CLAUDE L. HAGEN, OF NEW YORK, N. Y.

ELEVATING AND LOWER-ING- DEVICE FOR STAGE-SCENERY.

To all whom it may concern.-

Be it known that l, CLAUDE L. Hxomv, a citizen of the United States, residing at New York city, in the borough of Manhattan, county and State of New York, have invented certain new and useful Improvemeats in Elevating and Lowering Devices for Stage-Scenery, of which the following is a clear, full, and exact description.

This invention relates to mechanism adapted to permit the handling of stage scenery with the use of little labor, and to readily permit the lowering of all scenery in a short space of time, in case of fire or other accident, when it is desired that the scenery should be lowered; for instance to the stage floor, that fire fighters may get at the same effectively.

In the theatrical profession, the handling of the scenery, which is often very heavy, requires the services of strong and sometimes a number of men to raise and lower the same, even when counterweighted to the best of the ability of the stage manager, for

besides the weight, the operators must overcome the friction over the sheaves. Tn the present invention, I secure this result by securing to each piece of scenery a counterweight, consisting of an open bucket, containing a flowing weight, preferably shot. l provide means for readily filling such bucket to overcome the friction on the sheaves, and the weight of the scenery, if desired to raise the same, or to counterbalance it to a nicety to enable the operator with little expenditure of energy to operate the same. If it is desired to lower the scenery, I provide a valve which allows the shot to run out of the bucket when the weight of the scenery will cause the same to gradually approach the stage either by its own weight or aided by the stage hand with little expenditure of energy.

To provide the apparatus with means to permit its operation as may be desired, I provide a conveyer system for elevating shot from a receiving well or hopper in the cellar. to the roof of the theater, where it is distributed in a trough, having pipes leading in line with each of the buckets, each bucket traveling vertically in a shaft or tube. The shaft or tube leads to a well or hopper preferably in the cellar of the theater, from which the shot is elevated by the Specification of Letters Patent.

conveyer, heretofore described. Haul ropes are fastened to the bucket to allow one to manually shift the bucket in the shaft or tube, and thus move the scenery. Trap ropes are provided to permit the exit of the shot from the buckets, that the scenery may descend by its own weight. Each bucket preferably has a number of ropes or cables leading thereto, which pass over sheaves arranged transverse to the stage, and are secured to a scene hanger provided with. suitable clutches for engaging the batten thereof. In order that the shot may be distributed in line with the various tubes or shafts, the trough may be provided with a distributing conveyer, to convey the shot to one end or the other of the trough. Each pipe or tube from the trough leads to an individual tube or shaft and is provided with a hand valve for manual control from a gallery to allow the shot to enter the buckets at will, or semi-automatical means for the operation of such valve may be provided. As the various ropes to the various positions on the scene hanger lead to an individual bucket, and it is necessary to have the scene hanger at all times level, I provide a new and improved equalizer for taking up slack in the different ropes or cables.

Various other details of improved con struction will be referred to in the specification.

The scope of my invention will be pointed out in the claims.

In the accompanying drawings, Figure 1 is a side view partly in section, showing my device as it appears against one of the side walls of the theater. Fig. 2 is a View partly broken away and partly in section, the main section being taken on line 22, Fig. 1. Fig. 3 is a detail of one of the equalizers for taking up the slack in the rope or cable, showing a side view thereof, with parts broken away. Fig. 4: is a view at right angles to Fig. 3 on line 4.4 of such figure. Fig. 5 is a transverse sectional side elevation of one of my improved buckets taken on line 5-5, Fig. 6. Fig. 6 is a sectional view on line 66, Fig. 5. Fig. 7 is a transverse sectional view enlarged of the supply trough, taken through the center of one of the valves. Fig. 8 is a sectional plan view taken on line 88, Fig. 7 of a portion of the supply trough. Fig. 9 is a detail partly in section, of the motor drive for the haul ropes.

As shown in the drawings, 1 is a piece of scenery known as a drop, generally provided with a batten at the top, shown by the line at 2, Fig. 1. A series of clamps 3 engage the batten, and they are mounted on a transverse pipe orbar 4. At various distances along this bar there are secured equalizers or cable take-ups 5, which will be described more in detail hereinafter. The cables or ropes 6 pass over sheaves 7, each of which is secured to a beam, near the roof of the theater. The collection of ropes shown in Fig. 1 at 5 pass over a large sheave or drum 8, down through a tube or shaft 9, and are attached to a link secured to a bucket 10. A chain 11 secured to the side wall and secured at its other end to the bottom of'the bucket, is provided to act as a counterbalance for the cables 6, after they pass over the sheave 8. A haul rope 12, passing over a sheave 13 near the top of the theater, is attached to the top of the bucket. The lower end of the haul rope passes over a sheave 14, which is mounted on a 13061115, and adapted to be clamped thereon in an adjustable position; from the sheave 14 the haul rope passes over a sheave 15 and is secured to the bottom of the bucket, so that upon pulling upon the haul rope the bucket can be raised and lowered and the drop also lowered and raised. Each one of the scene hangers, it will be obvious, may be supplied with its individual tube or shaft 9, and with its individual bucket 10. The shaft or tube 9 is open at its top and at its bottom. At its bottom it: leads to a hopper or receptacle 13, preferably having inclined bottom 14*, which delivers the shot, mercury or other material into a well adjacent to an elevator 15". The elevator may be of the ordinary bucket type, having two legs 16 and 17, composed of closed shafts or tubes, and may be driven by an electric motor 18 through worm gears 19, delivering theshot at its upper end through a tube 20, to a trough 21, shown in detail in Figs. 7 and 8, and which will be further described. The trough has a number of pipes 22, leading therefrom, one to the top of each of the shafts or tubes 9, and controlled by a suitable valve, so that the shot may be dropped into the bucket, and retained therein, causing the same to balance the drop. The bucket is provided with a trap 23 at its bottom, whichis operated through a trap rope 24, passing over a sheave 25 in thecellar and over'a sheave 26 near the roof, also passing freely through a tube 27 in the bucketso as not to be interfered with by the shot therein. The function of the trap rope 24 is to open the trap when it In View of the perfect balance secured it is unnecessary to secure the haul ropcor other parts.

The bucket is shown in detail in Figs. 5 and 6. It is composed of a chamber 28, through which the tube 27 passes for the trap rope 24, and with a solid bottom 25) open to a tube 30, provided with a slot 31. Surrounding the slot 31 is the tube 23 in.- tegral with a clamp bracket 33 secured to the trap rope 24. I prefer to provide the bucket at its upper partwith a funnel of leather or other material 35 to direct and cushion the shot as it falls through the tube or shaft into the chamber 28. I also prefer to provide a channel 36 at one side of the bucket, which will permit overflow to the hopper 13 in the cellar should more shot be fed to the bucket than it will hold. The channel 36 also permits freedom of motion for the counterbalance chain 11 heretofore described. The various drop cables or ropes 6 are preferably secured to a link 37 of the bucket, where they may be made fast in any of the usual ways known to mechanics.

The supply hopper 21 for the tubes 9 is made in the form ofan ordinary trough and is preferably provided with rails 37, across which a distributing carriage 38 may be pushed by hand or mechanically. The same is made with a flat bottom as shown in the drawings, which is sometimes necessary due to lack of overhead room. It is understood that such distributer will not be necessary in equipments where the shot will feed by gravity. provided in the trough an opening 38, which is normally closed by a slide valve 39, operated by a crank 40, rotated by a crank arm 41. While I have shown a manually operated crank arm for operating this valve 39, it will be obvious that other means may be employed.

The drop cable or rope 6, as I have before stated, is secured to an equalizer 5. This is shown in detail in Figs. 3 and 4. It comprises a pair of metal arms 42 clamped around the tube 4, and cut out to guide the cable 6 at its upper end as illustrated at 43, Fig. 4. A drum 44 is pivotally mounted in the arms 42, and to this drum the cable is permanently secured. At each side of the drum, preferably, I secure ratchet wheels 44 engaged by ratchets 45 under the tension of springs 46. A key 47 is provided to rotate the drum'to equalize the length of each of the cables 6, one with reference to the other, while the ratchets hold them in their adjusted positions.

As shown in Figs. 2 and 9 the haul rope 12 may be operated through an electric motor 49, which normally drives a pulley 54 loosely mounted on the motor shaft through pinions 50 and 52, and an internal gear 51. The gear 51 is normally locked to Above each tube or shaft there is the pulley 54 by a latch 58, provided with a spring 56. In this condition the haul rope is driven by its friction on the pulley around which it is passed, and in the case of trouble, such as fouling interference or entanglement, slip is allowed to prevent accident. If the haul rope is to be hand-controlled the latch pin 55 is withdrawn, rotated to cause the pin 57 to lie out of its recess, and leave the pulley free for rotation.

While I have for convenience termed the part 23 a trap, its function is that of a valve, it being obvious that any proper valve mechanism may be used.

In carrying out this invention, details of construction may be varied from those shown, and yet the essence of the invention be retained; some parts might be employed without others, and new features thereof might be combined with elements old in the art in diverse ways, although the hereln described type is regarded as embodying substantial improvements over such modifications.

As many changes could be made in the above construction, and many apparently widely difierent embodiments of the inven tion could be made without departing from the scope thereof, it is intended that all matter contained in the above descriptlon or shown in the accompanying drawings shall be interpreted in an illustrative and not in a limiting sense.
