JAMES M. BISING, OF JERSEY CITY, NEW JERSEY, ASSIGNOR TO vAIVIEIRIIGAN ROAD MACHINERY COMPANY, RATION OF DELAWARE.

INC., OF KENNETT SQUARE, PENNSYLVANIA, A CORPO- SNOWPLOW.

Application led. April 23, 1,926.' Serial' No. 104,012.

AMy invention relates to snow plows and more particularly to snow plows of the type adapted for ready attachment to motor trucks. Y 4 j Heretofore various forms of. snow plows, including 'blade and V type plows, have been adapted for attachment to motor` trucks and such plows'have proved of substantial value in use in connection with the removal of snow from city streets and in maintaining highways open.

Such plows are of distinct advantage beany special apparatus for their propulsion, being readily attached and detached from any one of theusual types of motor trucks.

In the useof such plows, speed is of paramount importance, especially in the work f maintaining highways open, which is accomplished during snow falls and the value of each plow depends upon the distance itmay be made to cover efiiciently. f y

The plows of the type indicated, as heretofore produced, while possessing substantial advantages, are not capable of any great speed in operation nor of any substantial adaptability to varying conditions, such as varying rates of snow fall, types of roads, etc., and therefor, fall far short-of filling the requirements of the present increased motor traffic necessitating the maintenance of open highways and removal of snow from city streets.

Now it is the objectv of my invention toprovide a plow of the type and for t-he purpose indicated, which will beof novel and.

greatly improved structure and which will have the capacity for operation at relatively high speed and a ready adaptability to varying conditions of service.

y Having now indicated, in a general way,

Fig. 3, is a View of a detail of construc-` tion. j

Fig. 4, is a section on line 4 4 of Figure 2.

Fig. 5, is a front Vviewof hoisting apparatus.

Fig. 6, is a view of a detail.

Fig. V7, is a side View showing a modification of my invention.

Fig. 8, is a perspective view of the plow shown in Fig. '7.

Referring now more particularly to Figures 1-6 inclusive, a indicates a motor truck to the front axle b of' which are clamped brackets c to which are pivotally secured,

by means of horizontally extending pins (l,

lthe ends of the side members of a framee,

move about both transverse and longitudinal plvots andmay conform to the surface over which it is propelled. Beneath the plow nose 1s a runner y.

From the endsy of the sidesv of the plow nose f extend wings lo which form a continuation of the sides of the nose. The inner ends ofthe wings extend behind. the ends of the sides of'the'nose and are pivotally secured thereto through the medium of removable'pins Z, which are passed through brackets m and u secured to the sides of the nose and the wings respectively. Thus it will be noted that the wings may be readily removed or attached to the nose and that they may be adjusted at angles to the sides of the nose. VIn order to maintain the wings c in adjusted position and to brace them., struts o are pivotally attached at one end to brackets p secured adjacent the full ends of the wings and are provided with a series of holes g adjacent the full ends, which ends are adapted to pass through and be' sup-A ported by brackets r secured beneathl the side members of the frame e.

through anyone. of' the lho es,v g and lsuitable holes formed in the -side members of the The full ends are releas'ably securedv to the-frame and bracketsV -r by means of pins's ada tedto'jbe. passed frame and brackets. Beneath the wings adjacent their full ends are positioned runners t. l

Midway of theupper edges of the wings lq are secured eyes u to which are attached, through the medium of springs o, which may be maintained under a set tension, the ends of a chain The chain passes over a sheave y, the supporting frame .e of which is engaged by one end of a chain 2. The sides of the sheave frame a are provided with holes for-the passage of a pin 3, which when passed through the casing, as shown in Figure 6, engages the chain and acts to lock the sheave y, and prevent running of the chain Thus the ch-ain .fr may be ad? justed so as -to have a greater length of chain between the sheave and one of the wings .than between the sheave and the other wing and enable the plow to be maintained even during raising or lowering.

The plow nose f is provided with an eye 23 through which is adapted to be passed one end of a chain the other end of which is secured to an extension vs of the sheave casing a. The chain is secured to the eye 23 by engagement ofa hook 24 in the end of thechain with an intermediate portion of -the chain, as shown in Figure 1. Thusthe length of the chain from the sheave to the nose may be readily v-aried, permitting the nose to be adjusted upwardly or downwardly with or independently of the wings. y

Secured to the forward end of the 'frame of the truck a are a pair of brackets 4 to which are'adapted to be secured the ends of an A frame. 5, each provided with a series I- of holes 6 through any one of vwhich and a bracket is passed a pin 7. A cross member' 8, provided with eyes 9 at its ends, is securedto the frame 5l by means of U bolts passing through holes 10 in the cross member, enabling it to be laterally adjusted. Chains 11 are fastened to the eyes 9 of the cross member and to, for example, running board brackets 12 of the truck and serve to brace the frame 5. Beneath the cross member 8 is Secured a sheave 13 beneath which passes chain 2.

Secured' to the top of the A frame 5 is a casing 14 within which is an internal gear 15 within which meshes asmall pinion 16, mounted on ay shaft 17 which extends throughv the rear of the casing and is connected through a sliding engagement with a universal joint 18 to a shaft 19,.the rear end of which is supported by a bracket 20,

mounted on the truck dash, and is provided -with a hand wheel 21 for turning. The internal gear 15 is-mounted' on a shaft 22 which serves also to support a sprocket 23 over which; passes the chain 2. It will be noted that'iif the pinion 16 be rotated by rotation 'of hand wheel 21, to which it is connected through shafts 17 and 19, the internal gear 15 and' spro ket 22 will be rotated and the chain 2 dran in or let out over the sprocket witlr the result that the frame e and attached plow may be raised up about the pivots c and again lowered. The ratio between the pinion 16 and the internal gear 15 is such that very little effort is required on hand wheel 21 in the raising or lowering/of the plow. It will also now. be noted that if in the raising of the plow it tends to twist or one of the wings tends to sag below the other, such tendency may be compensated for by varying the lengths of the portions of chain m between the sheave y and the Awings respectively, which may be readily accomplished by adjusting the chain m on the sheave and then locking the sheave by means of the pin 3, as described.

The raising and lowering of the plow through the medium of' pinion-16, though requiring very little effort on hand wheel 21, is relatively slow. In order to provide a more rapid means for raising and lowering the'plow, for use when relative rapidity of manipulation is desirable, a second and larger pinion 24 is mounted, within .the

casinof 14 in mesh with internal gear 15 on -and through the joint to shaft 19 and hand wheel 21. The larger pinion 24 it will be noted,- though requiring slightlyV greater effort on hand wheel 21, enables greater speed in lifting and lowerin of the plow.

Referring now to Figures and 8, the V shaped plow nose 25'is secured to a frame e attachedthrough transversely extending pins el to brackets c clamped to the front Vaxle of the truck a. The plow 25 may be substantially similar in construction to the plowl f except that its sides are of substan' tial length. 7llfings 26 are arranged telescopically .with the sides of the -plow 25 in such a manner as to enable them respectively to be extended varying distances from the ends of the sides of the plow or to be telescoped withthe sides so that they will have a negligible extension.

The wings adjacent their outer ends are provided with brackets p adapted for .the passage of pins as mediums for pivotally securing struts o to the wings. The struts 0 The ends of a chainI m are secured to the wings26 through springs 'v'. The chain passes over a sheave y', adapted to be locked by means of a pin 3', and to the casing e of which is secured one end of .a cable 27.

Secured to the forward end of the truck frame is a frame 28,' suitably braced by means of braces 29, and having journalled in its upper end a shaft 30, upon which is mounted a drum, around which cable 27 passes, and a sprocket 31 connected by a chain 32 with a sprocket 33 on a shaft 34, journalled in frame 28 below shaft 30 and carrying a gear 35. In mesh with gear 35 is a worm 36 on one end of a suitably supported shaft 37, on the other end of which is a hand whcel`38.

The cable 27, passing around the drum on shaft 30, extends through the truck cab 39 and over a sheave 40, mounted in a bracket 4l secured to the rear of the cab. A weight 42, of somewhat less than the weight of the plow 25, wings 26 and frame e', is secured to the end of cable 27. It will be noted that the weight 42 acts to counterbalance the plow assembly and greatly reduces the effort required, on hand wheel 38, to rotate gear 35 on shaft 34 and through chain 32, sprockets 33- and 3l to rotate shaft 30 and the sheave thereon, over which cable 27 passes, to raise and lower the plow.

It will now be noted that in accordance with my invention a plow of great eiiciency and adaptability is provided and one which is capable of ready adjustability and high speed in service.

It will also be noted that the plow in accordance with my invention is capable of adjustability for the exigcncies of varying types of service and various types and widths of roads without any sacrifice of eiciency.

It will be understood that in describing Athe specific embodiment of my invention shown in Figures 1-6 and the modification shown in Figures 7 and 8, I do not intend that my invention shall be limited to specific details of construction, and it will be further understood that when in the specification and claims I referto a motor truck, that I intend to include any other vehicular means for propelling the plow, as for example, a tractor.
