SPECIFICATION forming part of LettersP at ent No. 382,487, dated May a, 1888.

Application filed January 27, less. Serial No. 262,124. (:70 model.)

To all whom it may. concern-.-

Be it known that I, GEORGE A. MOORE, of

Cambridge, county of Middl'esex, and State of drawings representing like parts.

Many elevators in use in hotels and other public places are and have to be adapted for both passengers and freight.

In this class of elevators as now made the freight-platform is fixed to the passenger-car at a distance from its bottom or floor, and the elevator-well is excavated below the lowest passenger-landing'for a depth equal to thedistance of the freight-platform below the passenger car or floor; or, in other words, the freightplatform, connected rigidly to the car-body and occupying. a fixed .position with relation to the car-body and at a distance below the car-floor equal to nearly the height of the passenger-car, entersa pit at the bottom of the elevator-well. The formation of a pit at the bottom of the elevator-well for the reception of the attached freight-platform is sometimes very difficult, owing to the nature of the soil, and is at the same time more or less expensive. Insome instances the basement-story of the hotel or other building is utilized as part of the elevator-well, and in this case, with elevators as now constructed, the said basementstory is not accessible from the passenger-car.

In my experiment, to avoid making the pit and at'the same time to enable the basement story to be accessible to passengers in the passengercar, and so,'also, to avoid the usual unsightly freight-platform dependent from the passenger-car, I have combined with the passenger-car an extensiblefreight car or platform which,when it is desired to carry freight, may be quickly brought into position to be used as a freightycar or platform, the said freight car or platform when not to be used being brought close up to the floor of the pas senger-car, as will be described.

My invention consists, essentially, in the combination, with a passenger-car, of an extensible auxiliary freight car or-platform which at will may be brought in position to be used as a freight-car.

Other features of my invention will be pointed out in the claims at the end of this specification, L

Figure 1 is a vertical section through'the ele'vator-shaf t and passenger-car, the said drawing by full lines showing the auxiliary flor freight car in the position occupied by it when not in use, and by dotted lines the position when in use, the lines of section being shown in Fig. 2; Fig. 2, a section of Fig. -1 on line a:

The passenger car or cage a, located in the shaft or well a of a building, may be ofordinary'or well known construction, it :being adapted to be raised and lowered in-the;said shaft or well in any Well-known or usual man-l ner. The passenger car or cage (1 has extensibly attached to it below its bottom or floor a an auxiliary car 01'' platform, a which: in the ordinary use of the elevator will be em ployed asa freight car or platform.

The auxiliary car or platform at may befex tensibl y attached toithe passen gercar, as herei 11 shown, 'by means of rods a", one end of each rod being'secured to the auxiliary car or platform, preferably near the corners of the same, and the other end of the said rod extended up through the floor aof the passenger-car and into a tube or i e a secured asshown to a base, a, attached to the car-floor.

Each rod a at its extremity within the tube is herein shown as screw-threaded to .be

engaged bya threaded collar, 12, provided with Q a packing, b, between the said collar and the interior of the tube, the said rod'at its end also having-a cap, b fitted-thereon. I

The tube or pipe, as herein shown, has screwed upon its ppper end a sleeve or extene sion, b towhich is fastened a clamp consist.- ing of two arms, b If, pivoted, as atb, tothe said extension. provided, as sh'own,with a semicircular recess, which enables the arms to encircle the rod a* when the said arms are fastened together by Each arm of the clamp is a pin, 6, or otherwise, the said arms cncircling the rod below the cap I), as shown in Fig. 3, thereby preventing the downward movement of the rod within the tube or pipe a and thus holding the auxiliary car or platform in its elevated or full-line position immediately below the door of the passenger-car.

Each tube or pipe a as shown, is sustained at its upper end by a bracket, a, secured to the sides of the car. Each rod a, below the car-floor,is preferably providedwith an auxiliary clamping device, shown as a set-screw,c, extended through a boss or collar, 0 secured to the car-floor.

In operation let it be supposed that the auxil ary car occupies the position shown by full lines, it being preferably concealed from view by a panel, a, secured to the passengercar. \Vith the auxiliary car or platform in the position shown, the passenger-car may be used lIl usual manner to carry passengers. If it IS desired to use the auxiliary car or platform for transportation of freight-such as trunks, &c.from one floor to another of a buildlng, the operator, through the shipperrope or other usual operating mechanism, (not shown,) raises the car a sufficient distance to enable him to loosen the set screws 0 or other clamping device on the rods a, and he then releases the clamping-arms b b at thetop of the tubes or pipes a", and if the car is at the bottom or ground floor the operator starts the operating mechanism to raise the passengercar, while the auxiliary car or platform remains stationary. As the passengercar rises, each tube or pipe travels up over its rod a until the base a strikes against the collar b, and when this occurs the operator stops the movement of the passenger-car. If it is desired to use the auxiliary car or platform when the passenger-car is at or near the upper floors of the building, the operator unclamps the rods, as described, thus permitting the auxiliary car to descend by gravity until the collar 6 strikes the base a.

The clampingarms b b at the top of the tubes may be operated singly or in pairs, they being connected substantially as shown in Fig. 6, wherein the arms I) b on opposite sides of the cara are joined by links 40 to a rod, 41, herein shown as extended through a suitable bracket, 42, the said rod being clamped in any desired position by screw 43; or all four clamps may be operated at once. If desired, the auxiliary car may be locked to the passenger-car by latches d d, as shown in Fig. 7, the said latches being adapted to pass through slots (1 in the auxiliary car and to be operated to unlock the said auxiliary car by a lever, as d, extended into the passenger-car, the said lever being connected to a rod, d, joining the said latches.

As shown in Figs. 3 and 4, the rod 0, is made smooth or p1ain,so as to slide within in the base a", or it may be in the tube itself,

the rod a in such event being free to rotate.

The tubes at are herein shown as located inside the passenger-car; but, if desired, it is evident that the same may be located outside thereof.

I prefer to employ the means shown for guiding and securing the auxiliary 'car or platform to the passenger-car; but I do not desire to limit my invention to the particu lar mechanism shown, as the said auxiliary car may be raised toward and lowered from the passenger-car in many obvious ways-such, for instance, as by racks and pinions.

In practice the auxiliary car or platform will be guided in the shaft or well bythe same guides as the passenger-car.

The tubes or pipes a are shown as extended up into the passenger-car a considerable distance,and the rods a, extended into said tubes, are made in one piece; but it is evident that the tubes a may be made considerably shorter and the rods a made in sections, so as to telescope within the said short tube, and when this construction is used the said tubes may b located beneath the seats. I t

I claim- 1. In an elevator, a passenger-car combined with an auxiliary car or platform extensibly connected thereto, substantially as described.

2. In an elevator, a passenger-car, tubes or pipes, as a secured thereto,combined with an auxiliary car or platform located below the said passenger-car and provided with rods to enter the said tubes or pipes, and with a clamping device to secure the said rods and lock the auxiliary car in its elevated position in proximity to the passenger-car, substantially as described.

3. In anelevator, a passengercar provided with a panel, as 0, combined with an auxiliary car, or platform extensibly connected to the passenger-car and adapted to be concealed in its elevated position by the said panel, substantially as described.

4. In an elevator, a passenger-car, tubes or pipes secured thereto, and an auxiliary car or platform located below. the said passenger-car and provided with rods a to enter the said tubes or pipes, combined with a clamping de vice at or near the top of the said tubes to secure the said rods, and with a second or auxiliary clamping device located below the passenger-car floor,substautially as described.

In testimony whereof I have signed my name to this specification in the presence oftwo subscribing witnesses.
