- a flat spring 57 identical to the spring 44 is mounted between key way plate 56 and end plate 58 which has central opening 81 through whichthe bolt 18 is guided. This plate, however, has no .key way slot so as to limit the rearward motion of the bolt 18 by virtue of the protruding pin 19.
- a shoulder 68 is formed on the bolt 18 to the right relative to FIG. 5 of the plate 58 and a biasing washer 69 rests against the shoulder 68.
- a guide tube 66 is mounted within the right end relative to FIG. 5 of the bolt supporting member 17 and is formed with a generally straight portion 66 which is aligned with the end 72 of the bolt which is received therein and a curved portion 67 formed adjacent the right end relative to FIG. 5 of the member 17.
- Frame members 61 and 63 are formed with openings through which the tube member 66 extends and support the tube 66 relative to the member 17.
- the member 63 is shown, for example, in FIG. 3 and is welded by weld bead 64 to the wall of the member 17 as shown.
- a spacer member 62 is mounted between the member 63 and the member 61 and a spacer member 59 is mounted between the member 58 and the member 61.
- a drifting washer 90 is slidably mounted on the tube 66 and a first spring 71 which might be constructed of stainless steel is mounted between the member 69 and the drifting washer 90.
- a second spring 70 which may be made of stainless steel, is mounted between the drifting washer 90 and the support 61.
- a key receiving'opening 73 is formed in the inner end of the bolt 18 within the tube 66 and has the outer portion tapered as shown at 72 so as to guide the key into the opening 73.
- Opening 73 has an inside diameter slightly larger than the maximum thread diameter of the key head 22. The opening serves to guide the key head 22 into axial alignment with threads 74 of bolt 18.
- An inner portion of the opening 73 is threaded with threads 74.
- a central pin 75 is mounted in the bolt 18 and extends throuugh the threaded portion 74 and into the opening 73. The purpose of the pin 75 is to prevent the unauthorized party from entering, using a common bolt not having a mating hole drilled therein.
- the key is shown in FIG. 6 and comprises a key head 22 which has a threaded portion 24 with threads which mate with the threads 74of the bolt.
