ELEVATOR.

SPECIFICATION forming part of Letters Patent No. 367,226, date-d July 26, 1887.

' Application filed April 13, 1887. Serial No. 234,683. (No model.)

To all whom it may concern-.-

Be it known that I, ANDREW G. NEwToN, a citizen of the United States, residing at Oresceut,in the county of Saratoga and State of New York, have invented certain new and useful Improvements in Elevators, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention has relation to elevators, and is designed to lower cargoes from one point to another.

The main object of the invention is to'provide an elevator for lowering brick from kilns, wharves, &c., to the ground or into the holds of vessels automatically, thus facilitating the work and reducing the number of men required to perform the same.

Other objects and advantages of the invention will hereinafter appear, and be particularly pointed out in the claims.

Referring to the drawings, Figure 1 is a side elevation of an elevator constructedin accordance with my invention, the same being inpositi'on in a boat and adapted to receive its cargo from a wharf. Fig. 2 is a front elevation of the upper portion of the elevator,showing the means employed for governing the same, and Fig. 3 is a detail in section, hereinafter described.

Similar letters of reference indicate like parts in all the figures of the drawings.

As the invention is designed particularly for use in lowering brick from kilns, &c.,

(though it may be put to other uses,) I will proceed to describe it in connection with and as adapted for this purpose.

It-is well known that in removing brick from kilns men in gangs are stationed at dif-' ferent points-aloft, below, and midway therein-and the brick tossed from one to the other, thus passing along the line. Gangs are also employed in removing the brick after being deposited on the ground.

Referring moreparticularly to Fig. 1, A

represents a boat in which the brick are to be lowered, and B a wharf, the two being con nected and made accessible by an ordinary gang-plank.

0 represents the frame-work of the elevator,

50 and it comprises uprights 0, connected by suitable tie-bars O formin arectan ular frame, the lower ends of said uprights being provided with suitable casters, 0 whereby the frame may be transported to convenient points. ranged and forming guides, are the elevatorbeams D, which are of suitable height and connected at their top by means of a connecting-beam, D. (See Fig. 2.)

Interposed between the guiding-beams D is the elevator car or platform D which is provided with oppositely-arranged guiding-arms D at each side, which are adapted to embrace the guiding-beams D. At the upper ends of the arms B is secured a yoke, D, by which the elevator-car is suspendedfit (said yoke) being connected to a cable or rope, D, passing over and around pulleys D D, the latter rigidly mounted on a shaft, D, having bearings in lugs D and having at its outer end brake-wheel D. At the opposite end of the cable or rope D is secured a counterbalance or weight, D, which is sufficient to more than counterbalance the weight of the elevator. A brake strap or clutch, D connected to the beam D, as at D, passes over the brake wheel D and is connected to a lever, D", pivoted, as at D, to the beam D, and having a brake-cord, D, extending down to within a short distance of the base-of the elevator, and provided with a weight, D, said weight be ing sufficient to draw upon the lever D and strap D toprevent the brake-wheel from revolving, and it, being rigid with the shaft D, prevents the rotation and consequent movement of the elevator-car. In this manner the elevator car or platform is maintained at any desired point, and it may be stopped at any desired point by simply allowing the Weight to hang and exert its influence upon the brake-wheel.

The operation of lowering brick by my invention is as follows: A wheelbarrow containing a certain number of brick is placed upon the platform, and the man stationed at the 95 bottom of the elevator raises or prevents the weight D from drawing upon the lever. The weight of the brick and car being sufficient to overcome the weight D, the car will be lowered, subject, however, to government by IOU means of the brake, inasmuch as, if the weight is at any time allowed to exert its influence Midway the posts 0, oppositely ar- 0 upon the brake-lever, the car is brought to a standstill. Vhen the car arrives at its destination, the load of brick is removed and an empty wheelbarrow takes its place, the brake- 5 man raises the rod D", thus releasing the brake, and the weight D lowers, raising the elevatoncar, when the empty wheelbarrow is replaced. by aloaded one and the operation repeated. In this way it will be seen that a small number of men at the top of the kiln anda like number at the bottom or base of the elevator and a man at the brake are sufficient to do the work which required several gangs.

In some instanecs-as when loading a car or 15 boat or when the pile of brick becomes too high to be reached conveniently from the ground--it is found necessary to provide a platform or stop. For this purpose I provide brackets E, formed with clamping-arms ,E adapted to clamp the tiebars, and supporting-arms IE adapted to receive a platform or stop, E", against which the weight D is adapted to come, whereby the elevator-carriage is held at a higher elevation than if the weight were 2 allowed to fall to its lowest position.

Having described my invention and its operation, what I claim is- 1. In combination with the frame 0, having the tie-bars 0 the brackets ll, comprising the hook ends E, the supporting ends E, and the 30 Y stop E, substantially as specified.

2. The beam D, having the pulley D, bearings D shaft D, mounted therein, the pulley D and. brake-pulley D mounted on said shaft, in combination with the frame 0, guides 5 D, rope D, and car D the weights D 1), lever D",and band D,substantially as specified.

3. The combination, with the guides D, beams D, tie-bars C and uprights O, of the elevator-car D rope D, weight D, stop E, 0 and its support, substantially as specified.

In testimony whereof I affix my signature in presence of two witnesses.

ANDREW G. NEWTON.
