Application filed November 27, 1912.

To all w 7mm it may concern:

Be it known that I, Josnrn B. STRAUss, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Operating Mechanism for Windows or the like, of which the following is a specification.

This invention relates to operating mechanism for windows, etc., and has for its object to provide a new and improved device of this description.

The invention is illustrated in the accompanying drawings, wherein Figure 1 is a view of a window provided with the operating mechanism; Fig. 2 is a sectional view taken on the line. 2-2 of Fig. 1. Fig. 3 is a view similar to Fig. 2 showing two sashes each counterbalanced by separate counterweights. Fig. t is a View of one of the side frame pieces carrying the racks and pinions; Fig. 5 is a view showing a construction where there are two adjacent windows; Fig. 6 is a sectional view showing the operating mechanism in connection with sashes counterbalanced by vertical counterweights; Fig. 7 is a view showing the locking device for the construction shown in Fig. 6; Fig. 8 is a sectional view taken on line 8-8 of Fig. 6.

Like numerals refer to like parts throughout the several figures.

The particular operating mechanism herein shown may be used in connection with various devices but for purposes of illustration I have shown it in connection with windows. As shown in Fig. 1 there are provided two sashes or sliding

sections

1 and 2. These sliding sections are each provided with a rack 3 having a portion 4: connecting with the sections. Each rack is contained within an inclosing case 5 having a slot 6 through which the portion 4: of the rack projects. This inclosing case may be made in any desired manner and as herein shown consists of a single piece of material but bent around into an inclosing case preferably of a rectangular shape the two edges separated so as to form the slot 6. This casing forms, as it were, a single unitary cell in which the rack is carried. The edge 7 is preferably bent so as to act as a retaining part for the rack. There is a separate and independent casing or cell for each rack. Located between the casing or cell 5 is a pin- Specification of Letters Patent.

ion 9 which projects through openings in the casings 5 the teeth thereof engaging the teeth of the racks 3. This pinion is carried by a bracket 10 fastened to the two casings or cells 5. The pinion 9 is mounted upon a pin 11 carried by the bracket 10 and is held in place by the removable plate 12. By this construction the pin can be removed from the inside of the frame piece. The two casingsor cells 5 are connected together by the bracket 10 and are also connected together preferably at the top and bottom by suitable cross-connecting pieces 13. This forms a unitary structure or side frame piece made up of the casings or cells 5, the racks 3, the pinion 9 and the cross-connecting. piece between the casings or cells 5.

This forms a simple and cheap side frame piece using a small amount of metal which may be easily manufactured and which incloses and guides the racks in all their various positions. These side frame pieces can therefore be made up at the point of manufacture and shipped to the point of use and there installed the racks being fastened to the parts in connection with which the operative mechanism is to be used.

In Fig. 3 I have shown a construction similar to that of Fig. 2 except that instead of two sliding sashes I show a single sash 14E counterbalanced by a counterweight 15 one rack being connected to the sliding sash and the other to the counterweight.

By means of the construction shown, for example in Fig. 2, the windows of the building may be placed side by side the side frame pieces made up of the cells 5 of the two windows being the only parts between them, thus permitting them to be placed very close together as these side frame pieces are comparatively thin.

In Fig. 5, I have shown a construction where there is a window with sliding sections and an adjacent window with a fixed section. In this construction, the rack cases of the sliding sections are fastened to the, sash frame 16 of the fixed section. There may be an intervening plate or piece 16, the

rackcases and plate forming a mullion as it were, which is thin, strong and easily placedin position. The sash pieces or frames 16 16 of the sliding sections may be of metal as well as the sash frame 16 and the piece 16, thus forming in a metal window a combination support for a fixed sash and a sliding sash, said support comprising an operating device for the sliding sash and a side frame or sash piece for the fixed sash, the two secured together so as to form a mullion.

In Fig. 6 I have shown a construction where each

sash

1 and 2 is provided with a separate vertical counterweight the sash 1 havinga counterweight 17 and the sash 2 the counterweight 18 In this construction the operating devices consist of the cells 5, the connecting pieces, the racks and the pinion in a plane substantially parallel with the sliding sections or sashes. The racks in this case which are connected to the sliding sections are offset. They are provided with portion which engages the pinion and a portion substantially parallel thereto which engages the sliding section and an angular piece 19 which projects through the slot and connects the other two pieces. The vertical concrete counterweights are connected to the other racks and work in a space at the side of the sliding sections and between the operating mechanism for the sliding sec tions and are guided by said operating mechanism. These counterweights are provided with means for adjusting their weight was to permit the exact counterbalancing of the sliding sections. In the construction shown, the counterweights are provided with adjusting pockets 20 into which concrete or other adjusting material may be placed to secure an exact counterbalancing effect. This may be done after the parts are installed. In the construction of Fig. 6, the sliding sections normally move independently. It is desired to connect them so that when one is moved the other will be moved in an opposite direction, the connecting piece 21 on one sliding section may be moved in so as to enter a receiving opening in the counterweight of the other sliding section. This connects the sliding sections so they operate simultaneously. If it is desired to lock the sliding sections so that neither can be operated a hook 22 is connected to the connecting piece 21 when it is in its locking position, see Fig. 7 I prefer to provide an engaging part between the two counterweights which permits relative movement thereof, such as the ball 23, which works in grooves 24: in the counterweights (see Fig. 8). It will be seen that the operating mechanism herein shown is capable of a wide use and-adaptation.

I have shown my invention as applied to Windows, and I have used in the clalms the Word windows. I use this term to include separated cases made up of metal bent into shape, the edges of the metal at one side of each case being separated to form a slot extending longitudinally along the case, racks inclosed within said cases and having parts projecting therefrom through the space between the edges thereof, means for connecting said cases together so as to hold them in rigid relation with each other, a pinion located between the cases and projecting into said cases through openings therein so as to engage said racks.
