A'ITIJ R N EYS Patented Oct. 21, 1952 UNITED STATES PATENT OFFICE ADJUSTABLE SCRAPER BLADE MOUNTING Harley Rust, Mount Morrison, 0010. Application April 1, 1949, Serial No. 84,826

3 Claims.

This invention relates to scraper blades of the bulldozer type such as used in leveling or pushing snow, dirt and the like, and in particular a blade mounting for removably attaching a blade to the front of a Jeep or the like wherein the elevation of the blade is readily adjustable and in which the blade is hinged and resiliently held to provide tilting movement when the lower edge of the blade engages a fixed obstruction.

The purpose of this invention is to provide means for removably attaching a scraper blade to the front of a Jeep in which the pitch of the blade is laterally adjustable and also in which the blade is vertically adjustable.

In the usual type of temporary attachments for mounting scraper blades on tractors, Jeeps and the like the blade is bolted in a fixed position to provide rigidity and this does not provide sufiicient flexibility for use in scraping snow and the like. With this thought in mind this invention contemplates a mounting for scraper blades wherein the blade is adapted to tilt forward as the lower edge strikes an obstruction and wherein the blade is pivotally mounted for both vertical and horizontal adjustment.

The object of this invention is, therefore, to

provide a scraper blade mounting that may be suspended from a bumper or cross beam at the forward end of a Jeep or tractor and braced from the chassis in which the blade is supported from both sides of the chassis and may be adjusted vertically, and also in which the pitch or angle of the blade in relation to the longitudinal center line of the chassis is adjustable. --Another object of the invention is to provide a scraper blade mounting for Jeeps, tractors, and the like in which the lower part of the blade is hinged to a supporting strut and the upper part resiliently held against the strut so that as the lower edge strikes an obstruction the upper part may swing outwardly to prevent damaging the lower part of the scraper.

Another object of the invention is to provide a scraper blade mounting for Jeeps and the like in which the elevation of the scraper may be adjusted by cables from the operators seat of the Jeep or tractor.

A further object of the invention is to provide an improved mounting for temporarily attaching a scraper blade to a Jeep, tractor, or the like in which the blade is universally adjustable, and in which the mounting is of a comparatively simple and economical construction.

With these and other objects in view the invention embodies ahorizontally disposed channel providing a blade holding strut with a blade hinged to the lower edge of the channel and resiliently held against the upper edge with the channel carried by extensible arms pivotally mounted on the lower ends of vertically disposed posts wherein the posts are carried by a bumper or cross beam of a Jeep or tractor with the lower ends supported by struts from the chassis and with adjusting means for raising and lowering the blade carried by the upper ends of the posts.

Other features and advantages of the invention will appear from the following description taken in connection with the drawings wherein:

Figure 1 is a side elevational view showing the forward end of a Jeep with the improved scraper blade mounting attached thereto.

Figure 2 is a plan view of the scraper blade mounting with the Jeep omitted.

Figure 3 is a cross section through the scraper blade mounting taken on line 3-3 of Figure 1 showing a rear elevation of the blade with the extensible supporting arm shown in section.

Figure 4 is a similar cross section taken on line 44 of Figure 1 looking in the opposite direction illustrating the construction of the attachment.

Figure 5 is'a longitudinal section through the scraper blade mounting taken on line 5--5 of Figure 2.

Figure 6 is a detail showing a bracket for supporting the rear end of the strut from the chassis and spring hanger of the vehicle taken on line 6-6 of Figure 1.

Figure 7 is a detail showing the upper end of the bracket that straddles the side beam of the chassis with the lower part of the bracket broken away.

Referring now to the drawings like reference characters denote corresponding parts, I the scraper blade mounting of this invention includes a channel Ii] on which a blade II is carried, vertically positioned posts l2 and I3 mounted on a bumper l4 and to the lower ends of which the channel H) is connected by extensible arms having bars l5 and i6 pivotally connected to the channel ID by pins I! and I8, respectively, and sections l9 and 28 which are pivotally mounted on a bolt 2| at the lower ends of the posts, and the lower ends of the posts are supported by struts 22 and 23; V

The blade II is pivotally connected to the lower flange 24 of the channel In by hinges 25 and the upper part of the blade is resiliently held against the upper flange 26 of the channel by springs 27 and 28 on bolts 29 and 39, respectively, which are positioned with the heads 3| and 32 thereof extended through the blade and be adjusted by extending one arm more than the other.

The eye beams forming the posts I2 and l 3 are attached to the bumper M by the clamps 39 and- 40 which are held by a bolt 4| and the lower ends of the posts are supported by the struts 22"and 23 which are attached to plates 42 and 43. carried by the lower ends of the posts, respectively. The plates 412V and 43 also. support the bolt 2| on which the rear sections I9 and 20 of the extensible armsarepivotally mounted. The opposite ends of the struts-Hand 23 are freely connected by brackets 44 and 45, respectively, to. the side beams 450i the-Jeep with the brackets positioned. against the spring hangers 4! as illustrated. in Figures 1 and 6. ,As shown in Figuresfi and 7 the bracket 45- isprovided with a flange 48 having a recess 49 therein toreceive the loweredge of the beam and a lower end ofthe bracket is. secured by welding, or other suitable means to the strut 23.

An angle Bil-is supported from the posts [2' and I3 by angularly disposed braces 51 and- 52 on the lower side and 53; and-.54 onthe upper side-Which extend upwardly-to. a cross beam 55: which connects the upper ends of the posts. I22 and I3. A gin pole. 5,6, havinga hub 57 at the lower end is pivotally mounted on the angle 50 by a pin 58 in. ears. 592 and 60; and the upper part of the gin pole is. connected by chains BI." and 62 to the upper flange 26 of the channel 10,, the. upper ends ofthechainsbeing connected to aneye: 6.3. The upper. part of. the gin poleisprovidednvitha cross pin 54 that is positioned to be .engagedby teeth .65. and '65. of latch bars. 6] I andtfiflhwhich arepivotally mounted ona bracket. Bflzthrough a pin 10 in an extension ll of the bracket; The latch bars may be elevated to release the pin 64 by a shoe 12 on alever 13 which is pivotally mounted on thebracket 69 by a pin. 14 andadapted to be actuated by a cable l5. A cable 'l-B may also be attached totheupperend of the gin'. pole 56' wherebythe gin pole may be drawn rearwardly to'elevate the scraper-blade H through the supporting channel l0.

With the scraper blade mountedin this'manner the elevation of theblade-may readily beadjusted and as the lower edgeof the blade strikes a fixed obstruction it may move rearwardly against the springs 28 withtheupper part tilting forwardly. The pitch orangularposition of the blade may also be adjusted through the extensible arms-by which the blade issupportedfrom the'posts l2 and i3.

The scraper blade mounting may readilybe attached to' orremoved from a Jeep through the bolt H'by'whichtheclamps 39 and AO may beadjusted to holding postion orremoved.

It will be understood that modifications may be made in the parts without departing from the spirit of the invention.
