Abstract: 441,848. Arc lamps. SPERRY GYROSCOPE CO., Inc., Manhattan Bridge Plaza, Brooklyn, New York, U.S.A.-(Assignees of House, F. R. ; 4, Hayes Street, Baldwin Harbor, New York, U.S.A.) June 26, 1934, No. 18838. Convention date, June 26, 1933. [Class 39 (i)] In an arc lamp the negative electrode of which is fed by a shaft rotated in the required direction by one of a pair of oppositely disposed ratchet wheels operated by pawls on a reciprocating carrier, the appropriate pawl'being put in action by a pivoted fork, which in its central position holds both pawls out of engagement, the pawls 99, 100 are so arranged in relation to the ratchets 101, 101<1> that the bulk of the stroke takes place on the same side of the axis as the pawl is situated. Fig. 5 shows this arrangement, P, P<1> being the stroke of the pawl when it is nearly out of engagement with the ratchet, and E the point where it engages when in fuller action. The carriage 95, Fig. 2, supporting the pawls 99, 100 is pivoted to a link 97 and actuated by a rocking lever 93 driven from a motor 46 by a worm 85, a friction clutch 86 and a crank. The fork 103 is pivoted at 106 and operated by an electromagnet 58 connected across the arc and acting against a spring 107 to put the appropriate pawl in action. The magnet 58 is in series with a resistance having a negative temperature - characteristic to eliminate the effects of temperature changes on the coil. The pawls 99, 100 engage ratchets 101, 101<1> on a shaft 102 connected to the negative electrode feed rollers. The magnet 58 receives current from the positive electrode through its feed rollers, so that when the electrode is worn so far as to lose contact with the rollers the negative electrode is rapidly retracted. The electrode can also be operated by hand by means of a head 108 which, in the position shown, rotates the shaft 102 through bevel gear 110 and holds the fork 103 in a position to put the pawls 99, 100 out of action by means of a slotted lever 111. The means for feeding the positive electrode are identical with those described in Specification 441,913 and the negative electrode holder and feed rollers with those described in Specification 441,914.

The piston rod 43 slides in a fluid tight manner through a fixed guide 45 provided with a leakage passage 49 between the tubes 5, 57, 1 and a delivery passage 47 which leads to the annular space 55. The rod 43 then assumes a decreased diameter 67 and passes through a packed spring-loaded valve 69 to the piston 79 reciprocating in the cylinder space 77 bounded by seating 73 of the valve 69 and an internally recessed screw plug 83 in the bottom of tube 5 near the oil drum bottom. The cylinder surrounded by a strainer 87 is provided with ports 85 and priming tubes 89 in such staggered relation that on the down ward stroke oil is forced to the cylinder head, whilst simultaneously oil is displaced from the space above the valve 69 to the annular space 55 by the increased diameter of the rod 43. On the upward stroke oil above. the piston 79 is forced past the valve 69 due to suction created below the guide member 45. Delivery may be regulated by means of a pressure responsive motor switch in pneumatic connection with the delivery pipe 63 by means of a conduit 95.

[Also in Division B7] In a sliding door assembly for a building wherein the door also moves transversely of the door opening during opening and closing movements, the door 21, Figs. 1 and 2, is supported at one vertical edge, which trails during opening of the door, by a pillar 13 slidable along the top of the bottom sill plate 12 of the door opening, the door being connected to the member 13 by Z-hinges 25 of which the intermediate leaves are rigidly connected by a plate 26, the door also being provided with a rigid bracket 30 having a roller 31 engageable in a channel guide 32 secured to the bottom 10 of the vehicle and rollers 33 carried in a pivoted frame 35 on the other vertical side edge of the door, which rollers engage a T-shaped guide rail 34 on the side 11 of the vehicle and on the reveal 37 of the door opening. The member 13 of inverted T-shape comprises an upright portion 15, to which are secured the inner leaves of the hinges 25, and a horizontal member 16 slidably connected through a channel guide 17 and rollers 19 with the inner face of the bottom sill. The member 13 also carries a roller 14 engaging the plate 12 and a flange 20 which engages under the plate to prevent tilting of the member 13. When the door is initially moved from the closed position it pivots about the outer hinge pins (as seen dotted in Fig. 1) whilst the rollers 33 move along the guide rail 34 within the reveal 37 to the outer corner of the door opening. The door is then slid to the right in Fig. 1 and the roller 31 in the guide 32 causes the hinges to open and move the door outwardly of the opening. The portion 15 of the member 13 has dowels 22, 23 which engage respectively in holes 24 in the opposite vertical edges of the door opening in the closed and open positions of the door, the latter being provided with a "slam" lock. In another embodiment the rollers 33 are replaced by a double-hinged plate assembly provided with rollers engageable in a trackway formed on the inner face of the door. In a further embodiment described with reference to Figs. 5 and 6 (not shown) the pillar 13 is formed by a shaft having a lower cranked portion pivoted in a quadrant-shaped platform slidable along the channel guide 17 and having a roller engaging a rebate of the bottom sill. The shaft is pivoted on the edge of the door which trails during opening. An extension of the crank carries a roller engaging in a guide in the bottom of the vehicle. The crank connected to the shaft carries a small roller engaging the top of the platform and the edge of the door which leads during opening is connected, through a pivoted arm and rollers, with a guide on the vehicle side. When the door is in the closed position the pivoted shaft may be secured from movement out of the door opening whereby the door can be opened in conventional manner by merely swinging about the shaft.

The head of the bolt 9 may also be provided with a peripheral lip 11 and a reduced diameter for the same purpose. The joint is assembled by placing the bush 2 on the bolt 1, passing both through the cheeks 3 and 6 of the yoke 4, placing the washer 8 on the bolt and then holding the assemblage together by the nut 10. The axial length of the bush 2 is preferably slightly greater than, and the axial length of the eye 5 slightly less than, the width between the cheeks of the yoke so that when the nut 10 is tightened up ridges 5a are produced to locate the eye in the yoke. To prevent rotation of the bolt and washer during tightening up, the bolt head 9 and washer 8 are provided with flats 12 which co-operate 'with projections 13 on the cheeks of the yoke. The ends of the bush 2 may be reinforced with fabric to prevent spreading when under pressure. In a modification, the smaller diameter portions of the bolt head 9 and washer 8 may be lengthened axially so that they project beyond the opposed faces of the yoke.
