Application filed August '6, 1926. Serial No. 127,685.
The invention relates to improvements in floor polishers as described 111 the present specification and shown 1n the accompanymg drawings that form a part of the sam tures of construction, arrangements and combinations described; hereinafter and more particularlypointed out in the claims for novelty following.
In the drawings Figure 1 is a side elevation of the machine with the brush mounting shown in vertical section.
Figure 2 is a plan view.
Figure 3 is a cross sectional View taken on the line 33 bf Figure 2.
Lilre numerals of reference indicate corresponding parts in the various figures.
Referring to the drawings 1 is the motor which is provided with a horizontal shaft 2' projecting from one end thereof, said motor being supported at its opposite, or rear end by running gear preferably consisting of a caster 3 positioned in the transverse centre thereof, the forward end of said motor being adapted to be supported by the brush as will be described hereinafter.
4; is the brush housing which is prefer ably of substantially dome shape, circular in plan, and being provided with laterally extending parallel arms 5 adapted to receive the forward end of the motor 1 and to opposite sides of which said arms are pivoted at the outer ends thereof, as at 7, the depending wall 8 of said brush housing being suitably slotted between the arms 5 to per- -mit of the shaft 2 extending into the interior of the housing. l
The forward end of the motor is provided with a lip, or projection, 9 positioned above the shaft 2 and extending outwardly over the edge of the brush housing in spaced relation thereto so as to provide a cover for that portion of the shaft 2 between the motor and said housing.
The housing 4 is provided witha central sleeve, or hearing, 10 having a suitable closure 11 and being provided in the interior thereof with suitable means for the accommodation of anti friction bearings 12.
The brush' 13 is preferably circular in plan and 'is provided with a centrally disposed spindle 14f rotatably mounted in thesleeve 10 withthebearings 12 suitably ar} ranged there-around, said brush be ng provldedwith an annular bevelled rnn'portion 15 adapted for engagement the shaft 2,
or by a correspondingly bevelled friction elje ment 16, with, which said shaft is preferably provided, so as to provide for-the rOtation of said brush.
The spindle I4 is preferably heldwithin the bearing 10 by means of a helical spring 17 encircling said spindle above the uppermost set of bearings 12 and exerting upward pressure against a cotter pin 18. pro jected through said spindle adjacent to the end thereof. s
19 are, vertically arranged springs, of which there are preferably-two, positioned on opposite sides respectively ofthe shaft 2 connecting the motor and the, arms 5 of-the brush housing and constituting yieldable means for holding the shaft 2 in frictional engagement with the brush .13 so as to insure proper rotation of the brush at all times regardless of any variation in the vertical relationship between the motor and the brush housing.
20 is a handle having a bail shaped end extending around the top of the motor with the arms 21 thereof pivoted to the respective 7 In the use of this invention the electric connection between the source of energy and the motor is made by means of the connector 22 causing the rotation of the shaft 2 and consequently the'brush 13, after which it is simply necessary to guide the machine over the surface to be polished.
What I claim is 1. In a floor polisher, the combination with a motor having rearwardly positioned running gear, of a brush mounting pivoted to said motor, a brush rotatable in said -mounting, a shaft driven by said motor and having frictional engagement with the rim of said brush for' rotating same, and resilient means for maintaining the frictional engagement between said shaft and said brush.
2. In a floor polisher, the combination with a motor having rear running; gearand a for-= Wardly extending horizontal shaft, of a circular brush mounting having rearward extensions pivoted to opposite sides respectively of said motor, a brush rotatable insaid mounting and having an annular bevelled rim engaged by said shaft, and resilient means connecting said motor and said brush mounting for preserving the frictional engagement between saidshaft and said brush.
3. In a floor ,polisher, in combination, a motorhaving a horizontal shaft and a bevelled friction element carried thereby, running gear supporting the rear end of "said motor, acircular brush mounting pivoted to said--motor, said shaft being extended into said mounting, a circular brush rotatable in hearings in said mounting and having an annular bevelled portion adapted for engagement by said friction element, yieldable means connecting said motor and said brush mounting to hold said shaft to engagement I With said brush, and a handle.
4, In a floor polisher, in con'ibinatioma motor having a horizontal shaft, a bevelled friction element carried by said shaft, a cir cular brush housing having rearwardly entending arms pivoted to opposite sides respectively of said motor, said housing'being provided with a centrally disposed upwardly extending hollow bearing, a brush having a central spindle rotatably mounted in said bearing, said brush having an annular bevtending'arms, a brush rotatable in said l1ousing, a motor extending between said arms and having pivotal connection therewlth,
said motor including a shaft adapted to rest on the rim of said brush and constituting the means-for. rotating same, spring means holding said shaft in engagement v lth. said brush, and running gear supporting the rear end of said motor. f
v6. In a floor polisher, in combination, a
motor having rear running gear, a' brush housing having spaced lateral extensions be tween Which the forwardend of id notor pivoted, said motor having a horizontal shaft extending into said housing, a brush mounted for rotation Within said housing, said brush having an annular rim positioned in the path of said shaft, and yieldable means holding said shaft in frictional engagement with said rim.
