LEVELING AND RAISING DEVICE.

Specification of Letters Patent.

Patented Oct. 31, 1905.

Application filed May 4:, 1905. Serial No. 258,862.

To aZZ whom. it may concern.-

Be it known that I, GARRET H. TENPAS, a citizen of the United States, and a resident of Sherman, in the county of Chautauqua and State of New York, have invented a new and Improved Leveling and Raising Device, of which the following is a full, clear, and exact description.

The object of the invention is to provide a new and improved leveling and raising device which forms a permanent part of a portable machine, such as a grain-separator or the like, and which is arranged to permit convenient leveling of the body of the machine or raising the same, if necessary.

The invention consists of novel features and parts and combinations of the same, which will be more fully described hereinafter and pointed out in the claims.

A practical embodiment of the invention is represented in the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure 1 is a side elevation of the improvement as applied to the rear axle of a grainseparator, parts being broken out. Fig. 2 is an enlarged sectional side elevation of the improvement on the line 2 2 of Fig. 3. Fig. 3 is a cross-section of the same, parts being shown in elevation; and Fig. 4 is a plan view of the same.

The improved leveling and raising device is interposed between the rear axleA and the body or bed B of a grain-separator or other machine, and, as shown in the drawings, the sills B of the bed B are secured to a bolster B preferably formed of two spaced beams provided at their upper ends with guideways B for wedges C and U to' slide in in a transverse direction, as will be readily understood by reference to Figsr2, 3, and 4. The wedges C and O are located near the ends of the bolster B and the said wedges screw on screwrods D and D, mounted to turn in suitable bearings E and E, secured to the frame part of the bolster B The outer ends of the screw-rods D and D are provided with suitable handles or crank-arms F and F, adapted to be taken hold of by the operator for turning the screw-rods with a view to move the wedges C and C independent of each other in a transverse direction either inward or outward on the guideways B The under inclined surfaces of the wedges Q and C are provided with longitudinally-extending guideways C engaged by blocks Gr, each hung on a pivot H, journaled in a suitable bearing I, attached to the top of the axle A, as plainly illustrated in the drawings. It is evident that when the wedge C or C is moved in a transverse direction along the guideway B then the wedge in traveling over the block G is caused to move in an upward direction, and as the top of the wedge C bears against the under side of the sill B it is evident that the bed B is raised on its corresponding side, and if both wedges C and C are caused to travel simultaneously in an inward direction then the entire bed B is raised.

As shown in Figs. 3 and 4, the upper surfaces of the wedges C and C also bear against friction-rollers Jand J, journaled on the bolster B so as to reduce the friction on sliding the wedges C or C inward or outward on turning the screw-rods D or D.

From the foregoing it will be seen that the operator by moving either of the wedges C or G can cause a raising of the corresponding side of the bed B, so as to bring the same to a level in case the aXleAis not in a level position. 1f the bed B is too low, it may be raised to the desired height by the operator moving both wedges C and C in an inward direction. By having the blocks (Jr pivoted it is evident that when one side of the bed B is raised only then the other side practically swings on the corresponding pivot at this side, thus preventing binding of the blocks G in their bearings G of the corresponding wedges C and O.

In order to relieve the pivot H of undue pressure, the ends thereof are provided with rollers H, (see Fig. 3,) traveling on the top of the axle A. In order to guide the bolster B in its up-and-down movement relative to the axle A, the side arms of the bolster are provided at their inner faces with verticallydisposed guideways B*, into which project the ends of a pin A, secured to or forming part of the axle A.

The leveling and raising device shown and described is very simple and durable in construction and forms a permanent part of the vehicle or machine, so that it can be readily actuated at any time with a view to either level the body B or to raise the same, as the case may be.

Having thus described my invention, I claim as new and desire to secu re by Letters Patent- 1. A leveling and raising device for portable machines comprising wedges mounted to slide on the bed of the machine, means for imparting transverse movement to the said wedges, and blocks movably mounted on the axle of the machine and over which slide the said wedges.

2. A leveling and raising device for portable machines comprising wedges mounted to slide transversely on the bed of the machine, blocks pivotally supported from the axle of the machine and over which slide the said wedges, and manually-controlled means for imparting a transverse sliding motion to the said wedges to shift the same independent one of the other.

3. A leveling and raising device for portable machines and interposed between the axle and the bed of the machine comprising trans- GARRET H. TENPAS.
