. SPECIFICATION forming part of Letters Patent No. 633,924, dated September 26, 1899.

' Application iiled June 29,1896. Serial No. 597,437. (No model.)

Be it known that I, HORATIO R. SWART- WOOD, a citizen of the vUnited States, residing at Tracy, in the county of Lyon and State of Minnesota, have invented certain new and useful Improvements in VVindoW-Sash Holders and I do hereby declare the following to vention, such as will enable others skilled in the art to which it appertains to make and use up-and-doivn movement of the sash can be the same.

My invention relates to sash-fasteners. j My object is to provide an improved sashfastener which will be adapted to hold the sash in raised position in a highly-superior manner and yet allow quicker and easier manipulation of the latter.

Having this object in View, the inventionl casing or lhousing, and Fig. 5 is a vertical section taken through the casing andrack.

A designates the ordinary window-sash frame, and B the window-casing. n

The numeral 1 designates a rack `which is preferably constructed of a ribbon of metal crimped into proper shape, and this rack is sunk in the face of the Window-sash and is held in place by fastening devices 2.

The numeral' 3 is a rectangular housing or casing having an inner face-plate 4c. The body 3 of the casing is sunk in the Window-casing, with the face-plate lying adjacent to the rack heretofore designated, screws 5 being ernployed to hold the casing in position. The face-plate and casing are provided With a vertical elongated slot which is in communication With another cylindrical opening 7, that leads to the outer face of said casing. In

the upper portion of the vertical slot :is a pinion 8, which is suitably journaledin the casing or housing y3 in such manner that its teeth kger 10 loosely passes.

had. `Aswill now appear, however, I employ improved means which is adapted to normally keep this spring in engagement with the pinion, so that the latter is locked.

There is a plunger l0, which lies iu open-l ing 7 and has its inner end bifurcated, as

"shown at 1l, the release-spring lying in this bifurcation. One portion of the bifurcated end is formed into an inclined cam 11, which engages with thefreeend of the release-spring and holds the same in engagement with the pinion. The plunger is also provided with a `transversely-eXteriding limit-pin 12.

I employ two screw-threaded bolts 1li-and 14, which are secured for about half their length Withincasing 3 in such manner that lthe other half projects through the outer face of said casing in the manner shown, adjusting-nuts l5 and 16 being provided. There is au adjusting-bar 17, which is free' to slide on the outer ends oi' the bolts between'the casing and the ends and through which the plun- A coil-spring 18 en circles plunger lO and is interposed between adjusting-bar 17 and limit-pin 12, whereby said plunger is normally forced inward and `against release-spring 9, Vforcing theflatter into engagement with the pinion and holding said spring locked. ,By turning the nuts 15 and 16 one way or the other the adjustingbar may be moved forward and the spring compressed, or it may be allowed to move outward, thereby decreasing the tensionof said spring.

The-operation is as follows: Let it be assumed that the window-sash is down and it is desired to raise the same and hold it at any desired height. The plunger rod is first pulled outward `against the action of the coilspring, thereby allowing the free end of the release-spring to spring out of engagement IOO- with the pinion. The window may now bc raised, as the pinion is now free to rotate and mesh with the rack on the window-sash as the latter is 'moved upward, the plunger being meanwhile held retracted by the operator. As soon as the desired height has been reached the plunger should be released,where upon the coil-spring will force said plunger back, thereby causing the earn 1]. to Contact with the release-spring and push the free end of the latter into engagement With the pinion. It will be observed that the plunger locks the release-spring and pinion together, asit were7 and thus prevents the window-sash from descending. When it is desired to lower the sash or raise it still higher, the operation may be repeated. t

My invention is adapted for use in connection with any style of window sash and fraine and may be readily applied thereto Without material defacement; but it is peculiarly adapted for use in connection with railwaycar Windows which may be easily inanipulated, thereby obviating the annoyance heretofore experienced in the use of such windows. Y

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

l. In a sash-fastener, the combination with a window-sash and a rack located thereon, of a rotatable pinion, a fiat releasing-spring having one end fixed and one end free, and a springfpresscd plunger having a bifurcatcd ond straddling the releasing spring, said plunger being adapted to hold vthe free end of the releasing-spring normally in locked engagement with the pinion and said plunger being adapted for retraction to allow the releasing-spring to throw itself out of engageinent withy the pinion.

2. In a sash-fastener, the combination with a Window-sash and a'racl; located thereon, of a rotatable pinion, a flat releasing-spring having one end fixed and the other end free, a plunger having a bifurcated end straddling the releasing-spring, an adjusting-bar loose on said plunger, a coil-spring encircling the plunger and interposed between the adjusting-bar and the bifurcated end thereof, and inechanisinfor adjusting the adjusting-bar, said elements being so disposed and related that the plunger' normally keeps the free end of the releasing-spring in locked engagement with the pinion,and said plunger being adapted for retraction to allow the releasing-spring tothrow itself out of engagement with the pinion.

In testimony whereof I have signed this specilicationin the presence of two subscribing witnesses.

HORATIO R. SlVARTWOOD.
