SPECIFICATION forming part of Letters Patent No. 618,810, dated. January 31,

Application filed February 18, 1898. Serial No. 670,745. (No model.)

To (0% whom it may concern:

Be it known that 1, WILLIAM B. WooD, a citizen of the United States, residing at Baltimore, in the State of Maryland, have invented certain new and useful Improvements in Toy Houses and Elevators, of which the following is a specification.

This invention relates to a toy house and elevator for the amusement of children.

The object of the invention is to provide a structure representing a house with a number of floors and an elevator of novel construction that is'operative to move up and down through all the floors.

The invention is illustrated in the accompanying drawings, in which- Figure 1 is a front elevation of the toy house, A showing the floors and elevator. Fig. 2 is a vertical section on the line 2 2 of Fig. 1 and shows the elevator mechanism. Fig. 3 is a rear elevation of part of the toy house, in which the rear wall that incloses the elevator mechanism is broken away.

The letter A designatesv the side walls of the house; I), the floors; 0, doors which open into the attic under the roof and where some of the elevator mechanism is located, and d the open shaft or vertical passage extending up and down through all the floors.

The front of the house is open or Without any wall.

The elevatorcage E is movable up and down the vertical shaft (Z and is attached to a cord which passes over a pulley h in the attic and then over a spool t' and down into an inclosed vertical chamber or passage j at the rear, where it is secured to a windlass 75, whose crank 71". is on the exterior. When the crank is turned, the cord g will be wound on the windlass and the cage F will be raised.

A novel mechanism is employed to retain the cage at any desired point of elevation and also to lower the cage. This comprises a brake strap or band Z, one end of which is made fast at Z to the Wall of the shaft adjacent the windlass. This strap winds once around the windlass 7t, and the other or lower end of the strap has a weight m attached. The surface of the windlass where the strap winds is made rough by sand, which adheres by an application of a solution of glue. A cord at is attached to the lower end of the strap 1 below the windlass and extends upward and is attached to a lever 0 in the attic.

Another cord n is attached to the opposite end of the said lever and passes downward through all the floors and at its lower end has a ring 19 attached.

It will now be understood that the weight on normally draws on the brake-strap land tightens its wound part around the rough surface on the windlass, and thereby causes it to hold the latter from unwinding, and thus retain the cage at any point of elevation. When the elevator is up and it is desired to lower it more or less, this may be effected by pulling on the cord n, which will tilt the lever and lift the Weight, and thereby slacken or loosen the Wound part of the strap around the windlass, and consequently the cage F will lower.

The mechanism is all inclosed and out of sight in the finished toy house.

The raising and lowering of the elevatorcage affords amusement.

Having thus described my invention, what I claim is 1. A toy elevator comprising a cage movable up and down; a windlass and a cord connecting from the windlass to the cage for raising and lowering the cage; a strap the upper end of which is held stationary; the middle portion of which is wound around the said windlass and the lower free end of which has a weight which normally tightens the said 85 j, inclosed in the walls of the house; a windlass in said passage and a cord connected from the Windlass to the cage for raising and connected with the other end of the said lever, as set forth.

IO In testimony whereof I affix my signature lowering the cage; a brake which is normally in the presence of two Witnesses.

5 in constant contact with the said Windlass and is applied thereto by a weight; a lever in the upper part of the house having a connection with the weight; and a brake-releasing cord WILLIAM B. V0 OD.
