EAPFCIFIGATION forming part of Letters Patent 110 345,050, dated July 6, 1886.
Serial No. 186.054. (No model.)
To all whont it rmty concern.-
Be it k now n't-liat I, Mosns O. HARGRAVE, of WVilmington, in the-county of New Hanover and State of North Carolina, have invented a new and usefulImprovementin Sash-Holders, of which the following is a description.
Referring to the accompanying drawings, Figure 1 is a perspective view showing my device in place in a partof a window-casing. Fig. 2 is a perspective view of the device removed, part of its case being broken away to show theinncr parts. Fig. 3 is a front view of the device. Fig. 4 is a side elevation of the carrier, the side being partially broken away to show the working parts, and Fig. 5is aside elevation of the device with dotted lines to show parts when positions are changed.
The invention relates to that class of sashholders in which spring-actuated pulleys are employed to bear against the edge of the sash as a substitute for the cordsand weights.
The invention has for an object to combine with said pressurepulleys a lock which can be conveniently nianipulated to secure the sash, and to arrange such lock in the immediate carrier of the pulleys in such manner as to present no obstruction to the working thereof when the sash is unlocked.
It has for further objects other improvements, as will be explained.
The invention consists in certain novelconstructions and combinations of parts. as will be hereinafter described.
The outer or main case A is formed somewhat similar to the cases now commonly used for the guide-pulleys used in connection with balance-weights. In the sides of this case A, I form parallel slots a and a curved or segmental slot, B. I also provide the case with a series of holes, C, for the purposes hereinafter explained. The carrier D is fitted and movable within the case A, and is provided with pins or studs (1, which extend through the slots a, and. serve to guide the movement of the carrier as well as to limit the extent of such movement. These studs (1 are preferably the extended ends of the axles of rollers E, the peripheries. of which project beyond the face of the carrier and the case. A spring,
'50 F, is connected with the case and bears against the inner side of the carrier, giving the latter an outward tension. This spring is preferabl y, as shown in the present instance, a curved barspring having its ends bearing against the inner side of the carrier at the ends thereof, for which purpose the carrier is formed solid for a considerable distance from its ends to form. bearings for the spring. At its middle portion the spring is provided with earsfipro jected rearwardly from its opposite sides, and having openings for the boltG, which ispassed through one opening 0 in the casing A, thence through openings f and theopposite opening 0, securing the spring to the case.
In operation the pulleys bearing against the edge of the sash by the pressure so exerted will hold the sash in any position to which it may be adjusted and yet permit itto be easily moved up or down, as desired. The carrier is also provided with a lock, II, by which to fasten the sash. This lock is substantially a lever pivoted between its ends midway the rollers E, and having ahead, I, atone end and a handle, J, at the opposite end. has a curved bearing-face, i, usually serrated, as shown, and such face is curved eccentrically to the pivot of the lock. At or near its extremity the handle J is provided with a lat- By adjusting the bolt into different pairs of 65 The head I oral stem, which projects through the slot B. 8
By this stem the lock may be adjusted into and out of engagement with the sash. \Vhen ciently wide to permit the lateral movement 5 of such stem in the movements of the carrier. At its end b, which, for convenience of referenceI term its rear end, the slot is extended to permit the inward movement of the stem when thehead is pressed against the sash.
In order to prevent the lock-handle from striking the roller when such lock is adjusted IOO out of engagement with the sash, I employ the stopplate L, which projects partly over the inner face of the roller, as shown. This plate is preferably provided with an extension, Z, fitting around a cross-pin, M, and is supported on the crown of a bail or staple, N, the arms a of which are supported on the pivotal pin of the lever-lock.
In the use of myinvention the case and contents are placed in thesash-channel of the window-case at a point at or nearly opposite the meeting'rail of the sash, and the stem of the le verhandleextends into the room through aslot,
K, formed in the window-casing, said slot being curved concentrically with slot (t to permit the movement of the stem necessary to adjust the lock into and out of engagement with the sash.
It is usual to employ two holders with each sash; but only one o'fsuch holders is provided with a lock.
The invention is much easier applied than the pulley and weight commonly used, can be used with any ordinary window-frame, and, in addition to supporting the sash at any desired point, prevents all rattling of the sash in the frame.
Having thus described my invention, what I claim as new, is-
1. In a sash-holder, the combination of a carrier provided with rollers, a spring supporting said carrier, and a lever-lock ad justble into engagement with the sash and sup ported in the carrier, whereby when the lock is engaged with the sash the rollers will be held clear thereof, substantiallyas set forth.
2; A sash-holder comprising a carrier, rollers therein, a lever-lock, a stop-plate, L, having an extension, Z, a bail or staple, N, and a spring engaging the carrier, substantially as set forth.
3. In a sash-holder, the combination of the case having a series of holes, 0, the carrier, the bar-spring having its ends engaging said carrier, and the bolt connected centrally with said spring and adjustable into any desired pair of holes 0, substantially as set forth.
4. In asash-holder, the combination of the casing having a curved slot, 1), the spring-actuated carrier provided with rollers, and the lever-lock having a curved head, I, and handle J, and a stem, j, connected with said han dle and projecting through the slot B, substantially as set forth.
5. 'Iheimproved sash-holder consisting of the casing having curved slot B and parallel slots a, and provided with a series of holes, 0, the carrier having bearing-rollers and provided with lateral studs projected into slots a, the lever-lock having a head, I, curved at 'i eccentrically to its pivot, and provided with a bandle, J, the stem j, extended from said handle through slot B, the stop-plate L, and the sup port N therefor, all arranged and operating substantially as set forth.
