A CORPORATION OF NEW YORK SASH HOLDER/WITH ANTIRATTLER MEANS Application filed'May 29,

This invention relates to sash holdersor sash locks for windows, particularly vehicle or railway car windows where the sashes are subject to continuous vibration when the vehicle is in motion, and has for its object, a particularly simple, economical and efiicicnt means for holding theoperating members or levers, or other parts from rattling, particularly when the vehicle is in motion,

The invention consists in the novel fea tu'res and in the combinations and constructions hereinafter set forth and claimed,

In describing this invention, reference is had to the accompanying drawings in which like characters parts in all the views. p

This sash holder comprises generally, a body element for attachmentto an element of the sash, as the bottom rail of the sash, a latch,

member or bolt, an operating member or lever 1 :5 movably mounted in the body, connections between the lever and the latch or bolt, and

vmeans for holding the'operatin'g member or lever from rattling. It also usually in-. cludes a sash starter member for prying the 0 sash away from the sill, this being a plunger designate corresponding is securedto the bottom rail of the sash in V a flat spring extending lengthwise of the arm 1930.

holder, this being formed with a recess 2 open at one side, which recess is closed by the wall of the sash element, that is, the wall of the bottom rail of the. sash when the body is attached to the sash.

3 designates an operating member which is an angle lever pivoted at:3 'at its angle, one arm of which constitutes ajfinger piece, and the other arm of which extends into the 7'? recess 2, and has a pin 4 at its free end which is connected to the latch or bolt 5.

In the form shown in Figures 1 and 2, the latch or bolt is located within a suitable guide in the hollow bottom rail 6 of the sash and projects beyond the edge of the sash and coacts with openings or depressions as 7 in the sash guide& This bolt 5 is spring pressed outwardly, and is retracted against the action of its spring by the depression of the operating lever 3. The pin 4. of the operating lever extends through a slot 9 in the wall of the bottom rail 6 and enters an opening in a stem 5 on the latch or bolt 5. The body 1 7 any suitable manner, as by screws 10. Also, a. plate 11 is mounted on the bottom rail by screws 12, this having a flangelS arranged in pinch handle relation to the finger piece of the leveri3. I i

The construction thus far described, forms no part of this invention, and this invention relates primarily to the anti-rattling means.

The anti-rattling means comprises a spring 14 thrusting againstthe lever 3 and against the opposing wall of therecess 2. In this instance, the opposing'wall is the portion of the bottom rail which closes the open side of the recess 2. The spring is preferably of the lever in the recess 2 and it is fixed at one end to said arm, and has its other arm free and pressed against the portion of the bottom rail of the sash which closes the recess 2.

Preferably, one end of the spring is fixed substantially at or concentric with the pin a, or the point where the lever is connected to the latch member, or the part which transmits motion to the latch member, and the free end of the spring is locatedsubstantially at the pivot of the lever, and in order to reduce friction, it is provided with a boss or bearing 15 at the pivot point. The spring.

thus ex ends radially of the arm within the recess 2 and is arranged fiatwise thereon.

16 designates a starting plunger movable vertically in a guide 17 formed in'the body, the plunger having a head 18 arranged to be engaged by the lever 3 when it is depressed in order to thrust the plunger downwardly against the sill to start the sash away from the sill when the latch or bolt 5 is being with drawn.

In order to hold the plunger from rattling, spring means is provided between the plunger and the wall of this'guide, this being here shown as a flat spring 20 extending lengthwise of the plunger and fix at one end thereto and having its other end free so as to press against the wall of the guide.

The spring is here shown as located in a groove 21 in the plunger with one end 22 projecting out of the groove in order to engage "the wall of the guide, and the other end lying in the groove. The latter end is fixed in the groove by contracting or upsetting spaced portions 23 of the walls of the groove on the end of the spring seated in tne groove. Obviously, the spring 20 will hold the plunger from rattling.

In Figures 6, 7 and 8, another form of sash holder or lock is shown comprising a body 2% having a recess 25 therein, which when the body is applied to the sash, is closed by the bottom rail 26 of the sash.

27 is an angular operating lever for withdrawing the latch member or bolt 28, this lever being pivoted at its end at 29 instead of at its angle, and being connected at its angle to the latch or lock member by a pin 30 working in a slot 31 in the latch or bolt member. The latch or bolt member is guided in thebody instead of in the bottom rail of the sash as in Figure 1, and hence, the sash holder mechanism is self contained.

In this embodiment of my invention, the spring 32 is fixed to the arm of the lever in the recess 25 of the body 24 by the pin or rivet 33, and its free end is located near or concentric with the pivot 29, and presses against the portion of the bottom rail which closes the recess 25.

Owing to the location of the spring in both embodiments so that its free end is concentric with the pivot point of the lever, there is minimum friction between the spring and the surface against which it bears during operation of the lever.

This anti-rattling means is particularly advantageous in that it is readily applied to present sash holders or looks, and requires minimum space, and further in that it absolutely prevents rattling of the parts which have heretofore been a great source of annoyance to passengers.

What I claim is:

1. A sash holder comprising a body element for attachment to an element of a window sash, a latch member, an operating member movably mounted in the body, and a flat spring fixed to the operating member at one end and thrusting at its other end against one of said elements in a direction at an angle to the operating movement of the operating member.

2. A sash holder comprising a body element for attachment to an element of the window sash, an operating lever pivoted to the body element, connections between said lever and the latch member to operate the latter, and a flat spring extending lengthwise of one of the arms of the lever radially relatively to the pivot thereof and being fixed at one end to said arm and having its other i.

end thrusting against the contiguous wall of one of said elements.

3. A sash holder comprising a body element for attachment to an element of the window sash, a latch member, an operating lever pivoted to the body element, connections between the lever and the latch member to operate the latter, and a flat spring fixed to one of the arms of the lever at a point remote from the pivot of the lever, and having its other end free and located at the pivot of the lever and thrusting against the opposing wall of one of said elements for holding the lever from rattling.

4. A sash holder for windows comprising a body having a recess open at one side for attachment to a window sash with the open side of the recess closed by the sash, a latch element, an operating member movably mounted in the body and connected to the latch element to operate the same, and a spring interposed between the sash and the operating member for thrusting the operating member in a direction at an angle to its operating movement and thereby holding the operating member from rattling. V

5. In a sash holder for windows comprising a body for attachment to the window sash, a movable operating member movably mounted in the body, the body being formed with a guide and a sash starting plunger mounted in the guide and arranged to be actuated by the operating member, and means for thrusting the plunger laterally relatively to its operating movement and thereby preventing the rattling of the plunger. I

6. In a sash holder for windows comprising a body for attachment to the window sash, a movable operating member movably mounted in the body, the body being formed with a guide and a sash starting plunger mounted in the guide and arranged tobe actuated by the operating member, the plungor being formed with a lengthwise slot, a leaf spring in the slot and having one end projecting out of the slot and arranged to thrust against the wall of the guide, the other end of the spring being located in the slot and the Walls of the slot being contracted over the latter end of the spring to fix the same in the slot.

7 The combination of a guide, a member slidable in the guide, said member being formed with a lengthwise recess, and a spring having one end portion lying in the recess and its other end extending out of the recess to engage the guide, the walls of the recess being upset to overlie the portion of the sprin in the recess.

8. K sash holder comprising a body for attachment to a window sash, a movable latch member, an operating member movable in the body-and coacting with the latch member and spring means for thrusting the latch member laterally relatively to its operating movement for holding the operating member from rattling.
