LOCK.

Specification of Letters Patent.

Patented April 21, 1908.

Application filed November 18, 1905. Serial No. 287,918.

To all whom it may concern:

Be it known that I, FRANK S.'AL1AN'0, a citizen of the United States, residing at the borough of Brooklyn, in the .city of New York, county of Kings, and State of New York, have invented certain new and useful Improvements in Locks, of which the following is a s ecification, reference being had therein to t e accompanying drawings, which form a part thereof.

My invention relates to locks, and more particularly to a class of trunk locks em loymg a swinging hasp and a bolt or bolts a apted to be automatically actuated in closing the lock.

The main object of the invention is to rovide a lock wherein the bolt or bolts wi be seated within the lock cup and projected through an opening or openings in the side or sides thereof, and be capable of pivotal or I a swinging movement to draw them within or project them from,said cu A further object is to provide a lock wherein oppositely acting spring pressed bolts may be made in a single piece to lnsureuniformity in their action when locking or unlocking the lock, and by reducing the numberof working parts, to chea en the cost of production.

A further object is to provide such a lock wherein the bolts will be so disposed as to insure their operation without the necessity for such accurate finishing as will render the lock liable to become inoperative through continued use and the resultant wear on contacting surfaces.

A further object is to provide a lock wherein the bolt and the key controlled mechanism actuating same, will be compactly arranged within the lock cup, and held 1n place through the relation of the several parts to each other and to the hasp carrying said cup. And a still further object is to provide a lock of this character which will be inexpensive to manufacture.

The invention consists primarily in the combination in a lock of a lock cupcomprising an up er or tumbler chamber, and a lower or bo t chamber of smaller dimensions than said tumbler chamber having an 0 ening through the side thereof, a pivota or swinging bolt mounted in said bolt chamber having its head normally projected through said 0 ening, a spring acting on said bolt to normally project it from said bolt chamber, key controlled means whereby said bolt may be swung to withdraw its head within said stamped to shape.

pendently of said means, means supporting said cup, and a cooperating locking plate having an opening adapted to receive the portion of said cup carrying said bolt wherebolt chamber and said bolt may rotate indey said bolt may pass through said late and engage the under side thereof, an in such other novel features of construction and combination of parts as are hereinafter set forth and described and moreparticularly pointed out in the claims hereto appended.

Referring to the drawings: Figure 1 is a longitudinal section of the hasp plate, the hasp and the lock or socket plate, with the cup shown in elevation ;'Fig. 2 is a planview of the lock cup and the lock mechamsm therein, removed from the hasp; Fig. 3 is a section on the line 33 of Fig. 2; F1g. 4 is a plan view of the lock cup with the key controlled mechanism actuating the bolt or bolts removed; Fig. 5 is a bottom view of the rotary plate, and Fig. 6 is a plan view of the lock or socket late.

Like etters refer to like parts throughout the several views.

In the embodiment of my invention shown the body of a trunk or chest and B the cover therefor. Attached to the trunk or chest body A is a hasp-plate C to which is hinged in the usual and well known manner, ahasp D carrying a lock cup containing the bolt mechanism and the key controlled mechanism for actuating same. Secured to the cover of the trunk or chest B is a lock or socket late E having a depressedportion substantia 1y centrally thereof to form a seat for the lock cup, and having a substantially rectangular opening E extending diagonally across said portion to permit the passage of the part" of the ford a suitable engaging surface for the bolts themselves. In the cheaper grade of locks these parts are all made of steel pressed or The hasp plate C is secured in place by a single headed bolt F passed through a substantially central opening 0 in said plate. This manner of attachment is desirable and is commonly employed because of the facility in adjusting the hasp plate, the economy and the finish afforded by the bolt head, It has heretofore, however, been found that when a stamped hasp plate is used, the portion adjoining the bolt opening is not so braced or reinforced as to give stability to theplate, and that an additional operation is required to provide a suitable countersink for the head of the bolt when the nature of the plate permits such. To obviate these difficulties, I stamp or draw the metal centrally of said plate into a cylindrical column C extending downwardly to a degree which will bring the bottom thereof into engagement with the trunk or chest cover B, and form the top of said column into a bevel to form a countersink for the bolt head, at C said column thus being formed integrally with the hasp plate, and serving as a brace or reinforcement therefor to resist the strains thereon in attaching the plate to the cover.

The lock cup comprises a casing a comprising an upper cylindrical portion a forming a tumbler and a controlling plate chamber; a lo Wer substantially rectangular portion 1) extending diametrically across said portion a and opening thereinto, forming a bolt chamber, and a connecting flange or web 0 forming within said cup a suitable bearing for the controlling plate, and support for the tumbler and tumbler spring studs, and presenting downwardly a bearing face adapted to en gage and rest upon the socket plate E. A top flange a is provided to facilitate the attachment of the lock cup to the hasp D. The portion 1) has therein at diagonally opposite points bolt openings as I), said openings bein slightly below the flange or web 0. The bottom of said portion 1) is closed and has an opening centrally thereof for the key barrel or pin.

Seated in the bottom of the portion 1) of the cup a, as shown in Fig. 4, is the bolt mechanism. This mechanism consists of a single bolt casting composed of a central portion (1 pivotally mounted on the key barrel or pin a y means of an opening extending through said portion, and bolt heads f adapted to projectthrough bolt openings b The side of the portion (1 adjoining each said bolt head f as at d, is substantially straight and parallel with the walls I) of the bolt chamber, thus serving as a stop for said bolt heads by engagement with said wall,.the side opposite said portion (1, as at (1 being curved on a radius to permit the free swinging or turning of the. bolts. A spring seat 9 is formed by means of a recess adjoining the bolt head, the coiled springs g acting against said seat and the wall I) of the bolt chamber. These springs 9 act to normally project the bolt heads f through the bolt openings 1). The lower face of the bolt heads f is beveled in the usual manner to cause the engagement of said bolts with the socket plate to force said bolts against the tension of the springs 9 within the bolt chamber, and the upper face of each said bolt head is parallel with and distanced from the flange or web a sufiiciently to ermit said bolts to be forced beneath the ock or socket plate E.

are when actuated, it is necessary to curve the ends thereof atf on a radius from the center pivot 12 to permit such movement. An abutment f 2 is formed on each said bolt head f within the bolt chamber and )rojected into the tumbler and controlling piatc chamber, by means of which abutments said. bolts are actuated by the key controlled actuating mechanism.

Seated on the flange or web 0 is a rotary plate It to which is riveted on the under side thereof so as to project into the bolt chamber, a narrow plate 'L of substantially the width of the bolt chamber at its widest point, from which point the sides thereof converge sufficiently to permit the limited rotation of said plate It. The plate 1; extends into close juxtaposition to the bolt portion (Z and the springs g, serving to maintain said parts in position in the bolt chamber, and one side of each end of said plate is projected as shown at t" to engage the abutmentf. The plate It has an opening therethrough adjoining an opening through both said plates for the key barrel, forming a key seat 72.. The opening for the key barrel in the plates h is larger than in the plate i, forming a seat It for a shoulder on said key barrel. I

The periphery of the plate 7t is cut away at different points to provide suitable guide surfaces contacting with the walls of the cup (t, shoulders h h" adapted to engage the abutments and. ways at 723-41." for the tumbler stud j and the tumbler spring stud 7c, and at the same time provide a suitable support for the tumbler lock piece h carried by said plate h, the tumblers m and their springs 12, and holding said last mentioned parts in place from beneath. The tumblers m and their springs n mounted respectively on the studs j and 7c in the usual and wcllknown manner are of well known construction and arrangement and will not be described more fully herein.

A washer 0 fitted on the studs and k and engaging the hasp D occupies any space above said tumblers and said springs, and between them and the hasp, thus preventing the displacement of these parts and the parts thereunder. The key barrel (5 which I preferably employ, has oppositely disposed shoulders e 0 adapted respectively to rest upon the seat 72?, and engage the hasp 1D, and

a downwardly projected end. 0 adapted to Inasmuch as the bolt heads f describe an turned therewith actuating the tumblers m leverage as is againstthe tension ofth eir s rings nin the usual manner to'free the 100i piece If and permit the key to engage the key seat h and the springs g. The key may be removed 'by' a reversal of this action permitting the springs g to force the bolt heads f outwardly until they have assumed their, former or locked position, the portion (1 engaging the wall at b and limiting the extent of projection thereof, the hasp D having first been raised. This restores the plate It 5/110 its former and locked osition also, ermitting movement of the bo t independent y thereof, however.

To lock the has D it is merely necessary to bring the hasp down until the lower POI? tion of the cup I) re isters with the o ening E of the lock or socl mt late E, and t e bolt heads f engage diagonally op osite points of said opening, whereu on slig t ressure will cause said bolt hea s, throug the bevel thereon to recede until they are forced within the bolt chamber sufiiciently to permit their passage through the said opening E, whereupon the springs g will immediately restore them to their former position, but beneath the said lock or socket plate E thus effectually locking said hasp with relation thereto; It will be observed that when said bolt acts independently of the rotary plate, the abutments f thereon merely swing away from those 72/ h i i on said plate, the springs g normally restoring the various parts to a position where said plate and its abutments will readily pick up and actuate said bolt through the abutments f The arrangement of said abutments also affords as great bolt chamber.

It will be further observed that by arranging the opening E diagonally across the socket plate E, the points of contact of the oppositely disposed swinging or pivotal bolts wi 1 be substantially the same distance from the hasp pivot, thus insuring a substantially simultaneous engagement of both bolts, avoiding all binding of same upon their pivot, and distributing the wear.

It is apparent that the bolt casting need not necessarily be in a single piece as shown, as the opposite ends thereof are subjected to the action of separate s rings and each head f is provided with an abutment f 2 acted on respectively by the rotary controlling late. In the interests of economy, however, prepossible in the area within the for to make each said bolt head integrally with the other, and such a construction also minimizes the wear of parts. It is not my intention, however, to limit my invention to the precise details of construction herein shown anddescribed, as it is apparent that such may be varied without departingfrom the spirit and scopeof my invention.
