To ALL W'Hoiu IT MAY coNcnnN;
Be itknown that I, EDWIN A. BARROWS, of Willimantic, in the county of Windham, and State of Connecticut, have invented a new and improved Safety Lock; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the saine, reference being had to the accompanying drawing, forming a part of this specification, in which- Figure 1 represents'a front elevation of this invention.
Figure 2 is a longitudinal vertical section of the same, the line x x, lig. 3, indicating the place of section.
Figure 3 is a transverse section of the same, taken inthe plane indicated by the line y y, fig. 2.
Figures 4 and 5 'represent the internal mechanism in diderent positions.
Similar letters of reference indicate like parts.
This invention relates to an improvement in that class of locks which are provided with a combination mechanism to be operated by finger pieces in such a manner that the lock can only be opened by touching said linger pieces in the order correspondingto the set given to the mechanism. This mechanism consists principally of a sliding bar provided with four (more or less) sets of holes to receive the adjustable stops, and of a series of linger pieces and spring levers corresponding to the sets of holes in the sliding bar. Said sliding bar is set in motion by a spring latch whenever the drawer or door to which the lock is attached is closed, and by the motion of the bar a bolt is raised and the door or drawer is locked'. By touching the linger pieces in the proper order, the sliding bar is allowed to fly back to its original position, and the door or drawer is opened; but if by mistake or ignorance the'wrong inger pieces are touched, one or more dogs turn up and the lock cannot be unlocked until by a suitable key the sliding bar is pushed back to that position which it occupied l before theringer piece had been touched, and the lock cannot be unlocked except by touching the proper rnger l pieces. A
A represents a case, of cast or sheet metal, or of anyother suitable material. Through the ends ofi this case extend two rods, a b, which are stationary and parallel to each other. These rods form the bearings for the sliding bar B, and a spring, @pressing on a lug. projecting from said bar, has a tendency to press the same back in the direction of the arrow marked thereon in iig. 2. The bar B is provided. with a Series oiholes, ddl d2 cl3, divided in four (more or less) sets,veach set containing four (more or less) holes. These holes are intended to receive the pins e el e2 e3, by means of which the various combinations of the lock are effected. These pins project through the-sliding bar and they bea'r against the ends of spring arms ff1 f2 f3, which r are secured to the inner ends of short axles g g1 g2 g3. These axles have'their bearings in the front plate of the ease A,` and to their outer ends are secured the finger pieces h L h2 h3, so that by touching said linger pieces the armsfffz f3 can be turned up out of the way of the pins e e1 e2 e3. Under the arms fffzfs, and pivoted to the front plate of thc case, are the dogs z' t" i? is, which are loaded so thatthe same, when left to themselves, will assume the position shown in iig. 5; but if the sliding bar is pushed in tho direction opposite the arrow marked thereon in lig. 2, the pins e el e2 c, by striking said dogs, cause them to turn to the position in which they are shown in thc last-named figure, and they are retained in the position by the action of the arms fffzfa, which bear down on them, impelled by the springs pressing on the saine, as shown. If one of the finger pieces is touched so as to raise one of the arms ff1 fzfa, the corresponding deg turns up to the position in which all the dogs are shown in fig. 5. C .is a latch, which is pivoted to the end piece of the case A, and from which projects a stud, j. This stud bears on an inclined plane, p, onvthe edge of a lever, l, which has its fulcrum on a pivot, m,iand is subjected to the actionof a spring, n. By this spring the lever Z is drawn back to the position which it assumes in iig. 2 of the drawing, and the latch is pressed intowards the back plate of the case A; but if the drawer is pushed home, the head of the latch strikes the end of the recess provided to receive said head, and being forced out, causes thc lever Z to swing in the direction of the arrow marked near it in iig. 2. By this motion the end oi' the lever is brought in contact with the sliding bar B, and said bar is forced back against the action of the spring c to the position in which the same is shown in iig. 2. The end of the lever Z is provided with a hinged toe. it', which allows said lever to clear the sliding bar in going back. By this arrangement the sliding bar is set whenever the drawcr'i's pushed home, or if the lock is attached to a door, whenever the door is closed, and it is retained in position by one or more of the pins e e1 e2 e3, bearing against the corresponding
