable after being once used, or may beof a more substantial or permanent nature but provided along one side with a cheap frangible panel 19 of any suitable form to meet the requirements. If desired the advancing edge portion of the panel may be provided with a pull member 20 such as a wire whereby to insure the complete and effective rupture of the panel and the full opening of the delivery mouth 21 of the cartridge. 1 show an endless series comprising eight of these cartridges adapted to be brought into delivery position in succession. Obviously, however, any other number might be employed and the cartridges mlght be ar-' ranged in any other desired manner for successive delivery.

The means indicated for supporting and controlling the cartridges comprises radial walls 22 fitted upon the shaft 15 within the casing 13, each wall being provided with two flanges 23. The flanges are so designed as to embrace or engage over the edge portions of the cartridges to hold the same steady and from movement with respect to the casing. The portion of each cartridge that is not embraced by the walls and flanges is the portion farthest from the axis of the shaft 15, and hence is the portion that sweeps closest to the inner surface of the casing during the rotation of the'carrier. When the door 14 is opened or removed from the casing the operator has free access to the carrier and the filled cartridges may be put into place, with the frangible portion or panel 19 adjacent to the wall of the casing. The cartridges may all be put into place without movement of the. carrier or if desired in some cases the cartridges may all be inserted at about the same place with a step by step movement or rotation of the carrier, depending upon the size, form or location of the casing and the convenience afforded by t-hedoor or lid.

At the bottom of the casing is a delivery spout 27 preferably so designed as to provide for the delivery of the friction medium in the direction or condition most favorable for the particular use or the nature of the vehicle intended. As shown herein and as designed especially for an automobile, the delivery spout 27 has considerable length transversely of the path of the wheel and with the .mouth portion somewhat restricted so as to cause the scattering or spreading of the sand S. The front side of the spout extends downward beyond the level of the rear side, whereby the outlet is guarded from mud or other extraneous matter that might tend to clog it. For convenience the term sand will be employed hereinafter with reference to the friction medium, but it will be understood that any other suitable medium such as salt, cinders, ashes, or the like, might be used.

Any suitable means may be provided, preferably under manual control of the driver or operator, for causing the movement of the cartridges so as to bring them' successively or step by step into delivering position. To this end I show a pawl 28 mounted upon a pivot 29 connected to an actuating lever or arm 30 and oscillatable around the axis of the shaft 15, the arm having attached thereto a pull rod 3l or its equivalent whereby the driver of the machine has control of the carrier and cartridges. The pawl co-operates with a ratchet wheel 32 having as many teeth as there are pockets or spaces in the carrier. The-normal position of the actuating means is indicated in Fig. 1 at which time one of the cartridges is located directly above the de livery spout. A spring 30 may co-operate with the arm 30 to return it to normal position. v

Fixed upon the inner surface of the cylindrical wall of the casing 13 is an opener shown in the form of hooks 33. These are arranged at any convenient points in front of and above the delivery mouth. The point of each'hook extends upward in position to. receive the wire loop of the next cartridge during the step by step movement or rotation of the carrier as a result of the forward pull on. the actuator rod 31. The throw of the rod corresponds to the length of a tooth of the ratchet wheel 32, and hence for each forward-reciprocation of the actuator rod the carrier will be moved through a distance equal to the distance between centers of adjacent cartridges. Hence, the cartridge located adjacent to or next above the opener 33 will be carried downward and rearward past the opener. The action as indicated in Fig. 1 will cause the frangible panel 19 of such cartridge to be ruptured as a result of its wire being engaged by the hooks, and while the cartridge is carried onward toward its delivering position over the spout 27 the hooks will cause the complete rupture and withdrawal of the panel 19 and a clearing of the mouth 21, and thus the sand will be delivered directly and freely from this cartridge to the spout and thence will be scattered broadcast upon the track or road in front of the traction wheel. It must be borne in mind that in all sanding devices for traction vehicles the condition of the sand with respect to moisture and possible freezing is of paramount importance. Various attem satisfactory.

. thus insuring that. the. sand will be kept for-an indefinite length of time free from moisture. After the carrier is supplied with carfor operation and inan emergenc 1 actuator rod 31 be reciprocatedas escribed the cartridges maybe emptied in succession through the delivery spout 27. -'Ordinarily one or two of the cartridges will be sufiicient to pass a dangerous spot, but if necessary all of the cartridges in the series may toward the free ends of the springs and.

be emptied in rapid succession.

It will be noted that any empty cartridge in the carrier will rise on the rear side of the supporting shaft so that any filled carthe carrier. Undesiredrotation, however, of the carrier will be prevented by reason of some suitable check,

such as a series of springs 2a secured upon J the inner face of the door 14, and eachhaving a notch- 25 in which is normally engaged a rib 26 formed on the outer edge of the cartridge. The cartridges are movable hencethey are easily slipped from'the normal holding position indicated. At any convenient time the empty shells may be withdrawn and fresh filledj cartridges put in their places, and the emptyshells may be either discarded or reused-according to the material from which they are made. At

any time the door '14 is opened the number of wires foundimpaled on the hooks 33 will indicate the number of empty cartridges.
