WILLIAM M. FOLBERTH, OF CLEVELAND, OHIO, ASSIGNOR TO THE FOLBERTH AUTO SPECIALTY COMPANY, 0F CLEVELAND, OHIO, A. CORPORATION OF 01H0.
WINDSHIELD-CLEANING APPARATUS.
Application led January 25, 1919.
To all whom t may concern.
f' Be it known that I, WILLIAM M. FoL- nnn'rH, a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Windshield-Cleaning Apparatus, of which the following is a specification.`
y invention relates to apparatus adapted to clean the windshield of an automobile or the like.
An important object of the invention is to provide apparatus oi" the above-mentioned character, which is actuated by the substantially constant partial vacuum or suction within the intake pipe or manifold of an internal combustion en ine.
A further object o the invention is to provide apparatus of the above-mentioned character which is simple in construction, inexpensive to manufacture and convenient in use.
Other objects and advantages of the invention will be apparent during the course of the following description.
In the accompanying drawings forming a part of this specification, and in which like numerals are employed to designate like parts throughout the same,
Figure 1 is a central vertical lo-ngitudinal sectional view showing the apparatus arranged on the windshield of an automobile,
gigure 2 is an end elevation of the saine,
Figure 3 is a front elevation of the apparatus diagrammatically illustrating the connection to the manifold of an internal oombustion engine.
The numeral 5 designates a windshield of an automobile of any well known or preieri-ed construction, the same including a frame 6, as is well known.
The numeral designates a tube, one end of which is rigidly attached to the. wind shield frame, as shown at 61. This end of the tube is closed, as shown. The opposite end of the tube 60 receives a plug 62 and has screw threaded engagement therewith. This plug is rigidly secured to the frame 6, as shown at 63.
The pistons 64 and 65 are mounted to reciprocate within the tube 60, forming therewith alined cylinder chambers 66 aud 67. The pistons are connected by an inner tube 68, preferably having screw threaded en- Specication of Letters Patent.

gagement therewith. This inner tube carries a cleaner bar 69 rigidly secured thereto, operating through a slot 70. The cleaner bar is .provided with a cleaner member 71 of flexible material, such as leather or rubber, operating in contact with the glass or the like to be cleaned. The pistons 64 and have lon itudinal slots formed therein, receiving a ongitudinal rib or key 73, ri idly secured to the inner surface of the tu 60 whereby the pistons cannot rotate.
The plug 62 has a main longitudinal opening or bore 74, in communication with a port 75 leading into a pipe 76. This ipe has a cutoff valve 77 connected therein. I'The pipe 76 leads to a suction or intake ipe or manifold 17 of the internal combustion engine (see Figure 3). Extending longitudinally through the opening 74 is a vacuum braking tube 78, rigidly secured to a plug 79 screw threaded within the outer end of the plug 62, as shown. The tube 78 is provided with apertures 80, as shown. The tube 78 is provided at its left end with a valve seat 81, and at its opposite end with a* valve seat 83, as shown. A chamber 84 surrounds the valve seat 81. This chamber is connected to the right hand cylinder chamber 67 by a pipe 84.
A tubular valve 86 is mounted to reciprocate within the opening 74, and preferably has a central portion 87 slidably receiving the tube 78. The tubular valve 86 is provided at its left with an enlarged head 88, to contact with the valve seat 8l and to further contact with a valve seat 89 formed upon the end of the plug 62. A hollow head 90 is rigidly secured to the opposite end of the tubular valve 78 forming therewith a shoulder 91. The shoulder 91 is adapted to contact with a valve seat 92 formed u n the lug 62. It will be seen that the hollow head) 96 forms a chamber 85, surrounding the valve seat 83.
A shifting rod 94 extends longitudinally within the tube 68 and is rigidly secured to the hollow head 90. The hollow head is provided with apertures 95. The rod 94 carries nuts 96 or other contact element, to be engaged by the piston 64 when it approaches the end of its travel. The operation of my apparatus is as follows:
When the tubular valve 86 is in the position to the left, as shown in Figure 1 and the valve 77 is opened, the suction from the intake pipe or manifold 17 will be transmitted through the pipe 76, port 75 to bore 74, chamber 84, pipe 84 and to the right cylinder 67. The piston is therefore drawn to the right while the cylinder chamber 66 is in communication with the atmosphere through ports 95, chamber 85, ports 80 and tube 78. When the piston 64 contacts with the nut 96 the shoulder 91 will engage the valve seat 83, thereby closing communication between the chamber 85 and the atmosphere. The shoulder 91 also disengaging the valve seat 92, whereby the opening 74 is placed in communication with the chamber 66. The valve 88 now engages valve seat 89 and disen ages valve seat 81, whereby cylinder 67 is p aced in communication with the atmosphere, through pipe 84', chamber 84, port 8() and tube 78. The pistons now travel to the left until the piston 64 contacts with the head 90, which restores the tubular valve to the position shown in Figure 5. It is thus seen that the operation will be repeated and is automatic and so long as the valve 77 remains open, and suiicient vacuum is maintained in pipe 76, the successive reciprocations of the pistons will reciprocate the cleaner member 71 in contact with a portion of the surface of the windshield to clean it. It is to be understood that the form of my invention herewith shown and described are to be taken as preferred examples of the same and that various changes in the shape, size and arrangement of parts may be resorted to Without departing from the spirit of my invention, or the scope of the subjoined claims.
Having thus described my, invention, what I claim is:
