A further object is to provide a road finishing machine, having a V-shaped snow plow attachment detachably secured to the forward end of the scarifier draw bars, and operable simultaneously therewith, and, further having a comparatively long scraper blade arranged at an angle back of the snow plow andadapted to receivethe delivery of snow from the snow plow and deliver it to one side of the machine.
A further object is to provide a snow plow attachment for road maintenance machines having means for detachably securing it to the forward end of such a machine and operable by the usual mechanism provided. thereon and said attachment being provided with means for yieldably and forciby holding the snow plow in contact with the road surface. a
The particular object of the invention, therefore, is to provide an improved snow plow attachment, particularly adapted for 1927- Serial No. 195,434.
use in connection with road finishing machines, of ordinary construction, and of the typehaving a scarifier at the forward end thereof.
Other objects of the invention will appear from the following description and accompanylng drawings and will be pointed out in the annexed claims.
In the accompanying drawings there has been disclosed a structure designed to carry out the various objects of the invention, but it is to be understood that the invention is not confined to the exact features shown as various changes may be made within the scope of the claims which follow.
In the accompanying drawings forming part of this specification; Figure 1 is a view in side elevation, showmg a conventional type of road finishing machmewith the improved attachment secured to the forward end thereof;
Figure 2 is an enlarged detailed view showing the manner of securing the attach ment to the scarifier draw bars and further showing the plow in an elevated position;
Figure 3 is a diagrammatic plan view indlcating by arrows the delivery of snow from the V-shaped snow plow to the scraper blade arranged beneath the main frame;
Figure 4 is an enlarged detailed vertical sectional view of the attachment showing the general construction thereof, and also the means for yieldably and forcibly holding ghe plow in contact with the ground surace;
Figure 5 is a detailed sectional view on the line 5--5 of Figure 4; and
Figure 6 is a detailed sectional view on the line 66 of Figure 4, showing the means for supporting the rear end of the snow plow when raised to a non-operative position.
In the selected embodiment of the invention here shown, for purposes of disclosure, there is illustrated a road maintenance machine, of ordinary construction, comprising a main frame 2, mounted upon suitable wheels 3 and 4. The machine here shown, is of the power driven type, and is operable by means of an engine 5, mounted adjacent the rear end thereof as shown in Figure 1.
The usual scraper blade supporting frame or circle 6 is shown connected to the draft bars 7, pivotally connected to the forward end of the machine in the usual manner. The circular frame 6 is operable by means of crank shafts 8, having rods 9 connecting them with the frame as shown.
Scarifier draw bars 11 are also pivotally connected to the forward end of the frame by means of a pivot 12 shown in Figures 1 and 2. A block or holder 13 is secured to the rear end port-ion of the draw bars 11, having means for detachably receiving the usual scarifier teeth 14, shown in dotted lines in Figure 1.. The draw bars 11 are vertically movable by means of connecting rods 15, each having one end connected therewith and having their upper ends pivotally connected to crank arms 16, secured to a cross shaft 17, having a geared connection with a shaft 18 by means of pinions 19 and gear segments 21, secured respectively to the shafts 18 and 17. The shaft 18 is operable by means of a worm and gear drive 22, through an operating rod or shaft 23 having a hand wheel 24 provided at the rear end thereof for the convenience of the operator in operating the worm and gear drive 22 to raise and lower the draw bars 11.
An important feature of this invention resides in the provision of a snow plow attachment adapted to be detachably secured.
to the forward end of the road maintenance machine whereby the latter may be used in the winter time for clearing roads and high ways of snow, thus adapating the machine for all year use. This attachment comprises a V-shaped snow plow having mold boards 25 suitably connected together at their forward edges or ends and having their rear end portions spaced apart by means of a cross frame 26, shown in Figures 3 and 4. A. forked bracket 27 is secured to the forward end of the attachment and is adapted to receive a bracket 28, ivotally connected thereto by means of a pm 29. This bracket is secured to the forward end of a thrust frame 31 having its rear end portions pivotally connected to depending plates 32 and 33, secured to the forward ends of the bars 11, as shown, particularly in Figures 4 and 5. Theplates 32 and 33 are fixedly secured to the bars 11 by such means as bolts 34.
A V-shaped extension 35 is rigidly secured to the forward end of the bars 11 by means of bolts 36 securing it to the upwardly extending portions 37 of the plates 33. '(See Figure 5.) A rod 38 is pivotally connected to the forward end of the extension 35 and has its lower end portion slidably received in an aperture 39 provided in the bracket 28. A stop collar 41 is secured to the lower end of the rod 38 and a similar collar 42 is secured to the upper portion thereof, between which and the bracket 28 a coiled spring 43 is mounted, which constantly tends to urge the thrust frame 31 and therefore the snow plow downwardly into engagement with the ground surface.
