This invention relates to a device or apparatus for removing or displacing dirt, sand, snow. and other materials, whether loose solid and it includes in ils functions the 0bjects of that class of apparatus denominated generally as back fillers, bull dozers, scrapers, surfacers, etc., the present device being designed to perform with superior facility the various objects, singly or combined, of each 1 of the designated classes of implements.

Of the manifold objects of this invention, the prime one is to provide a simple, strong, durable and ellicient adjunct-ive unit for a traction device of any desired type by which the pull of the traction device causes the unit to push objects, whether dirt, snow, roadmetal, boulders and the like, ahead or to one side of it.

Another object is to provide an accessory of this general character, in connect-ion with a traction means, 'and connections with such tractionmeans by which the accessory or unit under normal conditions, will remain parallel with the surface operated over or 5 upon while the traction device or power unit is free to respond to surface irregularities without affecting the unit and by which strains on the tractor and strains tending to distort the adj unctive unit are eliminated.

Other objects of the invention are to provide, in combination with a tractor, a unit that is connected therewith for relative pivotal and tiltable movement: to provide a unit with a replaceable head: to provide means by which the pivotal and tilting movement of said unit may be effected, and to pro vide a device of the general character referred to which may be readily cont-rolled and manipulated by a single operator.

The invention relates to and is an improvement over that type and character of machine or apparatus described and claimed in my co-pending application for patent filed 5 March 3, 1923, Serial Number 258,761, new

n a generic sense, the invention consists of a frame arranged to surround a vehicle or traction device of any chosen type and to be connected with the traction device and pr ferabl y to the drawbar thereof, in such manner that it may be tilted to one side or the other; 95 means being provided on the traction device by which such tilting may be accomplished and means also being provided to elevate or lower the front of the frame, which constitutes a separable element replaceable by anl other or other elements as conditions demand or require for the performance of diilerent classes and characters of work.

in av more specific sense and referring in particular detail to the accompanying drawings, my invention is shown as comprising a frame A, consisting of

side members

1 and 2, the rear ends of which are rigidly secured to and conjoined by a substantial cross bar 3, and the front ends of which are arranged to be conjoined by carriers 4 and 5, shown in Figs. 11. 12- and and 13 and 14 respectively. which are detachably connected to said

side members

1 and 2 for the purpose of interchanging them, when the class of work to be done requires such interchange. For this purpose each of the

side members

1 and 2 of the frame A is provided with an extension (3 and 7, which are arranged to engage in

bores

8 and 9 and 10 and 11 respectively provided in the carriers iand 5, the connections between the extensions 6 and 7 and the carriers 5 and 5 being substantially swivelled one. and the union between said carriers and 5 and said extensions being insured and eil'ectcd by mutually engaging locking means 12 and 13 provided on the carriers and the ,s of the

side members

1 and 2 of the in. l crring to Figs. 11 and 12, the cara; there shown is adapted to receive and 'iport blade carrying head 14 Figs. 9 and L. hich provided with a rearwardly extent mg circular bearing 15, that is arranged to lit into a recess or socket 16 in the carrier -.l-. the. bearing 15 being held within said sockb carrier and the bearing 15 and about vnarh pin the hearing may be swung in a limited arc. The bearing 15 is provided with 12C a plurality of holes 18 to receive bolts 19 which are adapted to abut against the edge of the carrier, as shown in Fig. 1 and thereby define and maintain the angle at which the head and its blade 20 have been set.

Referring to Figs. 13 and let the carrier 5 there shown is arranged to receive and support a blade 20 that is adapted principally for straighoahead displacement of earth or objects and for that reason so con- 09 nccted to the carrier that it may be adjusted tically but not horizontally relatively reto.

055 bar 3 which is practically an by a king pin 17 which extends througheaner integral unit with the

side members

1 and 2 of the frame A, connected centrally thereof with the draw bar 21 of the tractor .22, by

a pin 23 which extends through an aperture 24, which, as seen in Fig. 8, is diametrically to larger than said pin, thereby enabling the rear bar 3 and frame A to pivot thereon and to be tilted relatively to said draw bar 21, when for any reason it is desirable to place the cutting, scraping or bull dozing blade at 75 an angle to the horizontal, or relatively to the tractor 22 or the surface operated over.

Each of the

side members

1 and 2 of the frame A is provided on the inside thereof with a wear or

rub plate

25 and 26, which 80 plates are arranged to bear against or contact with complementary plates 27 and 28, rigidly secured to the tractor 22. These plates function primarily to prevent injury to the tractor and also to limit the side moveas meat of the frame A. The plates 27 and 28 form supports for a pair of beams 29 and 30 which are pivotally connected approximatel centrally thereof to said supporting plates 2? and 28. Bearings 31 and 32 are swiveled in or on the ends of said beams 29 and 30 the bearings 31 and 32 being secured or held in connection with said beams by latches 33 and and 34 pivotally mounted on the beams and adapted to engage in grooves 33 and 34' in the bearings 31 and 32. By this arrangement the bearings may be readily cletached or removed therefrom.

In said bearings 31 and 32, is journaled a shaft 35, upon which is secured a plurality of 190

sheaves

36 and 37, and 38. The shaft is rotatable in the bearings 31 and 32 and is also longitudinally movable relatively to the hearing 31 which for this purpose is provided with a collar 39 which fits over the end of the 106 shaft and limits the longitudinal move ment thereof. The object of this arrangement is to enable the bearing 31 to move relatively to and in a direction longitudinally of the shaft during the vertical movement of the 110 lever 29 relatively to the other, such movement also requiring that the bearings 31 and 32 be journaled for oscillation in said beams 29 and 30, as described. 2

Flexible connections preferably in the no form of

chains

40 and 41 are employed to mmnect either of the carriers 4- and 5 ill: the

sheaves

36 and 37, and a flexible connectiim a2 is used to connect the sheave 33 with a fluid actuated piston rod 43. the fluid being 320 supplied to and displaced from a cylinder 44. mounted upon the beam 30 and in which the piston is operable. through preferably ble pipes or tubes 45 and ill.

.The 1' *ar ends of said beams connected to threaded standn lorming parts of upright su; which are oscillatably moun ed in journals 51. that are peruuincnti liar-1i to m upon the tractor Sim-c the journals i-l let-l and the assemblies appurtenant thereto are identical in structure and operation, but one will be specifically described reference being made to the detailed views Figs. 15 and 16 Each of the rear ends of the beams 29 and 30 is provided with an eccentric aperture in which is disposed a concentric flanged collar 53 through which the said threaded standards are extended, the said flanged collars 53 by reason of the structure recited, being movable relatively to and in the aperture 52 in the ends of said beams, but maintainin at all times a fixed relation to the longitudinal plane of the standards, thereby forming a protecting medium for the threads on the standards, 47 and 48 which obviously move in arcuatc paths during the elevation and lowering of said beams, by the means which I shall now describe.

Within

housings

54 and 54, Fig. 15, are rotatably contained bevel gears 55 internally threaded for engagement with the threaded

standards

47 and 48, and mounted or resting upon antifriction bearings 56 with which the flanged collars 53 in the ends of the beams are held in engagement by thegravitational over balance of said beams. Motion is imparted to said bevel gears 55, by bevel pinions 57, keyed to shafts 58 journaled in said

housings

54 and 54 and carrying

hand wheels

59 and 59 by which said shafts and their pinions 54 are rotated to cause the bevel gears 55 to travel up or down upon the threaded standards f? and 48 and thereby raise or lower the beams 29 and 30. Mute-ally engaging means (30 and 61 are provided respectively on the beams and housings to lock said housings against rotation, during the operation of the hand wheels Draft means in the form of chains 62 and 68, Figs. 1 and 2, are used to connect the cross bar 3 with said upright supports 49 and 50, means (if and also being: provided to adjust such draft chains, as conditions require. The draw bar 21, as is usual in certain types of tractors, is under the tension of a spring 66 1,. againstwhich the pull of the frame is rted to a limited extent, it being impracl al for the spring to sustain the force of l on the frame. I addition. a (euispesed spring is incapable of equalizny pull on the cross bar 3, and for this i in, the draft chains 62 and 63 are pro- ,vhich talte up the pull ion; before the .as reached the limit of its compres- Wing thus serving to absorb the it on the initial pull of the trac- 2'9 and 30, one side or the c A and its associated head fted relatively to the trace operated over, through J a -Union of the
