Specification of Letters Patent.
Iatented April 16, 1907.
To a whb m it may concern:
Be it known that we, GEORGE J. KIEBLER and JOHN P. STAHL, citizens of the United States, and residents of Toledo, in the county of Lucas and State of Ohio, have invented certain new and useful Improvements in exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the figures of reference marked thereon, which form a part of this specification.
Our invention relates to improvements in floor-surfacing machines of the class particularly adapted for polishing hard or' soft wood floors, but whlch may also be used for polishing floors constructed of stone, marble, or the like.
The object of our invention is the provision of a simplified and improved machine of this class which is efficient in its operation and adapted to insure a uniform polishing or smoothing of the floor-surface operated on.
The invention is fully described in the following specification and illustrated in the accompanying drawings, in which Figure l is a side elevation of the machine embodying the invention. Fig. 2 is a front elevation of the drive-roll and one of the idler-rolls carrying the sandpaper or polishing belt with a section of the belt thereon. Fig. 3 is a top plan view of the machine with the platform of the frame removed and portions shown broken away and one sandpaper or polishing belt removed. Fig. 4 is a crosssection taken on the dotted line as w in Fig. 3, and Fig. 5 is a cross-section taken on the dotted line at w in Fig. 3 with the gearing and wheels removed. I
Referring to the drawings, 1 indicates the frame or housing of the machine, on the platthe medium of the pip fom of which is mounted the operatingmotor 2 and exhaust-fan 3, which latter has its exhaust connecting with a bag 4through Mounted transversely of theframe 1,-with the ends j ournaled in suitable hearings in the sides thereof, is the shaft 6, carrying the two drive-wheels 7 7, which are driven in the manner hereinafter described. The forward end of the frame is supported by the two caster-wheels 8 8, which are carried by the forks 9 9. These forks have their upper ends Floor-Surfacing Machines; and we do hereby to be a full, clear, and, a 'slight vertical oscil provided with vertical studs 10, which are swiveled in the cross-bar 11 near its ends, as shown in Figs. 3 and 4. The frame 1 is supported above this bar 11 by the bracket 12, which is bolted to the platform of said frame and has its central or body portion pivoted to the bar 11, as at 13, to lpermlt said bar to have atory movement relative to the frame 1, its ends being ,slidingly mounted in guides 14 on the sides of the frame for that purpose.
The direction of movement .of the machine is controlled by a steering-handle 15, which operates over a notched sector-plate 16 and is mounted on the shaft 17. shaft passes through the platform 1 and has its lower end suit-ably j ournaled in the central or body portion of the bracket 12 and is provided at such end With the forwardly-projecting arm 17 This arm has through the mediumof the links 18 with the arms 10, which project forwardly from the studs 10 on the-forks 9, to which they are fixed.
Mounted on the shaft with the drive wheels 7 is a worm-gear 19, driven by a worm 20, which carries on its shaft the reversible transmission-gears 21 21. These gears are shifted by the lever 22, which has its lower end connected to suitable shipper means through the medium of the link 23 and are driven by the bevel-gear 24 on the shaft 25, which extends through a suitable bearing in the side of the' frame 1 and carries thepulley 26 at its outer end. This pulley is driven from the motor 2 by the belt 27. The belt 28, which drives the fan 3, also asses around the pulley 26 and the drive-pul ey' of the m0- tor, as shown in Fig. 1.
Carried at each end of the frame 1 by the This connection drive-roll 29 and the two idler-rolls 30 30 is a sandpaper-belt 31. ried nearthe top of the frame by the'arms 32, which are pivoted to each side of the frame, as at 32*, and have their outer ends formed with bearings for receiving the stub-shafts at the ends of said roll. have their ends mounted in spaced relation in the two bearing-blocks 33, which are pivotally carried at the outer ends of the contiguous companion levers 34 34, which are fulcrumed to the outer sides of the frame 1 near their ends, as at 35. The levers 34 on the same side of the frame have their inner ends termimating in contiguous position and each extending under and in contact with one of The lower rolls 30 3O The drive-roll 29 is car- Ion IIO
the set-screws 36, carried by the longitudinally-disposed wings of the bracket 37 on that side of the frame. These brackets are adapted to have a vertical movement relative to the frame I 1, due to guide-pins 3S thereon projecting within registering slots in the frame, and are connected at their lower ends by the transverse bar 39, which operates within slots 40 in the frame. Projecting from the under sides of the inner ends of the levers 34 are pins 41, which operate through apertures in the plates 42, secured to the lower edges of the frame sides, and are en'- circled intermediate the plates and levers with coiled com ression-sprin s 41*, which norm ally maintain the inner ends of the levers elevated. A lowering of the inner ends and a consequent raising of the idler-rolls 30 is effected by a depression of the lever-arms 43, which are pivoted to the inner portions of the frame sides, as at 44, andextend rearwardly over the bar 39 in contact therewith. These levers connect at their rear ends to the armterminals of the vertically disposed U- sha ed member 45, which in turn connects wit 1 the foot-plate 46 above the platform 1 through the medium of the pressure-rod 47. The foot-plate 46 is pivoted to the bracket 48 on the platform 1 and carries a dog 49, which engages the toothed sector edge of said bracket. An adjustment of the levers 34 is effected by an adjustment of the set-screws 36, coacting therewith.
In order to cause both the drive and idler rolls of each set to be raised and lowered together, so as to maintain the sandpaper-belt 31 taut at all times, each lever 34 is connected near its outer end to the superimposed arm 3'2, carrying the roll 29, by the link or rod 50, which has its lower end pivotally attachedto the lever and its upper end threaded to receive an adj listing-nut and loosely projecting through an apertured car on the arm, said ear resting on the shoulder formed by the nut.
Carried by the bearing-blocks 33 intermediate each pair of idler-rolls 30 is a gravity or pressure plate 51, which bears outwardly upon the inner surface of the belt 31 at such point, and thus, in conjunction with said rolls, maintains a straight floor-engaging surface. These plates are secured to the blocks 33 by the end pins 52, which are adapted to have a loose vertical movement in the apertured ears 53 of said blocks, as shown in Fig.2. It will thus be seen that a constant ressure is maintained on the inner surface 0 the sandpaper-belt at this point.
he rear belt 31 is driven by the sprocketchain 54, which connects the sprocket-wheel 55 on the shaft 25 with the sprocket-wheel 56, carried at the end of the rear roll 29,
while the belt at the forward end of the frame is driven by the chain 57, which connects the sprocket-wheel 56 at such end with the sprocket-wheel 58, carried at the outer end of the shaft 59. This shaft extends through bearings in the frame sides and is driven by reason of the gear 60 thereon meshing with the gear'61 on the shaft, 25.

1. The combination in a floor-surfacing machine, of a frame, levers carried on opposite sides thereof, a plurality of idler-rolls carried in spaced relation by said levers at one end of the frame in position to have contact with the floor, arms ivoted to the frame above the levers, a r0 1 carried thereby, a sandpaper-belt carried by said rolls, connection between the levers and superimposed arms whereby a movement of one imarts a like movement to the other, means for driving the belts, and means for causing a simultaneous oscillation of the levers.
