SPECIFICATION forming part of Letters Patent No. 629,851, dated August 1 1899.

, Application filed December 2, 1893. Serial No. 698,077. (No model.)

To all whom it may concern:

Be it known that I, HARRY W. GLEN, a citizen of the United States, residing at St. Paul, in the county of Ramsey and State of Minnesota, have made certain new and useful Improvements in Adjustable \Vindow- Wipers, of which the following is aspecifica tion'.

This invention relates to wipers for cleaning windows, glass, and other hard surfaces; and it consists in the construction, combination, and arrangement of parts, as

hereinafter shown and described,and speciiic.

ally pointed out in the claims.

In the drawings, Figure 1 is a side elevation, Fig.- 2 is an end elevation, and Fig. 3

is a plan View, of one of myiinproved wipers complete. Fig. 4 is a perspective View of the clamping-head detached. Figs. 5 and 6 are perspective views of the two adjustable wiper-strip holders detached.

This invention relates to that class of implements used for Wiping windows and other smooth hard surfaces in which one or more strips of rubber or other similar suitable material are employed for the wiping material; and it consists of two or-moreof such wipingstrips connected to be adjusted laterally to increase or decrease the widthof the wipingsurface.

The invention further consists in the construction, combination, and arrangement of parts, as hereinafter shown and described, and specifically pointed out in the claims.

I have shown in the drawings an approved construction whereby my invention may be illustrated, A representing the head, which supports the wiper-strip holders.

The head A is formed of a strip of sheet metal bent into shape and with perforations through its sides, as shown at b, to form a means for securing the handle D, which is forked, as shown, and secured upon either side of the head A by a bolt E, as shown.

The holders for the wiper-strips consist of strips of sheet metal folded together lengthwise, with their lower portions F F closely compressed and their upper portions F F and F F distended and forming means for supporting the rubber wiper-strips G G G G".

- The handle D is curved forward, so as to bring the wiping-surfaces of the strips G G G3 G4 at a more obtuse angle to the surface to be wiped, as shown.

The parts F F are formed with their upper edges curved inward, as at d, to form a bearing against the wiper-strips, while the parts F F are formed straight, as shown.

' The parts F F are toward the front of the implement or next'the surface to be wiped, and the wiper-strips require a greatersupport on that side than on the other, and to furnish this additional support is the function of the inwardly-curved edges (1. V r

The wiper-strip holders are adapted to slide lengthwise past each other in the head A, so that the wiping-surface may be increased or decreased at pleasure. p Each of the wiper strip holders will be pro vided with a long slot (shown at e e in Figs. 5 and 6) through which the bolt E passes, so that while the holders are free to be adjusted laterally they can not be removed from the head unless the bolt be first removed. I

The handle D; as before stated, is forked 0r bifurcated, and this bifurcation is extended, as shown at g, in the form of a slit, so that when the bolt E is screwed up by the thumb-nut E the slit will permit the two members of the fork to yield, so that all the parts will be clamped firmly together and held rigidly in place. This construction of the socket for the handle, with the bifurcations and the slit g, is an important feature of my invention, as it enables the socket to be firmly clamped to the head,as well as pro viding for the firm clamping or compressing of all the parts together,and also enables the socket to adapt itself to any variation in the thickness of the head or other parts, and also provides for the taking up or tightening of the parts in event of their becoming loosened by wear or from other causes.

The cavity in the handle D for the reception of-the head A is formed with shoulders g g to support the head, so that it will not depend wholly upon the bolt E for its support.

The strip G is extended a short distance above the strip G, so that the unwiped line which would otherwise be left upon the surface being cleaned opposite to the point h of the strip G will be covered and wiped.

' but by forming one of the strips with one of its edges extended above the other this difficulty is completely overcome, as the extended surface will bridge over this unwiped surface. All the parts being of metal, no warping from change of temperature will occur. Consequently the durability is greatly increased. By this arrangement I am enabled to adapt the wiper to any required width.

In the ordinary construction it is necessary to employseveral different wipers, a separate one for each width required; but with my improved implement only one is required for all widths.

Another advantage of my construction is that the strips G G G G may be very quickly and easily removed and renewed when worn out.

Under some circumstances it may be found advantageous to use one of the wiper-strip holders separately from the headas, for instance, on the insides of show-cases and other contracted places-and with my arrangement this can easily be accomplished by removing metal of U shape in crosssection, two or more contiguous wiper-strip holders supported in said head, and capable of lateral adj ustment, and means for clamping said head and holders together, substantially as and for the purpose set forth.

2. In a window-wiper, a head of sheet metal of U shape in cross-section, two or more contiguous wiper-strip holders supported in said head and with longitudinal slots there through,a handle enclaspiiig said head, and a bolt passing through said handle, head, and the slots in said wiper strip holders,where by the whole is clamped adjustably together, substantially as and for the purpose set forth.

3. In a window-wiper, two or more holders supporting the wiper-strips and held contiguously in a suit-able head and capable of lateral adjustment therein, one set of said strips being extended beyond the other set of said strips, substantially as and for the purpose set forth.

4. In a window-cleaner, a head of sheet metal of U shape in cross-section, wiper-strip holders supported in said head and adapted to embrace said wiper-strips, a handle-socket having forked ends adapted to embrace said head, the members of said fork having shoulders g g resting upon said head and extended as bya slit g, and a clamping-bolt E passing through said fork members, head, and wiper-strip holders, whereby said parts are. clamped firmly together and provision made for taking up the wear, or adapting the socket to varying thicknesses of the parts, substantially as and for the purpose set forth.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
