Title: Insert with expandable head for locking in non-counterbored bores and method for making the same.
IPC: F16B25/00
Filed: 1967-03-14
Abstract: 1,175,156. Screw sockets. ROSAN ENG. CORP. 14 March, 1967 [15 March, 1966], No. 11985/67. Heading F2H. [Also in Division B3] An insert having an integral expandable head for locking the same into a bore in a workpiece 23 comprises a cylindrical body 15 having an axially threaded bore 19 and a counterbore 18, external threads 20 on the body, which are of uniform crest and root diameters and have uniform pitch and thread form, locking means on the exterior of the body opposite the counterbore and internal driving means in the body for threading it into the workpiece. The insert is made by reducing the diameter of one end of the blank and then straight roll-knurling the reduced part, the final diameter over the tips of the knurl being equal to its original diameter. The body is then tapped and counterbored, and an hexagonal hole 25 is broached through the threads to receive a driving tool. The external thread 20 is ground along the full length of the insert, so that where it is interrupted by the knurling, pointed teeth are formed. After the insert has been screwed into the workpiece the wall surrounding the counterbore is expanded radially so that the pointed teeth are embedded in the workpiece. In a modification the hexagonal hole 25 is omitted and instead the counterbore is deepened at a smaller diameter and then serrated teeth 38 are formed in the smaller diameter part of the counterbore. The diameter over the tips of the serrated teeth is equal to the diameter of the upper part of the counterbore. Fig. 14 shows an insert of the modified type which has been expanded to grip the workpiece.

Title: Improvements in latches or locking latches for doors, windows and the like
IPC: E05B17/20
Filed: 1922-05-02
Abstract: 201,255. Lawrence, E. M. May 2, 1922. Latches, sliding; striking plates.-Door and like latches are provided with two or more parallel grooves on their bevelled surface to prevent them being forced back by the insertion of a gimlet or like instrument through the door into the crack between door and door-frame. In the form shown in Fig. 1, two parallel grooves 16 are cut close together across the bevel 15 of the bolt 14 and one of the grooves is in alignment with the crack 17 between the door 10 and door-frame 11 and between the latch-case 12 and striking plate 13. The striking plate 13 has a broad bevel 18 for bridging the grooves 16 when the door is slammed. In the form shown in Fig. 4, the groove 118 across the ends of ribs 19 is parallel to end grooves 116, 117 which it joins by longitudinal grooves 119, 120. This arrangement gives the same security against forcing back the latch by a gimlet as in the previous modification, while it enables ribs 20, 19, to form a continuous bevel across the face of the latch with respect to the striking plate, which can therefore be made with a sharp edge instead of the broad edge 18. In the form shown in Figs. 5 and 6, the bevelled face of the latch is hollowed out, leaving side ribs 22 with notches 30. For further security against forcing back the latch, the hollowed-out part contains a catch 24, flanges 25 of which fit on the shanks 26 of the latch-bolt and are pressed upon by the latch spring 27 so that the catch 24 is aligned with the bevelled ribs 22. If a gimlet presses on the face of the catch 24, it moves downwards forcing a pin 28 carried by it through a hole 29 in the base of the latch so that when the latch recedes a short distance under the pressure of the gimlet. the stop-pin 28 engages the edge of the casing 12 and stops the latch from further movement. Two Provisional Specifications state that the latch bolt may be provided with a sliding member carrying the stop-pin and one Provisional Specification states that the stop-pin may be carried by a wedge-shaped member. Specifications 16139/96 and 139,262 are referred to.
