Specification of Letters Patent.

Patented Aug. 1'7, 1909.

Application led November 18, 1908. Serial No. 463,202.

To all whom it may concern:

Be it known that I, Ror E. ADAMS, a citizen of the United States, and a resident of Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented a new and Improved Umbrella-Lock, of which the following is a full, clear, and exact description.

The purpose of my invention is to provide novel details of construction for a lock to be applied upon the handle of an umbrella, which will afford convenient means for locking the umbrella frame in closed adjustment, requiring the use of a suitable key for releasing the same and permitting the distention or opening of theumbrella- The invention consists in the novel construction and combination of parts, as is hereinafter described and defined in the appended claims.A

Reference is to be had to the accompanying drawings forming a part of this specilication, in which similar characters of referenceindicate corresponding parts in all the views.

Figure 1 is a partly sectional side view of the details of the improvement, substantially on the line 1-1 in Fig. 2; Fig. 2 is a partly sectional plan view of the details shown in Fig. 1., taken on the axial line 2 2 in said view; Fig. 3 is a transverse sectional view of parts, substantially on the line 3 3 in Fig. 1; Fig. 4 is a transverse sectional view on the same line as Fig. 3, but showing parts 0f the lock with the key removed; and Fig. 5 is an exterior side view of a portion of an umbrella handle and an end view of a key guard that is a detail of the invention.

In the drawings that show the construction and application of the invention, 10 indicates the stick for the umbrella that is tubular, and of suitable dimensions for effective service. Upon the tubular stick 10, a runner sleeve is slidably mounted that is tubular, and consists of an outer wall 11 and a concentric inner wall 11a secured to the outer wall at the ends of said parts, as shown clearly in Fig. 1. The inner wall 11aof the runner sleeve is slotted longitudinally, as shown at c in Fig. 1, and in said slot t-he head 1221 of a spring latch is adapted to work freely, said latch being positioned in the stick 10 and its head 12a working in a slot in the wall of the` stick, as shown in Fig. 1.

' The head 12a has the upper edge a thereof sloped so as to give said head wedge form7 the small end merging into the resilient thin limb 12 that is bent at o, producing a short leg, which is secured in the side wall of the stick 10, and it may here be explained that the head 12a is positioned lin the slot a, as represented in Fig. 1, when the umbrella is closed.

Upon the end of the runner sleeve nearest to the leg b of the latch piece 12, a collar is formed, having the periphery thereof radially slotted at equal intervals throughout its surface, these slots each receiving an end of a stretcher rod 13, that is pivoted therein as at a?, so that all of said rods may be spread apart or folded closely, as indicated in Figs. 1 and 2. The stretcher rods 13, as usual, are jointed at their opposite ends upon an equal series of bows that support the brous cover of the umbrella, and as these bows and the cover are of welllmown form and do not embody features of the invention, they are omitted from the drawings.

The stick 10 is connected with the bows and covering of the umbrella in the usual manner, and for convenience in illustration of the invention, these connections are omitted.

lNithin the stick 10, near the end thereof that is a distance from the runner sleeve and that is provided with a handle piece 14, a locking bar 15 is loosely located and adapted for longitudinal movement.

An eXpansible spring 16 is placed in the stick 10 between the end of the locking bar and an abutment pin c that is transversely secured in the wall of the stick. As shown in Fig. 1, the forward end (Z of the locking bar is sloped to give it wedge form, and as said end is normally pressed against the loweredge of the free rear end of the latch head 12a, this engagement will prevent the latch head from moving-inward, and consequently will prevent the umbrella from being distended.

The means for retracting the locking bar 15 is controlled by a key, and comprises the following details: Upon the handle piece 14, before it is secured upon the stick 10, a tubular lock case 14L is mounted and thus disposed concentric with the axis of the stick 10. At a suitable point within the case 14, an open recess is formed in one side 0f the locking bar 15, that terminatesat the end thereof which is nearest to the spring 16, in a transverse shoulder e, as shown in Fig. 2.

Transversely in two opposite perforations in the lock case 1an, and adjacent to the recess in the locking bar when the latter is in .normal position, a guide sleeve 17 is rotatably secured by its ends, said sleeve having a portion removed so as to produce a lateral opening therein throughout its length within the case 11i-1. Opposite the open side of the guide sleeve 17, the side of the stick 10 is cut away, and the locking bar 15 is so relatively positioned that the recess therein having the shoulder e, will be exposed in front of the open side of the guide sleeve.

A passage formed longitudinally in the guide sleeve 17 for the reception of a key, is in the form of a slot 7" that will loosely receive the body of a key such as is shown in Figs. 1 and 2. The key 18 is of a well known type, having a thin, flat body, enlarged at one end to form a bow or grip piece 18, and along one edge a plurality of toes or bits g project therefrom. A baffle plate 19 having a series of notches h formed in one straight edge, is secured upon the wall of the stick 10, at a point that will dispose said notches in the path of the key 18 when it is fully inserted into the guide sleeve 17 Upon vthe insertion of the key 18, it will be disposed as shown in Fig. 2, and in order to impinge the bits g of the key upon the shoulder e, it must be given a partial rotation along with the guide sleeve 17.

The baille plate 19 is so relatively positioned, that the bits on the key must pass through the notches 71, in the batlie plate in order to slide the locking bar a proper distance away from the head 12*L of the latch 12.

In operation, the act of closing the umbrella will cause the latch head 12 to be spring-pressed through the slot a in the runner sleeve wall 11a, and as the sloped end of the locking bar 15 is now engaged with the lower corner of the latch head, the stress of the spring 16 will prevent a depression of the latch head and consequently prevent the raising of the umbrella frame into expanded adjustment. rlhis relative adjustment of the latch head 12aM and locking bar 5, disposes the notch or recess in said bar, so that the shoulder e will be adjacent to one side edge of the slot or passage for the key, that is formed in the guide sleeve 17 Upon the insertion of the key 18 until the offsets c' thereon have contact with the end wall z" of the guide sleeve, the bits g on the edge of the key will be disposed opposite the notches 7L 'in the baffle plate 19, so that a turning movement may be given to the key in the direction of t-he shoulder e. The bit on the key that has been located opposite the shoulder e, will be iinpinged upon said shoulder as the key is turned along with the guide sleeve 17, which will push the locking bar 15 at its sloped `end Z away from the latch head 12a. Upon giving the key a half revolution from it-s first position shown in Fig. 2, against stress of the spring 16, and thus fully retracting the locking bar 15, the force of said spring will hold the key and the shoulder e engaged and the bar 15 slid away from the latch head 12a.

It will be seen that t-he slidable'movement of the ruimer sleeve 11 may now be eected, and the frame of the umbrella expanded, as the act of sliding said runner sleeve away from the handle piece let will impinge the sloped edge a of the latch head 12a upon the upper end wall of the slot a in the sleeve and the slot in the stock 10, thereby depressing the latch head and releasing the runner sleeve.

Then the runner sleeve is released, the key 18 may be removed, and the umbrella frame fully expanded until it is caught by an upper spring and held in expanded condition as usual.

lt will be noted that as the number of bits i formed on the key 18 must correspond with the notches 7L in the baffle plate 19, and be equally spaced apart therefrom, the lock cannot be operated except by a key of proper form.

The provision of the rotatable'guide sleeve 17 and a neatly-fitting passage therein for the accommodation of the key, prevents the use of a wire or the like for drawing the locking bar away from the latch head 122L and releasing the frame from the stick 10, so that it may be moved.

laving thus described my invention, I claim as new and desire to secure by Letters Patent:
