Application filed July 18,

To all whom it may concern:

7 Be it known that I, CHARLES E. OUILLETT, a citizen of the United States, residing at Lowell, in the county of MiddleseX and State of Massachusetts, have invented certain new and useful Improvements in Elevators, of which the following is a specifi cation. 7

This invention relates to elevators, and an object of the invention is to provide an elevator operatingmechanism for raising and lowering the cage of the elevator, which does not employ cables, hydraulic columns or analogous structure, ,the prime'mover or operator or elevating or lowering mechanism being carried beneath the bottom of the cage and receiving its power through. suitable. conductors carried by theupright beams of the elevatorstructure.

A further objectof the invention is to provide a comparatively simple control for con-,- trolling the direction of 'movement of the cage. 1 1 r A further object is to provide an elevator structure as specified which is comparatively simple in construction, and consequently may be installed at a relatively low cost,- as wellas one in which liability oflaccident due to the falling of the cage is eliminated, the means for transmitting the elevating or low ering movement to the cage being suchthat in" case any part of the mechanism breaks, the said means will support'the cage without. any drop whatsoever, at the point at which it was when the breaking occurred.

Other objects of the invention will appear in the following detailed description, taken. in connection with the accompanying drawings, forming a part of this specification, and in which drawings: Q

Figure 1 is 'a fragmentary vertical section through the elevator mechanism;

Fig. 2 is a fragmentary vertical section through. the elevator mechanism taken atv right angles to the section illustrated in Fig. l, and p Fig. 3is-a bottom plan of the elevator cage I illustrating the operating mechanism therefor. V v i.

Referring more particularly tothe draw-- ings, wherein like characters indlcatelike and correspondingparts throughout the several views, 5 land 6 indicate the upright beams of the elevator structure which beams have vertically extending racks 7 carried by their facing sides, with which racks worms Specification of Letters I'atent.

are positioned. one at each respectively. The shafts 12 and 13 are rotatably supported. by suitable hangers 14 which are suspended from the floor beams 15.0f the cage structure 10. W'orm gears 16 are mounted upon the upper ends of the shafts 12 and 13 and they mesh with. worms 17 mounted on the opposite ends of theshaft 18. The shaft 18 is rotatablysupported by suitable bearings 19 carried by cross beams 20 and it-v has sprockets 21 and 22 mounted thereon about which sprocket chains 23 and 24 travel.. The sprocket chain 23 travels about a sprocket carried by the stub shaft- 25, which stub shaft carries a gear 26 which meshes with a gear 27 mounted upon the hub 28 of a clutch section 29. The-clutchsection 29 1S rotatably mounted upon the main power shaft 30 of the prime mover or electri'cal motor 31, and is operatively connected tosaid shaft for rotation thereby upon interengagement with the clutch section .32. I The clutch section 32 is feathered upon the shaft 30. and has a shifting arm 33 connected thereto which is in turn connected to the shifting rod 34. The provision of the gears 26 and 27 will rotate the shaft 18 in a direction reversely of the direction of rotation of the shaft30 when'the clutch sections 29 and 32 arein inter-engagement with each other. The'shaft 18 is rotated in the same direction in which the shaft 30 is rotated through the medium of the sprocket 22, chain 24, .and sprocket 35.; The sprocket 35' is mounted upon the hub 36 of a clutch section 37 which is rotatably mounted upon'jthe shaft 30. and

clutch section 38 feathered upon the shaft 30, A shifting arm 39, is connected to the feathered clutch section 38 and to theshifting rod 34 drawings. and 41 connected toits opposite ends, and

the cable 40 passes abou'ta suitable sheaf or.

is adapted for inter-engagement with a as clearly shown in Fig. 3 of the A shifting rod 34 hascables 40 connection to the cable 40 and the lever, so that when the lever 43 is moved in one direc-' tion or to the left of Fig. 2 of the drawings, it will slack the cable 41 and tighten the cable &0 for shifting the rod 3 1 to move the clutch section 38 into inter-meshing engagement with the clutch section 37, and move the clutch section 32 away from the clutch section 29, while if the lever 13 is moved in the opposite direction or to the right of Fig. 2 it will shift the rod 3 to move the clutch section 32 into meshing engagement with the clutch section 29 while the clutch section 38 is moved away from the clutch section 37, and thus by the shifting of the lever 43 the direction of'movement of the elevator cage 10 is determined.

Electrical current conducting rails 47 and 18 are carried at the sides of the upright beams 5 and 6 respectively and contacting rollers 49 and 50 are yieldably supported at opposite sides of the elevator cage 10 and ride over the rails 47 and 48 respectively. Suitable conducting wires 51 and 52 are connected to the rollers 50 and to the-opposed poles or. terminals of themotor 31 for conveying the energizing current fromthe rails 47 and 48 to the motor to operate the latter for rotating the shaft 18 and from this shaft the vertical stub shafts 12 and 13 which carry the worms Sand 9. The rotation of these worms 8 and 9, will owing to their meshing engagement with the teeth of the racks 7, either elevate or lower the cage 10, depending upon the direction in which the worms are rotated.

Suitable guards 53 are provided for the rails 17 and 48.

A housing 56 is attached to the bottom of the cage 10 for inclosing the elevator operating mechanism, and it has one portion 57 hingedly connected as shown at 58 to the main body of the housing to permit access to the interior of the housing and consequently to the elevator operating mechanism. A chain or an analogous flexible device 59 is provided for limiting the opening movement of the door 57 of the housing.

Safety bumpers 60 are provided at the bottom of the elevator pit, as is usual in elevator structures.

Changes in details may be made without geparting from the spirit of this invention,
