Specification of Letters Patent.

latented May 22, 1906.

Application filed October 23,1905- Serial No. 284,110.

To aZZ whom it may concern:

Be it known that I, EDMUND M. ERB, residing at Jersey City, in the county of I-Iudson and State of New Jersey, have invented certain new and useful Improvements in VVindows, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to window construction, and with regard to the more specific features thereof, to car-windows and devices adapted to be used in conjunction therewith.

One of its objects is to provide eflicient and compactly-disposed means adapted securely to look a sash in any desired position.

Another object is to provide simple and readily-actuated means adapted for use in connection with locking means of the above type for releasing and relocking the same at will.

Another object is to provide means of simple and inexpensive construction and reliable and automatic action adapted. to prevent the fall of a sash upon the balancing or suspending means becoming broken or otherwise deranged.

Other objects will be in part obvious and. in part pointed out hereinafter.

The invention accordingly consists in the features of construction, combinations of elements, and arrangement of parts, which will he exemplified in the devices hereinafter de scribed and the scope of the application of which will be indicated in the following claims.

In the accompanying drawings, wherein is shown one of various possible embodiments of my invention, Figure 1. is an elevation of the same, partially in section, showing the same in operative condition. Fig. 2 is a perspective view of certain portions thereof. Fig. 3 is a sectional view taken 011 the line w 7 'w of Fig. 1, showing the parts on a larger scale. Fig. 4 is a sectional view taken. on the line 90 aof Fig. 1, showing the parts on a slightly larger scale. Fig. 5 is a sectional elevation taken on the line 1 3 of Fig. 1. Fig. 6 is a plan view, partly in section, of certain parts shown in Fig. 2. Fig. 7 is a detail perspective of locking means. Fig. 8 is a sectional elevation of certain parts shown in Fig. 1., the same appearing on a larger scale. Fig. 9 is adetail perspective of a locking member. Fig.10 is a view similar to Fig. 4, taken on the line .2 z of Fig. 1. Fig. 11 is an e11- larged detail sectional view of parts shown in Fig. 5, the same appearing in another position.

Similar reference characters referto similar parts throughout the several views of the drawings.

The description of this illustrative embodiment of my invention will be most clearly understood and its full meaning most readily grasped if the following facts be borne in mind.

In windows in generahand particularly in the case of car-windows, by reason of the almost constant vibration and jarring to which they are subjected there is a tendency for the same if opened to work out of the position in which they are placed unless locking means he provided to prevent such action. It is, moreover, desirable that these locking means be operative in various positions of the sash in order to attain the exact regulation of entering air, which is peculiarly desirable in car-windows. If the locking means employed be of the well-known type in which the more or less precarious engagement of some form of latch is depended upon, the same is often jarred into releasedcondition, whereupon the sash, unless fully balanced, falls, with possible damage thereto and alikelihood of personal injury to the passenger, who is often obliged to sit closely adjacent thereto. It may also be noted that in the case of the failure of the balancing means-due, for eX- ample, to breakage of the parts-it is likely that the sudden jar and increase of weight will throw out the ordinary locking means, or if the same be released, as in the act of raising the window, the sash will be wrenched free and fall, with the above-noted results.

The above and otherdefects are obviated and many positive advantages attained in the invention hereinafter set forth.

Referring now to the drawings, 1 denotes the sash of a car-window mounted for sliding movement within the frame 2, provided with the usual front and back stops 3 and 4, re spectively. Sash 1 is suspended in the frame by means of flexible bands or tapes 5, adapted to be wound upon a spring drum orroller or connected with other devices. (Not shown.) It may be noted, however, that bands 5, but one of which is herein shown,

are connected with a source of power sufficient normally to urge the sash to an upward sliding movement in frame 2 when released by the retaining devices hereinafter to be described.

Sash 1 comprises a frame 6, preferably of metal, the lower part thereof being hollow, so as to receive controlling devices. This lower sash-frame member comprises a channel-bar 7, the flanges of which are secured within the inner and outer plates 8 and 9, which in like manner embrace an upper channel member 10. Both sides of this sash being identical, but one side is herein illustrated in detail, and a description of one side thereof, with the parts associated therewith, will therefore suffice to impart a complete disclosure of the invention.

The lateral sash members 11 are preferably of metallic construction and are formed substantially in channel shape, as best shown in Fig. 10 of the drawings.

Extending from frame 2 and rigidly mounted thereon is a guide 12, provided with an integral fin or flange 13, projecting within channel 11 and arranged in proximity with one of the flanges thereof, so as to guide the sash in its sliding movement, sufiicient space being allowed between member 13 and stop 4 to prevent excessive friction between the sash and the last-mentioned part.

Fixed within channel 11 is in the present instance a bearing 14, journaled within which is an antifriction-roller 15, designed to coact with a wedge or cam 16, extending from the web 17 of a channel-shaped shoe 18, mounted to reciprocate between fin 13 and one of the walls of channel 11.

The face 19 of shoe 18-lies normally in proximity to fin 13, which projects within the channel, as above set forth. Pivotally connected to shoe 18 by means of link 20 is a rod 21, slidably mounted in guide-brackets 22, fixed upon the sash. The lower end of rod 21 rests in a recess 23, formed in the end of a bell-crank lever 24, pivotally mounted, as at 25, upon a bracket extending from a wall or partition 26 within the lower member of sash 1. Coiled about rod 21 between the lowermost of brackets 22 and a shoulder 27 is a spiral spring 28, tending to force rod 21 downward, so that wedge member 16 is normally drawn down against antifriction-roller 15. Partition 26 is recessed to allow free play of bell-crank lever 24, and pivotally connected with the latter member at 29 is a rod 30, extending at right angles to red 21 through guide-plates 31 and 32 and provided with an offset portion 33, pivotally connected with a lever 34, mounted in a bracket 35, formed upon one of the guide-plates 32. The remaining end of lever 34 has pivotally connected therewith a rod 36, corresponding to rod 30, which passing through similar guideplates is connected with the identical mechanism upon the opposite side of the sash. A spring 37 is coiled about rod between a shoulder 38 and guide-plate 31, normally holding bell-crank lever 24 in the position shown in Fig. 8.

A finger or grip lever 39 is pivotally mounted upon a stud 40, extending from the inner wall of the sash 1, and is provided with a bifurcated end 41, within which the bent portion of rod 30 is received. The outer end of finger-lever 39 extends through an opening 42 in the sash beneath a handle-plate 43 thereon.

Extending horizontally through guideplates 31 and 32 is a locking-bolt 44, normally extending toward the edge of the sash and taking under a locking-lug 45, fixed, as upon guide 12, and provided with an inclined upper surface 46. Rod or bolt 44 is held in extended position by means of spring 47, interposed between guide-plate 31 and the shoulder 48. The inner end of bolt 44 is pivotally connectedwith a lever 49, pivotally mounted upon a bracket 50, mounted upon one of the guide-plates 32. The opposite end of lever 49 has pivotally connected therewith a locking-bolt 51, provided with an offset portion 52, said locking-bolt being similar in construction and action to that already described. A finger-lever 53 extends through an opening 54 in the sash 1 and is pivotally mounted upon a stud 55, the inner end being bifurcated to take about the bent portion Oi locking-bolt 51.

Suspending band or tape 5, connected with the sash-raising mechanism, as hereinbefore described, is connected, by means of link 55, to the hooked end 56 of a bell-crank lever 57, pivotally mounted by a stud 58 upon the upper portion of the sash. The opposite end of bell-crank lever 57 is bifurcated, as at 59,

to take about a pin 60, extending transversely of a recess in the upper end of an angle member 61, having formed thereon a shoe 62. The latter member is provided with a pair of obliquely-extending slots 63, through which pass in the present instance screws 64, driven in the sash. A spring 65, coiled about stud 58 and engaging at its ends sash 1 and a pin 66 upon lever 57, tends to swing the latter member against the tension exerted thereon by suspending band or tape 5. Flange 67 of shoe 62 is thus normally held in proximity to but out of engagement with the fin 13.

Having thus described my invention, the operation thereof is substantially as follows: Assuming the sash 1 to be in closed condition, it will be noted that the same is positively locked by reason of the bolts 44 taking under the fixed lugs and that it is thus securely held in closed condition. If it be desired, however, to lift the sash, the finger levers or grips-39 and 53 are merely compressed, this simple movement withdrawing both of the bolts 44 and swinging the bell-crank levers IIO 54 so as to raise the shoes 1.8. The latter movement releases the fin 13 from the pressure to which it has been subjected by reason of the clamping action of the parts between which it is positioned, the disposition of these several members at this stage being best shown in Fig. 11 of the drawings. The sash may then readily be raised to any desired point, or, if the balancing means are of sufficient power, it is automatically lifted. When it has reached the position at which it is desired to relock the same, the grips 39 and 53 are released, thus permitting springs 37 to swing the bell-crank levers 24 and by reason of the action of sprin s 28 causing the shoes 18 to be thrown quic lzly in a downward direction. Wedge members 16, coacting with the rollers 15, give the shoes 18 a lateral as well as downward movement and tend to throw the entire sash laterally in the opposite direction. Fin 13 is thus rigidly clamped between the shoe 18 and the adjacent wall of the channel 11 and the sash firmly locked, so as to retain its position even though subjected to the most severe jarring and vibration.

The closing of the sash is effected by merely pressing the sash downward by handle or lift 43, the wedge 18 automatically releasing the lockingmechanism upon the sash being moved in this direction without necessitating the use of the finger-levers.

Should a breakage occur in suspending bands or tape 5 or in the spring-drums or other devices designed to furnish power whereby sash 1 may be automatically raised, spring will rock bell-crank lever 57 upon stud 58, forcing friction member 62 upward,

and screws 64, extending through cam-slots 63, will throw the same laterally and press it firmly into engagement with fin 13, thus preverging thereby the accidental descent of the sas It will be seen that by reason of the clamping action of the above-described frictional locking means and the large engaging surfaces the sash, although instantly released by the most simple manipulation, is nevertheless rigidly held in any desired position.

' By reason of the wedge action of the locking member, moreover, in the present instance in which the window is overbalanced in such manner as to tend to draw the same upwardly upon free sliding movement being permitted, any such tendency effects merely a more secure locking of the sash, as it draws the wedge more snugly between the coacting parts. As no latches or lugs upon the fixed members are required in the above mechanism, moreover, the number of locked positions of the window is unlimited and the same may be adjusted to admit precisely the desired amount of air and efficiently locked in such position. The entire action, moreover, is instantaneous and automatic,

and the manipulation of the positive as well as frictional lock is of the simplest character, it being necessary merely to compress the members by which the sash is seized in order to raise or lower the same.

' Another advantageous feature of my invention resides in the fact that the locking devices are mounted upon the sash itself, enabling them to be placed in operative position therein before the sash is inserted in the frame. Should it for any purpose be necessary to repair or replace any of the cooperating parts, such repair or renewal may be easily effected by simply removing the sash from the frame.

It will thus be seen that I have provided mechanism which is well adapted to accomplish the several objects of this invention and that the same is not only of the most compact and durable construction, but is thorou hly reliable and efficient in action and we 1 suited to meet the somewhat severe conditions incident to use of apparatus of its nature.

As many changes could be made in the above construction and many apparently widely different embodiments of my inven tion could be made without departing from the scope thereof, I intend that all matter contained in the above description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense.
