COMBINED SASH HOLDER AND SASH RELEASE.

Application filed April 28, 1925. Serial No. 26,365.

To all whom it may concern:

Be it known that we, JoHN L. MOI-IUN and HENRY PIE'sCH, both citizens of the United States, residing at the city of Omaha, county of Douglas, and State of Nebraska, have invented certain new and useful Improvements in Combined Sash Holders and Sash Releases; and We do declare the following to be a full, clear, and exact description of the in vention, such as will enable others skilled in the art to which it appertains to make and use the same.

Our invention relates to sash holders such as are commonly used on railroad car windows, but more particularly has reference to that class of such devices in which the operation of the lever to elevate the sash also causes a force to be exerted for the purpose of releasing the sash when it is closed and stuck at the sill on sides.

The object of this invention is to release the sash not only when it is stuck to the sill or to the sides when the sash is closed, but also when the sash is stuck at the sides with the window open, and to accomplish this without the projection of any part through the bottom of the sash, thereby rendering. it unnecessary to provide striker plates in the sill. r

A further object of the invention is to lock the sash when closed. 1

A still further object is to effect the release of the sash when it is open and has become stuck to theside frame at any point.

In the accompanying drawings which form a part of this application Figure 1 is a broken and partly sectioned elevation showing our improvement installed on a window sash with a locking engagement effected with the metal rack at the side of the window frame. I

' Figure 2 is a similar view showing the position of parts when the lever'has been partially raised to effect the release of the sash from the sill.

Figure 3 is a similar view showing th posit-ion of parts when the lever has been fully raised to withdraw the locking member from the rack at the-side of the frame and to elevate the sash to a desiredlocation.

Figure 4 is a similar view showing the position of parts after the lever has been released from the position shown at Figure 3.

Figure 5 is a detail perspective view of the cam lever.

Figure 6 is a detail perspective of the lock and release member.

H Figure 7 is a section at the line 77 of Figure 4.

Figure 8 is a view similar to Figure 7 but showing modified forms of the bosses and dowels, and

Figure 9 is a view similar to Figure 1 but broken away at the upper portion, and showing a modified form of spring for throwing the looking member into engagement with the rack at the side of the frame.

Similar numerals of reference denote like parts in the several figures of the drawing. Heretofore sash holders have been equipped with means whereby, when the lever was raised, a pressure would be brought to bear directly against the window sill, thus necessitating metal striker plates mortised within the sill, and also requiring that the bottom of the sash should be cut away to accommodate said means.

Also, devices of the above nature released a sash only when it was closed and stuck at the sides or at the bottom against the sill, butno provision has heretofore been made for releasing the sash when it was part way open and stuck at the side or sides of the window frame. I

Moreover, in many instances, car windows,

as ordinarily constructed and equipped with sash holders, are readily opened by inserting a tool to throw back the locking member, and, as a car frequently contains valuable matter, its contents are unsafe. But with the use of our improvement said member is actually a locking member, and it is impossible to disengage it surreptitiously from the rack at the side of the frame unless the wlndow is elevated.

Referring to thedrawings 1 is the sash, 2

8 is the operating lever which extends laterally through the usual elongated slot (not shown) at the inside edge of the easing so as to be capable of free play within said slot, and 9 is the usual rigid arm extending integrally from the inside of the casing and against which the manipulator of the holder usually rests his thumb when raising the: lever 8 with his fingers.

The lever 8 is enlarged at its inner end and formed into a cam 10, and this enlarged portion is pierced at 11 and placed around the post 6 so as to form a pivot for the lever with the cam at the bottom, and a lug 12 extends laterally from the outer extremity of the cam. 13 is a screw driven in the post and having a broad head 14 which serves to retain all parts that are around the post and also functions to sustain any side thrust of the pivoted portion of the lever.

15 is a combined lock and window release dog which has an elongated slot 16 at a suitable location midway of its ends, which dog is pivoted around the post 6 alongside the cam 10 by reason of the fact that the post 6 extends through said slot.

This dog has an offset 17 immediately below the slot the upper face of which offset is curved and is in the same vertical plane with the cam 10 and is always in contact therewith, so that when the lever 8 is raised the cam will operate against this offset and exert a force to drive the dog 15 downwardly, and when the lever has been raised sufficiently the lug 12 will strike the dog and throw the latter away from the rack 3 as will be presently more in detail set forth. The nose of the dog 15 is formed into a rack engaging pawl 18, and the other or upper end of the dog terminates in a tail 19, which is normally in abutment with a stop shoulder 20 at the top of the casing 5, whereby, when the sash is closed and both the nose and tail of the dog are engaged in the manner above set forth, the sash will be locked since it will be impossible to throw said nose out of engagement with the rack.

21 are dowel pins threaded at each end and driven within the bosses 7, each pin having a taperedshouldered portion 22 which abuts the boss, the outer ends of the pins extending through perforations in the sash slightly beyond the latter, nuts 23 being driven on the ends of these pins thereby drawing the tapered portions snugly within the sash and fastening the casing 5 firmly to the sash.

In this connection it would be well to say that, while we prefer to use dowels like the pins above described, dowels of any sort affixed to or integral with the casing may be used, or, as shown at Figure 8, machine screws 25 having square heads 26 may be driven into the bosses 7, said heads impinging on a plate 27 outside the sash and secured as against turning by lips 29 turned up from the plate against the heads.

In Figures 1, 2, 3, and 4, we have shown a coil spring 24 fixed at its extremities to the casing and the dog 15, to always exert a pressure against the latter to force it into engagement with the rack. But a flat spring may be utilized in this connection and at Figure 9 we have shown such a spring 28 which is secured to the casing and bears against the dog. Therefore, it will be clear that our invention is not limited in this re spect, and that we can employ any suitable spring means whereby the dog is always urged into engagement with the rack.

The operation of our improvement is as follows Presupposing the window to be fully lowered with the parts in the positions shown at Figure 1, the operator grasps the lever 8 and raises it, thereby forcing the cam 10 against the offset 17 and this will cause the nose of the dog to impinge with great force against the rack and thus break any sticking contact of the sash with either the sill or the side frames of the window, and the sash will rise slightly carrying with it the entire casing 5, and all the parts therein except the dog until the post 6 is at the upper end of the slot 12, and the parts will be in the position shown at Figure 2.

The final raising of the lever 8 will cause 1 the lug 12 to force the dog 15 out of the rack since the tail 19 is now clear of the shoulder 20 and the sash is then raised to a desired elevation, and the position of the parts at this time will be as is shown at Figure 3. The lever 8 is then released, thus causing the spring to throw the dog into engagement with the rack, whereupon the parts will return to normal position as shownv at Figure 4. I

With the sash open, it frequently happens that the sash becomes stuck at the sides to the window frame, but since the dog acts against the rack it is immaterial whether it impinges against the bottom of the rack or against parts of the latter above the bottom, and therefore our invention is effective under all conditions of this sort.

There are two of these fixtures and racks one a each side of the sash and frame respectively, but as they are exact duplicates the description and claims herein specify them in the singular number.

Whenever the lever is released, it will be restored to its normal position, shown at Figures 1 and 4, by the resilient action of the spring that acts on the dog, owing to the fact that the dog will throw the lug upward while the offset 17 that is always in contact with the cam 10 will also act against the latter to throw this lever into its normal position, and in this connection attention is called to the fact that this lever is therefore always under spring tension, so that there can be no rattling thereof.

While we have illustrated and described our invention in connection with window sashes such as are used in railroad cars, it will, of course, be understood that the inven tion may be utilized in the instance of any sort of a wind-ow sash such as is used in street cars, busses and houses, and, therefore, this invention is, of course, not limited in this respect.

\Vhat is claimed is 1. A sash slidable in a window frame to the side of which latter is fixed a metal rack, a metal casing carried by the sash in proximity to said rack, a spring impelled lockingdog slidably pivoted in said casing and normally engaging said rack, and a lever extending from the casing and hav ing its inner end pivoted therein and formed into a cam which contacts said dog and provided with a lug which extends laterally above said dog, whereby, when said lever is raised, the dog will be driven clownwardly against the rack and subsequently forced therefrom by said lug.

2. A sash holder and window release, comprising a casing secured to the sash, rack in the window frame, a dog pivotally supported in said casing and capable of limited vertical play, an operating; lever whose inner end is formed into a cam and has a laterally extendinglug, and a spring normally urging said dog into engagement with said rack, whereby the elevation of said lever will force the cam against the dog and cause the latter to be impelled downwardly against the rack.

3. In a sash holder and window release, a window frame having a side rack, a sash slidable in said frame, a casing secured to the sash in proximity to said rack, a lever extended from the casing and having its inner end pivoted in the casing and formed into a cam with a laterally extending lug, a dog slidably pivoted in the casing in the vertical plane of said lug and having a part normally in contact with said cam, and spring means urging the bottom of the dog into engagement with said rack.

4. A combined sash holder and window release, comprising a rack in the side of the window frame, a casing carried by the sash in proximity to the rack, a dog pivoted in the casing, a lever also pivoted in the casing, a spring which causes said dog to normally engage said rack, and cooperating means carried by said lever and dog whereby the elevation of the lever will drive the dog downwardly against the rack to raise the sash and subsequently force the dog out of engagement with the rack against the resiliency of said spring.

5. A construction as in claim 1, in which the dog and lever are pivoted in juxtaposition around a post in the casing, the dog having a tail portion adapted to lie behind a shoulder of the casing when the nose of the dog is engaged with the rack.

6. A construction as in claim 1, in which a post in the casing extends through a perforation in the cam and through a vertical.- ly disposed elongated slot in the dog, the latter having an offset surface in contact with said cam.

7. A construction as in claim 1 in which the cam and the dog have the same pivot and are juxtaposed, the dog having an olfset portion which is immediately beneath the cam and in contact therewith, while the cam terminates in an offset lug which is in the same vertical plane with the dog.

In testimony whereof we affix our signatures hereto.
