Spdcification of Letters Patent.

Application filed July 25, 1916. Serial No. 111,296.

To all whom it may concern Be. it known that I, JOHN E. Homer's, a citizen of the United States, residing at San Francisco, in the county of San Francisco and State of California, have invented certain'new. and useful Improvements in Window Wipe-rs, of which the following is a specification.

This invention relates to window wipers, and more particularly to a wiping device adapted to be used for removing moisture from the outer surface of a carwindow, 'au

or similar device.

One of the main objects of the invention is to provide a wiper of simple construction and operation which can be quickly and easily applied to a car window or the like.

rther object is to provide a device of the character stated so constructed that it will wipe the Window pane on its down stroke but will not come in contact with it on its up stroke.

In the drawings V Figure 1 is a front view of the invention as applied, the supporting means and casing containing the same .being shown in section,

Fig. 2 is a section on line 2-2 of Fig. 1,

Fig. 3 is a section on line 3-3 of Fig. 2,

Fig. 4 is a section on line 4-4 of Fig. 1, and 1 Fig. 5 is a fragmentary top plan view of the invention as applied to an automobile wind-shield.

A cylindrical casing 1 of brass or other suitable material is secured at each side of the window frame 2 by means of screws 3 threaded through ears 4 formed integrally with the ends of the casing. This casing is provided, near its lower end, with two diametrically opposite apertures 5. A flanged disk 6 is secured in the casing near the lower edge thereof. This disk supports a long coil spring 7 which normally acts to hold a cylindrical sleeve 8 in raised position in the upper end of the casing. A ball 9 is mount ed in this sleeve and provided with a peripheral groove 10 in which is secured the upper end of a cable 11. This cable passes through an opening in the disk 6 and outof one of the apertures 5 at the lower end of the. casing, being passed about a grooved pulley 12 rotatably mounted on a pin 13 secured in the casing near the lower end thereof.

A rod 14 of rectangular cross section has its end portions 15 rounded and rockably mounted through diametrically opposite apertures in the sleeve 8. Each end portion of this rod passes through the center of ball 9 and is secured therein by a pin 16 which passes through the ball and the rod; This pin also serves to secure the cable 11 in'the groove 10 of the ball. A small coil spring 17 has one end secured to the sleeve 8 and the other end secured to the outer end of pin 16. These springs act normally to hold the rod 14 so that its side faces are parallel with the pane 18 of the window.

14 of the rod 14 is mounted a sheet metal casing 19. This casing is shaped to fit the rod snugly and is provided with downwardly projecting inwardly inclined flanges 20. These flanges firmly grip the triangular base portion 21 of a rubber squeegee strip 22. The casing 19 is provided, at each end, with a leaf spring 23 riveted thereto and provided on its outer end with a tapered head 23 which engages a corresponding recess in the body of the rod 14. By this means the casing is secured against longi tudinal movement on the rod. By detaching one of the rounded end portions 15 of the rod 14 from the ball 9 and removing it from the sleeve 8, the casing 19 can be readily slid along the rod by'raising the leaf springs 23 so as to withdraw the tapered head 23 of the same from the recesses in the body of the rod. To replace the casing, it is only necessary to slide the same along the rod and the spring catches will snap into place of their own accord when the casing has reached its proper position on the rod.

Normally, the small coil springs 17 act by tension to hold the squeegee strip 22 parallel with the pane 18 and in spaced relation thereto. By pulling on the cable 11 the balls 9 are rocked outward so as to bring the edge of the squeegee strip into contact with the surface of the pane to be cleaned. B further pulling on the cables, the balls 9, and consequently the rod 14 and the various elements carried thereby, are moved downward, the squeegee strip 22 being in tight frictional contact with the surface to be wiped. The squeegee strip acts in the usual manner to remove all moisture such as would obscure or interfere with the sight through the window pane. When the cables 11 are released, the springs expand and return the sleeves 8 to their normal position. Also, the

n the intermediate rectangular portion Patented July 2d, 191% tension springs 17 rock the rod 14 simultaneously with the release of the cables so as to move the squeegee strip into parallelism with the window paneand out of contact with the same, as previously described. In order to permit proper vertical movement of the rod 14 and the squeegee strip, the easing 1 is provided with a longitudinal slot 1 in its inner side. As will be readily understood from Fig. 1 of the drawings, the

rounded portion 15 of the rod which passes through the sleeve 8 forms a bearing which facilitates rocking of the ball 9.

In Fig. 5 l have shown the invention as applied to an automobile wind-shield. In this case, the ears 4 are omitted, being replaced by tl-clamps 24 integral with rings 25 which fit tightly about the casings 1. These clamps are secured firmly about the side rods 26 of the wind-shield 27 by binding screws 28 and nuts 29. The operation of the device is the same as previously described in connection with Figs. 1 to 4.

As previously stated, the springs 17 normally act to hold the squeegee strip 22 in a vertical plane parallel with the window pane .1 18 and spaced therefrom. When tension is exerted on'the cables 11 the balls 9 are rocked so as to swing the rod 14 and thesqueegee strip inward so as to bring the latter in close contact with the outer surface of the window pane. place simultaneously with the downward movement of the rod 14 and, when the cables 11 are released, thesprings act simultaneously with the release of the cables to 7 rock the rod 14 outward so as to move the This action takes of the surface after it has once been cleaned.

There may be slight changes made in the construction and arrangement of the difi'erent parts of my invention without departing from the field and scope of thesame, and I intend to include all such variations as fall within the appended claim in this application, in which a preferred form only of the invention is disclosed.

What I claim, is v In a device of the character described, the combination of a casing, a sleeve slidable in said casing, a coil spring mounted-in the casing and acting to normally hold the sleeve in IEtlSBd POSltlOIl, a rod journaled in said sleeve, a ball mounted in the sleeve and secured on the rod, a wiping device carried by said rod, a cable passed about the ball and secured thereto and passed through the casing near the lower end thereof, and a tension spring mounted in the sleeve and secured to said ball so as to norm-ally hold the wiping device in a vertical plane.

In testimony whereof I affix my signature in presence of two witnesses.

JOHN E. HOLMES. Witnesses:

ALBERT A. NossuM, CHARLES Monmnrr.
