FLOOR-DRESSING MACHINE.

To all whom it may concern:

Be it known that I, EDWIN WV. WVHITMORE, of WVorcester, in the county of l/Vorcester and State of Massachusetts, have invented certain new and useful Improvements in Floor- Dressing Machines; and I do hereby declare that the following is a full, clear, and exact description of the same.

This invention relates to new and useful improvements in dressing machines and has relation more particularly to that class of machine employed for scraping or finishing a floor after being placed.

It is an object of the invention to provide a .novel device of this character that can be readily operated manually.

It is also an' object of the invention to provide a device wherein is employed a scraping or dressing blade, which may be easily applied and adjusted.

It is also an object of the invention to pro vide a novel machine of this character formed of a plurality of sections movable or adjustable, one with relation to the other.

Further, it is an object of the invention to produce a device of the character noted, which will possess advantages in points of simplicity and durability, proving at the same time comparatively inexpensive to manufacture.

With the foregoing and other objects in View, the invention consists in the details of construction and in the arrangement and combination of parts to be hereinafter more fully set forth and claimed.

In describing the invention in detail, reference will be had to the accompanying drawings, forming part of this specification wherein like characters denote corresponding parts in the several views, in which- Figure 1, is a sectional view of the invention. Fig. 2, is a top plan view with one of the parts being shown in an adjusted position, the normal position being indicated by dotted lines. Fig. 3, is a view in perspective of the invention, certain parts being indicated by dotted lines. Fig. 4, is a bottom plan view of one part of the invention. Fig. 5, is a View in elevation of a detail of the invention, and Figs. 6, 7 and 8 are views in perspective of other details of the invention.

In the drawing 1, denotes the forward or truck section of the machine which is mounted by any desired means on the axle 2, having the wheels 3. This section 1, projects Specification of Letters Patent.

Application filed May 22, 1907.

Patented July 7, 1908.

Serial No. 375,189.

rearwardly of the axle 2, and its wheels, and

is provided with a perforation 4, through which passes a bar 5, the head 6, of which being counter-sunk 1n the under surface of the section 1, as is thought to be fully shown '1 in Fig. 1. This bar, when in applied osition, passes through an opening 7, in register with the opening 4, in a forward extension 8, projecting from the rear section 9. These sections 1 and 9, and more particularly 9, are

formed of'cast metal in order that agreat weight may be obtained, the purpose of which being, it is thought, clearly apparent to those skilled in the art.

The upper portion 10, of the bar 5, is threaded and is engaged by the nut 11, which is intended to bind the two sections 9, and 1., together and to permit the section 9, to be moved or adjusted laterally with relation to section 1. In order that this lateral movement may be obtained, the rear edge of the section 1, is provided with converging inclines 12, as is, it is believed, fully shown in Fig. 4, and indicated by the dotted lines in Fig. 2.

The under-face of the section 9, is provided with a recess extending transversely of the machine and the walls 13, thereof are ranged on an incline. Communicating with this recess is an o ening or bore 14, which extends downward y through the section 9, approximately centrally thereof. Positioned within the recess is a clamping plate 15. This plate 15, is provided with perforated lugs 16, Fig. 8, and is pivotally held to the section 9, by screws 17, which pass through the perforations of the lugs 16, and engage said section 9. Between a wall of the recess and the plate 15, is interposed the scrapin blade 18, which is edged or shaped on a beve with the cutting edge set forward. The cutter is set when in applied position with the edge as much off the edge of the plate as is required to contact sufficiently with the floor. The cutter blade and plate are held in operative position by the bevel or wedge block 19, which is engaged by a bar 20, which extends through the wedge 19 and through an. opening 14. The upper portion 21, of the bar 20, is threaded and is engaged by the nut 22. It is thought that it will not be necessary to set forth the steps as how the cutter may be applied or adjusted, as it is believed such 0 eration is obvious from an inspection of the drawings.

chine being operated from an upright While the elements 11, and 22, have been termed nuts, it is to be stated that the term hand wheels is also applicable. The pivotal or adjustable connection between the.

., handle may also be of any length, that is to say, of such a length as to permit the maosition, of less length, as may be requirec by the necessities of practice.

What I claim is: 1. In a floor dressing machine, aframe having a recess, a blade within said recess, a

clamping plate for the blade pivotally carried by the frame, a wedge acting in con unction with the plate to hold the blade in position, a bar engaging the wedge and extending through the frame and means engaging the bar for controlling the wedge.

2. In a floor dressing machine, a frame comprising two sections pivotally secured one to the other, one of said sections being provided with a recess, a blade within said recess, a clamping plate for the blade pivotally carried by the frame, a wed e acting in conjunction with the clamping p ate to hold the blade in position, a bar engaging the frame, and means engaging the bar for controlling the wedge.

33. In a floor dressing machine, a frame having a recess, a blade within the recess, a clamping plate for the blade within the re cess pivotally carried by the frame, a wedge within the recess acting in conjunction with the plate to hold the blade in position, a bar engaging the wedge and extending through the frame, and means for engaging the bar for controlling the wedge.
