To @ZZ whom t may concern:

Be it known. that I, ALVIN Q. WOLF, a citizen of the United States, residing at Dayton, in the county cf Montgomery and State of Ohio, have invented certain new and useful Improvements in Sash- Operating Mechanism, of which the following is a specifi cation, reference. being had therein to the accompanying drawings.

This inventiony relates to improvements in sash operating mechanism designed especially for-use in hot or green houses, where a.

number of sashes are employed.

The several essential objects of the invention and the devices by which these objects are carried into practice are, first, a system of hangers and braces attachable to the ridgepole of the greenhouse-roof and adapted to su port and brace operating mechanism at eit er side of the ridge-pole, according to whichever side of the building the sashes are located; second, a system of operating-gears and sprocket-wheels adapted to be located in part at the end of the building and in part to be suspended from the ridge-pole and working in conjunction with a peculiar cable, one branch of which operates the sash-rods and is supported from sagging, and, third, to numerous minor features of detail, allas hereinafter more fully described and particularly pointed out in the claims.

In the accompanying drawings, forming a part of this application, and on which like reference-letters indicate corresponding parts,

Figure l. is a side elevation of my operating mechanism, showing a partial interior view of a portion of a greenhouse with the apparatus applied thereto. Fig. 2 is a detail enlarged perspective view of a bracket used to suspend the cable-supporting rods; Fig. 3, a detail enlarged perspective view of a sashbar; Fig. 4', a detail enlarged perspective view of a sash-clip which may be used instead of the bar; Fig. 5,an enlarged side elevation of one of the sash-bars; Fig. 6, a partial elevation and sectional view, on a still larger scale, of one of these bars Fig. 7, an end elevation of the interior of a greenhouse, showing the operating devices for the cable also in elevation Fig. 8, an enlarged detail side view and partial sectional view of one of the supporting or hanging devices for the cablesprocket; and Fig. 9, an end elevation of the same parts, showing more particularly their relation to the ridge-pole of the roof.

i The letter A designates a portion of a'green I or post, but braced to the ridge-pole. Thev hangers, specifically speaking, consist of a bar D, hung on a pivot-bolt E from a bracket F, bolted or otherwise secured to the ridgepole, This bracket extends to one side of the ridge-pole in an angular direction, as seen more clearly in Fig. 9, so that by turning the bracket end to it may be made to project from one side or the other, so as to suspend the hanging devices likewise to one side or the other. A brace G is connected by a bracket Il and bolts or screws to the bar D and is also connected by a bracket I of similar construction to the bracket F and adapted to be connected to the ridge-pole and to extend to one side thereof, as in the case of the lbracket F. The connectionbetween the brace Gr and the bracket I is preferably pivotal by means of a bolt J. To the lower end of the bar D is secured a plate K, to which is pivoted a bearing-lever L, the supporting sprocket-wheel IVI being mounted eccentrically for a purpose hereinafter named on this lever at its lower end, while its other end is adjusted by a nut and bolt N, so as to take up the slack and create suflicient tension in the operating-cable composed of sections of sprocket-chains O and P and intermediate sections of rods At suitable points along the greenhouse and to the frame thereofdsay to the under side of the ridge-pole-brackets R are secured, having a number of holes S, into either of which a cable-brace T is hooked at its upper end, while its lower end engages one of several holes in a clip U, secured to the lower cable-rod Q. A second cable-brace V is engaged'with a staple or eye W, supported by one of the rafters, and also with one of the openings in the clip U. The upper ends of these cable-braces T and V are somewhat separated, while their lower ends are quite close together, and they are so situated that they will allow the cable to be adjusted in eith'er direction, swinging on their pivots as the cable moves. Their purpose is to brace TOO IIO

the cable against swaying off to one side when the sash rods or lifters X are exerting a force in lifting or holding open the sashes to which at one end they are connected, while at the other they engage with one of the openings in the bracket U. The position of the sash lifters or rods is at an angle to the rafters, so that when the lower end of the same is moved by the cable the sashes will` be lifted or lowered according to the direction of movement. The sashes are indicated at Y, and the connection of the rods or lifters X therewith may be either through the sashbars Z, which are secured to the sides of the sash-frame and have openings a, in either of which an eyebolt b is secured for connection with such rods or lifters, or by means of a sash-clip c, designed to be secured to the llower bar of the sash-frame and having an opening, in which is secured the eyebolt b for the purpose stated. Either this sash-bar or sashclip may be used, according to the weight of the sash or the particular situation. It will now be seen that the sashes are controlled by these rods or lifters X and that the cable is braced at the points of attachment of the rods therewith, yet that the cable is free to be adjusted longitudinally back and forth. This brings me to a description of the mechanism employed to operate this cable. It consists of a column or post cZ-say in the nature of a stout pipe-secured at its lower end to a post or part of the frame e by a clip f, and at its upper end secured to the ridge-pole by a short arm g, which may be turned on the column d, so that the column may be set to either side of the ridge-pole, while the arm extends over to the pole. This column carries a stout bearing-plate h, clamped to the column by means of a clip i and bolts This bearinglate 7L carries a reversiblefork c, connected t ereto by bolts and nuts Z and bolted to' a brace m, which extends up and is secured to the ridge-pole. As seen from Fig. 7, this reversible fork 7c extends to one side of the column d, so that although the brace m is directly under the ridge-pole it connects with and braces the column and bearingplate which stand to one side of the ridgepole. This brace m and fork 71e, together with the hanger D G, constitute the hanger and brace devices referred. to hereinbefore.

By reason of the construction which I have described the operating mechanism may be laterallyv offset to either side of the vertical plane of the ridge-pole, and the cable may be corres ondingly offset so as to bring it more directfy under the sashes. This position of the cable is obviously advantageous, for the reason that excessive lateral thrust on the cable is avoided and the connections between the cable and sashes may be materially shortened, while the movements of said connections are more nearly in the plane of movement imparted to the sashes.

' the other.

Referring now speciiically to the cable-operating mechanism, it will beseen that in the bearing h there is mounted a shaft n, carrying a sprocket-pinion o and a bevel-gearwheel p. On this sprocket-pinion is mounted the sprocket-'chain P, so that when the pinion is rotated in one direction or the other the entire cable is moved in one direction or The arts are so adjusted that the sashes will be lifted to their extreme open position when the stop g on the lower branch of the cable comes into contact with one of the teeth of the pinion o, and so that the sashes will be in their closed position when the stop r on the lower branch of the cable comes into contact with one of the teeth of the pinion 0. A bevel-pinion s meshes with and drives the bevelgear p, and as the pinion 0 is united to the bevel-gear p rotary motion is thus given said pinion. The bevel-pinion s is mounted upon an operating- I shaft t, having a bearing at its upper end in a yoke u, suspended on the ends of the shaft n. The lower end of the shaft t is mounted in a lower bearing-plate i), held to the column d by means of a clip w and nuts and bolts This bearing-plate 'v also carries a fixed studshaft y, on which is mounted a hand-wheel z, carrying a bevel -pinion z and a ratchetwheel y. This bevel-pinion meshes with a crown-wheel t on the lower end of the shaft t. By these devices rotary motion is imparted to the operating-shaft t, and thence to the other parts, as above indicated. To lock the parts in any adjusted position, a pivoted detent fr is dropped into the ratchet-wheel y. An arm w, carried by the stud-shaft y, supports the detent x.

Referring again to the detail character of the construction of the sash-rods X, attention is directed to Figs. 5 and 6, wherein this rod is shown in detail. It will be seen that it is divided into two parts, one of which, X, is hollow to receive the other part, while any one of the series of holes in the part X will receive a pin Y, the pin passing through a hole IOO IIO

in the other part of the rod, whereby the length of the entire rod may be made greater or less to suit the particular situation where the apparatus may be mounted.

The mode of operation of my apparatus will now be undertsood, and I need only therefore add that it is effective in use and safe and reliable in its control over and adjustment of the sashes, both with regard to holding them open or partly open and holding them closed. The sprocket-wheel M being mounted eccentrically, as before stated, and as shown in Fig. 1, it will be seen that as the lower branch of the rod or cable moves to the left the wheel will revolve, bringing the shorter or minor radius thereof over to the right, thereby lengthening the cable and compensating for the arc described by sash-rods X as they swing to lift the sashes. As shown in Fig. 1, the sashes are partly up and the stop g and wheel M are in corresponding positions.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, isd
