Application filed January 13, 1916. Serial No. 71,960, and useful Improvements in Sand-Feeding Apparatus, of which the following is a specification. This invention has particular relation to sand feeding apparatus and as its primary object it contemplates the provision of an improved device of this character that is especially designed to be used in connection with automobiles and other motor vehicles: and which will apply the sand. to the ground so as to prevent lateral as well as the longitudinal skidding of the machine. Another object of the invention is to provide improved means for efficiently feeding the sand to the various distributing nozzles in order that a uniform flow may be obtained at all times, when desired, and to obviate stoppage of the sand due to the clogging of the conductingpipes. A further object of myinvention is to provide a device of the type in question that is extremely simple in construction, strong and durable, and highly practical from both the standpoint of the manufacturer and the standpoint of the user; and which, it is belicvcd. may be manufactured at a comparatively low cost. Various other objects and advantages will become apparent during the continuance of the following description. These objects are accomplished by such means as are shown in their preferred form in the accon'ipanying drawings, described in the following specification and then more specifically pointed out in the appended claim. in the accbmpanyiug drawings wherein like characters designate like parts throughout the several views: Figure 1 1s a viewin top plan showing my invention as applied to an automobile of substantially the conventional form, the automobile body being shown in dotted lines; Fig. 2 is a View in longitudinal section of one of the distributing chambers; Fig. 3 isa View of the sand dome or reservoir; and Fig. 4 is a diagram= matic view illustrating the relative position of the distributing nozzle and the respective wheel. in reducing 'my invention to practice, it provide a dome or reservoir 10 toreceive Specification of Letters lfaten't.

Upon its underside, the dome 10 is provided with a series of individual chutes 11 which maybe in turn connected with the several feeding pipes 12, 13-and 14 respectivelyil Suitable distributing'chambers may be arranged in proximity to each of the drive wheels of the machine while a single distributing chamber may be used in com mon in connection with thetront wheels thereof. M In Fig.1, the several distributing chainhere are designated by the numerals 1o, 16, and 17, respectively; however, in View of the fact that they are all of practically the same construction, only'one will. be de scribed in detail. This distributing chain" her is shown in section in Fig. 2. The distributing chamber above referred to, consists of a tubular body structure 18 that may be formed of any suitable or sirable material, and which is preferablyconstricted slightly toward one end to form an annular offset flange 19. At its other end, the'r'espective casing ma be formed so as to receive a plu 20, the latter having a nozzle member 525?. The casing 18 is further provided with an inlet opening 23 about which is arranged a connecting collar 24, the inlet opening or tending at a substantially right angle with respect to the general extent of the casing, in its preferred embodiment. The lower ends of the several feeding pipes 12, 13 and 14, as above referred to, may be provided with suitable flanges 25 whereby they-may be readily connected with the dollar 24 of the several distributing casings.- Further-- more, in order to facilitate a more secure connection between the feed pipe and'the hill casings, it has been found desirab e, under certain conditions, to interpose a washeror take-up member 25 between the flange and the collar. This take-up member also-serves to rotatably support the flange 25 as clearly shown in Fig. 3. Adjacent thepassag'e 21, the plug 20 is provided with an annular odset 26 to which may be connected one end of a conducting tube 27. 1 preferably pro-- vide a conducting tube for each of the dis tributing chambers, such as indicated by the. numerals 27, 28, and 29 which in turn con meets with an air container or other genera tive source, as at 30, by way of a suitablycon ice , trolled regulatingvalve 31. Consequently, ' spectively, are connected with the several cas- 1o jerly distributed about the ings' 15, 16 and 17 such ascleajrly shown in Fig. 1, and which in turn carry suitable nozzles 36 by which the sand may bepropground in ad- .vanceof the wheels, The pipes-32 apd .33 may bearranged so that the nozzles 369cmried thereby direct thes'and onto tlie groundslightly in advance of the sidewheels and by reason of the special; configuration of the nozzles, the sand willbe spread in a fanshape manner about. the ground. "Ilhis, as "" will be apparent, will efiectually-prevent longitudinal skidding thereof; On the other lateral skidding. of the wheels as well as hand, the pipes 34 and 35 which project from the casings 17 are arranged so that the sand ejected therefrom will be'placed side thereof whereby skidding thereof will f Consequently, in advance of the front' wheels and to each be effectually iprevented, irrespective of the angle at which the wheels may be turned. :Skidding generally occurs when the ma chine'is rounding a curve and this method of distributing-the sand is thought to be especially eifectual in this connection. Although any desirable means may be employed by which the operator can.c0ntrol the yalve above referred to, it is pointed out that this may be controlled'by a switch in proximity to the operators post of duty. one pole of the source of power 39. The other conductor 38 is in turn connected with a switch pole 40 while another conductor 41 connects with the other pole of the source of power 39 and the switch lever 42. Conse-- quently, by closing the switch lever in the usual manner the valve 31 may be opened or closed such asthe case will be. ' Under normal conditions, the sand from action of gravity intothe dome 10'is. fed by the respective distributing chambers, as 3 :shown in Fig. .2, so as tocompletely cover I the appendedlclaim.' , conical body, the nozzle; member 22, therefore, when the air is introduced through the nozzle member, the sand in the forward or rear end of the chamber, such as the case may be, will be forced directly through the respective 1 distributing pipes, while, at the same time vention will be readily understood "and, therefore,. further detail description is .deemed unnecessary. In reducing my invention to practice I find that the form referred to herein as the most practical and preferred embodiment is the most efiicient, but realizing that certain bined conditions will necessarily vary in concurrence with the adoption of my device, I desire to emphasize the fact that various minor changes inthe details of c'onstructionand in the. proportion of partsmay be resorted to when required without sacrificing any-of the advantages of my invention as defined in Having thus ful ly described the invention, what I claim as new and deslre to secure by Letters Patent'is-z- In-a sand-feeding apparatus, a distributing chamber comprising'a hollow elongated an'intake communicating with said body at a point adjacent to and spaced open to the smaller end of said body, a removable plug fitting the inner Wall of said I CHARLES P.
