To all whom it may concern:

Be it known that I, REUBEN HALLENsrErN, merchant, of Melbourne, in the Colony of Victoria, have invented certain new and useful Improved Appliances for Operating Sliding Doors Closing Lift or Stairway Openings in Floors of Buildings, (patented in Great Britain October 1, 1890, No. 15,541; in Belgium October 1, 1890, No. 92,171; in Austria-I-Iungary February 12, 1891, No. l14,193 and No. 77,829; in Turkey October 1, 1890, No. 196; in .France October 1, 1890, No. 208,578; in Italy November 13, 1890, Vol. LVI, 82; in Spain November 15, 1890, No. 11,291; in Bra- Zil December 16, 1890, No.' 1,018, and in Cape of Good Hope February 11, 1891, folio 666,) of which the following is a specification.

This invention is specially adapted for 'opening and closing simultaneously lift or stairway openings in lofty buildings 'by means of sliding doors. This is effected by means of a vertical shaft placed parallel to but outside the lift or stairway and running from the top to the bottom of the building. The shaft is provided on each floor with a hand-wheel, by means of which the shaft may be rotated from any floor. A bevel-pinion is keyed on the shaft belowT each floor. Each bevelpinion gears with a bevel-wheel on a transverse shaft below each floor, and by means of this transverse shaft motion is communicated to the connections, whereby the sliding doors are opened or closed.

In the accompanying drawings, Figure 1 is a sectional side elevation showing the apparatus as applied to alift-opening. Fig. 2 is a sectional front elevation of the same.

In Figs. 1 and 2, A is avertical hand-shaft continued from floor to floor throughout the height of the building.

B B are the hand-wheels, whereby the shaft A may be operated from any door.

C is a bevel-pinion keyed on the shaft A below each floor and gearing with the bevelwheel C', placed at the end of atrausverse shaft D, which is provided with lever-arms D D', to the extremities of which are articulated connecting-rods E E, the opposite ends of which are articulated to the under side of the sliding door F, that is supported on rollersf, running on guides f.

G G are the cage-guides, and H is the liftrope.

A The modus operandi is as follows: The attendant if he wishes to open or close the doors from any floor will turn the hand-wheel nearest to him, thereby rotating the vertical shaft A and communicating motion to the transverse shaft D through the bevel-gearing C C. This will cause the leverarnns D D to move in the arc indicated by dotted linesin Fig. 1, and as the lever-arms D D are connected by the connecting-rods E E to the sliding door F the latter is caused to slide in the required direction beneath the floor.

It is manifest that, instead of the lever-arms and connecting-rods, as above described, pinions on the transverse shaft gearing into racks on the under side of the sliding door maybe substituted.

Having thus described my invention, what I claim as new, and desire to secure by Let ters Patent of the United States, is-

In a device for operating sliding doors, the combination, with vertical shaft A, provided with hand-wheel B and pinion C on said shaft, of transverse shaft D, pinion C', mounted on one end thereby and engaging said pinion C, arms D', attached to said shaft D, and conmeeting-rods E E, attached at one end to arms D and at the other end articulated to the under side of the sliding door, substantially as set forth.

In witness whereof I have hereunto set my hand in presence of two witnesses.
