Application January 21, 1933, Serial No. 652,776
9 Claims.
The objects of this invention are:
First, to provide improved hydraulic control means for the elevation of a snow plow or scraper.
Second, to provide improved detachable attaching m ans whereby different sizes and different designs of. snow plows can be readily installed the one for the other.
Third, to provide improvements in the framework .of such structures.
Fourth, to provide improvements in the hydraulic cylinders and controls.
Further objects and advantages pertaining to details and economies of construction and operation will appear from the description to follow. I accomplish the objects of my invention by the mechanism and means illustrated in the accompanying drawings, in which:
Fig. l is a detail sectional plan view taken on line of Fig. 2.
Fig. 2 is a detail vertical sectional elevation View takenon line 2-2 of Figs. 1, 3, 6, and 7, the forward ends of the brace rods bein shown.
Fig. 3 is a detail front elevation View of the carrying frame and slides and hydraulic means with asnow plow detached and the position of the truck and chassis indicated by dotted lines, the forward ends of the brace rods being shown.
Fig. 4 is an enlarged detail fra mentary view of the plow carrying slides.
.Fig. 5 is an enlarged detail sectional plan View taken on line 5-5 of Figs. 1 and 2.
Fig. 6 is an enlarged detail plan View of the hydraulic cylinder and adjacent parts, taken on line 6-45 of Figs. 2, 3, and '7.
Fig. '7 isa detail sectional elevation View taken on the plane of line 'l'| of Fig. 6, the guide pulleys for the actuating cables being shown in full lines and the ends of the frame being broken away, 4
the actuating pump means being shown diagrammatically and being carried by the truck chassis.
The parts will be identified by their numerals of reference which are the same in all the views.
is the front cross bar of the truck. 2 is the main supporting cross bar of the frame for the hydraulic cylinder. This is connected to the truck chassis by a pair of U-shaped brackets 3 being suitably bolted in place. The frame side bars 5 extend upwardly and inwardly to connect to the hydraulic cylinder bracket 5 to which they are secured by suitable bolts 6. These bars 4 are braced by brackets H and brace rods 42, the forward end only of the brace rods being shown, the rear ends being connected to the frame. Vertical slideway angle bars 1, preferably I-bars, are electrically welded or otherwise secured to the upright portion of the frame bars 4. The guideways are preferably machined to make them true. On these are carried the snow plow 8 which is provided with a main cross web 9. This plow is carried on the slides Ii) which are made up of fiat 5 bars disposed as seen in cross section in Fig. 1 to embrace and reciprocate upon the slideways l.
A forwardly projecting lug H is on each slide, containing a pin hole l2 for the attachment of the snow plow and a pin hole l3 for the connec- 10 tion to the link i l for the hydraulic connection. On the brace web 9 are secured a pair of. lugs l5 whicharedisposed toembrace the lug at each side and through which is disposed the connecting pin it retained in place by washer H and cotter pin [8.
Secured to the lower cross member 9 of the plow are a pair of engaging lugs I9, I9 at each side which hook upon and engage the lower end of .the guide ill when the plow is brought into place. The plow is elevated by the vertical hydraulic cylinder 2|]. carried by the bracket 5 to which it is clamped by the clamping bolt 5|. Within this reciprocates the hollow plunger 2| which is .a section of smooth pipe machined or otherwise with its upper end enclosed at 2|, although the plunger mi ht be a solid cold rolled shaft. To the lower end of the plunger is secured by welding or otherwise the crosshead 22. A regular form of stuffing box 23 is provided at the lower end of the cylinder, full size thereof, as is seen detailed in .Fi 7. The crosshead engages guide ribs .or ways 2 on vertical members 25 of the frame.
The bracket 5 is provided with laterally projecting arms .52 carrying journal pins 53 on which are journaled guide pulleys Ell, 54 at each side.
A cable 26, at its central part, is secured by clamp ,2'l to the central part of the crosshead and is extended laterally over the guide 40 pulleys M and downwardly to the connecting links it at each side.
:Fluid is delivered to the hydraulic cylinder through connection 28, being provided by a regular hand pump mechanism indicated diagram- 4-5 matically at 29 or by a power driven pump mechanism indicated diagrammatically at 36, either being connected as desired or required through the T 3|.
My improved hydraulic cylinder means and connections can be used for the control of any sort of a plow. The attaching means are available either for an A-shaped plow or for a straight blade scraper, as desired. My invention does not relate to the form of the plow, other .55
than to provide it with the suitable guide connections. The plow is very readily attached and detached.
'The truck with the slideway frames thereon is driven up to the back side of the plow'and the parts are shifted until the plow can be raised into position and the engaging lugs l9, l9 engage the lower end of the slide E0. The lug H is then adjusted between the ears l5, l5 and the pivot pin l6 inserted. When this is done, the plow is ready to be manipulated and be moved up and down with facility by the actuation of the hydraulic cylinder. The plow is very firmly engaged and held in place to do its work, being capable of adjustment up and down to meet the requirements.
To detach the plow, it is only necessary to drop it down onto the ground when the lugs l9, l9 will be disengaged and the withdrawal of the pin l6 releases the plow and the truck is ready for another style of plow or any other style of scraper or digger that may be desired.
The plow may be provided with lateral wings. I show a pivot 32 at one side therefor, see Fig.2.
Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:
