IMPROVEMENT IN LOCKS-AND KEYS.

Specification forming part of Letters Patent No. 178,669, dated June 13, 1876; application filed March 21, 1876. v

To all whom it may concern:

Be it'known that I, JOHN JOSEPH PORTU- GUEZ, ot' the city, county, and State of New York, have invented a new and uset'ulImprovementin Locks and Keys, of which the following isa specification:

Figure 1 is a face view of -m y improved lock. Fig. 2 is a view of the same with the face-plate removed. Fig 3 is a view of-the same with the intermediate plate removed. Fig. 4 is a cross section of the same, taken through the line as 00, Figs. 1 and3. Fig. 5 is an edge View of the same, the case being shown in section. Fig. '6 is side view of the key, parts being broken away to showthe construction. Fig. 7 is a View of the key, showing the bits in another position. Fig. 8 is .a yiew of the key, showing the bits in a third position. Fig. 9 is alongitudinal section of the key, taken through the line y 3 Fig. '6.

Similar letters of reference indicate corresponding parts.

The 'object of this invention is to furnish an imptoved lock for safes, doors, and other places where two parts are to be secured together, and which shall be so constructed that it cannot be opened by any other instrument than the key made expressly for it.

The invention consists in the combination of the pivoted bar provided with an incline. and a notch, thepivoted bar provided with an arm, and the sliding bar provided with a plate having guards anda'lockingpin attached to it, and their springs, with the intermediate plate of the case for locking the pins attached to the bolt and its locking-bar, and for cover- -ing the key-hole through said plate, and in the key formed of the two parts sliding upon and shutting into each other and the third part, constructed and arranged to operate in connection with each other, as hereinafter fully described.

I will describe the mechanism of the lockin connection with the movements of the key by which it is operated, and'which I will first describe.

The key is madein three parts, AB U. The inner part A is made with two guards, a a and the lower end a of its stem projects in line with said guards a a to serve as a pivot to the key. The part vB has three guards, b

axis of the key as the guard a of the part A. The guard b is upon the end of the part B.

- The upper guard b is made hollow to receive a pin,"as hereinafter described, and the, lower sideot' the part B is grooved to receivev the part A, as shown in'Fig. 6; The stem of the 7 part A is made long, and passes through the hollow stem of the part B, which is made" shorter, through the hollowstem ot' the part 0, and its upper end is rigidly attachedtothe upper end of the said part (3, so that the said parts A 0 cannot turn upon each other. To

.the part 0 is attached the handle 0 which may be made in the form of a ring, or in any other convenient form. The cavity of thepart O is made larger than the stem of the part A, so that the hollow stem of the part B may be slippped up into the part 0, withdrawing the guards of the part B from the guards of the part -A, and allowing the parts A 0 to be turnedfwhile the part B. is held still. The upper part of-the stem of the part B has two slits formed in it, forming a tongue, b which is sprungoutwarda little, so as to enter a recess in the inner surface of the part 0, and thus prevent thepart- B from slipping up upon the part A accidentally. This tongue is pushed in to allow the part B to be pushed up by a small pin, 0 passing in through the part0, as shown in Fig. 9. The stem of the part B has a collar or head, b formed upon it for convenience in moving it up and down, and to limit its upward movement:

The case of the lock consists ofthe faceplate D, the intermediate plate E, the backplate F,'and the band G, which parts are bound together by't'our bolts, H. In the faceplate D is i'ormed the key-hole d. The part of the plate D through which the key-hole d is formed has a circular plate or cap, 6?, attached to it to give the stem of the key a longer bearing to keepitin position while being operated, without having its lower end steadied by a pivot. To the lower side of the plate d at the opposite sides of the forward end ofthe key-hole, are attached two pins, d which pass through the angle between the guards!) b of the key, and serve to prevent a key of any 'diate plate E. R is attached a plate, S, which has a short:

other shape frombeing inserted in the k'ey-. hole (1 and turned. As the keypasses through the key-hole d it rests upon a plate, I, which is provided with guards'i betweenwhich the guards of the key fit. The key is'then turned a half-revolution to the right. As the key comes into position the guard I) strikes the incline jof the angularpivoted arm J, and pushes said arm back, Withdrawing .it from the pin 70 attached to the bolt K, and which passes through a slot in the intermediate plate E, and from the pin ,i attached to the plate I. The guard b strikes the pivoted arm L and pushes it back, withdrawing its arm I from the pin ml attached to the: pivoted boa-r M, and which passes through a slot in theint'ermediate plate E. The'guard b strikes the projection 11/ formed upon or attached to the arm N and pushes it back. The arm Nis slotted longitudinally, and slides upon two .pins or screws, and carries with it the plate I. The arms J L N" are held forward by the three springs 0, attached to a block secured to the plate E. As the key completes its half-revolution it is pressed downward, which forces the. inner part A through the key-hole 6, formed inthe intermediate plate B. As the part A of the key descends it enters a holein, the eccentric U, and the guard a strikes a pin attached to a plate, P, which rests upon and is held up by a spring,,Q, attached to the baclcplate F. To the plate P is also attached a rod, R, which passes up through a hole or socket formed in orattached to the-interme- To the upper endof the rod pin attached to its inner end to en ter the hole in the guard b of the part B of the key, and

hold said partso that it will not be turned by Y turning the part A. The guard at strikes: a

pinattached to a spring, T, Jandpushes it out of a hole inthe eccentric U, and thus unlocks the said eccentric. The parts A O of thekey are then turned through an entire revolution, turning the eccentric U. As the eccentric U turns itstoe strikes the bar M, and pushes it. back, releasing the pin it attached to the bolt K. As the bar M moves back it pushes the spring-catch V out of its notch in the bolt K. I The toe of the eccentric U then strikes the ,11otch in said bar.

as herein shown and described.

The bolt K has two longitudinal slots formed in itto receive the screws k to compel the; said bolt to always move in a straights line,

and which are screwed into the back-plate I f or into the bar or, b'locksattached to. said plate, and'upon which the said bolt K slides. The key is removed by drawing it upward, which raises the part A through the key-hole. in the intermediate plate E, and into the part B, and then turning the keyahalf-revolution;

to the left. a

t a The lock is unlocked by turningthe key] a halt' rcvolution to the right, pushing the part A through the intermediateplate E,,l.l l(l fl1Illing it afull revolution to theleft. ,The key may i then be removed in thewmanner hereinbeforc 1 described.

Having thus described my invention, I claim as new and desire to secure by Letterslat- I ent- 1.
