WALTER S. HAVEN, OF RAOINE, WISCONSIN.

FLOOR-DRESSING MACHINE.

T 0 all whom it may concern:

Be it known that I, WALTER S. HAVEN, doctor of medicine, a citizen of the United States, residing at Racine, county of Racine, State of Wisconsin, have invented certain new and useful Improvements in Floor- Dressing Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use thesame.

This invention relates to certain improvements in floor dressing, surfacing or polishing machines; and the objects and nature of my invention t ill be readily understood by those skilled in the art in the light of the following explanation of the construction shown in the accompanying drawings to illustrate what I now consider the preferred embodiment of my invention from among other variations and arrangements within the scope of the following claims.

The invention consists in certain novel features in construction and in arrangements and combinations of parts as more fully and particularly set forth hereinafter.

Referring to the accompanying drawingsz-Figure 1, is a perspective view of one form of my floor dressing machine. Fig. 2, is a longitudinal vertical section through a floor surfacing machine showing the structure of 1, with the exception that the floor engaging tool is arranged on the sane side of the fulcrum as the lever instead of on the opposite side as in Fig. 1. Fig. 3, is a cross sectional view of the structure of 1. Fig. 4, is a perspective view of a modification. Fig. 5, is a detail perspective of a portion of the movable carrier, the loose fulcrum sleeve thereon, and a form of scraper tool carried by the sleeve. Fig. 6, is a detail perspective of a modification. Fig. 7 is a detail perspective showing a polishing or finishing pad which can be removably applied to the hand lever instead of the scraper shown by certain other views of the drawings.

The machine shown comprises means for maintaining one or more tracks or runways above and approximately parallel with the floor to be dressed, a carrier movable along said tracks, and a hand lever mounted or fulcrumed on or to said carrier and provided with a floor surfacing tool of any suitable or desirable nature or construction, whereby the operator through the medium of the lever, reciprocates the tool and applies the same to Specification of Letters Patent.

the floor with the desired pressure. The track or tracks form the backing, support or means which enables the operator to attain the lever action on the tool in pressing the same to the floor. The track or tracks is or are essential to the broad feature of my invention, whereby the leverage of the tool against the floor is attained, but the means for fixing the tracks relates to the specific features of my invention.

If preferred, the tracks might form a part of a frame work so arranged that the means employed to fix or maintain the tracks would consist of a part of the frame on which the operator could stand so that his weight would hold the tracks in place. Under this specific arrangement, my invention comprises a horizontally disposed frame provided with a fixed or movable platform adapted to rest on the floor to be dressed and designed to be manually shifted along or over any desired portion of the floor as the work of dressing the surface thereon progresses. A suitable track or runway is attached to and projects from this frame or constitutes a part thereof, and this track is arranged parallel with and a suitable distance above the floor surface to be dressed. A reciprocating carrier is confined to the track and carries a floor dressing tool or element and a hand lever whereby the carrier and tool can be reciprocated and whereby the tool is held to the floor surface with the desired amount of pressure. The operator usually stands on the platform so that his weight will hold the machine in position on the floor and against slipping or sliding during the dressing operation, although other means might be provided for this purpose. The hand lever usually extends upwardly and rearwardly so as to be readily accessible to the operator as he stands behind the machine or on the platform thereof, whereby the lever can be em ployed as a handle to reciprocate the carrier provided with the floor dressing element and at the same time as a lever to hold said element down to its work.

In the specific examples illustrated in the drawings, I provide a strong rectangular or oblong open frame work constructed of any suitable material, and at one end carrying the frame or platform 1, on which the operator can stand. This platform can be of any suitable or desirable construction and of a size to receive one or both feet of the operator. I usually mount the frame on any suitable legs or other floor supports 2, adapted to rest on the floor and hold the frame in a horizontal position and elevated from the surface of the floor although I do not wish to so limit my invention. If so desired certain or all of these supports 2, can be provided with friction or biting surfaces 20, to engage the surface of the floor and aid in holding the machine in position on the floor and against slipping during the reciprocation of the dressing tool.

In the specific examples illustrated, the spaced parallel side bars 3, of the frame form tracks or runways, and are rigidly spaced and secured together by the frame ends or cross bars 4, with the end legs 2, depending from the frame corners.

The platform 1, is shown arranged across an end of the frame and mounted on the side bars thereof. I show the platform mounted on the frame bars so as to be capable of being moved longitudinally thereof in case it is de sired to shift the position thereof for any reason, but do not wish to so limit my invention. I show each frame side composed of a pair of spaced parallel bars 3, arranged one over the other and forming a longitudinal slide or runway, although I do not wish to so limit my invention.

In the specific example illustrated, a reciprocating carrier 5, is arranged transversely of the frame between and confined to the sides thereof to reciprocate longitudinally thereof. The carrier shown consists of a strong cross bar 5, at its ends confined to said slideways by any suitable means. For instance, in Fig. 4, I show the bar 5, fixed to slides 6, confined to slide between or on the frame bars 3, while in F igs! 1, 2, and 3, I show the bar 5, carried by and forming the axle of grooved rollers 7, confined between the double frame sides to travel longitudinally thereof. A hand lever 8, is supported by said carrier which forms the lever fulcrum. The lever extends upwardly from the carrier and toward the end of the frame provided with the platform. The portion of the lever depending from the carrier is provided with any suitable floor polishing, finishing or surfacing tool.

I usually form or provide the lever with a sleeve 9, mounted on the carrier 5, and in all of the constructions shown, except the construction of Fig. 4, this sleeve is free to slide longitudinally of and turn or oscillate axially on the carrier 5. This sleeve 9, coules the lever to the carrier and enables the ever to rock vertically on the carrier as a fulcrum or center.

The inclined lower arm of the lever is usually formed by a socket 10, rigid with and projecting downwardly and radially from the sleeve 9 at an inclination to the floor, in connection with the shank 11 of the floor en- 55 gaging tool fitted removably in the socket and secured by any suitable means such as set or clamping screw 12, so that the tool can be removed for repair or sharpening or to permit application of another tool of a different form or character.

In Figs. 1, 2,3 and 5, I show scrapers of various forms consisting of inclined flat blades 13, secured to shanks 11, removably fitted and secured in the sockets 10, of the lever fulcrum sleeves or sockets 9.

In Fig. 6, I show the fulcrum sleeve 9, of the lever formed with a rigid depending lug or arm 14, to whichshank 15 of scraper blade 13, is removably clamped by U-shaped bolts 16.

In Fig. 7, I show a smoothing, surfacing, polishing or rubbing pad consisting of head 17, having the bottom rubbing surface 18, of any suitable polishin or abrading material. This pad is removabIy secured to the lever by a shank 19, clamped in socket 10. The shank being pivotally joined to head 17, by suitable means, such as eyes 20.

In Fig. 4, the lever sleeve 9, preferably oscillates on the carrier 5, but is held against longitudinal movement.

The socket 10, of the lever is shown removably receiving the shank of a forked head 21, forming the lower end of the lever and carrying a floor surfacing or polishing tool in the form of an elongated horizontal rotating wheel or cylinder 22. Any suitable means can be provided for rotating said cylinder as the carrier is reciprocated by the lever, and by rocking the lever, the cylinder can be held to or raised from the floor.

As a means which might be employed to positively rotate the cylinder, I show a toothed rack 23, secured longitudinally to one of the frame bars 3. One end of the bar 5, carries a loose pinion 24, in mesh with the rack, and this pinion 24, is fixed to a large gear 25, meshing with a pinion 26, fixed on the end of cylinder 22.

In Fig. 2, I show the lower end of the lever extended rearwardly, so that downward pressure on the handle end of the lever, moves the tool to the floor, whereas in the other figures I show the lower end of the lever extended forwardly so that the tool is held to the floor by upward pressure on the handle 1 end of the lever.

In all the structures shown, except that of Fig. 4, the lever is movable laterally, by the sleeve 9, sliding longitudinally of bar 5, so that the tool can operate over an extended area of floor, before it becomes necessary to shift the position of the frame to bring a fresh area of floor within the range of action of the tool.

If so desired the lever 3 can be formed, as shown by Fig. 6, with two upwardly diverging handle ends 8, so that two operators zoo facing each other can actuate the device. I

I do not wish to limit myself to the means shown for malntammg the reclprocatory carrier to reciprocation over the floor surface and to hold said carrier down to sustain the pressure of the lever when holding the tool to the floor surface, as various forms and ar rangements of track or guide way devices might be employed for this purpose, nor do I wish to limit all features of my invention to the employment of the tool controlling lever as the manual means for reciprocating the carrier.

It is evident that various changes and modifications might be resorted to, that parts might be omitted and other parts added, without departing from the spirit and scope of my invention, and hence I do not wish to limit myself to the exact constructions disclosed.
