Doon LOCK. l
Application filed October 21192'5.' Serial-N0. 63,937.
The object of this invention is to provide a novel lock which' will operate without springs, and a locksmith, working within the scope of what is claimed, can make Vchanges in the vprecise structure shown,
retracted; Figure 4 is a section on the line 4-4 of Figure 3; Figure 5 is a sectional de tail which shows certain parts as they will appearV when the bolt has been shot; Figure 6 is a section on the line 6-6 ot Figure 1; Figure 7 is a section on the line 7-7 ot Figure 2; Figure 8 is a. plan of the barrel; Figure 9 is an elevation ot the barrel.
The lock includes a casing 1. There is keyhole slot 41 (Figure 7 in the casing 1. At one end, the casing 1 has an opening 2 The casing 1 is provided with a transverse internal guide 3. A bolt 4 slides in the opening 2 and in the guide 3. The bolt 4 has a circular opening There are seats 6 in the upper edge of the bolt 4. A link 7 extends along one side of the bolt 4. The guide 3 is cut-away, as at 8, to receive the link. The link 7 is pivoted at 9 to the bolt 4 to swing parallel to the'bolt. The bolt 4 has right-line sliding movement in the opening 2 and in the guide 3. At its inner1 end,
the link 7 is supplied with a circular opening 10. There is a seat 11 inthe lower edge of the bolt 4 below the inner end of the link 7.
A keeper block 12, of considerable weight, slides between the bolt 4 and one side wall of the casing 1 in a direction at right angles to the direction in which the bolt 4 slides. The keeper 12 is constrained to a right-line movement, because it has elongated slots 14 receiving pins 15 on the ing 1.l Inwardly extended projections 16 on the keeper12 overhang the bolt 4. When the bolt is shot, the projections 16 are received in the seats 6 of' the bolt. A circular opening 17 extends part-way through the keeper 12. A thinned ward 18 projects from the keeper 12 into the opening 17.
The numeral 2() marks a latch mounted to swing parallel to the keeper 12. One end of the latch 2O is pivoted at 22 to the lower end of the keeper 12. Near its opposite end, the latch 2O has an upstanding finger 21.
-The finger 21 is adapted to be received in Ethe seat 1i of the bolt 4, when the bolt is advanced. The latch 20 tilts on a fulcrumV .piece 23 carried by the bottom of the casing' l. z The lock includes a barrel 24 detailed in Figures 8 and 9. The barrel 24 is provided Vwith a longitudinal keyhole slot 25. The
.Theends 26 of the barrel 24 are journaled Y A first in the side walls of the casing 1; eccentric 27 on the barrel 24 is received in the opening 10 of the link 7. The barrel 24 is supplied with a second eccentric 28. f This eccentric operates in the opening 17 ofthe keeper 12. There is a cross groove` 29 in the barrel 24'. The cross groove 29 receives the ward 18 on the keeper. 12 when the barrel 24 is' rotated.
The numeral 30 marks a Ykey having a' notch 31, a stop shoulder` 32, and a beveled end 33.
lhen the bolt 4 is retracted, as in Figure 1, the keeper 12 is supported in raised position by the second eccentric 28 on the barrel 24. The projections 16 are out oit engagement with the seats 6 of the bolt 4. The latch 21 is in the position of Figure 1, tilted Vdownwardly toward its free end on the fulcrum piece 23,'with the finger 21 of the latch out of engagement with the seat 11in the bolt 4. The key 30 is inserted into the slot 41 of the casing 1 and into the slot 25 of the barrel 24. The barrel 24 is rotated, and as it is rotated, the eccentric 27 on the barrel, cooperating with the link 7 advances the bolt 4. lhen the barrel 24 isrotated, the second eccentric 28 on the barrel moves around to the lower part of the opening 17 in the keeper 12. This permits the keeper 12 to move downwardly, and the projections V16 are received in the seat 6 of the bolt 4. When the keeper 12 moves downwardly,the latch 20 tilts on thev fulcruin piece 23, and
the finger 21 on the latch is received in the as depicted in Figure 2. The notch 31 in the key 30 permits the key to clear the ward 18 on the keeper 12, when the key is rotated with the barrel 24.
Suppose that the parts are in the position shown in Figure 2. Then the key 30 may be slid into the slot 25 of the barrel 24, and the beveled end 33 of the key, cooperating with the keeper 12, within the opening 17, raises the keeper.` When the keeper12 is seat 11 ofthe bolt 4. The parts now appear raised, the projections 16 are'detached from the seats 6 in the bolt 4,V and the latch 20 tilts on the fulcrum piece 23, so that the finger 2l of the latchfis disengaged from the seat 11 in the bolt 4. `When the barrel 24 is rotated by the key 30, the eccentric 27 on the barrel, cooperating with the link 7, retracts the bolt, the second eccentric 28 coming around again into its uppermost position. With-in the opening `17 of the keeper l2 to support the keeper in the position shown in Figures l and 4. f .Y
The lock is devoid of springs, and-in order to operate, it must be placed in the position shown. inFigures l, 2 and 4, the part to Which the reference character T is applied, in. Figure l, being considered the. top of the lock, and the terms upper, lower and the like, having been selected accordingly, in the foregoing description.
