6 Claims.
This invention relates to snow plows, adapted to be Connected to the front of a vehicle for forward propulsion and particularly'to an improved carriage frame and supplemental supporting frame for snow plows.
The primary object of this invention is to provide a light yet durable carriage frame, that'will allow the plow mould board to rise at either end portion independently of the opposite end portion when encountering an obstruction on the road surface. p
In contemplating the above objective, I have provided a carriage frame with pivotally mounted thrust bars which rest independently on spring members to provide a resilient, bi-motional attachment to the supporting frame. It follows, the thrust bars are also pivotally attached to the said supporting frame. Thus, for example, when the left end of the mould board encounters an obstruction on the road bed, it will rise substantially vertically and the left thrust loar will settle on the supporting spring member without altering the position of the right thrust bar and right end of the mould board to any, appreciable extent.
A further object of the invention conditional to the primary object is to provide means whereby the mould board may meet, and be elevated over, an obstruction on the road bed with a minimum amount of shock to the mould hoard, carriage frame and supporting frame.
A still further object of the invention is to provide a carriage frame of extremely simple construction giving due regard to strength and efficiency. I
Still another important object of the invention is to provide a supplemental supporting frame that may be easily attached to the vehicle chassis in a manner whereby the weight of the said supporting frame and carriage frame is supported above the vehicle springs to alleviate stress and strain on the wheels and axlesof the vehicle. I have accomplished thi object by securing the supporting frame to the longitudinal members of the vehicle chassis in a mannerso that certain brace supports are bolted or otherwise secured over the front wheels. v
A still further object is to provide adjustable thrust bar facilities so that the mould board may be yieldably maintained at varying determined positions relative to the road bed.
With these and other objects in view which may appear as the description proceeds the invention resides in the novel construction and arrangement of co-operating parts as hereinafter more specifically set forth, claimed and shown in the accompanying drawings forming part of this application and in which:
Fig. 1 is a plan view of the improved carriage frame, showing its position relative to the vehicle chassis and mould board.
Fig. 2 is a rear end elevation view of the carriage frame.
Fig. 3 is a side elevation view of the device in which the carriage frame and supplemental supporting frame are disclosed. V
Fig. 4 is a perspectiveview'of the supplemental supporting frame.
Referring more in detail to the drawings in which similar reference characters designate corresponding parts throughout the several views, I have shown a vehicle chassis ID to which the supplemental supporting frame is secured. It may be noted here that, although a particular vehicle chassis has been taken for purpose of illustration, the device may be readily secured to any standard vehicle in a similar manner with due consideration being given to structural modification of a minor nature.
The supplemental supporting frame consists of two upright supports II and J2 which are connected to each other by upper and lower lateral and parallel braces l3 and I4 which are welded or otherwise secured to the upright supports. I have provided channels l5 and Hi to receive the thrust bars of the carriage frame which will hereinafter be described in detail. The said channels, depend from and are partially supported-by the lower lateral brace l4. Aligned holes I! are provided in the channels so that the thrust bars may be adjustably secured to the supplemental supporting frame. A lateral brace 18 is secured to the lower extremities of the said channel members [5 and Hi. In the drawings Figure 4, I have shown the combination of angle iron and strap iron for a channel member, but it should be understood that two lengths of angle iron or one length of channel iron of predetermined size would suffice. The present combination is to provide means of adjusting the width of the channels l5 and IS.
The support frame is connected to the chassis ID by means of inclined braces l9 and 20, welded or otherwise secured to the lateral brace l8 and extending rearwardly to the chassis l0 and bolted thereto above thewheels 2| of the vehicle. The said inclined brace members are supplemented by coacting braces 22 and 23 secured to the lateral support l4 at either extremity and extend ing rearwardly to the chassis frame l0 where they are secured in any suitable manner. A strap iron connecting member 24 may be provided to V strengthen and relate the braces whereby the supplementary supporting member is attached to the chassis.
Angle plates, generally designated as 25 are suitably disposed throughout the structure at the various positions where torque is likely to occur to alleviate this strain.
It will be seen, particularly in Fig. 3, that the usual attachments are provided as a necessary part of the equipment but are not claimed as being new and useful in the art such as the headlights 26 and plow hoisting mechanism 21. It
will be readily noticed I have used angle iron" bracing throughout the construction of the supplemental supporting frame, however, it
should be understood that the method of attaching the said supporting framelis the primary. feashoe 32 are adapted to support the mould board a predetermined distance 'above the. ground level and to frelieve the wearand'tear-on the:mould board.;
The-upper portion of the mould boardill is supported substantially centrally-by an adjustable brace rod33-which is composed of telescopic members pivotally attached to'the mould board by.-lugs 34 and to the carriage frame A in the same manner 35.- A plurality of; holes 36 are :providedinthe tubular portion ofthe brace rod 33' whereby the length of the said rod may be varied to. position the mould board at the proper angle with-respect tothe road surface.
The immediately-preceding paragraphs havev des cribed a simplegand efficient mould board and mould board attachmentlm eansthat I have successfullyadapted for the purpose of'the invention, incombination with the carriage frame to be hereinafter described in detail. However, my carriage framesisfsuch that it maybeusedonanyrtype 0f 'mould board attachment with slight modification and in. addition isequally success fullusedinrcombination withthe one-Way type of mould board andthe V-type of. mould board Therefore, it should-be understood that the carriageframe is a distinct unitadaptabletobe successfully used with the majority of snow plow mould boards. v V
In carrying out the objects associatedwiththe carriage frame, I have provided arectangular cal guide bars 42 and the inner vertical guide bars 43 which extend from the rearwardlend of the lower frame-31'. A cross member. 44 is welded;
tothe'saidrguide bars at the upper extremity to rigidly retain. sameinposition. "The carriage frame is attached to the supplemental supportingframe bymeans. of the- thrust bars 38 and 39 which are hingedly connectedto the supporting frame by means of pivot bolts 45 through the channels I5 and i6.
Reverting to the thrust bars 33 and 39 it will be seen particularly in Fig. 2, that they rest upon and are supported in the raised position by spring leaves 46 on which metal spaces 41 are situated to alleviate the wear and tear on the spring leaves. The said spring leaves are bolted at 48 to the lower frame 31 and are maintained in guides at their'extremities between the vertical guide bars 42 and spaced apart guide bars 49 which extend vertically from the base 31.
In summing up the particular advantages of the structure it will be noted that the supple- 7 mental frame may be readily attached to and detached from the chassis by means of bolts through the said chassis and the braces I9, 20, and 22, 23. During the period when a' more or less permanent use of the device is required the supplemental supporting frame is left on the vehicle chassis and the mould board and carriage; f rame quick'ly and easily rrdetached to; the said supporting frame: by simply removing' the pivot vbolts 45 from-the 1 channels I 5 and! 6 and.
