WINDOW -SI-IADE .ADJUSTER.

Specification of Letters Patent.

Patented Apr. 9, 1912.

Application filed June 10, 1910. Serial No. 566,141.

To all whom t may concern.'

.Be it known that-I, HARRY M. SCHLOSS, a citizen of the United States, and resident of borough of Bronx, in the city and county of New York and State of New York, have invented certain new and useful Improvements in IVindow- Shade Adjusters, yof which the following is a specification.

There are certain well founded objections to securing a window shade to the casing of a window in any stationary position. If it be at the top as is customary, to shut out the light from the lower part of the window requires that the whole window shall be covered. If the shade be secured to the bottom of the sash, the same is true if it is desired to darken the top of the window, in addition to this dust, dirt and moisture gather upon the shade if it be low down on the sash, and soon ruin it.

Many times it is found expedient to furnish two shades for each window, sometimes they are secured one at the bottom of the sash and one at the top, but as this arrangement does not lend itself to the best adjustment for ventilation, the shades, when two are supplied are more often secured to the sash at about mid-height.

All arrangements of double shades secured permanently tothe sash have their disadvantages either in the high iirst cost, or in the destructiveness of the arrangement, or in the awkwardness of the positioning and I have attempted to devise a means for securing the advantages of a shade placed in any position upon a sash while using but a single shade and I have endeavored to overcome the disadvantages of a shade secured to any part of a sash by making my shade adjustable with means for securing it at any point upon the sash within a wide range.

The advantages, the principle of operation, the method of construction and a detailed description of the parts will appearl as the specification advances.

The following is what I consider the best means of carrying out this invention.

The accompanying drawings form a part of this specification, in which:

Figures 1 and 2 are in elevation, they show my device in use and include a sash, a window, and a shade designed to cover the window. Fig. l shows the device extended, the shade is at the top. In Fig. 2 the device is shown compressed; the shade is partly lowered, and the top sash is correspondingly lowered. The remaining figures are on a larger scale. Fig. 3 is a side elevation corresponding to Fig. l, showing one part of the apparatus partly in vertical section. Figlisapart removed. Fig.5shows in detail my whole device; it is in front elevation, as the device may be sometimes used. Fig. 6 is an additional part, designed to be used as occasion requires.

Similar letters of reference indicate like parts in all the figures where they appear.

I will describe my invention as applied toene of the more ordinary types of window and in the drawings, A indicates the top of the frame, A1 the left hand side, A2 the right side, and A3 the bottom or sill. The upper half of the sash is indicated by B and the lower half by B1.

The two cylinders and pistons operable therein may be considered as perhaps the most important members of my device, but as they are similar in all respect-s I will describe but one in detail though indicating the corresponding parts by separate reference letters.

Referring to Fig. 3, C and D indicate the barrel or inclosing casing. It is a section of tubing, brass or iron or even a fairly light weight tin may serve as this casing is subjected to n0 strain and performs no mechanical function. Sockets C1, C2, D1, D2, receive the tubes C and D respectively and secure them in their proper position. The sockets C1, C2, D1, D2 are each provided with an ear turned at right angles to the axis of the socket and screw holes in these ears provide means for securing them in place upon the frame of a window. Fach of the sockets has a hole centrally bored through its longitudinal axis and rods E and F are provided which are of diameter suflicient to allow them to reciprocate freely in the axial holes in the sockets through which they must pass. A collar El is secured to the rod E at a point about one third of its length from the upper end and a screw-thread is produced upon the upper end of the reciprocating rod. I provide two blocks G and H each of metal in shape approximating a cube. Each' provided wit-h a cylindrical downwardly extending part G1, Hl and each provided with an upwardly `extending tongue G2, H2. A rod J screw-threaded at both ends is secured into holes pro-perly bored and capped in the blocks G and H. This rod is of any desired length though it should correspond closely to the length of the roller upon which the shade is mounted. A collar J1 secured at mid-length of the rod J is provided with an eye J 2 into which an operating chain J3 is fixed and the lower end of the chain J 3 is provided with a ring J 4.

A pair of window shade brackets quite similar to those in use though lacking the right-angled base customarily produced upon these brackets, are provided and one, the right hand bracket having a central perforation is secured to the lip G2 of the block G. The second bracket of the pair, the left hand bracket which is provided with a slot extending inward from the periphery to the center is secured to the lip H2 of the block H.

So far I have but described the details of the construction of my device, now I will describe the mode of assembling and the mode of operation. One end of the tube C is inserted into the socket C1 and a long coinpressible spring L is inserted into the tube and rests against the bottom provided by the socket C1. When first introduced without compression the spring L is somewhat longer than the tube C, next the plain end of the rod E is passed through the helix formed by the spring L and the then lower end of the rod E is caused to pass through the axial hole in the socket C1. By this time the collar El on the rod E is in contact with the upper end of the spring and any further downward motion of the rod will cause the collar to compress the spring. rlhe second socket C2 is nowplaced in position by being strung, by means of its central longitudinal hole, upon the rod E and when it has been lowered to a sufficient extent, the tube C is inserted into the socket end. The screwthreaded end of the rod E is now projecting upward above the socket C2, and the downwardly extending part G1, which is formed integral with the block G is screwed upon the screw-threaded rod E. It is preferable that the shade bracket G4 be riveted to the tongue G2 before the whole device is assembled as it can be done with greater facility at that time.

So far in the assembling of the device I have described but one half of the complete apparatus but it is obvious that t-he assembling of the ot-her, the left half, is accomplished in an exactly similar manner except that the block H is first screwed upon the rod J, and the rod J is then screwed into the block G. The junction between the rod F and the block H can be then easily formed by turning the rod F sufficient to screw it into the projection H1 of the block H. The complete device is now assembled and is ready for useful operation, it is applied to a window at about mid-height thereof, by means of wood screws passed through the lugs extending two up and two down from the sockets of which they are a part. A window shade is now placed in the upwardly extending brackets which will be found now properly placed to receive'it and the whole. is complete.

When it is desired to lower the upper sash for the purpose of ventilation, at the same time screen a portion of the window, draw t-he shade to the proper extent, lower the sash, and pull down on the ring J t. Suit-able means should be provided for restraining the extensive action of t-he springs L, and I have tapped into the lower sockets C1, D1 a thuinb-nut O, which when screwed into their full extent pinch the rods E and F and hold them against movement.

Modiiications may be made within t-he scope of the appended claims without departing from the principle or sacrificing the advantages of this invention.

In Fig. 6 I have shown an additional part, it is a bracket designed to hold an extra shade, when it is desired to have more than one shade to a window by the use of this bracket, both of the shades are made adjustable.

It is obvious that the size of this device as well as the strength of the spring can be varied to a great extent. Other means than the thumb-screws O can be provided for restraining the action of the springs.

Having carefully and fully described my invention, what I claim and desire to secure by Letters Patent is:

1. In a window shade adjuster, a plurality of cylinders, plural supports for each said cylinder, a guide rod extending through each said cylinder and beyond the end thereof, a piston secured upon each said guide rod and operable in said cylinders, means urging said piston to the full extent of its motion, means attached to said pistons for supporting a window shade and means formed in one of the supports for each said cylinder and operable upon said rods for securing said rods in any predetermined position.
