To all whom, it may concern.-

Be it known that I, \VALTER Fnosr, a subject of the Queen of Great Britain, residing at London, England, haveinvented new and useful Improvements in Apparatus for Raising and Lowering the \Vindows of Railway and other Carriages, of which the following is a specification.

This invention relates to improvements in apparatus for raising and lowering the sliding windows of railway and other carriages, the object of the invention being the production of an apparatus whereby the sashes can be easily and quickly opened and closed by merely operating by the hand a handle or knob on the inside of the carriage door or window.

In carrying outmy invention the sash-frame carrying the glass is made to freely run up and down in grooves or guides, as usual, and the said sash frame is counterbalanced by a spring or weight. Along the bottom of the sash-frame is a slot, in which runs a small wheel or runnerblock. The said wheel or runner-b1ock is attached to the end of a radiating lever, jointed at the other end to the side of the sash-box, and at a short distance from this joint there is jointed on the radiating lever a link, which is connected at the other end to a crank fixed rigidly on the spindle of the knob or handle in such a manner that when the handle or knob having the crank is turned it communicates a motion to the radiating lever by means of the link, and by means of the radiating lever a raising or lowering motion is given to the sash-frame, according to the direction in which the handle is turned.

I sometimes employ in connection with the said apparatus a ratchet arrangement consisting of two ratchet-wheels attached to the spindle of the handle, the said ratchetwheels having their teeth formed in opposite directions. The crank on the handle works frictionwise with one of the ratchet-wheels, which allows of the window being lowered by the pressure of the hand without using the handle. The other wheel is rigidly fixed to the handlespindle, and in the teeth of the said ratchetwheels works a compound-spring ratchet. The main part of the ratchet takes into the wheel which works frictionwise with the crank, and the other part of the ratchet takes into the ratchet-Wheel fixed rigidly on the spindle of the handle. These ratchets operate in such a manner that when the handle is turned to the right hand the ratchet-wheels revolve and allow the main ratchet to fall successively into the teeth of its ratchet-wheel until the sash-frame is raised to its desired position, when the handle will be prevented from turning any farther. By turning the handle to the left hand the ratchet-wheel fixed rigidly on the handle-spindle is first moved the distance of the length of a tooth in the wheels, the ratchetwheel fixed on the handle-spindle having a pin which works in a slot in the ratchet-wheel which is loose on the handlespindle, which arrangement allows of the said motion, and by this motion the main ratchet is raised out of its ratchet-wheel by the second part of the ratchet acting on apin in the main ratchet, thus allowing the sash-frame. to be lowered tooth by tooth until the turning of the handle stops, and by this arrangement the window can be maintained at any required position or height.

In order to enable my invention to be fully understood, I will proceed to describe the same by reference to the accompanying drawings, in which- Figure 1 represents an elevation of the outer side of a railway or other carriage door, showing my improved apparatus for raising and lowering the window of the same applied thereto. In this view part of the frame of the door is removed to more clearly illustrate my invention, and the window is shown in its raised or closed position. Fig. 2 is a vertical transverse section of the same on line A B of Fig. 1. Fig. 3 is a similar view to Fig. 1, but showing the window in its lowered or open position. Figs. 4, 5, and 6 are similar views to Figs. 1, 2, and 3, but showing the improved apparatus provided with an arrangement of ratchetwheels to admit of the window being lowered by the pressure of the hand alone when required. Figs. 7, 8, and 9 are detached views drawn to a larger scale, showing the arrangement of the ratchet wheels.

Similar letters in all the figures represent similar parts.

I will first describe my invention by reference to Figs. 1 to 3.

q is the sash-frame of the window, made to freely run up and down in the grooves or guides b, in the frame of the door 0 (or of the window) in the usual manner.

y is a barrel containing a coil-spring for counterbalancing the weight of the sash frame; or a weight may be employed for this purpose.

e is the slot at the bottom of the sash-frame a, and f is the small wheel, roller, or runnerblock, which runs in the slot e.

g is the radiating lever, to one end of which the roller f is attached, the other end being jointed at h to the side of the sash-box t.

'j is the link, jointed at k to the radiating lever g, and Z is the crank on the spindle m of the knob or handle a, to which crank l the other end of the linkj is jointed, as shown.

2 is a tape or band, of metalorother suitable material, which passes round the barrel yand is attached to the radiating lever y, and which is wound on the said barrel by means of the coil-spring hereinbefore described, so as to assist in raising the window.

To raise the window, the parts being in the position shown in Fig. 9, the handle it is turned toward the right-hand side, whereby the crank Z will raise the link j and radiating lever 9, thereby raising the sash frame a, which will remain in any position to which it may be raised or lowered by being counterweighted by the coil-spring, which operates the barrel 3 and winds the tape or band z thereon and assists in raising the radiating lever g. To lower the window, the handle nis simply turned'in the opposite direction, and the operation of the parts will be well understood without further description. If required, the crank 1 may have notches or teeth out in its circular portion and a spring locking-piece taking into these teeth in such a manner that it can be unlocked on turning the handle in either direction.

In the arrangement shown in Figs. 4 to 9, in which the ratchet arrangement is employed, a spiral spring, d, is shown for counterbalancing the weight of the window, the said spring being attached to the door-frame c and to the link j.

0 and p are the two ratchet-wheels, having their teeth formed in opposite directions, as shown clearly in elevation at Figs. 7 and 8, and in section at Fig. 9. The ratchet-wheel o is loose upon the handle-spindle m, and works frictionwise with the crank Z by means of a spring-plate, g, riveted or otherwise suitably fixed to the ratchet-wheel 0, and bearing upon the surface of the boss 1' of the crank, as shown in Fig. 9. The ratchet-wheel ois provided with a boss, s, upon which the boss 1 of the crank can rotate when thewindow is lowered by the pressure of the hand without using the handle n. When, however, the

window is raised or lowered by means of the.

handle at, the boss of the crank is by means of the said friction forced to rotate with the ratchet-wheel 0, as hereinafter described. The" other ratchet-wheel, p, is rigidly fixed to the handle-spindle 1n.

t' and u represent the compound -spring ratchet. the ratchet-wheel 0, and the other part,u,piv oted to the main part t, takes into the matchet-wheel p.

The main part, t, thereof takes into v is the pin on the ratchet-wheel p, and w: is the slot in the ratchet-wheel o, in which 'slot the pin 1) works, and by means of which To raise the window, the"parts being in the position shown in Fig. 6, thehandlen is turned toward the right hand in the direction indicated by the arrow in Fig. 7, when the mainratchet t, as the ratchet-wheels o and p revolve, will fall successively into the teeth of its ratchet-wheel 0, and the part a of the compound ratchet will pivot on the main ratchet t, and will pass over the teeth of its ratchet p. The ratchet-wheels as they revolve will carry with them the crank Z, which, by means of the link j, will cause the radiatinglever gto raise the window, the rollerf meanwhile sliding in:

its slot e until the window is closed, when the handle will be prevented from turning any farther, or until the window is raised to any other required position or height, at which position or height it will be maintained. To lower the window, the handle 1:. is turned to? ward the left-hand side in the direction indicated by the arrow in Fig. 8, when the main.

ratchet will be moved out of the teeth of its ratchet-wheel 0 in the manner hereinbefore described, and shown in the said Fig. 8, and

both ratchet-wheels will be free to rotate, andwill carry with them the crank 1' until the window has been lowered to the required potion by means of the link j and lever g, whenthe handle n is released and thewindow will be maintained in the said position.

If the window be pressed by the hand in order to lower the same, the ratchet-wheels will be prevented from moving by means of V the compound ratchet, and the boss r of the crank will be forced by the window operating the link j and lever g to move frictionwise over the ratchet 0.

Having now described the nature of the said invention and in what manner the same is to I be performed, what I claim is- 1. In apparatus for raising and lowering the windows of railway and other carriages, the combination of a radiating leverjointed at one end to the frame of the door or window, and having its other end sliding in a slot in the sash-frame,with a link and crank,substantially as and for the purposes hereinbefore described.

2. In apparatus for raising and lowering the windows of railway and other carriages,-the combination of a radiatingleverjointed at one end to the frame of the door or window, and having its other end sliding in a slot in the sash-frame, with a link, and a crank rigidly fixed on the spindle of a handle working in the frame of the carriage door or window and a counterbalanoing-spring, (or a weight,) all arranged substantially as and for the purposes hereinbefore described,and represented in the accompanying drawings.
