MACHINE FOR DRESSING FLOORS.
To all whom it may concern:
Be it known t-hat I, SIDNEY D. HOY, a citizen of the United States, residing at Sioux City, in the county of Voodbury and State of Iowa, have invented new and useful 11nprovements in Machines for Dressing Floors, of which the following is a specification.
This invention relates to new and useful improvements in machines for dressing floors and other surfaces and it has more particular reference to a machine which is propelled over the surface to be dressed by suitable means and which includes a dressing roller or equivalent device which is driven by a system of multiplying gears.
One object of the invention is to provide a machine having a novel reversible handle providing for the manipulation of the operating parts with either the right or the left hand and so arranged with respect to the dressing roller as to provide for the movement of the latter closely alongside of base boards and into otherwise inaccessible corners.
A further object of the invention is to provide a novel construction and arrangement of means for determining the degree of pressure with which the dressing devices bear upon the surface to be polished.
lin the accompanying drawings, I have illustrated by way of example, a preferred and advantageous embodiment of the invention.
ln the said drawings: Figure 1 is a side elevation of a floor dressing machine constructed in accordance with the present invention. Fig. 2 is a top plan view of said machine. lF ig. 3 is a detail View partly in end elevation and partly in cross sect-ion of the dressing roller. Fig. 41 is a detail longitudinal sectional view thereof, and Fig. 5 is a detail perspective View of the skeleton roller frame.
Similar characters of reference designate corresponding parts throughout the'several views.
An essential ingredient of one of the novel combinations of elements which the invention presents, comprises a handle, as 1, which preferably includes a pair of spaced longitudinal bars, as 2, suitably connected. A hand grip, as 3, is secured between the upper end portions of said bars, and a bearing block, as 4L, is secured between the lower end portions of said bars and together with the latter, pivotally surrounds an axle, as 5.
Specification of Letters Patent.
Application filed .'J'nly 15, 1909.
Patented Deea 1999.
Serial No. 507,799.
The bars 2 support near their upper' ends transverse shafts 6 and 7, the latter being arranged inwardly of the former. The shaft 6 carries at one end thereof a crank handle, as S, and in the space between the bars 2 is provided with a pinion, as 9. The shaft 7 is provided inl the space between the bars 2 with a smaller pinion 10 which is driven by the pinion 9. @n the projecting end portion of the shaft 7 a sprocket wheel, as 11, and a balance wheel, as 12, are provided. A sprocket wheel, as 18, smaller than the wheel 11 and driven therefrom by a chain, as la, surrounds the axle 5.
The handle 1 is located at one side of the axle 5 and the major port-ion of the latter projects laterally from the handle and carries a skeleton roller frame, designated generally by the numeral 15 and which is illustrated in detail in Fig. 5.
The roller frame 15 consists essentially of a pair of hubs, as 16, which surround the axle 5 and which are connected by a tubular member, as 17, through which said axle passesrlhe sprocket wheel 13 is connected to t-he hub 16 which is located adjacent the handle 1. rlhe hubs 16 constitute supports for a plurality of U-shaped members, as 1S, the legs of which extend radially of and are fitted into the hubs 16, the said legs beingI connected by longitudinal bar portions, as 19, which are disposed in spaced parallel relation and are necessarily arranged to define a cylinder. The roller frame thus constructed is of especial advantage when employed in connection with a pneumatic carrier. Such a carrier is designated by the numeral 2O and is conveniently in the form of an endless hollow cylinder of suitable construction, preferably embodying an inflatable body provided with a valve, as 21, and an outer canvas wrapper, as 22.
The dressing or polishing means herein shown, consists of an outer cylindrical sheathing of sand paper, as 23, which is fitted over the carrier 20. llhe developed pressure incident to the inflation of the body causes the carrier to bind frictionally against the bar portions 19 and also against the sheathing 23, the consequence being that these several associated parts are firmly held against relative rotation or creeping. The arrangement of the bar portions 19 is of particular advantage in this connection, since said bar portions take into the material of the carrier, as shown in Fig. 3, so
as to pi'oduce intervening expanded portions of the latter which materially aid in the fi'ictional binding' action above referred to. The cari'ier is placed on the roller frame in a deflated or partially deflated condition and the sheathing is then fitted over the carrier, after which the latter is inflated to produce the binding of the parts. To remove the sheathing, the carrier may be deflated to a necessary degree. At this time the cai'rier may likewise be removed from the roller frame.
The axle 5 is provided on its end adjacent the handle l with a supporting wheel, as 2a', which is of slightly less diameter than the dressing device. As was stated, means is employed for the purpose of determining the deg'ree of pressure with which the dressing device bears upon the surface of the floor, and such means preferably comprises a bar, as 25, carrying at its end a roller 26, and a bar, as 27, carrying at its end a roller 28. The bar 25 is located forwardly of the dressing roller and is of L shape, having a longitudinal leg which carries the roller 26 and is positioned somewhat under the dressing roller' and having also a radially extending leg, the end of which is formed as a collai' surrounding and scoured to the axle 5 for pivotal adjustment tliereabout by a set screw 29. The bai' 27 also of L shape and has longitudinal and radial legs which are of greater extent than the corresponding legs of the bai' 25. The longitudinal leg of the bar 27 carries the rollei' 28 and the radial leg of said bar terminates in a collar which surrounds and is secured to the axle 5 by a set screw 30. The radial leg of the bar 25 is secured to said axle between the handle l and the sprocket wh-eel l2 and the radial leg of the bar 27 is secured to the axle between the handle l and the supporting wheel 2-l. The longitudinal legs of both of said bars terminate short of the end of the dressing device so as not to interfere with the movement of the latter closely alongside of baseboards and in corners. The angle at which the radial portions of said bars are disposed with respect to one another-detei'mines the degree of pressure with which the dressing device bears upon the surface to be polished, the nari'owing of the angle lessening the degree of pressure by raising the dressing device fi'oin the floor and the widening of the angle increasing the degree of pressure by bringing the dressing device into closer contact with the floor.
rlhe handle l, by virtue of its pivotal relation to the axle 5, may be positioned at either side of the dressing roller in order to provide for the manipulation of the crank handle S with either the right or the left Having fully described my invention, l.l
claim:
l. ln a dressing' machine, in combination, an axle, a handle pivotally surrounding one end of the axle, a gear wheel on the axle, gearing carried on the handle for `operating the gear wheel and a dressing device provided on the axle wholly at one side of the handle and the gear wheel and projecting freely therefrom, the dressing device being driven from the gear wheel and the handle being movable pivotally to a position at either side of the dressing device.
2. ln a dressing machine, in combination, a dressing roller, an axle therefor', a supporting wheel connected to the axle, a pair of angular-ly disposed bars connected to the axle for pivotal adjustment thereon, and rollers carried by the bai's.
3. n a dressing machine, in combination, a dressing roller, an axle therefor, a supporting wheel connected to the axle, a pair of angularly disposed bars connected to the axle for pivotal adjustment thereon, a roller carried by each bar, a reversible handle having an end portion pivotally surrounding one end of the axle and means for operating the dressing roller.
t. In a dressing machine, in combination,
a dressing roller, an axle therefor, a suppoi'ting wheel connected to the axle, a pair of L-shaped bars having longitudinal and radial portions, the portions of one bar being longei' than the corresponding portions of the other bai', the radial portions being connected to the axle for pivotal adjustment thereon, and rollers provided on the longitudinal portions.
ln testimony whereof I have' hereunto set my hand in presence of two subscribing witnesses.
SIDNEY D. HOY.
