EDWARD KRAYN, OF NEW' YORK, N. Y., ASSIGNOR TO THE 0. M. EDWARDS GOM- PANY INCL, OF SYRACUSE, NEVI YORK, A CORPORATION OF NEW YORK.

SASH STARTER AND HOLDER.

Application filed February 11, 1924. Serial No. 691,968.

The sliding window-sashes particularly of railway coaches are of necessity close fitting so that they will effectively exclude dust and gases. In consequence slight warping of the parts causes such windows to stick so that the sashes are moved with difficulty, especially from a closed position when the lower cross bar of the sash is in engagement with the sill.

The object of this invention is to provide a device by which mechanical advantage can be brought to bear in slidin the sash, and particularly in starting it Irom its closed position.

Tn'the accompanying sheet of drawings which forms a part of this specification,

Figure 1 shows a portion of a windowsash together with a sash-starter and holder constructed in accordance with this invention, the cover being removed, and the window-frame being shown in section, and

Fig. 2 shows the same with the parts oper ated to start the sash.

This invention comprises a sash starter and holder carried by a window sash which is movable along a window frame, the sash starter and holder, comprising a locking member for coacting with the window frame, and a sash starting member also coacting with the frame, these two members being movable in a direction in a rightangle to each other, and an operating member or lever common to both of said members whereby both are operated upon the single operation of the operating lever, although not necessarily simultaneously operated. The sash starter member preferably pushes against the sill or the frame. This starter and holder is preferably a unitary structure, which can be applied as a unit to the sash, and includes a casing or housing having a stationary pinch handle and the operating lever is arranged opposite to or in juxtaposition to the pinch handle to be within the grasp of the hand taking hold of the stationary pinch handle, as in the conventional sash look.

A vertically sliding window-sash is guided on each side by the side rail 11 of a window-frame, and when closed engages a ledge on the sill 12 of the'window-frame.

engagement by the hand is two and one-half times the distance from the pivot point of the angle lever to the point where it engages the sash-starting member, and the distances from the two pivots to the point of engagement between them being equal, it follows that relative movement to the sash of the point on the hand lever where force is applied and of the sash-starting member is two and one-half to one, but since the sash rises and carries upward the lever. to which upward force is applied, it follows that the total mechanical advantage is three and one-half times. However, these precise proportions are not essential.

The angle lever also carries a sash-holder 17 which is adapted to engage holes 18, 18 in the side rail and hold the sash at various heights, and the sash-holder is retracted concurrently with the operation of the sashstarting member, the same handle serving for the operation of both.

The parts will return after operation by gravity but preferably a spring 19 is provided to insure the return and to prevent rattling. The mechanism is covered by a plate 20.

I claim,

1. The combination with a window frame and a window sash, of a sash starter and holder carried by the sash and comprising a lock member coacting with the frame, a starting member movable in a direction at an angle to the lock member and coacting with the sill of the frame, the lock member being connected to the starting member to actuate it and a pivoted operating member connected to the lock member to operate it.

2. The combination with a Window frame and a Window sash of a sash starter and holder carried by the sash and comprising a movable lock member coacting With the frame, a starting element movable in a direction at an angle to the lock member coacting With the sill of the frame, a pivoted operating member coacting with the lock member and one of said members also coacting With the starting element to actuate it.

EDWARD E. KRAYN.
