Abstract: 138,351. Servidor Co., (Assignees of Matchette, F. J.). June 12, 1914, [Convention date]. Hotel indicators.-A cabinet &c. is provided in the wall or door of the room of a hotel &c. which communicates by doors with the in. terior and exterior for the transmission of articles without the entrance of a servant. The invention is shown applied to a door, there being two cabinets closed by doors 32, 36 on the hall side, Fig. 2, and similar doors on the room side. The door 32 is opened by a key. Signalling disks showing through apertures 34 indicate to the servant or guest the placing of articles on the coat-hanger 60 or platform 66. The hanger and platform are connected by rods and links 71 to spring-controlled bell-cranks 70 which operate a spindle 75 by links 74 as shown in Figs. 3 and 4. Levers 91, 91<1>, on the spindle 75 having downturned bevelled ends engage blade springs 89, 89' attached to the disks 80, 81, which are pivoted to the doors and spring controlled so that the legend inscribed thereon is held away from the aperture 34. When the guest deposits an article in the cabinet and actuates the spindle 75, the disk 80 on the hall side indicates his requirements, but the disk on the room side is freed from engagement by the opening of his door. When the servant removes the article, the bevelled end of the lever 91 rides over the spring 89 without moving the disk, but on returning the article the disk is actuated and the guest warned thereby. The lower compartment is only used for transferring articles into the room and a signalling disk is provided only on the room side on a spindle 101 with counterpoise 103 and is operated when the servant opens the door 36, Fig. 10, by a shaped bracket 104 which engages a rod 107 on the spindle and throws the counterweight and disk over the central position. When the guest opens the room door, the spindle and disk are returned to normal position by a bracket 105 which engages an edge of the disk. A stop 108 limits the movement of the disk in both directions. To announce the desire for service to a central point, a pair of electric contacts 180, 181 are made to close a circuit by an arm 182 on the disk 80 when the guest uses the compartment.
