WINDOW-SASH REGULATOR AND OPERATOR.

Specification of Letters Patent.

Patented Aug. 23, 1921.

Application filed September 22, 1919. Serial No. 325,394.

To all whom it may concern:

Be it known that I, LoUIs J. GOUIN, a citizen of the United States, residing at Freeport, in the county of Stephenson and State of Illinois, have invented new and useful Improvements in Window-Sash Regulators and Operators, of which the following is a specification.

The object of the invention is to provide a relatively simple and inexpensive mechanism by means of which a window sash, such for example as those employed in con nection with railways, street and other cars and vehicles of a like character may be readily raised and lowered, or opened and closed, and held at any desired intermediate position against displacement or rattling, and whereby when raised or closed the sill strip will be secured and locked in a position to exclude rain from the recess or housing in which the sash is received when lowered or opened.

With these and related objects in view, the invention consists in a construction,

combination and relation of parts of which a preferred embodiment is illustrated in the accompanying drawings, it being understood that changes in form, proportions and details may be resorted to within the scope of the appended claims, without departing from the principles involved.

In the drawings:

Figure 1 is a front or inner side view, of the apparatus, a portion of the sill of the car being broken away to expose the same.

Fig. 2 is a vertical sectional view of the same.

Figs. 3, 4 and 5 are transverse sectional views on the planes indicated respectively by the dotted lines 3-3, 4-4 and 55 of Fig. 2.

Fig. 6 is a detail view of the traveler which traverses the feed screw to communicate raising and lowering movement to the sash.

Mounted at its upper and lower ends in a frame having the base and top bars 10 and 11 connected by the uprights 12, the former being suitably secured to a sill 13 by means of screws 14 or the equivalent thereof, is an upright feed screw 15 of which the reduced lower end is mounted in a bearing 16 in the base bar while the upper end is mounted in a bearing 17 formed in a yoke 18 rising from said upper bar 11. Said feed screw may be rotated in opposite directions as for example by means consisting of a pinion 19 secured thereto as by a pin 20 near its upper end and engaged by a gear 21 to the sleeve hub 22 to which is attached an operating crank 23. Said sleeve hub preferably progects through an opening formed in a metallic face plate 24 and is mounted upon a stub shaft 25 consisting of a bolt extending outward from the upper cross bar 11 and provlded at its outer end with a threaded bore for engagement by a cap screw 26 which serves to hold the eye 27 of the crank arm in place upon the sleeve hub of the operating gear.

Mounted for operation in suitable guides in the frame work of the vehicle is the sash of which the preferably metallic frame is indicated at 28 for the reception of the edges of the glass 29, and connected with said frame by means of an angular bracket 30 is a traveler 31 of which the bifurcated extremity 32 is adapted to engage the threads of the feed screw, so that upon rotation of the latter in opposite directions motion in corresponding directions is communicated to the sash. Obviously the sash may be held either in. its lowered or raised position or in any intermediate position merely by discontinuing the operation of the feed screw, but in order to frictionally lock the operating means against accidental movement, a friction stop is provided to consist of a projection 33 on the upper cross bar 11 to engage a socket or depression 34 in the operating gear. Or obviously, the relation of these interlocking elements may be reversed.

The sill strip 35 which Is adapted to close the guide for the sash when the latter is in its lowered position, is adapted to be elevated to the position indicated in Fig. 2, by the movement of the sash and the frame of the latter is provided-with a returned weather strip 36 for engagement with a complementary weather strip 37 secured to the sill strips, said strips being adapted to interlock when the sash reaches the limit of its upward movement, so as to provide a brace joint to exclude moisture and rain from the space in the wall of the car or vehicle provided for the reception of the sash and constituting a housing for the same.

From the foregoing description it is obvious that the apparatus may be readil at tached to the vehicle, the various parts t we of being so related as to be mutually supporting independently, practically, v of the vehicle itself, and the adjustment of the sash may be effected merely by the operation of the crank arm which is within convenient reach of the occupant of the car or vehicle, the extent of opening of the window bein dependent directly upon the operation 0 the crank arm, and the parts being so related that the sash is secured against accidental movement by the relation between the traveler and the feed screw.

As hereinabove described the traveler 31 is pivotallly mounted upon the sash frame, and in or er that it may readil be disconnected or disengaged from the t read of the feed screw it is obvious that it must be capable of flexure or in other words that it must be yieldable to permit of backin or swin ing the free end thereof away rom the eed screw, and the advantage of this disengagement is that the use of the device as a means of raising and lowerin the sash may be discontinued when desire the sash being free for operation manually in the ordinar way. A further advantage of the detacha ility or possibility of disengaging the traveler from the feed screw is that it materially aids the assembling of the parts when the are applied to the car or other vehicle. oreover the engagement of the traveler may be varied with reference to the threads of the feed screw to insure the location of the crank arm 23 in the desired position, as for example in a pendant position, when the sash is at the limit of its upward or closing adjustment, so that said handle will offer no obstruction in the window opening.

A further advantage in the specified construction and mounting of the traveler resides in the fact that it may be replaced when worn by a new traveler without involving any substantial change.

Having thus described my invention what I claim as new is 1. A'sash operating mechanism havin a feed screw arranged substantially ara lel with. the path of the sash, a bendab e traveler connected with the sash, and engaged with said feed screw, and means for imparting rotary movement to the screw, the traveler being disengageable from the screw by lateral movement.

2. A sash operating mechanism having a feed screw and means for communicating rotary motion thereto, a sash having a metallic frame, and a traveler pivotally at tached to said frame and havlng a bifurcated extremity engaged upon the screw, the traveler being dlsengageable by lateral movement thereof.

3. A sash operating mechanism having a frame for arrangement between the outer shell and the lining of a vehicle wall and consisting of spaced base and top cross bars and connecting side bars, the top cross bar being provided with an arched extension, a feed screw revolubly mounted in bearings in the base bar and the arch of said top cross bar and carrying a pinion, an operating ear mounted upon a spindle supported by t e top cross bar of said frame in mesh with said pinion and having an operating crank arm located inside the plane of the lining of the vehicle wall, and a traveler connected with the sash and having detachable engagement with the thread of said feed screw.

In testimony whereof I aflix my signature.

LOUIS J. GOUIN.
