DEVICE FOR RAISING OR LOWERING SWINGING SASHES.

SPECIFICATION forming part of Letters Patent No. 509,376,01ated November 28, 1893. Application iiled December 8, 1892. Serial No. 454,473. (No model.)

Y ing to be a full, clear, and exact description thereof.

My invention relates to sash raisers, and

has .special reference to a device for raising and lowering swinging sash.

The main difficulty with the sash raisers heretofore used was that they were very large and cumbersome,required long levers to operate them which generally marred or spoiled the appearance of the window. The sash usually had to be cut away to a large extent to allow the sash raiser to fit therein, and the operating lever generally pressed down'on the window sill, rubbing and marring the appearance of the same.

The object of my invention is to overcome these objections, and to provide asash raiser which is small, neat and compact in appearance, and one that can be applied to any swinging window without the employment of a long lever to operate the same, and yet one which is capable of great lifting power and strength. v

To these ends my invention consists, generally stated, in combining with a sash frame, having a plate in the window sill thereof, a sash having a sash raiser secured thereto formed of a bearing piece carried by the sash and having a pivot engaging with the plate on the window sill, a box or case sliding on the bearing piece, and anV eccentric or cam mountedin the box and adapted to move the same upon the bearing piece.

To enable others skilled in the art to make and use my invention, I will describe the same more fully, 'referring to the accompanying drawings,in which- Figure l is a plan view of a swinging sash and frame having my improved sash raiser applied thereto. ing the sash raised and in another position. Fig. 3 is a side view of my improved sash 5 raiser showing it in its normal position. Fig.

Fig. 2 is a like view show- Lt is a like view showing it in its raised position. Fig. 5 is an end view of the same. Fig. 6 is a vertical central section through the same. Fig. 7 is a perspective view of the box or receptacle. Fig. 8 is a perspective view of the bearing piece, and Fig. 9 is a perspective view of the operating lever.

Like letters herein indicate like parts in each of the views.

My improved sash raiserA is shown in the drawings as applied to the swinging sash a which is hung in the window frame b, said window frame being provided with the usual y strips c c', the strip c being on the outside of the window frame h. The ksash raiser A is shown as preferably attached to the bottom of the swinging sash a and has the bearing piece d which is pivoted at cl to the plate e on the window sill f by means of the pin d2, said pin d2 forming one of the pivots on which the swinging sash a swings.. The bea-ring piece d has the horizontal portion cl3 andthe vertical portion d4 extending up into the box or case g of the sash raiser A, said box or case g containing the mechanism for operating the sash raiserA and being attached to the swinging sash a by means of screws g passing through holes g2 in the lugs g3 on said box or case. The box or case g has an opening 1o at its bottom through which the parts enter, and a guide g4 is formed in the center of the box or case g. This guide g4 fits inl the opening d between the vertical guide arms CZ5VCZ6 on the bearing piece d and acts to guide the box or case g as it slides in'its movement in raising and lowering the sash d. In order to operate the sash raiser and move the box or case g and with it the sash @there is provided the operating lever h which has the enlarged head h for covering the box or case g, while extending out from the inner face h2 0f this enlarged head h is the pivot pin h3 which passes through an opening g5 in the guide g4 and box or case g and acts to hold the parts composing the sash raiser together, and the bearing piece dk sliding in thebox or case g forms a bearing for the turning of the lever h, while the said pin h?, isY vclinched to the back of the box or case. g. For the purpose of raising and lowering the sash athe enlarged head 71. of the operating lever h has on its inner face 712 the eccentric or cam t', the said eccentric or cam t' being formed as part of said operatinglever h. Fitting on the inner face t" of the eccentric or cam t' is the lug or pin j formed as part of the vertical guide arm d5 of the bearing piece d, while the outer face i2 of the eccentric or cam 7l bears and travels on the projecting face d7 on the vertical portion d4 of the bearing piece d. The vertical portion d4 of the bearing piece d is cut away, as at d8, so that the guide g4 on the box or case g can slide therein. The swinging sash c, has the follower 7c resting on its top; said follower 7c sliding in guides 7a in the window frame b, the said swinging sash a being pivoted at l to the follower 7c by means of the pin Z shown in dotted lines Fig. l. The follower 7c lits tightly down on top of the swinging sash a in order to prevent any air entering the apartment when the sash is closed, this follower 7c being held down on said swinging sash a by the springsm on each side of the follower 7c. The springs m lit around rods n rigidly secured to the follower 7c, while the other ends of the rods n pass loosely through openings oin the lugs or bars 0. These lugs or bars o extend out from the guides 7c in the window frame b, and the springs m being interposed between said lugs or bars o and the top of the follower 7c allow the follower to move up and down with the swinging sash. A handle h4 is provided on the end of the lever 7i, for convenience in operating.

As illustrated in Fig. l, the sash raiser A is ,shown in its normal position with the swinging sash d closed. Vhen it is desired to open the swinging sash a, all that is necessary is to grasp the handle h2 with one hand and turn the lever h to the left, when the pinj on the vertical arm d5 of the bearing piece cl will travel around on the inner face i of the eccentric or cam i until it reaches the most remote point on the eccentric or ca'mi from the pivot pin 7e on the leverh, this pivot pin k acting as a journal bearing. The outer face i2 at the Same time travels on the projecting face C17 on the bearing piece d, the pin j, inner face i, projecting face (Z7, and outer face t2, acting to raise the box or case g through the medium of the bearing piece d, and through the guide g4 contained in the box or case g sliding in the vertical guide arms d5 d6 on the bearing piece d, and so raise the swinging sash a and follower k, compressing the springs lm, against the lugs or bars o and allowing the rods n to pass through the openings o in said lugs or bars o. The swinging sash d will then be above and clear of the strip c on the window -sillf, when the swinging sash a will be free to swing on the pin d2 on the bearing piece d and the pin Z on the follower 7c. The swinging sash a can be closed and locked by swinging it back to close the window and turning the lever 71, back to the right, allowing the pin j to travel back on the inner face t" of the eccentric or cam and the outer face 'i2 on the projecting face (Z7 of the bearing piece d until the pin j reaches the nearest point on the eccentric or cam t' to pivot pin 7a2, so lowering the box or case g on the sash a through its guide g4 engaging with the vertical guides d5 d6 on the bearing piece d, and so lowering the sash a down on the window sill f. The follower 7c drops down with the swinging sash a on account of the release of pressure on the springs m, so lowering the follower with the sash.

When my improved sash raiser is in use, no air can get into the apartment when the window is closed, on account of placing the window strips on both the outside and inside of the window frame, and the follower being held tightly down on the sash. The sash raiser is easily operated and the position of the sash can be regulated and locked in any position desired. The parts composing .the same are simple, strong in their constructlon, and capable of great lifting power.

What I claim as my invention, and desire to secure by Letters Patent, is
