Title: Improvements in or relating to door lock structures
IPC: E05B65/32
Filed: 1947-08-12
Abstract: 633,018. Door latches. HOUDAILLE-HERSHEY CORPORATION. Aug. 12, 1947, No. 22365. Convention date, Sept. 27, 1946. [Class 44] In a door latch the outside handle operates a lever 11, Fig. 1, adapted to contact and rotate a second lever 16 to release the bolt, the second lever 16 being movable by a number of different methods to a position in which it cannot be contacted by the lever 11 thus rendering the outside handle ineffective. The latch 26 is carried on a pivoted plate 24 which in the locked position also supports the free end 51 of a serrated lever 49, Fig. 2, co-operating with an arm 45 adapted to retain a rotor bolt 39, Fig. 5, in an angular position to engage the keeper K, the position of engagement depending on the force with which the door is slammed. In a normal unlatching operation the lever 11 contacts a projection 17 on the second lever 16 to rotate it in an anticlockwise direction, the nose 25 contacting an arm 24a on the plate 24, rotating it in a clockwise direction to lift the latch 26 and release the arm 45 retaining the rotor bolt. An inside handle 62 is connected through an arm 102 and a link 20 to turn the lever 16 in an anti-clockwise direction to release the latch or in a clockwise direction to render the outside handle ineffective by disposing the projection 17 out of the path of the lever 11. The inside handle-62 is provided with a centring spring 104 to return the handle to the normal position, the lost motion in a pin and slot connection to the lever 16 ensuring that the centring movement is not transmitted to the lever 16. A push rod 65 operated by a button on the inside of the door may be depressed to rotate the lever 16 in a clockwise direction and this mechanism may be used to lock the door from the outside by closing the door with the outside handle turned and then releasing the handle. Rotation of the outside handle when the lever 16 is in the locking position places the lever 11 behind the projection 17. The lever 16 is returned to the unlocking position as the door closes by the engagement between the latch 26 and the keeper. When the outside handle is released after the door is closed, the spring 14 on the lever 11 again moves the lever 16 to the locking position in which the outside handle is ineffective. A key operated lever 29 has arms 31, 32 embracing a projection 21 whereby the lever 16 may be moved to and from the locking position from the outside. This lever is retained in either position by a spring 34b engaging in one of two notches 36, 37 and thus serves to retain the lever 16 in the locking or unlocking position.

Title: Improvements in flexible pocket receptacles
IPC: A45C1/02
Filed: 1926-09-13
Abstract: 258,581. Buxton, W. R. Sept. 16, 1925, [Convention date]. Pouches; purses. - Relates to a flexible folding pocket receptacle of leather &c., one part of which forms a pocket or pouch for coins, tobacco, &c., the other part when the receptacle is in the opened position forming a tray. portion closed in at the edges. Fig. 2 shows a receptacle formed from the blank shown in Fig. 1, the meeting edges 26 being sewn together and the parts 28 then secured by adhesive to the upper face. The creases 22, 23, 24 enable the side walls to rise, lifting with them the end wall 33 of the tray portion 31, on pressure being applied to the sides at the ends of the central fold line 34 dividing the pouch portion 30 from the tray, Fig. 6. When the pressure is released, in the case of the construction shown, the receptacle springs back to its original shape; by modifying the disposition of the creases, however, the receptacle can be arranged so as to retain the distorted shape, as may be required in a tobacco pouch, until pressure is applied to the upper and lower surfaces to release it. Instead of being made from a single creased blank the receptacle may be formed from the parts shown in Figs. 9, 10, and 11, the part 44, an additional lower part, providing a compartment for notes and being attached by parts 45, 46 to the upper face of the receptacle proper, the ends of which are left open. Reinforcing pieces 42, 41 are provided to stiffen the material and so permit the unreinforced material of the sides and ends to fold in the manner provided for by the creases or scorings present in the form first described. The tab 36<1> carrying one element of the fastener may, as shown, be formed on the loose reinforcing member 41 and passed through a slot in the end of the pocket portion, instead of being fixedly attached as in Fig. 2. The part 41 may serve also as a partition for the pocket portion, Fig. 12, the folding flap portion 43 being turned outwardly to gain access to cards &c. placed above the partition.

Title: Improvements in or relating to the construction of concrete piles or foundation elements
IPC: E02D5/46
Filed: 1924-09-25
Abstract: 244,838. Neelands, A. R., and Damry, G. Sept. 25, 1924. Piles. - A method of making concrete piles, especially applicable in loose, soft or waterlogged ground, consists in forming a bore hole, fitting it with a temporary lining tube, ramming ballast, gravel, &c. into the ground while lifting the tube, and injecting liquid cement or the like into the mass of ballast or gravel. The casing tube 5, Fig. 1, is first sunk into the bore hole as far as the solid rock 4. Four perforated tubes 7 are then placed vertically in the hole, ballast is dropped in and rammed by a ram 8, Fig. 5, sliding on the tubes 7. The ram is lifted out at intervals to permit the introduction of more ballast, and the tube 5 is intermittently or continuously lifted during the ramming. The ballast is thus caused to spread in the loose or waterlogged strata 3. In order to retain the tubes 7 at the correct distance apart, ties 13 are threaded over the tubes 7 and dropped at intervals. When the bore hole is filled to the ground level the tubes 7 are coupled to a pumping or grouting plant and liquid cement is forced into the ballast and into the surrounding strata. The tubes 7 also serve as reinforcement to the completed pile.
