B. DAVIS AUTOMOBILE WASHER Filed Nov. 4, 1921 FIG- 4. 2a
Patented June 26, 1923.
HARRY BRYAN DAVIS, OF HOUSTON, PENNSYLVANIA.
Application filed November 4, 1921. Serial No. 512,861.
T 0 all whom it may concern:
Be it known that I, HARRY BRYAN DAVIS, a citizen of the United States, residing at Houston, in the county of \Vashington and State of Pennsylvania, have invented new and useful Improvements in Automobile Washers, of which the following is a specification.
This invention relates to washing machines, and more particularly to a machine specia ly adapted for washing automobiles and similar vehicles.
One of the main objects of the invention is to provide a machine of the character stated of simple construction and operation which will permit freedom of movement of the washing element so as to facilitate washing of the automobile. A further object is to provide a machine in which water is pro- 'ected upon a brush or other washing memer which is rotated, the stream of water serving to remove dirt and foreign materials which are loosened by the brush. Further objects will appear from the detailed description.
In the drawin s:
Figure 1 is a side view of the machine;
Figure 2 is a detail, partly in section, of the handle and associated parts;
Fi ure 3 is a detail, partly in section, of the driving connections between the motor and the flexible driving element;
Figure 4 is a detail ofthe connections between the flexible driving member and the motor driven gear;
Figure 5 is a detail of the means for se curing a brush on the brush gear.
In constructing the machine I provide a cabinet or casing 1 mounted upon a suitably braced frame 2 which is mounted upon casters 3 so as to be readily transportable. A base plate 4 is secured upon the top of casin 1 by any suitable or preferred means. An e ectric motor 5 is secured upon this plate and may be connected by means of the usual cord to any suitable source of supply of electrical energy. The stand and the motor may be readily transported, the cabinet or casing serving to hold the brushes and other equipment used in washing automobiles.
housing is positioned between two collars 10 which are secured by set screws 11 upon shaft 7, these collars being so spaced as to prevent endwise movement of housing 9 while permitting free turning of the housmg about shaft 7. A closure plate 12 is provlded in the top of housing 9, this plate be- 111g frictionally secured in position, or secured 1n any other suitable or preferred manner. By removing the plate 12 and loosening set screw 11 of the collar 10 positioned within the housing, the housing may be moved away from motor 5 so as to disengage gear 8 from gear 6, thus permitting removal of gear 8 when desired or necessary and facilitating cleaning or repairing of the driving gears and associated parts.
A flexible driving member 13 is secured at one end, by means of a set screw 14, in a tubular neck 15 dependin from gear 8. This neck extends through an exteriorly threaded nipple 16 depending from housing 9, this nipple receiving a con ling nut 17 which co-operates with a coup in member 18 secured to the end of a fiexib e tube or sheath 19 for detachably securing the latter to the housing. At its other end sheath 19 is secured to one end of a rigid tubular member 20 forming a handle, the driving member 13 being extended through member 20 and secured at its other end to a bevel gear 21 positioned within a housing 22 rigidly secured to handle 20. Bevel gear 21 meshes with a bevel gear 23 which is rotatably mounted within the housing and is provided with a squared neck 24 which extends through the housing. The neck 24 is adapted to receive socket member 25 of a brush 26, a set screw 27 being provided in the socket member for securing the brush to member 24. This brush can be of any size or shape preferred, thus rendering it possible to use a brush which is specially adapted for washing any particular part of the automobile. A closure plate 28 is detachably secured on the top of housing 22 and is provided with a depending pin 29 which fits into a central bore in gear 23, this pin assisting in holding the gear in proper relation to gear 21.
A rigid water tube 30 is secured by straps 31 to tube or handle 20, this tube being connected at its inner end to a hose 32 which is connected to a suitable source of water supply. The flow of water through tube 30 is regulated by a valve 33 of any suitable or preferred type, and the discharge noazle 34 of this tube is positioned a slight distance in 'rear of gear 23 and is curved forwardly and downwardly so as to direct a stream of water upon the surface being cleaned closely adjacent to the brush, thus keeping the brush saturated, the water also actmg to wash off or remove the materials loosened by the brush. In practice the water is discharged from the nozzle 34 at low pressure thus rendering it possible to quickly wash an automobile without damaging the finlsh such as occurs where the water is discharged upon the surface to be cleaned at high pressure.
What I claim is 1. In a machine of the character described, a drive shaft, a housing mounted on the shaft to turn freely about the same, a
'rotatably mounted member adapted to receive a cleaning member, a flexi le driving member, driving connections between the flexible driving member and said rotatably mounted member, and driving connections between said shaft and the flexible driving member positioned within the housing and permitting movement of the same about the shaft.
2. In a machine of the character described, a drive shaft, a housing mounted on the shaft to turn about the same, a bevel gear mounted in the housing, a bevel gear secured on the-shaft and meshing with the first mentioned gear, a second housing, two intermeshing bevel gears mounted in said second mentioned housing, one of said gears being adapted to receive a cleaning member, and
driving connections between the gear mount-- ed in the first mentioned housing and the other gear mounted in the second mentioned housing.
3. In a machine of the character described, adrive shaft, a housing mounted on the shaft to turn about the same, a bevel gear mounted in the housing, a bevel gear secured on the shaft and meshing with the first mentioned gear, a flexible sheath secured at one end to said housing, a housing connected to the other end of the sheath, two meshin bevel gears mounted in the second mentioned housing, one of said gears being adapted to receive a cleaning member
