WEIGHT-MOTOR.

To all whom it may concern:

Be it known that I, GUSTAV SCHWARTZ, a citizen of the United States, residing at Tampa, in the county of Hillsboro and State of Florida, have invented new and useful Improvements in Weight-Motors, of which the following is a specification.

This invention relates to weight motors and the object of the invention is the provision of a simple and efficient device of this character wherein the mechanism is so constructed that relatively high speeds may be obtained and the exact number of revolutions readily determined for each driven shaft.

A further object of the invention is a provision of a weight motor having a plurality of driven shaft-s each so connected to the driving shaft that its speed may be determined, and an escapement mechanism which effectively regulates the rotation of the driving shaft and which may, in turn, be properly controlled.

A still further object of the invention is the provision of an escapement mechanism in a motor of this character together with a stopping mechanism for the escapement which, when released, will give the initial movement to the escapement wheel, so as to start the motor in operation.

Further objects of the invention will appear as the following specific description is read in connection with the accompanying drawings, which form a part of this application, and in which Figure 1 is a vertical section through the machine. Fig. 2 is a horizontal section taken on the line 2-2 of Fig. 1 looking in the direction of the arrows. Fig. 3 is a bottom plan view with certain of the driven shafts omitted. Fig. 4: is a detail sectional view showing the escapement mechanism. Fig. 5 is a detail sectional view showing the pawl and ratchet arrangement andthe gear connection between the driving shaft, the escapement mechanism and the driven shafts. Fig. 6 is a similar view showing a modified form of driving connection. Fig. 7 shows a modified form of motor. Fig. 8 is an elevation on a reduced scale of the motor shown in Fig. 1. Fig. 9 is an elevation of a modified form of casing and motor.

Referring more particularly to the drawings, and especially to Figs. 1 to 5, 1 represents a suitable ceiling rosette to which Specification of Letters Patent.

Serial No. 627,650.

is secured a supporting tube 2 having telescoped therein a similar tube 3 which is ad justably connected to the tube 2 by means of a clamping band 4. Mounted upon the lower end of the tube 3 and open to communication therewith is a casing 5 which may be of any suitable outline and which is provided with a door G'hinged to one side thereof, so that access maybe had to the interior of the casing for purposes of lubricating the parts or for disconnecting certain of them from the driving shaft or obtaining different speeds, or for the purpose of replacing them when repairs are needed. I

Extending across the casing 5, adjacent its bottom, is a platform 7 upon which is mounted a vertical partition or hearing plate 8 connected to the platform 7 and to the top of the casing. This partition or hearing plate has journaled therein one end of a drum shaft 9 whose opposite end is journaled in the casing 5 and which extends through the casing on the side of the partition 8 and is squared so as to receive an operating icrank 10. Mounted upon the shaft and rotating therewith is a drum 11 around which is wound a cable or chain 12 which passes up through the tube 3 and over suitable antifriction rollers 13 mounted in brackets 1 1 supported upon a platform 15 extending across the tube 2. The depending end of the cable 12 has secured thereon a plurality of weights 16 in such a manner that they'may be removed or additional weights applied as is found necessary.

Keyed to the shaft 9, adjacent the drum 11, is a ratchet wheel 17 and loosely mounted upon the shaft and held against the ratchet wheel by a collar 18 is a gear 19 carrying a spring pressed pawl 20 which rides idly over the ratchet wheel when the cable is being mounted upon the drum and when the drum is operated by the weight positively engages the ratchet wheel so that, as the same is moved, the gear 19 will be rotated. This gear meshes with a pinion 21 carried by a transverse shaft 22 which also carries a pinion 23 having an equal number of teeth with the pinion 21 and meshing with the gear 24 upon a parallel transverse shaft 25. The gear 24 meshes with a pinion 26 upon a shaft 27 journaled in the sides of the tube 3 and carrying an escapement wheel 28 which is controlled by the rocking lever 29 in turn operated by the pin 30 on the hair spring wheel 31. A suitable goose. neck spring 32 is connected to the casing 5 and secured to the outer or free end of this spring is a simi larly shaped spring 33 having its outer end curled, as at 34, to engage the escapement wheel 28. The lower end of the spring 33 has connected to it a cable 35 whose lower end is provided with a plurality of balls 36 and 37 and an operating handle 38. The cable passes through the bottom 39 of the casing and through a plate 40 having a keyhole opening 41 therein, whose lateral slot is of a size with the cable and smaller than the balls 36 and 37, so that, when the cable is pulled downwardly and the ball 36 bridged across the lateral slot of the keyhole opening, the curled end 34 of the spring 33 will be engaged with the escapement wheel 38 and the rotation thereof stopped. When the cable is released the spring 32 will lift the spring 33 and the curled end, being engaged with a tooth of the escapement wheel, will rise and give the escapement wheel the initial starting movement.

Extending across the casing and arranged in parallelism with each other are a plurality of driven shafts 42, 43, 44, 45, 46 and 47, all of which have their ends journaled in the casing and the vertical plate 8 respectively. Each of the shafts 42 to 46 inclusive carry similar gears 48 and pinions 49, while the gear wheel 47 carries a pinion 50 to mesh with the gear 48 upon the shaft 46 and also a beveled gear 51 to mesh with the similar gear 52 upon a vertical shaft 53 which is journaled in the platform 7 and in a suitable bearing 54 carried upon the bottom 39 of the casing. The pinion 49 upon the shaft 42 meshes with the gear 19 and the gear 48 upon this shaft meshes with'the pinion 49 upon the shaft 43. This arrangement is followed out from the shaft 42 to the shaft 46 and, in order to avoid offsetting the gears each time, and to place them in as straight a line as possible, the,

pinions 49 upon the shafts 43 and 44 are upon the right hand side of the gears instead of on the left, as are the pinions upon the other shafts.

The shaft 53 passesthrough a collar 55 secured to the under side of the platform 7 and has secured thereto, intermediate the platform and the bottom 39, a large bevel gear 56 which is adapted to engage and operate suitable bevel gears 57 carried upon radiating shafts 58, whose inner ends are journaled in the collar 55 and whose outer ends are journaled in suitable bearings 59 and are limited from outward movement by means of collars' 60 keyed to the shafts and resting against the bearings 59. All of these shafts 58 and the shaft 53 are shown as carrying fans 61, but it will be obvious that or lowered, as desired. When the casing is raised to a point where the handle 10 is inaccessible, the handle 62 may be used for winding the drum. This handle is connected to the lower end of a shaft 63 which projects through the bottom 39 of the casing and has its upper end journaled in the bearing 64 and carrying a bevel gear 65 which meshes with a similar gear 66 upon the shaft 9. If desirable, the clutch connection may be formed between the shaft 63 and the gear 65.

In the modification shown in Fig. 6, the drum shaft is indicated at 67, and loosely mounted upon the shaft is a sprocket wheel 68 which is connected to the sprocket pinion 69 on the driven shaft 7 O by a sprocket chain 71. The driven shaft 70 carries a sprocket wheel 72 which is, in turn, connected to the succeeding driven shaft 73 by a sprocket chain 74. This arrangement is followed throughout the entire train of reducing gears, as shown in Fig. 1. v

In the modification shown in Fig. 7, suitable shaft hangers 75 are supported from a ceiling 76, or other suitable support andhave bearings in their lower ends to receive the drum shaft 77. The drum shaft carries a long drum 78 and a ratchet wheel 79, and

loosely mounted upon the shaft is a gear wheel 80 which is interposed between the ratchet and drum and carries the pawl 81 which is spring pressed into engagement with the ratchet 7 9. The drum has wound ioo thereon a plurality of cables, here shown to K be three in number, 82, 83 and 84, all carrying weights 85 which act in unison to rotate the drum. A reducing train of gears 86 is connected to the gear 80 and to a transmission shaft87 upon which loose and idle pul- M ,l

leys 88 and 89 are mounted. These pulleys may be belted to any desired mechanism.

In the modification shown in Fig.9 the casing and weight tube are supported upon a base 90 and, in this instance, the entire izb the driving shaft, a weighted cable wound 7 around the drum, a second casing slidably mounted on the main casing, friction pulleys carried in the second casing for supporting the weighted cable, means for adjusting said second casing on the main casing, an escapement mechanism for controlling the operation of the drum, a plu- In testimony whereof I affix my signature rality of horizontally mounted driven shafts in presence of tWo Witnesses. intergeared With the driving shaft, a verti- GUSTAV SCI'UVARTZ. cal shaft geared to the last horizontal shaft, Witnesses:
