Specification of Lettersfatent.

Patented Aug. 11, 1914.

Application filed February 8, 1912. Serial N 0. 676,438.

To all whom it may concern:

Be it known that I, MARION MARGELLUS Sronnnn, a citizen of the United States, and a resident of Pala, in the county of San Diego, State of California, have invented certain new and useful Improvements in Road-Machines, of which the following is a full and exact description.

One object of said invention is to provide a more simple arrangement of the component parts thereof and bring operating mechanism within easy reach of the operator.

A further important object is to construct a machine that combines the advantages of a road grader, and a scraper, a machine that can move the material to side or center of road and also forward along line of work making fills, turnouts, and removing unevenness in road surface. The change from one class of work to the other, and angle of scraper blade to line of work, can be made by combined action of draft and steering wheels, or by a manually operated mecha nism, without stopping team, or raising scraper blade.

A still further object is to provide a machine, wherein the height of. draft can be regulated to suit the position of scraper blade or class of work.

WVith these ends in view the invention consists in novel combinations of mechanisms, and in the construction and arrangements of devices which will be hereinafter described and claimed.

In the drawings in which like characters of reference denote corresponding parts in all the views Figure 1 is a front elevation of a machine constructed and arranged in accordance with present invention. Fig. 2 is a rear elevation, Fig. 3 is a top plan view of the machine, Fig. 4 is a side view of the machine, Fig. 5 is a side view of construction and mechanisms of scraper frame near and along center medial line, Fig. 6 is a detail of elevating mechanism for front of scraper frame.

The present invention relates more particularly to a class of road machines certain forms whereof are described in Letters Patent of the United States, granted me as follows: No. 915,492, issued March16, 1909, No. 927,887, issued July 13, 1909, No. 975,295, issued Nov. 8, 1910, No. 1,006,139, issued Oct. 17, 1911, to which patents reference is here made that the reader may obtain a fuller understanding of the purpose and scope of the present invention.

The present invention differs from the construction disclosed in patents above referred to, in several particulars, principally in construction of carrying frame, in mountings of supporting wheels, in connecting mechanism of the two front wheels, in the introduction of a clutch in shaft on which is mounted the drum for moving endless chain, and mechanism for revolving same, and in other respects as disclosed in the drawings.

The carrying frame in accompanying drawings is formed of angle iron constructed and arranged as shown.

The side bars 12, 12 are bent horizontally as shownin Fig. 3 and vertically as shown in Fig. 4 and are connected in front by bowed cross tie 13, near central medial line by cross tie 14, near rear end of frame by cross ties 15 and 16, the rear ends to framing members 17, 17. Brace members 19, 19 are structurally connected at front end to bowed cross tie 13, and side bars 12, 12. They are then bent downward and upward as best shown in Fig. 4 and connected in rear to sidebars 12, 12. Brace members 20, 20 are attached to side bars 12, 12 near cross tie 15, extending downward as shown in Fig. 4 to union with side bar 12, 12, thence downward and inward, as shown in Fig. 2 to a connection with guide members 21, 21.

Guide members 21, 21 are rigidly connected at top to cross tie 16 near its center. Framing members 17, 17 and 18, 18 are rigidly connected to guide members 21, 21 as best shown in Fig. 4. Truss brace 22 reinforces bowed cross tie 13 as" shown in Fig. 1. Braces 23, 23 connect cross tie 14 with braces 19, 19. The frame thus formed is supported on wheels 24, 24, 25 which are pivotally mounted in forked mountings 26, 26, 27 revolubly in journal boxes 28, 29 rigidly connected to carrying frame. Wheel 25 supports rear of frame and is revolubly mounted on axle 95, structurally connected to wheel mounting 27, and this in turn is suitably journaled inboXes 29, 29 rigidly connected to carrying frame. Thus pivoted the wheel mounting 27 can be rotated in either direction by handwheel 30 attached thereto, and held in any desired position by segmental rack 31 and pawl 32, as best shown in Fig. 2.

Wheels 24, 24 support the front of machine and are likewise mounted on axles 95, 95 structurally connected to wheel mountings 2G, 26 journa-led in boxes 28, 28 thus pivoted, the wheel mounting can be rotated in either direction. It will be observed in this new wheel mounting for combined supporting and steering wheels, that the two journal boxes, and contact center of wheel with ground are in the same vertical plane, This eliminates any adverse leverage, and makes it possible to reduce diameter of worm gear member of steering mechanism, thus quicker action, revolving wheel mounts and turning or reversing machine. The two front wheels are to move in unison, and for that purpose arms 38, 33 are placed on wheel mountings 26, 26 in parallel relation, and extending outwardly therefrom. The arms thus placed are pivotally connected to rod 34, as best shown in Fig. 3. On one of the wheel mountings 26, 26 is placed a worm gear 35, in engagement with worm 36, on

shaft 37 and operated by hand wheel 38, as

best shown in Fig. 3.

The draft device is connected directly to scraper frame, with scraper blade attached thereto. On different work and under vary ing conditions there are changes in position of scraper. Sometimes, as in ditch work, one end of scraper is depressed much below the other., The opposite, when slicing in a bank above road level. It is obvious that some means is necessary in order to adjust the height of draft to the neutral point, either above or below, as may be most advantageous. This is accomplished by a ball. and socket oint mounted on, and moved by, twin screws located at front of machine. The scraper frame is composed of bowed members 47 and 48 shaped horizontally, as shown in Fig. 3. The ends of 47 are formed in bill hook brackets 49, 49 to which the scraper blade 50 is rigidly attached, as best shown in Fig. 4'.

Near rear end of frame are cross ties 51 and 52 rigidly connected with 47 and 48, as shown in Fig. 2. Near the longitudinal medial line are bars 53 and 54, connecting cross tie 51 to frontscraper frame, and to bowed member 47. These in turn are connected by short cross ties 55, 56, 57, 57. Between bowed members 47, 48 are pivotally mounted sheave wheels 59 and 60. In front and along longitudinal medial line is shaft 61 rigidly connected in front to bowed members 47 48, and in rear to cross tie 55, rigidly .mounted thereon, or forming an integral part thereof, is ball 62. Mounted on screws 39, 39 and in threaded engagement therewith, is block 63, within which is formed a socket to fit ball 62, as best shown in Figs. 5 and 6. When assembled the ball 62, within the socket of movable block 63, a ball and socket connection is made between carrying frame and scraper frame. As

best seen in Figs. 1, 3 and 4, screws 39, 39 are to be rotated in order to adjust the scraperframe, by means of a shaft 45 having a rear hand wheel 46 and a forward bevel gear 44 which meshes with the upper bevel gear 43 of a vertical stud shaft 42 at the front of the machine, this shaft 42 carrying an internallytoothed gear 41 which engages gears 40 at the upper ends of said screws 39. Encircling scraper frame, and guided by sheave wheels 58, 59, G0 is endless chain 64, operated by drum (35, mounted on shaft 66, revolved by worm gea r (37, mounted thereon, in engagement with worm G8, on shaft 69, through universal joint 70, to shaft 71, operated by handwheel 72. For purpose of description worm gear 67, and intermediate mechanisms to handwhecl 72, is termed, locking and manually operating device for flexible draft member. Shaft (36 is in two sections, the rear section carrying drum 65, and forward section carrying worm gear 67. On front end of rear section is placed the fixed member 7 8 of a clutch, and on rear end of front section, is placed the movable member thereof 74, working over the feather key 75. Between clutch member 74, and collar 76 rigidly attached to shaft (36, is placed a compression spring 77.

On clutch member 74, and encircling same, is formed a groove to engage forked end of lever 78, pivoted at 79. The opposite end of lever 78, is likewise forked, to engage similar groove on sleeve 80. Sleeve 80 is movable along shaft 71, and structurally connected to handwheel 72, which is held by feather key 81, locked by pin 82, held in engagement by spring 83, and operated by lever 84, best shown in Fig. 5. To throw clutch out of engagement the operator pulls handwheel. 72, in direction of outer end of shaft 71, till locking pin 82, reaches end of feather key 81, and is forced home at end of said key, by spring 83. This moves connecting sleeve 80, lever 7 8, and movable half of clutch 74, out of engagement with 7 3. To throw in engagement lift locking pin 82, by lever 84. Thus unlocked spring 77 presses 74 in engagement with 7 The object of this clutch is to release the drum and encircling endless belt, from locking and manual operating device, allowing said endless belt to rotate freely and also to lock same in desired position. hen clutch is unlocked the hitching attachment can be moved from one side of scraper frame to the other, or intermediate point by draft of team with auxiliary action of steering wheels. It is locked at desired point by throwing the two clutch members in engagement. \Vith scraper blade at any angle with line of work, and subject to any load or pressure, it can be quickly changed to any other angle by the draft, and action of steering wheels, without Unloading or stopping team. A still further advantage is when machine reaches end of the workings, and is to return, the clutch is released, team is turned, moving draft attachment to opposite side of scraper frame, the supporting wheels are cut to proper angles, the machine is thus reversed, and can resume operation on return trip, Without raising the scraper frame. I believe the foregoing results are not attained by any similar machine, and this, combined with its time and labor saving qualities, make it an important feature of my invention.

For operating rear of scraper frame are chains 85, 85 wound on drum 86, 86 revolubly mounted in boxes 88, 88. On shafts 87, 87 are worm gears 89, 89 in engagement with Worm gears 90, 90 mounted on shafts 91, 91 with handwheels 92, 92. Sheave Wheels 59 and 60 are mounted in movable boxes pro vided with take-up screws 93, 98. Mounted loosely on shaft 66, is friction roller 94: located between guides 21, 21 whose oflice is to hold rear of scraper frame in alinement with carrying frame. Hitching attachment A is formed on endless chain 64.

It is understood without further illustrating that a platform is placed on rear of machine for benefit of the operator and another platform in front under drivers seat.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:

1. A road machine comprising a wheel mounted carrying frame, a flexible draft member having connection with the frame, said draft member having a hitching attachment, a shaft carrying a drum about which the flexible member is extended, a second shaft mounted adjacent said drum shaft, clutch members connecting said shafts, a controlling shaft, worm gears connecting the said controlling shaft and the said second shaft, and means for controlling the engagement and disengagement of the said clutch members.
