M nvipnovsnsnr in PAD Ane TRUNK-Locas.

` Wr-s-v- The Schedule referred totn these Lettera Patentand melding part of the same. l

' To all whom, 'it 'may concern Be ii; known that I, ANDY M. ADAMS, of' Washington city', in the Bistrict of Columbia, have invented certain'uew and useful Improvements in Locks; and I do hereby declare tho'following to be a iull and exact description thereof, sufficient-, to enaliie those skilled in the art to which my invention appertains to make and use `the saine, reference being had to the accompanying drawing, making part of this specification, and to thc letters and ligures marked thereon.

My invention relates to that'class oi' locks known as spring or seltlihstening locks, and is particularly applicable to trunk andV padlocks, aud consists iu such an arrangement of the parts that the rising-block or its equivalent throws out the hasp, and prevents the dog from engaging with the bolt. f

In the accompanying drawing- Figure lfrcpresents my invention as applied to a padlock., the top plate ofthe lock being removed, and all the parts locked;

Figure 2 represents a similar vieiv of the invention, but showing theinterior parts unlocked Figure 3 is a similar view of the device with the hasp thrown out;

Figure 4 represents the shell oi' of the parts removed;

Figure 5 represents theinuer side of the upper plate; I

Figures 6, 7, and 8 represent parts of the lock, which will be described fully hereafter;

Figure 9 represents the key;

Figure l0 represents my-'invcntion as applied to a trunk-lock, showingthe same locked and the upper plate removed;

Figure 11 is a view similar to iig. 10, showing the lock opened;

Figures 13 and 14 are views ot' the lock similar to figsf10 and 11; and Q Figurcs12, 15, and 16 are parts of thelock, which will also be fully described hereafter.

A is the back or shell ofthe lock;

B is the hasp;

C is the sliding locking-bolt: and c is its spring, by which it is driven back.

o' is au extension of the rim passing down into the hot O, and forming its guide.

.D is a dog, which locks the locking-bolt in its seat in the hasp; and d is its spring.

E is a rising-block, by means of which the hasp i3 is thrown out of the lock, and the fooi; of the dog D held np out of tli sliding bolt C; eis its guide: and

y is its spring.

I is the pinion or pillar ofthe key; and r/ g are circular' guards, which occupy corresponding wards in the key.

h,g. 5, is a guide forthe'rising block E; and

'/i, same figure, is a guide for .the sliding'bolt U.

the lock wit-h some its spring c.

The operation of my invention vis as followsz.

.lhe lodi: being fastened, as shown in fig. 1, the key is introduced andl turned toward the right, which brings its under tooth in contact with the lower portion of'the dog I), thereby raising the foot of the same up out of the locking-bolt' C, and freeing the bolt. The key is stilhpassed around until its upper tooth engages with the end of the sliding bolt 0, pressing it forward out of its seat in the hasp B, and freeing the same. The rising-block E is then raised up Aby means of its spring' e', thereby throwing 'the-hasp up out of the lock, and holding thel foot of the dog D ,up out of the sliding bolt'G, as shown in riff. 3. .Y

tAs-soon as the hasp B frees'the sliding bolt C, the said bolt is forced, hack in position, by means ot' l To close tlf'lck, thefhasp'l is pressefdown 'into the same, and, by means of its beveled foot,

slides the locking-bolt 10' forward, passes down into the seatiu the samc until it strikes the rising-block E, which it forces down out ofthe bolt D, andits .toe c, passiugbelow the under surface oi' the bolt C, the said boli; slides back into its seat'in the hasp, securing the same; and the foot of the dog-1I), being Apressed down by its spring d inte the rear end of the.

sliding bolt C, locks the said bolt, in thehasp B, and the lock is securely closed. I In figs. 10 and 11 the hasp is double, and the siid ing locking-bolt is provided -with two catchesor feet. The spring e is formed so as to perform the' oice ofthe rising-block E, and the upper tooth of the key comes in cont-act wit-h'tlre side oi' the bolt C at c', iusteadof at; the end of the same.

In figs. 13 and 14 the spring e' is placed as a saddie on. the uppjer side of the sliding locking-bolt C,

and raises the dog 1) by coming. in contact with its shoulder or spur el'.

'The sliding bolt; C in these figures is out out on its inner side for the reception of' the dog D, as4 shown more fully in iigs. v15 and 16, instead of in its center, as shown in theother figures. Y

Having thus fullydescribcd the nature and operation of my invention,

What I claim as new, and Vdesire to secure by Letters Patent, is-

The sliding bolt 0, dog D, and basp B, in combination with the risinfr-block E or its e uivalcntwhen' arranged to throw out the hasp and support the dog D,l substantially as shown and described.

In testimony that I claimthe foregoing mproved lock, I hare hereunto sci; my hand this 2d day 4of' 'May, 1870.
