TOOL,

Application filed November 19, 1923,. Serial No. 675,530.

improvement in a tool and particularly that class of tool which is employed for removing the main or cannon pin from a watch. An object of the invention is the provision of a tool especially adapted for this use and so constructed as to provide means for engagdles.

ing the cannon pin of a watch firmly enough to remove it from its mountingand at the same time limited in its movement to prevent an excessive strain on the pin.

Another object of the invention is the provision of a tool of this class' having a series of notches formed therein for the reception of pins of various sizes and so constructed as to bring about a complete closing of the notches immediately after the engagement of the pin with the tool.

Another object of the invention is the provision of a tool of this class which will be simple in structure, economical of manufacture and highly efficient in use.

Other objects will appear hereinafter.

The invention consists in the combination and arrangement of parts hereinafter de scribed.

The invention will be best understood from a reference to the accompanying drawings which form a part of this specification and in which,

Fig. 1 is a side elevational view of the invention,

Fig. 2 is an end elevational view invention,

Fig. 3 is a top plan view of the invention in closed position, and,

Fig. 4 is a top plan view of the invention preliminary to complete closing of the same.

The invention in its preferred form comprises a pair of handles 7 and 8 which are pivotally connected together and provided with jaws l0 and 9 respectively which are adapted to approach and withdraw from each other upon the opening Or closing of the hanof the with a flattened portion 12 and 11 respectively adjacent the meeting edges thereof. Formed in each of the meeting edges of the jaws are semi-circular notches, which form, when-the The jaws 9 and 10 are each provided meeting edges are in engagement, circular.

openings-13. It will be noted that these openings are of various diameters to accommodate the device to the use with cannon pins of different diameters.

In use the jaws are brought into engage ment with the cannon pin 14 when it is in mounted position on the watch, the cannon pin resting in the notch which corresponds to the sizes of the cannon pin. As the handles are pressed together the cannon pin is engaged by the edges of the notches just preliminary to the meeting of the edges of the jaws throughout their length. In this way the cannon pin is securelyengaged and the further pressing ofthe same by the jaws prevented by the meetingof the edges of the same throughout their length. The width of the jaws, which is such as to per-. mit the jaws to extend beyond the edges, on each side, of the handles a distance substantially the width of the handles them selves, permits a number of openings to beformed therein to adapt the tool for use over a wide range of sizes of cannon pins. The provision of the jaws with a flattened portion adjacent the meeting edges permits the gripping of the pin close to the face of its mountings and thus assures a firm hold on the same.

While I have illustrated and described the preferred form of construction, I do not wish to limit myself to the precise form of structure shown, but desire to avail myself of such variations and modifications as come within the scope of the appended claim.

Having thus described my invention what I claim as new and desire to secure by Let-' in the other aw, a circular opening, the sev- 105 eral notches in each jaw being of various sizes, said jaws extending transversely of said handles, and projecting outwardly at opposite sides thereof.

In testimony whereof I have signed the foregoing specification.
