Application filed April 13,1896. Serial No. 587,302, (No model,)

To all whom it may concern:

Be it known that I, Charles C. A. BaherCAMPER, residing at Omaha, in the county of Douglas and State of Nebraska,have invented 5 certain useful Improvements in Sash-Fasteners ; and I do hereby declare that the following is a full, clear, and exact description.of the invention, such as will enable others skilled in the art to which it appertains to make and use io the same, reference being had to the accompanying drawings, which form a part of this specification.

This invention has relation to a new and improved sash-locking mechanism, the object 15 of my invention being to provide a sash-lock which at the same time shall embody a means whereby the sash can be locked practically air-tight, so as to eliminate the necessity of using weather-stripping.

In the accompanying drawings, Figure 1 shows an end view, with parts removed and broken away, of the window-frame equipped with my improvement. Fig. 2 shows a broken front view thereof with parts removed. Fig.

3 shows a front view, disclosing the arrange. meat of the locking-levers. Fig. 4 shows a top view of one side of the Avindow-casing, disclosing the arrangement of the operating effects. Fig. 5 shows an enlarged detached 30 detail with parts removed. Fig. 6 shows an enlarged top view of the operating-handle. Fig. 7 shows a front view of one of the cleatcarriers. Fig. 8 shows an end view thereof.

Similar letters and numerals of reference 35 refer to corresponding parts throughout the drawings.

The aim of my invention is to provide an air-tight, dust-proof window which shall be arranged and adapted to be locked at any 40 point.

My invention comprises, essentially, a movable cleat,which cleat is adapted to form part of the window-framing and be adjustably clamped against the window adjoining which 45 said cleat works when said window is closed,or it may comprise a controllable cleat adapted to be movably held within the window-sash proper and be clamped or bound against the window-frame, as may be desired.

Referring now to Fig. 1, A represents a suitable window - frame which is provided upon one side with four cleats, (marked 1, 2,

3, and 4.) The cleats numbered 1 and 4 are stationary and fixed to the window-frame A, as will be noticed in referring to Fig. 1, while 55 the cleats marked 2 and 3 are laterally movable and come adjacent to the upper and lower window-sashes, respectively, when said windows are in their closed position. In the method as ordinarily employed a given space 60 is permitted between the window-frames to allow a free movement of the sashes, but this method, while it facilitates the operation of the windows proper, leaves an air-space between the window sash and frame, which 65 is usually covered by a packing-strip of some kind when it is desired to provide a dustproof fitting of the window. In my invention, however, I overcome this objection in providing a laterally-working and control- 70 table cleat arrangement, so that when the window is to be opened and lowered said cleat is removed from its binding position against the window and carried away to permit the operation of the window, which, when prop- 75 erly positioned, can be secured by virtue of being impinged between the window-frame and the adjustable cleat to simultaneously form a dust-proof fitting and window-lock.

In the accompanying drawings the two 80 movable cleats 2 and 3 are provided with a cleat-carrier 5, (shown in detail in Fig·. 5,) which cleat-carrier is further provided Avith two projecting lips 6 6, as clearly shown in Fig. 8, between which lips is held a project- 85 ing shaft 7, as is shown in Figs. 4 and 5. This cleat-carrier is secured by any suitable means and they may be used either singly or in sets, as desired. Secured to the fixed cleats 1 and 4, and also to the window-framing A, 90 are the angular supporting - straps 8, (see Fig. 6,) within the rectangular portion 8' of which is held an operating stub-shaft 9, upon which shaft is fixed a sleeve provided with two outwardly-extending arms 10, between 95 and upon which is held the impact-roll 11, referring to Fig. 5. Extending from and forming part of the shaft 9 is an arm 12, which at the end is provided with a swivelcollar 13. Secured by means of a screw 14, 100 adjustably within the swivel-collar 13, by means of the screw 14, is an operating-bar 15, which below is shackled to the bifurcated end of the arm 16, which arm is secured to and

579,539 forms part of a crank-shaft 17, (shown in Figs. 1 and 6,) which shaft is provided with an operating-handle 18 and is held within the supporting-ears 19. This arrangement of instru5 mentalities would comprise my principal invention. Should a window equipped with this improvement be required to be raised or lowered, the operating-handle 18 would have to be thrown in such a position as to carry io upward the operating-bar 15, which upward movement would carry with it the arms 12, so as to carry away the impact-roll 11 from the movable cleat 2. As this cleat, however, is secured to the impact-roll by means of the 15 cleat-carrier 5, this movable cleat is carried away from the window-sash C, so that said window can be operated, it being of course understood that this impact-roll 11 travels in the path of an arc, while the movable cleat is 20 carried laterally, riding upon the fixed cleat below it or against the fixed cleat above it, according to which of the cleats is operated. Whenever it is desired to lock the windows it is simply necessary to work the operating25 handle 18 so as to draw down the rod 15, so that the window will be impinged between the movable cleats 2 and 3 and the windowframe upon the opposite side.

To further insure a practical air-tight fit30 ting, I provide the movable cleats with the packing-strips 20, which of course can be used upon all sides of the window and can be of rubber, felt, or any other suitable material.

The second part of my invention comprises 35 a method of securing the windows D and D' to the cord 21, which is made to pass over a suitable pulley 27, so that as the lower window is raised the upper is lowered a corresponding distance, it being understood that 40 both the adjustable cleats 2 and 3 are simultaneously actuated. It should, however, be understood that the windows could be arranged to be raised or lowered independently.

To provide a take-up mechanism to com45 pensate the lengthening of the connectingstrand securing the two window-sashes, I provide the lower sash with a pintle, to which said strand is secured, a pintle which upon the outside is provided with a slot adapted 50 to receive a screw-driver, and, further, has a ratchet 50 working in conjunction with an ordinary pawl, so that said strand can be shortened, so that when the lower windowsash finds its secure seating the upper win dow-sash is tightly held against the upper 5^ part of the window. The devices are noticeable because of their simplicity of construction ; and now,
