Abstract: 19,104. Stewart, J. B. M., and Stewart, W. R. Sept. 4. Fastenings for doors.-A means is provided for opening, from the outside, by means of a key without the use of a coin. Fig. 1 shows a back view of the upper part of one form, the lower part being used as a coin receptacle. A case 1 carries an internal plate 3 spaced from one face by blocks to hold the mechanism in position. The sides 15,16 of a coinshoot lead from the front and are arranged over the vertical slotted end 12, 13 of a bolt 10. The bolt 10 is operated by the knob spindle 20 and lever 18 from the outside only. The bolt 11, forming the latch bolt, is operated, from the inside, by knob spindle 31 and lever 29. The bolt 11 also carries a shoot slot formed by sides 24, 25, and is arranged so that in the shot position a stud 43 acts to retain the coin. Guard-plates 14, 26 on the bolts prevent the insertion of a coin when the bolts have been moved. An inserted coin acts to connect the two bolts so that they can be operated simultaneously. The slide 13 of the shoot on the bolt 10 is cut away so that on the release of the bolt 10 the coin can be discharged. An ordinary slide bolt 32, carrying an "engaged" " or " vacant " indicator, is mounted below the spindle 31, and is constructed to be withdrawn by a key inserted from the front through a keyhole 45 ; further motion of the key acting on the cam 46 can also withdraw the bolt 11. Bolts 10,11 are held forward by springs 21, 27. In a modified form the fixed shoot is omitted, and a vertically sliding frame plate, operated by a turn handle, is substituted for the sliding bolt. The frame plate can engage with a stud on the latch bolt, and is so constructed that the plate and latch bolt can be released by a key. The Provisional Specification describes a form of shoot in which the latch bolt has a vertical stud at the upper end of which is a lip instead of a slot.

Abstract: 21,684. Stewart, J. B. M. Oct. 6. Fraud, preventing.- Fig. 1 is a plan view of the coin-slot, Fig. 2 an inverted plan, and Fig. 4 a side view from the left of Fig. 1. The edges c, d of the slit b are curved and oppositely bevelled each side of the centre, and, beneath the edge having its bevels exposed, a bracket e is attached to the plate which has a similarly-shaped lip f, set towards a sloping plate g on the other side. Spring jaws h flank the plate e to nip the coin. In the event of the insertion of a plain disc, the lateral displacement afforded by the slight hollowness of coin not being obtainable, the lower point of the periphery of the disc, instead of passing between the edge of the lip f and plate g will come into contact with the lip, and its insertion will be prevented.
