This invention relates to floor cleaning machines of the type embodying a carriage and an operating mechanism therefor, and has for its object to produce a comparatively simple, inexpensive device of this character which may be utilized for scrubbing, oiling or polishing the floor, one wherein the scrubbing, oiling and polishing devices may be readily interchanged to adapt the device for properly performing its various functions, and one in which the floor treating device employed in the machine will be positively and effectually operated.
A further object of the invention is to provide a device of this character in which the operating mechanism will drive the carriage at a comparatively high rate of speed proportionate with the speed of travel of the machine, one in which the carriage will be properly reciprocated during the scrubbing oiling or polishing operations, and one in which the brush or polisher is securely but detachably engaged with the carriage to permit convenient interchanging of said devices.
For a full description of the invention and the merits thereof and also to acquire a knowledge of the details of construction of the means for effecting the result, reference is to be had to the following description and accompanying drawings.
While the invention may be adapted to different forms and conditions by changes in the structure and minor details without departing from the spirit or essential features thereof, still the preferred embodiment is shown in the accompanying drawings, in which:
Figure 1 is a side elevation of a machine embodying the invention and showing the same equipped with a scrubbing brush. Fig. 2 is a side elevation partly in vertical longitudinal section, the section being taken on the line 22, of Fig. 3, the full lines showing the carriage at the limit of its rear movement and the dotted lines showing the carriage at the limit of its forward cover being broken away. Fig. 7 is a front view of the brush and clip showing the carriage and its supporting frame in section on the line x-x of Fig. 1, the parts be ing illustrated on a larger scale. Fig. 8 isa detail perspective view of the clip. Fig. 9 is a detail perspective view of the body portion of the carriage showing an end piece, the latter being separated from said body. Fig. 10 is a detail perspective view of a pair of oiling brushes and the oil tank and oil distributor cooperating therewith. 11 is a transverse sect on of the parts shown in Fig. '10 on the line yy. Fig. 12 is a detail perspective view of the front portion of the supporting frame of the carriage and adjunctive parts. Fig. 13 is a perspective view of the polishing device, or head.
Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.
Referring to the drawings, it will be seen that the frame of the machine includes a pair of rear side members, or bars 1 arranged to diverge relatively from their rear toward their forward ends, at which latter they terminate in vertically depending portions 2 and at their rear ends in downwardly and forwardly inclined parallel portions or arms 3, the bars 1 being provided at their rear ends with sockets 4, to receive the forward ends of handle bars 5 connected at their ends by a cross piece 6.
Fixed at its endsin the socket portions of the side bars 1 is a shaft 7 on which is rotatively mounted a drive wheel 8 designed to travel over the floor or other surface and provided on the inner face of its rim with two sets of gear teeth 9 disposed respectively at opposite sides of the centrally arranged spokes 10 and adapted to mesh with gears 11 journaled upon stub shafts 12 projecting inwardly from the lower ends of' the arms 3, the gears 11 being in turn in mesh with pinions 13 fixed upon the inner ends of shafts 14 equipped with crank arms 15 provided with wrist pins 16 on which are pivoted the rear ends of pitman rods 17 in turn connected at their forward ends with a carriage 18 which will be fully hereinafter described. The drive wheel 8 and pinions 13 may be fitted with ball bearings adapting them for free rotation.
The supporting frame-work for the carriage is preferably located in front of the drive wheel 8 and cornprises similar side members which are transversely connected, each side bar comprising an upper longitudinal bar 22 and a lower longitudinal bar 24, said bars being connected at their rear ends to the respective frame members 1 in any convenient and substantial way. The bars 22 and 24 of each side bar have a parallel arrangement and preferably comprise parts of a single bar or rod which is doubled upon itself and secured at the closed end of the pendent portion 2 of the frame bar 1. The said supporting frame-work for the carriage is provided at its forward end with U-shaped front piece, the head comprising vertical side members 20 and an upper connecting member, or bar, 21, said head having the front ends of the bars 22 W124 detachably connected thereto, whereby provision is had for removing the carquired. .The front ends of the longitudinal rods are reduced and threaded as indicated at 23 and receive nuts 25. The lower ends of the vertical side members 20 of the head piece are forked and receive supporting wheels 26 which are adapted to travel upon the floor, or other surface, upon which. the machine operation.
It is observed that the parts are so proportioned as to may be placed for cause the rods 22 and 24 to extend about parallel with the surface upon which the machine may be operating, thereby causing the brush, polisher or like device, to operate upon the surface with equal pressure and effectiveness throughout its entire travel both upon the forward and rearward stroke.
The carriage comprises a body 27, end pieces, or plates, 28 and guide rollers 29, the latter being grooved in their outer edges to receive the rods 22 and 24. The body portion 27 consists of an angular bar, or plate, arranged with one wing horizontal and the other wing vertical. The horizontal wing hasa longitudinal opening a to admit of oil or other liquid being supplied to the brush, or other means for spreading or distributing the same upon the surface, or floor, to be finished. The vertical wing constitutes a stop against which the head of the brush, or like part is clamped. 'Projections are formed at opposite ends of thbody preferably in line with the horizontal wing and comprise angular, portions b and roundedportions c. The angular portions 1) are adapted topass through angular openings e of corresponding shape, provided centrally of the end pieces, or plates, 28 so as to prevent relative rocking movement of the parts 27 and 28. The rounded portions 0 receive the lower forward ends of the pitman rods 17 which are mounted thereon. Each of the plates 28 is provided at, or rear, opposite ends with a grooved wheel 29 which is rubberfaced, or otherwise clothed to prevent rattle and noise while the machine is in operation.
A tank 31 is supported upon the front portion of the frame and is adapted to be closed by a suitable cover f which is hinged thereto at one edge and is secured at its opposite edge by means of a catch. The lower rear portion of the tank is preferably made rounding, whereas the front side is straight and'provided with a series of rows of openings 32 for the escape of water to moisten the brush and floor in the scrubbing operation. The lowest row of openings are small and the next row are a trifle larger, and the openings of the row above are still larger. By having the openings thus graduated, the flow of waterm'ay be regulated by means of aslide 33 which is mounted in suitable guides formed in the ends of the Suitable hooks g are provided at the lower forward portion of the tank to engage with the cross-bar 21 of the II-shaped head piece and retain the tank in place, said hooks admitting of the tank being readily removed when required for any purpose.
The scrubbing brush 34 may be of any construction and is adapted to be secured to the carriage in any manner to admit of its removal and replacement by means of the polishing head, or oiler. v A clip 35, shown most clearly in Fig. 8, is provided for securance of the brush to the body portion 27 of the carriage. This clip consists of a plate having opposite edge portions bent in the same direction at about a right-angle, one of the bent ends being provided with a set-screw 40 and the opposite bent portion," being provided witlia series of inwardly extending teeth 41 which are adapted to enter a raised portion of the back of the brush and prevent slipping thereof as indicated most clearly in Fig. 2. The brush is adapted. to be replaced by means of a polishing head '36, the same consisting of a back simibe applied to the floor, or surface, the means illustrated in Figs. 10 and 11 are employed, .the same consisting of companion brushes '38, a tank 39 and a distributer 42. The brushes 38 are spaced apart a short distance and each is provided upon the upper side of its back with a strip 43, and between the two strips, is fitted the tank 39.
A valve controlled outlet is provided in the bottom of the tank for the escape of the oil, or other liquid, in regulated quantity, the outflow being controlled by means of the valve which may be opened more or less. The distributer 42 is a trough and is arranged between the two brushes and is approximately of V form in transverse section and is provided with a row of holes in its bottom throughout its length for the escape of the oil which is distributed by means of-the brushes. The valve controlled outlet of the tank is preferably centrally located and the distributer 38 serves to convey the oil, or other liquid, throughout the length of the brushes, whereby a uniform delivery is assured.
In the practical operation of the machine, the samev being adapted forscrubbing, the water tank 31 and the brush 34 are placed in position as indicated most clearly. in Figs. 1 and 2.
