- and exact description.
The invention relates to snow-plows and designs more particularly to provide an improved plow or plowing attachment which may be mounted upon a motor-vehicle to remove the snow from an uneven street.
One object of the invention is to provide an improved plow which is particularly adapted to be operated over a pavement or road and in which provision is made for causing the plow to ride over obstructions and to adapt itself to uneven road-surfaces.
Another. object ofthe invention is to provide an improved plow which may be attached to a motor-truck of usual construction so that the plow may be employed as an attachment to the truck and so that the truck may beused to operate the plow to remove snow from the road. Lastly the invention designs to provide a snow-plow of improved construction.
Theinvention consists in the novel features hereinafter set forth and more particularly defined by claims at the conclusion hereof. lnthe drawings: Figure 1 is a side elevation of a motor driven truck embodying the invention. Fig. 2 is a side elevation of a portion of the plow, showing in dotted lines, different positions which one of the plowshares may be caused to assume. Fig. 3 is a horizontal section through the plowshare, the springconnections for the adjustable sliare'being shown in elevation. Fig. 1 is a vertical section on line 4-4 of Fig.1. Fig. 5 is a section; on an enlarged scale taken on line 5-5 of Fig. 4. Fig. 6 is a detail section showing the device for securing the rear-ends of the side rails of the plowrsupporting frame to the side-rails of the truck-frame- Fig. 7 is a detail perspective showing the manner in which the plow frame is secured to the front of the-motor truck frame.
The improved snow-plowing mechanism is adapted-to be attached to a motor-vehicle f s al estr e on n ment ar ying wheels at, traction-wheels h, a frame a,
a seat d and a'radiator e, as Well understood in the art.
The plowing attachment comprises a fixed share 12 which is inclined relatively to the lines of travel, and has its lower edge disposed a suiiicient distance above the ground, so that it will clear any obstructions on the road, The upper and lower edges of share 12 are curved and the inclination of' the share is such as to deflect the snow in its path, to one side of the vehicle. A supplemental and movable share 13 is adjustably sustained so that it will adapt itself to uneven portions of a roadway, is also inclined ,to the line of travel of the vehicle and has 4 its lower edge disposed to Work below share 12, and in close contact with the ground, so that this share willfollow the fixed share and throw the snow nearest to the ground or that over which share 12- passes, to one side of the vehicle. Both shares 12 and 13 are sustained by a supporting-frame which is adapted to be attached to and removed from the vehicle-frame 0 and comprises side-bars 14: which have their front ends bent downwardly and rigidly secured to brackets 15 on the back of share. 12. The rear ends of side-bars 1st of this detachable frame are Secured in blocks 16 respectively, which are adapted to rest against the sides of the frame (2. Each block 16 has secured thereto, by the bolts 17, a. clip 18 which is adapted to fit against the under side of one of the side rails of frame 0, and has a groove 19 which is adapted to receive the base flange on said rail. A lug 20 secured to block 16 by bolts 21 is extended laterally to overlie andfit against the top of said rail and has a groove 22 in which the top-flange of said rail will fit. Bolts 60 and a. hook-plate adapted 'to engage the front rail of the truck-frame, serve to detach-ably secure the central portion of cross-bar'23 to the truckframe. These attaching-devices serve to rigidly secure the rear end of rails 14 of the plow-supporting frame to the side-rails of the truck-frame a, without the necessityof weakening or drilling said rails. By removing the clips 1-8and lugs 20 the rear ends of side-bars 14 may be disconnected from the truck. i The. plow-supporting frame also comprises a cross-bar 23 which is adapted to lilfi 5 33 will 'be vertically slidable therebetween.
extend over the front end of the truck-frame in front of the radiator c, and has downwaidly extending members or uprights 24 plow-supporting frame is secured to the- .front end of the truckframe, by blocks 27 integrally formed therewith. These uprights are rigidly secured to side-bars 14 by plates and 26. The front end of the which fit incorners between theuprights 24 and cross-bar 23 and are adapted to it against the outer sides of the truck frame, and plates 28 which are bolted to said blocks are adapted toengage the underside of the truck frame. By disconnecting the rear ends of'side-bars 14 from the truck frame and releasing or removing plates 28 the plow sup orting frame may be detached from the 3 cured to uprights"24 and serve to confine truck-frame. v
Braces 29 extend between, and aresecured to, the lower portionf'ofsuprights 24' and side-bars14xand secure the lower ends ofv the uprights against backward stresses.
The adjustableplow-share 13 is pivotally sustained by aro'd 30 which extends through lugs 31 secured to the back of said share and forwardly extendingarms'32 on uprights 33, which are slidably mounted in ways formedbetween uprights 24, and plates 26 and 25 and side-bars 14. Plates 34 are sethe lower portion bfup'rights 33 against outwardmovement and the front ends of braces "29 are extended along the inner faces of these uprights respectively, so that uprights At each side, plow share 13 is yieldingly held in operative position by a device for I pressing it into such position, and which permits the lower portion of said share to swing or tiltbackwardly when an insurmountable obstruction is met with Each of these devices consists of a rod'36 which has its front end pivoted in lugs 37 secured to the back of share 13 near the lower edge thereof, a spring 38 coiled around said rod and engaging a nut 39 which is screwthreaded thereon, a bracket 40 secured toa the lower end of upright 25 and through limiting the action'upon the share by the which rod 36 is loosely extended, and nuts 41 which are screw-threaded to the rear ends of the rod and serve as adjustable stops for spring. By adjusting nuts 39, the tension of the springs may be varied. Consequently, when an obstruction is encountered, the
'- plow-share will be tilted backwardly by the obstruction as indicated by the dotted lines in Fig. 2. Each side of the share 13 is vertically movable independently of'the other,
so that in driving over an uneven roadway or when share 13 has beeii tilted backwardly against the force of springs 38- and the obstruction tends to raise the share, either or both sides of the share may be raised by the obstruction. For this purpose a springlever to tilt.
pressed device is applied to'each upright 33.- Each of these devices consists of a rod secured to the inturned end of the upright.
and extending through one end of alever 43, nuts 44 on'the upper end of said rod, a coiled spring45-between the lever and the upper end of upright 33 and another coiled spring 46 between the lever, and the nuts 44. Lever 43 is centrally pivoted as at 47 to a collar 48 which is screw-threaded to a vertical rod 49 having a hand-wheel at its upper end whereby the rod may be turned to raise and lower the collar. The lower end of this rod is swiveled in a suitable bearing 51 which is'formed of sections and permits the head 52 on the lower end of the rod to be rotated, but holds the rod against vertical movement. This construction permits either of the uprights 33 to slide upwardly in response to unevenness of, or obstruction on, the road.
The pressure of the share 13 on the road may be regulated by adjustment of collar-48 which will, through the spring-connections with the uprights respectively, raise and lower them to correspondingly adjust share 13. When one side of the share 13 is raised by a small obstruction on the rod, the upright 33 on that side will raise against the force of spring 45 applied thereto and tilt or tend to tilt lever 43 against the spring 45 at the opposite side, which will permit the As soon as the plow has traveled over any unevenness the share 13' will be c'aused to assume its former relation in contactwith the ground. When an obstruction is encountered, which would otherwise arrest the machine,'share 13 will swing backwardly against the forceof springs 38. and the share will be curved rearwardly and downwardly to such an extent that it will be deflected upwardly by the obstruction against the force of springs 45. In this manner obstructions will not wreck the plowing-mechanisrnand the share 13 may be used to closely scrape the ground without danger of breakage and without requiring frequent'manipulation upon the art of-the operator. It will be understoo that the pivotal points of the pivotal connection are construction. It also provides a share which may be operated to scrape the-ground and which will yield responsively to obstructions and inequalities of the ground, without danger of breaks. v
The invention is not to be understood as restricted to' the details set forth, as these may be modified within the scope of the appended claims without departing from the spirit and scope of the invention.
