HERMAN T. HEUSERMANN, OF PEORIA, ILLINOIS.
FLOOR-DRESSING MACHINE.
To all whom it may concern:
Be it known that I, HERMAN T. HEUsER- MANN, citizen of the United States, residing at Peoria, in the county of Peoria and State of Illinois, have invented certain new and useful Improvements in F loor- Dressing Machines; and I do hereby declare that the following is a full, clear, and exact descrip tion of the invention, which will enable others skilled in the art to which it appertains to make and use the same.
This invention pertains to a machine for dressing floors relating more particularly, however, to a device for sandpapering floors.
The object of the invention is to produce a machine of this character that is simple in construction, low in cost, and one that is readily portable as well as one that can be operated by hand as well as by power.
In the accompanying drawing :Figure 1 is a side elevation of my machine. Fig. l is a plan of the under side of a dresser-head. Fig. 2 is a rear elevation of the machine. Fig. 3 is a plan of a pressure lever, and Fig. 4: is a detail of a two-part driving-shaft part of which is shown in section.
The machine consists of a horizontal bed or platform composed of timbers A mounted at their ends upon transverse bars B provided with suitable casters C. Mounted upon the timbers A near their forward ends is an upright frame consisting of vertical timbers D D suitably connected and braced by cross members E secured thereto. Secured to said members D and to the horizontal timbers A are braces F there being but one of them shown, however, see Fig. 1.
G is a vertical shaft carried in bearings H secured to the members E, the upper end of which carries a pinion-gear J with which meshes a similar gear K mounted upon a horizontal shaft L carried in bearings M secured to the members E, said shaft L being provided with a suitable driving member as, for instance, a crank N. Carried at the lower end of the shaft is a sleeve 0 constituting a part-shaft from the lower end of which is suspended a dresser-head beneath the platform consisting preferably of a circular body P whose under surface is provided with a plurality of segmental grooves Q, whose side walls are undercut and radiate from the aXis of revolution of said body.
R indicates slides to enter the grooves the Specification of Letters Patent.

same being removable as indicated in Fig. 1
The sandpaper or other material used for dressing the floor is indicated in Fig. 1 by S the edges of which are let into the grooves Q described and held by means of said slides R which are secured in place as, for instance, by means of buttons T. The sleeve O is detachably carried by the shaft G by means of a pin U which extends through said shaft and through vertical slots V at diametrically opposite sides of the sleeve as shown in Fig. 4 and this structure provides for a vertical movement of the sleeve and its dresser head P.
Mounted above the platform of the machine is a horizontally disposed bar IV supported upon springs 2 held in place by bolts 3. Surrounding the sleeve at each side of this bar is a collar 4 and above the upper collar and beneath the lower one are pins 5 which extend through the sleeve. The said sleeve and its dresser-head are supported by means of this bar and its springs through the upper pin so as to be normally held above and clear of the floor. Connected to the bar is a rod 7 whose upper end is pivoted to a lever 8, one end of this lever being pivoted between a pair of uprights 9 mounted upon the timbers A. The free end of said lever extends rearward between the uprights D beneath a hand-piece 10 secured to said uprights.
In operation the turning of the crank N transmits motion to the dresser-head. Since said head is held normally free of the floorsurface through the springs 2 it is necessary to cause it to lower to its working position and in order to do this the lever 8 is depressed. The left hand of the operator grasps the hand-piece 10 which serves to steady his hand and by bearing with the wrist or fore-arm upon the lever 8 the pressure of the springs can be overcome and the bar W depressed. Without the part 10 or its equivalent the operator could not as readily control the lever. Its use admits of imparting a more delicate adjustment to the lever than would be possible without it. The motion of the body while handling the machine would not admit of holding the hand steady enough to properly control the lever so that a hand rest is desirable. The weight of the dresser-head causes that member to lower this resulting by reason of the slots V;
the pin U of the shaft G interfering in no way with said lowering movement. The upper pin 5 before described which suspends the dresserhead through the bar W, has no office at this time but when forced downward the bar meets the lower pin 5 and through pressure upon the rod '7 will force the dresser-head upon the floor to any desired extent.
A seat 11 is provided at the rear end of the platform of the machine. Seated upon this the operator by means of his feet can propel the machine across the floor while the dresser-head is in motion and thus impart the desired finish.
Other abrading means may be substituted for the sandpaper as may be found best for any particular job.
Evidently various changes may be made in my device such as will still lie within the meaning of the appended claims.
Having thus described my invention, I claim:
1. In a flooring dressing machine the com bination of a wheeled platform including an upright frame, a vertically disposed shaft journaled on the latter, means to drive the shaft, a part-shaft carried by and slidable upon the said shaft and rotatable therewith, a dresser head carried by the part shaft to engage the floor, a member in engagement with and for yieldingly supporting the part shaft, a hand lever, a support to which it is pivoted, and a member interposed between the lever and the first said member.
2. In a flooring dressing machine the combination of a wheeled platform including an upright frame, a vertically disposed shaft I journaled on the latter, means to drive the shaft, a part shaft carried by and slidable relative to and rotated by said shaft, a dresser-head carried by the part-shaft, a member in engagement with the part-shaft, means to yieldingly support said member and the part-shaft theret-hrough, a lever, and
a device interposed between the lever and the member and in engagement With each and adapted to depress the member and part-shaft by pressure on the said lever.
3. In a flooring dressing machine the combination of a wheeled platform including an upright frame, a vertically disposed shaft journaled on the latter, means to drive the shaft, a part-shaft carried by and slidable relative to and rotated by said shaft, a dresser-head carried by the part-shaft, a member in engagement with the part-shaft, means to yieldingly support the member and the part-shaft therethrough, a lever, a device interposed between the lever and the member and adapted to depress the member and part-shaft by pressure on the said lever and a grasping member mounted on the frame above the lever to aid the hand and steady it when in the act of depressing the said lever.
at. In a floor dressing machine the combination of a wheeled plat-form including an upright frame, a vertically disposed shaft journaled on the frame, means to drive the shaft, a part-shaft carried by and slidable relative to and rotated by the shaft, a dresser-head carried at the lower end of the part-shaft, a member in engagement with and for supporting the said part-shaft, the latter being carried between the ends of the members, a spring at each end of the memher to yieldingly support the member and the part-shaft, alever, and a device interposed between the member and the lever adapted when pressure is applied to the latter to depress said member and the part shaft.
In testimony whereof I affix my signature, in presence of two witnesses.
