WEIGHT-MOTOR.

Specification of Letters Patent.

Patented Apr. 2Q, 1915..

Application filed September 11, 1912. Serial No. 719,783.

To all whom it may concern:

Be it known that I, CHARLEY MCQUEEN, a citizen of the United States, residing at San Antonio, in the county of Bexar and State of Texas, have invented new and useful Improvements in l/Veight-Motors, of which the following is a specification.

The general object of this invention is the provision of a fan which includes a casing having a weight motor mounted therein which comprises a novel arrangement of gearing and which is adapted to be wound and regulated in an improved manner; and to this end the invention consists in certain novel constructions, arrangements and combinations of devices which will be described hereinafter and then pointed out in the appended claims.

In carrying out the object of the invention generally stated above, it will be understood, of course, that the essential features thereof are susceptible to changes in details and structural arrangements, one preferred and practical embodiment being shown in the accompanying drawing, wherein Figure 1 is a side elevation of the fan constructed in aocordancewith the invention. Fig. 2 is a vertical section through the upper portion of the casing for the fan, showing the motor in elevation. Fig. 3 is a fragmentary View of the casing and the means for decreasing the speed of or stopping the motor. Fig. 4 is a vertical sectional view through the casing, showing a modified form of motor. Fig. 5 is a detail side elevation of the motor shown in Fig. 4, looking in the direction of the arrow, to the left thereof. Fig. 6 is a view similar to Fig. 5 looking in the opposite direction.

Referring more particularly to the accompanying drawings, in which like reference characters designate similar parts, it will be seen that the invention comprises an elongated tapering casing 10 having the handles 11 secured thereto whereby the fan may be moved from place to place as desired. The casing 10 is provided with the enlarged base 12 which is preferably made of some relatively heavy material so that the casing will maintain its equilibrium when the fan is in use. The extreme upper end of the casing 10 is provided with a bearing 13 through which passes the vertically ar ranged shaft 14 having the shoulder 15 thereon for limiting the inward movement of said shaft, and secured to the outer extremity of the latter are a plurality of fan blades 16 and 17. By referring to Fig. 1 it will be seen that the fan blades 16 and 17 extend in opposite directions above and below a horizontal plane and are so pitched that air currents will be driven above and below the said blades and to each side thereof.

The mechanism for driving the shaft 14 is mounted in the upper portion of the casing 10 and in the form illustrated in Fig. 2, said mechanism comprises a pair of superposed shafts 18 and 19 which extend transversely of the casing and which are mounted in bearings 20. Intermediate the ends of the shaft 18, the same has secured thereto a drum 21 having a cable 22 wound thereon, the free end of said cable being provided with a weight 23. The shaft 18 also has fixed thereon a sprocket wheel 24 over which is trained an endless chain 25, the latter being also trained over another sprocket wheel 26 mounted in the lower portion of the casing 10, the last named sprocket wheel being driven by means of a crank handle 27. It will thus be seen that by rotating the crank handle 27, a similar movement will be imparted to the shaft 18 whereby the cable 22 may be wound upon the drum 21.

Upon the release of the crank handle 27 the weight 23 will cause the shaft 18 to r0- tate in an opposite direction and through the medium of the gear wheels 28 and 29, the latter being fixed upon the shaft 19, the latter will also be caused to rotate. In order to impart a rotary motion to the vertical shaft 14, the latter is provided at its inner end with a beveled gear 30 which meshes with a similar gear 31 carried by the shaft 19. It will thus be seen that through the medium of the mechanism just described, the fan blades 16 and 17 may be rapidly rotated.

It may be often found desirable to stop the fan before the weight 23 has reached the limit of its downward movement and to this end there is provided a stopping device which includes a drum 32 mounted upon the shaft 18 adj acent. the drum 21, said drum 32 having a resilient band brake 33 partially surrounding the same. Ihe free ends of the brake 33 are provided with an opening adapted to receive one end of an operating cord 34, the other or lower end of said cord extending through an opening 35 adjacent the lower end of the casing 10. Adjacent the opening 35, the casing 10 has stamped therefrom a clip 36 which is bent so that when the cord is pulled downwardly, the handle 37 may be caught beneath said clip. By exerting a downward pull upon the cord 34 it will be seen that the resilient band 33 will be drawn closely about the drum 32 thus tightly gripping the same and preventing rotation of the shaft 18 which will of course stop the fan blades 16 and 17 from rotating.

Referring now to Figs. 4, 5, and 6, in which there has been shown a slightly modilied form of motor, it will be seen that the casing 10 is provided with an inwardly extending bracket 38 having a shaft 39 journaled therein, the latter having fixed thereto a drum 40 upon which a cable 41 is adapted to be wound, said cable being provided at its lower end with a suitable weight 42. The shaft 39 also has fixed thereon a gear wheel 43 which meshes with a similar gear wheel 44 carried upon the shaft 45 which is journaled in the bracket 46 also carried by I the casing. The gear wheel 44 is rotated in order to impart a similar motion to thedrum 40 by means of the beveled gears 47 and 48, the former being fixed upon the shaft 45 while the latter is fixed upon a vertically arranged shaft 49 which is journaled in the bearings 50 and 51 which extend inwardly from the side of the casing 10. The lower end of the vertical shaft 49 is also provided with a beveled gear 52 which meshes with a similar gear 53 carried upon the inner end of the crank handle 54 a portion of which projects through the casing 10. It will thus be seen that by rotating the said crank handle 54 in one direction, the cable 41 may be wound upon the drum 40 so that the weight 42 may be hoisted to the limit of its upward movement. When the crank handle 54 is released the drum 40 will rotate in an opposite direction through the medium of the weight 42 which will start its downward movement and rotation of the drum 40 will impart a similar movement to the gear wheel 55 through the medium of the gear wheels 43 and 44, the latter meshing with the said gear 55. The gear wheel 55 is fixed upon a shaft 56 which is journaled in a transversely extending supporting bar 57, the latter being provided at its ends with the laterally extending flanges 58 which are adapted to abut the casing and be.v secured thereto. Secured to the casing 10 at a point approximately opposite to the brackets 38 and 46 is another bracket 59 having shafts 60 and 61 journaled therein, the former being provided witha gear wheel 62 which meshes with the gear wheel 55 while the latter is provided with a similar gear wheel 63 which meshes with the gear wheel 62. At a point in the casing above the bracket 59, there is secured another bracket 64 having a shaft 65 journaled therein, the latter having seotured thereto a gear wheel 66 which meshes with the gear wheel 63 and a worm wheel 67 which meshes with a worm shaft 68. The latter is mounted upon the vertically arranged shaft 69, which corresponds to the shaft 14 in Fig. 2, and is spaced from the bearing 70 by means of the bushings 71. It will thus be apparent that, through the medium of the gearing just described, the shaft 69 will be rapidly rotated thus causing the fan blades which are secured thereto to generate the different air currents. The form of the invention illustrated in Figs. 4, 5, and 6 is also provided with a brake mechanism such as was described in connection with Fig. 2 and this brake mechanism includes a drum 71 which is mounted upon the shaft 61. A resilient band brake partially surrounds the drum and the free ends of said band are provided with openings through which are passed the operating cord 7 2, said cord being secured to the casing 10 as previously described and illustrated in Fig. 3 of the drawing.
