Myinvention relatesto snow plowsland more particularly to snow plowsof the type adapted to be propelled by a tractor or motor truck. e y

Heretoforeit has been well knownto provide snow plows mounted onor connected to a frameadapted to .be secured to a motor truck axle in such afmanner as 'to enable the truck to push the plow ahead of it., It is also well known to mount or secure a plow in association with a Yframe adapted to receive a tractor and connected to the tractor in such a manner as to enable the tractor to propel the plow. Y

Structures such as those .indicated have proved to be of great advantage in clearing snow from highways and city streets and they are vextensively used in those cities and sections of the countrywhich are subject "to substantial snow fallsl As a result ofthe extensive use of such plows, however, various defects havebe'en observed and various modiiications made to correct them.' However, it may be observed that such plows, land more particularly the V type plow, are frequently damaged yby obstructions as, for example, ice, and are relatively ineiiicient in snow of substantial depth due to the fact that they are positively propelled by the truck or tractorto which they are attached. j j j j I Nowit is .the .obj-ect of my. inventionto provide a snow plow of the type indicated, which will be propelled through the medium of resilient means, thus 'enablingvthe plow to more eectively act in heavy orjdecp snow andat'the same time avoid injury on'the striking of an obstruction'. Further objects of my invention are to provide a novel and highly effective and vdurable structure and at.

the same time a structure ot'simplicity and economy in manufacture.

Having now indicated, in a general way,

the nature and purpose of my invention,v l

f will proceed to adetailed description thereof with reference to the accompanying drawinffs in which there is illustrated a preferred :D s I n embodiment and in which Figue l, iS 2L Plan vewof a snow Plow of 'the V type embodying my invention.

Figure 2, is a side view of the plow shown in Figure vl partly broken away to show details of construction.

Figure 3,'is a .view from the rear and partly in section, ofthe plowishowninlligures Y, In: the lseveral figures the plow is formed by` a pair ot angular extending blades', a internally braced by means of a ramefcom- Y posed of angle members @extending transversely between the Vblad-es adjacent their rear ends, vertical angle members 0, to which the cross'lmembers are secured, and angle members d, secured together at the front of thefplow and to the upper cross member I),

through plates e. A barf-extends fromthe v bers'j cross braced adjacenttheir Vends ,by

memberslais adapted to be pivotally secured to a suitable fitting mounted on the front axle of' amotor truck, indicated by line Zv between .wheels mi, or to thefront of a frame such as is usually utilized in connection with tractor propelled plows;

On the bar f are mounted alppair of spaced *A guides n and l0, Ain whichv is adapted to slide one end of a rod p upon the other end of which isV positioned a heavy, coil spring g. The spring isretained on the rodvunder tension between a washer y which bears against` the guide ol and a `washer ,1' which bears against a collar s secured to the'pin.

Secured tothe rod p is a bracket 4ton the top of which is provided a journal for a pin u whichV extends therethrough and "through the ends of thefframe side members j.

A' rod o extends vertically through the cross members band through a` slot fwV in a plate w secured to the frame members j. The :rod is maintained inplace by pins ,2. l

It will now be observed t-hatif the frame members y' be connected to propelling means as a motor truck or tractor, and it will be understood that for the purposes of my in j vention a motor truckor tractor are equivalent, that the plow will'be propelled through the medium of the spring g, which acts be.

tween the rod p, which vthroughthe bracket t and pin u is secured tothe frame members.v j, and the bracket o which is mounted on thel n n nu apex ot' ,theV plow.

bar f secured to the plow. The rod o as will be observed preventslateral movementv of the plow.` It will be also observed that the rod p is turnable in guides n ando thus permittingfthe plow to retain a level irrespective ot the frame members j, and since the pin uis turnable in thejournal in bracket t, the nose Aof lthe plow may liit to clear ordinary obstructions'.

It will be noted that due to the propulsion of the plow through the medium of the spring g shock on the plow and propelling ineansis substantially reduced and that due to t-he substantially universalconnection between trame members and the bar f the f tio the other ends ot the horizontal bars, up-

per and lowerv cross bars. connected to the lVertical bars, and al longitudinal bar connected to the center of the lower crossba'r and tothe two lower horizontal bars at the 2. `A snowplow of the V type -liavin'g two blades connected to each other at the apex y Vot' the plow, a supporting frame comprising an'upper anda lower set of horizontal bars connected to the blades,jthe bars et each set lbeing connected to each other at one end at the apex` ofthe plow, vertical bars connected to the other ends ot" the horizontal bars, cross upper, and lower bars connected to the-'Vertical bars', a longitudinally, extending'bar connected to thelower cross bar and the apex of thed blades, and means. on said l'ongitiidinally extending bar for resiliently connecting a plow pushingfelernent thereto.

' 3; A snow plow of the Vtype having two blades connected to eachother at tl'ie apex oi the plow, a supporting' frame comprising an'upper anda lower set ot horizontal bars connected to. the blades, `the bars ot' each set being 'connected to each otherat `one end at the apex ot the plow, vertical bars connected to the other endel of thev horizontal bars, upper and lower cross bars` connected to the Vertical bars, a longitudinally extending vbar connectedto the lower cross bar and the apex of the blades, a runner connected to the longitudinally extending` bar, a shoe connected to each end of the lower cross bar,

and resilient means on said longitudinally extending .bar for connecting a plow` pushing element thereto.

Ll. A snow plow ot the V type having tw@ bars, and a pushing element pivotallyk cona nected to the plow between the apex thereof and the vertical rod, said pushing element extending to the rear ot the plow and having a guide slot therein engaging said vertical rod. l

y 5. A snow plow of the V type having two blades connected to each other at the`V apex ot' Vthe plow, bracing ktor the blades including upperand lower erossbars connected to the rear ends of the blades', a vertical rod connected to the central portion ot the .cross bars, andauyielding pushing elenientpivotally connected to the plow between tht-apex thereof and the vertical rod, said pushing element extending to the rear of theplow and having a guide slot therein engaging said vertical rod.

6. `A snow plow of the V type having two blades `connected to each other at the apex of the plow, bracing for the blades-including upper and lower cross'bars connected to l the rear ends of the lblades, a vertical rod connected to the central portion oit the cross barsya' longitudinal connected to the apex of the plow and' the lower Across bar, a horizontal rod mounted for recipiocatfion in two guides connected to the" longitudinal bar, a pusher pivotally connected to the horizontal rod between the guides, a' coinpression spring on thehorizontal rod arranged to be con'ipressed' by the pusher and the load on the'plow, and guiding 'i'neans oil the pusher engaging the vertical rod.

In testimony/'of which intention, l llave hereunto set my hand, at Kennett Square, Pa., on this ninth-day of March, 1926.
