WINDOW-WIPING- 'nnvron.

Specification' of Letters Patent.

Patented May 3, 1910.

Application filed March 4, 1907. Serial No. 360,532.

To all whom it may concern:

Be it known that I, CARL A. KELLOGG, a

' citizen of the United States, and a resident of Battle Creek, in the county of- Calhoun and State of Michigan, have invented certain Improvements in Window-Wiping Devices, of which the following is a specification.

This invention relates to certain improvements in window wiping devices, and more particularly in that class of such devices which are particularly designed and adapted for use in connection with the cabs of locomotives and the vestibules of electric cars for wiping dust, rain, frost and the like from the outer sides of the glass lights, so that the engineer or motorman may have unobstructed view of the track ahead, and the object of the invention is to provide a. de-

vice of this general character of a comparatively simple and inexpensive nature and of a strong, compact and durable construction, and which shall be capable of convenient and effective use by the engineer or motorman for wiping or cleaning the lights of the engine-cab or vestibule without in any way interfering with the performance ofcar provided with a window wiping device constructed according to my invention; Fi 2 is an enlarged fragmentary sectional detail view taken horizontally through. the window wiping device in the lane indicated by line a-a in Fig. 3 and s owing certain features of construction to behereinafter de scribed. Fig.3 is a fra mentary view taken vertically through'the ont part of the car vestibule and showing my improvements applied thereto and with the wiping arm in owered position; Fig. 4 is a view similar to Fig. .3, but showing the wiping arm adjusted to its lateral position as shown in Fig. 1, so as not to interfere with the free use of the vestibule window; Fig. 5 .is a fragmentary view of the inner end of the window wiping device, and Fig. 6 is a sectional view taken in the plane indicated by line bb in Fig. Land showing the means for holding the window wiping arm to turn with the shaft of the device. A

In these views 1 represents the vestibule of an electric railway car having a plate or frame 2 extended around its upper part and whereon the roof rests, and 3 represents the central window of the vestibule which is intended to give the motorman an unobstructed view of the track ahead. In the operation of such cars, dust, rain, frost and the like often collect upon this central front window 3 so as' to materially interfere with the view of the motorman, and being on the outer surface of the glass, such collections are difiicult of removal and are apt to give rise to accidents and errors "on the part of the motorman.

4 represents a bearing provided at the central part of the plate or frame 2 at the front of the oar vestibule, said bearing being formed, as herein shown, from outer and inner members or parts 5 and- 7, which have oppositely projectlng alined arms 8, 8, perforated for the passage of bolts 9, which are passed through the plate or frame 2 between said outer and inner members as seen in Fig. 2, so as to securely hold said parts or members in relation.

6 represents a boss extended rearwardly fromthe outer bearing member 5 and the members 5 and 7 have a bore which is extended axially through the boss 6 and 1s adapted to receive a shaft or stud 10 which is free for rotative or turning movement 111 said bore and has its forward end portion made of such a length as to-extend for some distance beyond the front of the car vestibule, its forward extremity being screwthreaded as seen at 11 to receive a nut 12 capable, by turning, of adjustment lengthwise along said shaft or stud 10.

15 is'a collar held on shaft or stud 10 at I 10 in such a way as to hold the collar to turn' in unison with said shaft or stud, while permitting .free movement of the collar in the" directionof the length of the shaft. '14 represents a spring coiled on'the shaft or stud between the collar and nut 12, I ings. By this means the detent is guided its Opposite ends having bearing upon said parts in such a way as to cause the tension of the spring to be exerted to hold the collar pressed rearwardly along the shaft and toward the front outer surface of the car .vestibule.

18 represents a tubular or hollow arm integral with. the .collar 15 and extended downwardly therefrom at an inclination to ward the glass 3 of the central window of the vestibule and 20 represents an extension adjustably held at its upper end within the bore of said arm 18 by means of a set screw 19 or the like and-having, at its lower end,

a flattened plate 21, the rear side of which has a facing or covering of cloth or other "material adapted to be pressed flush against the front or outer surface of the glass 3 0f the vest1bnle window in such a way as to form a wiper for wiping from said glass the dust, rain, frost or the like which ,may

the glass 3, so that collected dust, rain, frost. or the like may be conveniently wiped from collect thereon.

22 represents the cloth or other surface upon said plate 21.

23 represents a collar held by means of a set screw 24; upon the inner end of the shaft or stud; 10 and adapted, by engagement against the inner bearing member 7 to prevent said shaft or stud from being moved endwise and outwardly from the bore of the bearing members under the tension of wiping spring 14, and 25 represents a handle integrally produced upon said collar 23 and arranged to stand within the. car vestibule in convenient reach of the motorman, who may, on grasping said handle impart turning movement to the shaft or stud 10 in such a way as to cause the wiper carried by the arm 18 thereof, to be moved backward and forward from side to side of the outer face of the glass.

27 is a spring ressed lever extended lengthwise along t e handle 25 with its outer end adapted to be grasped by the hand andpressed by the fingers when said handle is grasped, the said latch lever being pivoted at 26 upon the handle and having its upper end bent forward to produce a detent as seen at 28, which is passed through an opening 111 the handle 25 adjacent to collar 23, and is adapted to be engaged, when said handle 25 is moved to an extreme position in one direction, as shown in Figs. 1 and 3, in a notch or seat 29 produced at one end of a ledge or flange 30 integral with the lower part of the inner bearing member 7 and extended be yond the periphery thereof in such a way as to produce at its rear side a flat surface cam faces produced upon said boss and collar, respectively and adapted, when the shaft or stud is returned to its extreme lateral locking'position, as shown in Figs. 1 and 3, to engage upon each other in such a way as to cause the collar 15 to be pressed outwardly along the shaft or stud 10, whereby when said shaft or stud stands in locked position the wiper carried by the arm 18 of said collar 15 will be withdrawn forwardly and will stand out of contact with the glass of the vestibule window. When the shaft or stud 10 is moved from its locking position,

said cams 31 and 32 will be disengaged, permitting the spring 14. to exert its tension to press the collar rearwardly along the shaft or stud 10 whereby the wiper carried by the arm 18 of the collar will be elastically pressed upon the surface of the glass to wipe the same. The tension of spring 14 may obviously be varied by adjustment of the nut 12.. y

In the operation of the device, when the glass 3 of the vestibule front shall have be- .come obscured. from the collection of dust,

rain, frost or the like upon its outer surface,-

the motorman will grasp the handle 25 and by pressure upon'the free end of the latch lever 27 will disengage the inner detent end 28 thereof from the locking notch 29 in the flange 30 of the inner bearing member 7, whereupon the shaft or stud 10 will be unlocked and may be freelyrocked back and forth to cause the wiper carried by the arm 18 of collar 15 to be wiped across the outer surface of the glass in such a way as to clean the same. The extension 20 at the lower end of arm 18 havingadjustable connection withthe body portion of said arm permits adjustment of the wiper upward or downward so that the glass may be cleaned in line with the face of the motorman and the employment of the spring it affords an elastic pressure of the wiper upon the glass such as is necessary to give the best results. After the glass has been wiped clean by the operation of the device, the handle is moved back to its initial position, whereupon the latch lever being released, its detent end 28 is pressed by its spring intowthe locking notch 29 whereupon the wiper will I be held in raised position at the side of the vestibule window so as not to obscure the view of the motorman. In returning the shaft or stud to its initial locking position, the cams 31 and 32 come into engagement and operate to withdraw the wiper from the glass so that there is no likelihood of the wiper freezing to the glass as might happenin cold weather;

From the above description it will be unwhich it may be operated without interfering in the least with the necessary duties of the'motorman, and it will be evident that the device is not limited in its application to electric railway cars, but is also capable of efiective use in connection with the cabs of locomotive engines, pilot houses of vessels, etc., without departure from the inven-' tion, and it will also be obvious that the device is capable of considerable modification without material'departure from the principles and spirit of the invention and for this reason I do not desire to be understood as limiting myself to the precise form and arrangement of the severalparts of the device as herein set forth in carrying out my invention in practice.
