outer and inner wall portions thereof of a means for bonding them together, such means comprising a thin sheet-metal member the ends of which where embedded in the cement are bent at right angles to the portion which extends between the walls and are provided with a curved or irregular outline. (3.) In a cement building-block, the combination with outer and inner wall portions of cement or concrete of a sheet-metal bonding member between them, the ends of which where embedded in the cement are bent at right angles to the mid-portion and are pierced with an aperture or apertures. (4.) In a cement building-block, the combination with outer and inner wall portions forming a corner of sheet-metal bonding members between them, means for connecting the corner bond members, such means comprising an aperture in the space portion of one bond and outwardly bent fangs cut in the bent end of the other corner bond, which projections may be entered and clinched through the aperture referred to.

No. 22300.—8th January, 1907.—CHARLES ERNEST MUGGERIDGE, of Ridge Hall, Chapel-en-le-Frith, Derbyshire, England, Director of the joint applicant company named hereinafter, and the VAN KANNEL REVOLVING DOOR COMPANY, LIMITED, of 27 Great James Street, Bedford Row, London, England. Improvements in door structures.

Extract from Specification.—According to one part of our said invention we provide a doorway having the opposite sides in the form of an arc or segment of a circle or polygon. The door is preferably composed of a series of radial wings rigidly united in pairs, the pairs of wings being adjustably united at a central junction-line so as to permit of fixing them in planes either parallel or at any required angle with respect to each other. The door structure is suspended from an overhead surface, ceiling, or roof by means of a rotating support, and this rotating support is located on a wheeled carriage moving on a track arranged transverse the doorway. The rotating support or pivot depends through a slot or passage in the roof or ceiling, and there is a hinged cover for the slot operated by a projection from the carriage. Stops are provided to catch and hold the carriage at the limit of its movement. The contact surface or edge of each radial wing is provided with a fixed strip of flexible, yielding material like rubber cloth, and this strip is fixed at an angle with respect to the plane of the wing in such manner that the door moves freely when rotated in one direction only, while the rubber strip impinges against the walls of the doorway and operates to resist rotation when attempt is made to rotate the structure in the opposite direction. We provide novel and useful devices for locking the doors together and bracing them; also for locking pairs of wings together and to a fixed point in certain instances; also for limiting the movement of pairs of wings under the influence of a retracting device when it is desirable to ventilate the interior while the door is in position and in use. We also provide a non-rotating steadying pin or pivot which is longitudinally movable with means for holding said pin against displacement.

No. 22334.—23rd January, 1907.—THOMAS WHITEHORN, of 19 Munro Street, Coburg, Victoria, Australia, Mechanic. Improved apparatus for packing predetermined quantities in bags.*

Extract from Specification.—The apparatus is worked in the following manner: Assuming the right-hand cylinder is just receiving the weighed substance, the plunger thereof will be in its raised position and the other plunger lowered, and both will be stationary on account of the clutch being out of gear. At this time the leg of the other cylinder is closed by the hinged door, and the bag of the right-hand cylinder will be raised up by the table. When the cylinder is full the treadle is operated and the plunger descends, thus compressing the substance into the bag and at the same time forcing both the latter and the table down until at the limit of the movement the clutch automatically throws the plungers out of gear. Furthermore, by this movement the lever of the door is operated and causes the latter to swing over, thus opening the leg of the left-hand cylinder. During the descent of the right-hand plunger another bag is slipped up over the left-hand cylinder by means of the bag-opening device, and the table thereunder is raised by releasing the pawl. Thus, whilst a bag is being packed by one plunger, the other is being placed in position for a similar operation by the other plunger, and the operation is almost continuous. When this packing apparatus is used in conjunction with a weighing-machine a warning bell is automatically rung on the latter, when the weighed substance is discharged therefrom into the cylinders so as to apprise the packing-operator of the right time to throw the clutch into gear to operate the plungers.

No. 22493.—25th February, 1907.—FREDERICK WILLIAM GIFFORD, Judge, and WARD CARDEN GIFFORD, Engineer, both of 940 New York Life Building, Kansas City, Missouri, United States of America. Improvements in apparatus for producing the illusion of travelling in a railroad-car or the like.

Extract from Specification.—Figs. 1 to 3 are a partial side view, cross-section, and detail view, showing certain improvements in the car and in means for rocking and causing same to bump on stopping. The car 1 is provided with a dummy vestibule end 2, with platform 3 and steps 4 to give the illusion of entering an actual railway-car. The car is mounted by providing same with a suitable number of supports 12, having spherical portion 13 engaging a bearing-plate 14, mounted on runners 15, carried by the supporting-frame 16. The car is rocked by means of a chain or equivalent 5 connected at its ends to opposite sides of the car as by hooks 6, and passing over a sprocket-wheel 7. Another sprocket-wheel 11 is mounted on the axle of the wheel 7, and round said latter wheel passes a second chain 8 guided by pulleys 9, and passing around a hand-operated chain-wheel 10 within the car. Stops 25, which may be cushioned in any suitable manner, are provided for limiting the extent to which the car may be rocked in either direction. For the purpose of causing the car to bump in imitation of the usual jerk in stopping a train, the bearing 14 is slidable on the runners 15, the latter being provided with abutments 17 at each end. The bearing 14 is provided below with a rack 18 meshing with a pinion 19, mounted on transverse shaft 20, adapted to be rotated by a chain 21 outside the car, the chain passing over a wheel 22 having a handle 23 extending through a segmental slot 24 in the car-wall to within the car to be operated by the attendant. By placing the chain 21 outside the car as shown, and giving the handle sufficient play in the slot 24, the chain is not strained when the car is rocked, as described.
