PATENT WHEELED SCRAPERi SPECIFICATION forming part of Letters Patent No. 48,595, dated September 29, 1896.

Y Application iiled November 5, 1895. Serial No. 568,007. (No model.)

. a full, clear, and exact description.

Our invention relates to an improvement in wheeled scrapers, and especially to an improvenient in the scraper for which Letters Patent were granted to us November 2l, 1893, No. 509,278.

The object of the invention lis to provide a scraper in which the scoop will be entirely under the control of one man, the manipulator beingalso capable of driving the team attached to the machine, and to so simplify and rearrange the parts of the machine that the entire machine will be under better control of said operator than heretofore, and whereby also the scoop may be much more readily and effectually carried to the dumping position or restored to the working position.

Thel invention consists in the novel construction and combination of the several parts, as will be hereinafter fully set forth, and pointed out in the claims.

Reference is to be had to the accompanying drawings, foriningapart of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

' Figure l is a side elevation of the machine, one of the supporting or traction wheels being removed. Fig. 2 is a plan view of the same. Fig. 3 is a rear elevation thereof. Fig. 4 is a partly sectional rear elevation taken substantially on a vertical plane coin? cident with the axle of the machine. Fig. 5 is a detail view of the right-hand disk, adapted as one of the supports for the scoop and likewise adapted as a locking-disk. Fig. 6 is a plan view of the draft-pole sheath and a portion of the pole of the machine. Fig. 7 is a longitudinal vertical section taken substantially on the line 7 7 of Fig. 6. Fig. 8 is a transverse sectional view through the axle, illustrating the connection with said axle of the rear port-ion of the scoop whereby the same may be readily elevated. Fig. 9 is a detail view of one of the bearings of the shifting shaft; and Fig. l0 is a side elevation of the pole of the machine, illustrating the connection therewith of the draft device.

In carrying out the invention the ground or traction wheels l0 are loosely mounted upon an axle Il, and the inner face of the hub of each ground-wheel is provided with an attached ring or band 12, having clutchteeth upon its inner face. Adjacent to the clutch-face of each traction-wheel a disk A is splined on the aforesaid axle, and each locking-disk comprises a cupped body 14, the body portions being carried over the clutchrings l2 of the wheels, so as to exclude dust therefrom', and also a flange l5, which is located at the peripheral portions of the inner face of the body. This flange is preferably made wider at one side than the other, as illustrated particularly in Fig. 5, and the left-hand disk is adapted particularly as a locking-disk, having a pocket 17 made in the lower portions of the wider section of its iiange, a shoulder 16 being formed at the -upper portion of the said iiange, as is likewise best shown in Fig. 5.

At each side of the longitudinal center of the axle a shifting sleeve 18 is mounted to slide upon the said axle and turn therewith.

Each shifting sleeve is provided at its outer face with a iiange 19,and bolts 20 are attached to the iianges of the said sleeves and are passed outwardly through openings made in the body portions of the disks A, and within the body portion of each disk a clutch-ring2l is loosely mounted, and the said clutch-rings are secured to the bolts 20, as is particularly shown in Fig. 4, the clutch-rings of the shifting sleeves being adapted for engagement with the clutch-surfaces of the Wheels, although they are normally held out of such engagement. Lugs 2la are produced in the body of each disk A, being adapted for engagement with lugs 2l", made upon the peripheries of the clutch-rings 21, in order to relieve the pressure upon the bolts 20, as shown in Fig. 4;.

The frame of the machine may be said -to. comprise the yoke-section B. This yoke-section is .loosely mounted upon the axle, as shown in Fig. 4, the mounting occurring adjacent to the inner faces of the shifting sleeves IOO y 1S, and in addition to the yoke B the frame comprises a horizontal and longitudinal extension B of the yoke, located over the central portion of the machine, being carried in a forwardly direction.

The extension B is hollow and its inner surface is so constructed as to form a slideway 2l, as is best shown in Figs. G and 7, for the reception of a slide 23. In the upper surface of the extension B of the frame a horizontal slot 2l is made, extending from the front to the rear, and the forward portion of the extension of the frame is in a measure closed by a strap or yoke-bar 25, and adjacent to this bar a latch 2G is hinged upon one side of the frame extension, the said latch normally extending over the top of the extension and engaging at its opposite side with a keeper 27, as shown in Figs. 2, (l, and 7, and normally the slide 23, contained within the frame, is prevented from moving at predetermined periods by reason of a stop 28, formed upon the upper forward portion of the slide, engaging with the latch 2t. The latch 26 at its pivot end is provided with an extension 2U", shaped in such manner as to receive the foot of the operator, and the keeper 27 is of angular construction, as shown in Fig. 7, comprising a vertical and a horizontal member, the horizontal member serving to limit the upward movement of the latch, and the said upward movement will be such as to permit of the passage of the stop 28 of the slide beneath the latch and likewise the passage of a keeper. 2S, which is secured to and extends forwardly from a post or upright 29, located upon the rear portion of the slide, as is shown in Figs. 6 and 7.

It will be understood that the slide 23 consists of two parallel bars, as shown in Fig. G. rlhe forward or yoke-bar 25 of the extensionframe is higher than the latch when at its full upper position.

If in practice it is found desirable, frictionrollers may be placed at various points in the slide, so as to facilitate the travel of the latter in the extension of the frame, and this extension may be termed a sheath for the slide. The pole is secured to the forward end of the slide 23 in anyV suitable or approved manner.

The clutches adapted for engagement with the hub-sections of the supporting-wheels are operated through the medium of a shaft 31, encircled and controlled by a spring 3l, which shaft is journaled in bearings 32 and 2523, secured to the under face of the extension of the frame, and one of the bearings is illustrated in detail in Fig. 9, in which it will be seen that the opening 3l through which the shaft is passed is slightly elongated. The rear bracket or bearing 33 is longer than the forward bracket. Therefore the shaft has a rearward and downward inclination, and the aforesaid shaft is rocked either through the medium of a foot-lever 35 (shown best in Fig.

l) or a hand-lever 3G, the hand-lever being at the left-hand side, and these two levers may be continuous, if in practice it is found desirable. Both of these levers, however, as is likewise the latch at the front of the extension-frame, are within convenient reach from the drivers seat 37, the said seat being supported on a suitable standard 38, attached to the rear portion of the frame, usually the rear bow-section B thereof.

The shifting shaft 3l carries at its rear end a disk 39, firmly secured thereto, and two arms and l-l are pivotally connected with the said disk at diametrically opposite poin ts and the arms extend in opposite directions, one to an engagement with each of the shifting sleeves 1S. rlhe opening 34 in the lower hanger or bracket 33 of the shifting shaft permits the shifting arms to be so operated that a single clutch may be brought in to action at a time and be slid into connection with a traction-wheel l0.

A scoop C is supported at its sides by attaching to these faces upwardly-extending arms 42, and these arm s are pivotal] y attached to the disks A at the lower portion of the enlargement of their flanges 15, preferablyj ust below the pocket 17 on the right-hand disk and at a corresponding point on the left-hand disk, so that when the axle is revolved the disks are turned also, and the scoop will be carried upward or downward according to the direction in which the axle is turned. The scoop is locked in an upper or in a lower position by means of a locking-bolt 43, adapted for engagement with the shoulder 16 of the left-hand or locking disk when the scoop is in its lower or working position, as shown in Fig. i, and this bolt will enter the pocket 17 of this disk when the scoop is raised, holding it in such position. This latch, as illustrated in Fig. 2, is preferably provided with abifurcated rear section, and at its bifurcated point is pivoted to a rear upright tl-n of a substantially U bracket 14, secured upon the lefthand portion of the rear frame-section B, the forward member 4:41 of this bracket being adapted as a guide for the bolt, and the bolt is operated through the medium of a lever 45, which is preferably fulerumed in the bifurcated portion thereof and is curved at its lower edge to bear upon the plane or bottom surface of the bracket -i-i.

The scoop is dumped after being raised to an upper position by the action of the slide 23, the said slide being carried forward by the movement of the beam when the latch 2G is opened up. The attachment between the slide and the scoop is shown in Figs. l, 2, and 8, as is likewise the attachment between the axle and the rear of the scoop, the latter attachment being for the purpose of so inclining the scoop as to insure all of the material being emptied therefrom.

rlhe scoop is provided at the rear with an upwardly and rearwardly extending ear 4G,

IIO

and this ear is pivoted in an elongated slot 47, which is made in the rear end of the horizontal member of a substantially T-shaped arm D, and the forward end of the said member is upwardly curved and pivotally connected with a crank-arm 48, secured, preferably, upon the central portion of the axle 11, as shown in Fig. 8. The upper end of the vertical member of the said T-arm D is pivoted between the rear extremities of two links 49, these links being pivoted at their forward ends to the. rear upright 29 on the slide 23. Stirrups 50 are preferably secured to the forward portion of the frame extension to receive. the feet of the driver.

In order to facilitate the draft, an attachment is provided to the pole 30, (shown in Fig. 10,) whereby the draft will be obtained from the rear end portion of the pole, and to that end a link 51 is placed beneath the pole and is pivotally connected to a fixed clevis 52 at the heel of the pole; and the said link 51 is led beyond the forward extremity of the pole through a guide 53, being provided at the said forward end with means for attachment to a whifiietree.

The operation of the machine is substantially as follows: Taking it for granted that the scoop is in an upper position, in which event the locking-bolt 43 will be in the pocket 17 of the lockingdisk A, when it is desired to drop the scoopl to scrape the road this is accomplished by drawing the lever inward,

thereby carrying the bolt 43 out of engagement with the said disk, and the scoop by reason of its weight will drop to the ground after the latch 26 has been raised to release the rear catch 28 of the slide from engagement with it. After the scoop has dropped to the ground and as the horses are driven forward a predetermined distance, the bolt being then in engagement with the shoulder 16 through the medium of the

lever

35 or 36, which may be operated by foot or by hand, the clutches on the axle will be brought into action and engage with the clutch-faces of the friction-wheels, therefore revolving said axle and causing the attached disks A to be carried upward, and they will carry with them the scoop. The scoop will continue to be raised until the locking-bolt 43 will have entered tlie pocket 17 of the left-hand lockingdisk,whereupon the clutches are carried out of engagement with the friction-wheels, it being understoodthat the clutches can be operated either by the hand or the foot lever, the spring 31a upon the shaft 31 releasing them when the pressure is relieved. The scoop being in its upper position, when the dumpingground is reached, thedriver will raise the latch 26, and the horses, drawing forward, will carry the slide with them, thereby tilting the scoop upon its pivotal support and causing the load to dump, the crank connection of the rear supporting-arm of the scoop with the axle being such that when the scoop is tilted it will assume a position of steep inclination. When the slide has been carried forward to the full extent of dumping the scoop, the latch 28a will have passed and become positively engaged with the latch 26, the said latch having been permitted to drop and hold the scoop in its dumping position. In order to carry the scoop downward again to'the ground, the latch 26 is raised and the lockingbolt is disengaged from the left-hand disk by the operation of a hand-lever 45, and the weight of the scoop will carry it to its lower position. This return of the scoop may be aided, if necessary, by a backing of the horses. The object of the crank-and-lever connection between the axle and rear end of the scoop is to provide a pivotal mounting for the arm D, so that it may swing upwardly at its rear end in the manner above described. As thewaxle rocks, the crank-arm will swing and carry the arm D in a corresponding manner clear of the ground under all conditions.
