-SASH LIFT AND FASTENER.

SPECIFICATION forming part of Letters Patent No. 597,199, dated January 11, 1898. Application filed May 24,1897. Serial No- 637,954. (No model.)

To all whom it may concern:

Be it known that I, KARL AUGUST Know, a citizen of the United States, residing at Butte, in the county of Silver Bow and State of Montana, have invented certain new and useful Improvements in Sash Lifts and Fasteners; and I do declare the following to be a full, clear, and exact description of the invention, such as will en able others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in that class of spring sash-lifts which are adapted to serve the additional function of sashfasteners; and its novelty and many advantages will be fully understood from the following description and claims when taken in conjunction with the annexed drawings, in which* 1 Figure 1 is a front elevation of a Window casing and sashes equipped with my improvements. Fig. 2 is an enlarged detail elevation of one of the lifts and fasteners and a portion of its rack, the latter and the sash to which it is connected being in section. Fig. 3 is a transverse section taken in the plane indicated by the line y y of Fig. 2, and Fig. acomprises disconnected perspective views of the several parts comprised in one of my improved lifts and fasteners.

In the said drawings similar letters designate corresponding parts in all of the several views, referring to which A indicates a window-casing. B 0 indicate the lower and upper sashes arranged therein.

D indicates rack'bars connected to the inner sides of the side stiles of the casing and adapted to be engaged by the lifts and fasteners of the lower sash B.

E indicates rack-bars connected to the inner sides of the side stiles of the casing and adapted to be engaged by the lifts and fasteners of the upper sash O, and F indicates my improved sash lifts and fasteners, of which preferably four are employed, those of the lower sash being connected to the face of the same at its lower corners by screws or the like, while those of the upper sash are arranged at thenpper corners thereof. These lifts andfasteners are similar in construction, and therefore a description of the one shown in detail will suflice for all.

The casing of the lift F may be of any suitable construction, but I prefer to have it comprise a body-plate a, which is designed to be connected to the face of a sash and is provided 5 5 with an annular flange b and a cover-plate c, which has a flange d connected to the bodyplate CL by screws or other suitable nieans and also has a portion of said flange cut away to afford an opening 6 for a purpose presently described. In these plates 0. c is journaled a central arbor f, and between them are arranged a coiled spring g, a wheel 7L, a ratchetwheel '5, and a flat disk j, all of which are shown in detail in Fig. 4. The coiled spring g is nested within the annular flange Z) of plate CL and has its outer end connected to said flange and its inner end connected to the arbor f, whereby it will be seen that when the arbor is rotated in one direction to wind the spring and is then released the spring will operate to rotate said arbor in the opposite direction. The arbor f has a collar-flange 7.: to bear on the central portion of the spring g, and a circular portion Z, contiguous to said 7 5 flange k, on which the wheel h is mounted, and it also has the angular portion on to receive the ratchet-wheel i, and thecircular portion it, which latter extends loosely through the disk j and cover-plate c and terminates in a square end 13, designed to seat a windingkey (not illustrated) for a purpose presently described. 7

The wheel h is provided with an inwardlydirected marginal flange a", which snugly receives the flange b of plate a and has teeths on its outer side to engage the teeth of the rack, and said wheel also has the outwardly directed flange t, as shown. To this flanget is connected one end of a spring 16, which bears at its opposite end against a pawl 11, which is pivoted on the wheel h and is designed to engage the ratchet-wheel t, as will be presently described. The disk 3' is interposed between the cover -plate 0 and the 5 ratchet-wheel i, which is greater in thickness than the width of flange t, and it is designed to be engaged and pressed against the ratchet- Wheelt' by the screw 10, which extends through a threaded aperture in plate 0 for a purpose I00 presently pointed out.

After the lifters F are placed on the upper and lower sashes a key (not shown) is applied to their arbors and the same are turned in the proper direction to wind the springs g. This being done the screws to are turned inwardly, so as to press the disk j against the ratch et-wheel iand thereby hold said ratchetwheel and the gear-wheel against rotation and through the medium of the latter fasten the sash against movement in either direc tion. Now if it be desired to raise the lower sash the screws w of the lifters thereon are loosened, when the springs of said lifters will rotate the gear-wheels and thereby raise the sash. When the sash reaches the desired elevation, it may be fastened at such a point by simply tightening the screws w.

It follows from the foregoing that when the sash is lowered the springs of its lifters will be rewound and made ready to again lift the sash.

The lifters on the upper sash O operate in the same manner as those on the lower sash B, and in order to enable a person standing on the floor of an apartment to conveniently turn the screws to of said lifters to release or look the gear-wheels of thesame, said screws are provided with oppositely-directed lateral arms 00, (see Fig. l and dotted lines in Fig. 2,) to the ends of which depending cords y are connected, as illustrated. By drawing down on one of these cords y the operatoris enabled to turn the screw to in such direction as to relieve pressure against the disk j and release the ratchet-wheel i and gear-wheel j, so as to permit of the sash being raised or lowered, and by drawing down on the other cord y the operator is enabled through the medium of screw to to bind the disk j against ratchetwheel 2' and thereby fix said ratchet-wheel and the gear-wheel it against rotation and through the medium of the latter fasten the sash against movement in either direction.

It is obvious that when desired but one lift and rack-bar may be employed in conjunction with each sash. Iwould also have it understood that the wheel 77, may be provided with a friction-surface on its periphery in lieu of teeth, in which case the rack-bar would be dispensed with.

The disk j and screw to are desirable for fixing the wheel it against rotation and thereby fastening the shaft; but when desired other suitable means may be employed in conjunction with the lift for such purpose.

It will be seen from the foregoing that my improvements are compact and neat in appearance, and that aside from the useful purposes which they serve they enhance rather than detract from the appearance of the sashes.

Having thus described my invention, what I claim is 1. The combination of a suitable casing having the annular flange on the inner side of one of its side plates, an arbor jonrnaled in the side plates of the casing, and arranged concentric with said flange, a spring nested within the annular flange and secured at one end to the flange and at its opposite end to the arbor, a wheel loosely mounted upon said arbor and having a lateral flange of a slightly greater diameter than the annular flange of the casing and surrounding the same, and a ratchet-and-pawl connection between the arbor and the said wheel, substantially as specifled.

2. In a sash lift and fastener, the combination of a window-casing, a rack connected thereto, a sliding sash, a suitable casing connected to the sash and having an annular flange on the inner side of one of its side plates, an arbor journaled in the side plates of the casing and arranged concentric with said flange, a spring nested within the annular flange and secured at one end to. the flange, and at the opposite end to the arbor, a gearwheel meshing with the rack and loosely mounted on the arbor and having a lateral flange of a slightly greater diameter than the annular flange'of the casing and surrounding the same, a ratchet-and-pawl connection between the arbor and the said wheel,and means for fastening the sash, substantially as specified.

3. In a sash lift and fastener, the combination of a suitable casing, an arbor journaled therein, a coiled spring surrounding the arbor and connected at one end to the same and at its opposite end to the casing, a wheel loosely mounted on the arbor, a ratchet-andpawl connection between the arbor and said wheel, a disk loosely mounted on the arbor between said ratchet-and-pawl connection and one of the side walls of the casing, and a screw extending through a threaded aperture in the casing and adapted to impinge against said disk, substantially as specified.

4. In a sash lift and fastener, the combination of a suitable casing, an arbor journaled therein, a coiled spring surrounding the arbor and connected at one end to the same and at its opposite end to the casing, a wheel loosely mounted on the arbor, a ratchet-andpawl connection between the arbor and said wheel, a disk loosely mounted on the arbor between said ratchetand-pawl connection and one of the side walls of the casing, a screw extending through a threaded aperture in the casing and adapted to impinge against said disk and having the oppositely-directed latz eral arms w, and depending cords connected with said arms 00, substantially as specified. In testimony whereof I affix my signature in presence of two witnesses.
