FLOOR-DRESSING MACHINE- Specification of Letters Patent.

Application filed July 20, 1903. Serial No. 166,395.

Patented May 15, 1906.

To all whom it may concern:

Be'it known that I, CYRA B. WATTLEs, a citizen of the United States, residing at Providence, in the county of Providence and State of Rhode Island, have invented a new and useful Improvement in Floor-Dressing Machines, of which thefollowing is a specification.

This invention has reference to an improvement in floor-dressing machines used for surfacing, finishing, and polishing wood floors.

In the use of floor-dressing machines on wood floors it is essential that the weight or pressure of the dressing-roller when covered with an abrasive material, such as sandpaper, should be adjustable. When the floor is of soft wood, such as ine, the pressure of the dressing-roller shou d be less than that required when the floor is of hard wood, such as oak or maple.

In the use of the machine for polishing the floor the roller is covered with a polishing material, such as a cloth having a loop pile or nap. When the machine is used for polishing, it is im ortant that the roller should be adjustable om the floor so that the pile or gap of the cloth only is in contact with the cor.

The object of my invention is to improve the construction of a floor-dressing machine whereby the pressure of the dressing-roller on the floor is adjustable, the dressing-roller is ad ustable from the floor when used 1n polish- 1n the belt connecting the motor of the machine with the dressing-roller is adjusted, and a more compact machine is constructed.

My invention consists in the eculiar and novel constructionof a floorressing machine having mechanism for adjusting the ressure of the dressing-roller on the floor,

or adjusting the roller from the floor when used for polishing, and for adjusting the motor on the frame of the machine, to adjust the belt connecting the motor with the dressingroller, as will be more fully set forth hereinafter.

Figure is a side view of my improved floor-dressing machine in its operative osition on the floor. Fig. 2 is a plan view 0 the improved floor-dressing machine, showing the motor adjustably secured on the frame of the machine. Fig. 3 is an enlarged sectional Vlew taken lengthwise through the machine, showing the motor and handle broken away. Flg. 4 1s a transverse sectional view taken on its lower en line X X of Fig. 3, showing the adjustable axle supporting the wheels at the rear of the machine. Fig. 5 is a detail view showing the means for adjustably securing the axle in the frame to vary the wei ht or pressure on the dressing-roller; and Fig. 6 is a detail view, partly in section, or the end of one of the forward arms for supporting the dressing-roller, showin one of the rubber buflers secured in the end of the arm to prevent the machine when in use from injuring the base-board of a room.

In the drawings, a re resents the frame of the machine, sup orte on'the floor by the wheels I) b and t e dressing-roller c; d, the hollow T-sha ed handle, pivotally secured at to the frame; 6, the flexible electric cable, connecting with the handle; f, the electric motor, ad ustably secured to the frame; g, the belt connecting the motor with the dressin -roller, and h the adjustin -caster for a justing the dressingroller om the floor when used for polishing. The frame a has the sides a. a extending outward at the-front to form the arms a' (L in which are the bearings a a for the shaft of the dressing-roller c and the cavities a a in the ends of the arms for the rubber buflers a a In the sides a, a of the frame are the elon ated openin s a a, and extending outwar from the si es at the ends of the 0 enings are the lugs a o for the adjusting-b0 ts a a) 1n screw-thread engagement with the lu s. The wheels I) b are rotatably secured on the ends of the axle b, which extends through the openings 0,? a in the frame and is adjustably secured by the bolts a a The dressing-roller c is covered with an abrasive or polishing material, such as sandpaper or cloth, and is revolved by the pulle c on the outer end of the dressing-roller sha t c in the bearings a a.

The electric motor with the ulleyf has the base f 2 with the s ots f 3 f 3 a justably secured to the frame a by the bolts f 4 f extending through the slots into the frame a. The motor is adjusted lengthwise on the frame a by the adjusting-bolts a, a, in screwthr'ead engagement with the lu s a a (forming a part of the frame a) an engaging with the base of the motor. The motor f is preferably a self-contained motor, such as an electric motor, and derives its ower from a source of electric energy throug 1 the wires in thelflexiblc cable 6: These wires extend downward through v the hollow T-shaped handle (1, connecting with the switch 61, placed on the handle in a convenient position or the operator and leaving the handle near its lower end through the aperture d connect with the motor f in the usual way. The motor has sufficient ower to revolve the dressing-roller on the oor at a high rate of speed through the pulley f, the belt g, and the pulley c on the dressing-roller shaft, while the operator moves the machine on the floor by t e handle (1, the lower end of which abutting against the framework of the machine below the point of pivotal connection thereto enables the operator by de ressing the handle, to lift the dressing-roller om the floor when desired. The adj usting-caster it has the screwthreaded'stem 72/, extending upward through the cylindrical boss a, forming a part of the frame a, and is adjustably secured in the boss by thenuts MW in screw-thread engagement with the stern h of the caster.

The pressure required on the dressingroller 0 is secured by adjusting the position of the wheels I) b lengthwise of the machine, bringing the weight of the motor 7 more or less on the dressing-roller. The tension required on the belt 9 is attained by adjusting the motor 3 on the frame a, and the roller 0 is adjuste' when used for polishing by adjusting the caster h to engage with the floor and raise the roller fromthe floor the distance required, the machine now being su ported on the wheels I) b and the caster h.

t is evident that any well-known means for transmitting power from the motor to the dressing-roller could be used and that any form of motor having the adaptability may be used without materially affecting the spirit of my-invention.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. In a floor-dressing machine, a motor transmitting power to a dressing-roller, and means consisting of mechanism for adjusting the weight of the machine horizontally with the shafts of the motor and respect to the dressing-roller to put more or less Weight on the dressing-roller to vary the pressure of the dressing-roller on the floor,
