1 Claim.

This invention relates to new and useful improvements in watch tools and the primary object of the present invention is to provide a tool for removing a selected face of a Waterproof watch case.

Another important object of the present invention is to provide a watch tool including novel and improved means for gripping the face of a watch case to be removed in such a manner as to prevent marring or scratching of the watch case.

A further object of the present invention is to provide a watch tool that is simple and practical in construction and in use.

A still further aim of the present invention is to provide a watch tool that is strong and reliable in use, neat .and attractive in appearance, small and compact in structure, relatively inexpensive to manufacture, and otherwise Well adapted for the purpose for which the same is intended.

Other objects and advantages reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming part hereof, wherein like numerals refer to like parts throughout, and in which:

Figure 1 is an elevational view of the present watch tool;

Figure 2 is an enlarged longitudinal vertical sectional view taken substantially on the plane of section line 22 of Figure 1; and

Figure 3 is an enlarged transverse vertical sectional view taken substantially on the plane of section line 3-3 of Figure 1.

Referring now to the drawings in detail wherein for the purpose of illustration, there is disclosed a preferred embodiment of the present invention, the numeral l6 represents a tubular body or cylinder that is closed at its lower end by an integral end, plate [2 having an outlet nipple I4 projecting therefrom. The upper end of the cylinder I6 is externally threaded as at I6 to receivably engage an internally threaded closure cap or packing gland I 8 having a knurled surface 20 and a relief port 22.

Workable in the cylinder I 0, is a piston 24 including a piston rod 26 that is slidably mounted in the central guide opening or bore 28 provided in the packing gland l6. Rigidly secured to the outer terminal of the piston rod 26, is a stop member 30 which is provided with an aperture 32 in which there is removably positioned a handle bar 34.

The numerals 36 and 38 represent a pair of arcuate arms that are disposed on opposite sides of the body It at substantially the longitudinal center thereof. Removable fasteners 66 are employed for securing these arms 36 and 38 to the cylindrical body. The upper free portion 42 of the arms 36 and as extend in spaced parallelism outwardly from the upper end of the cylindrical body It and connected by an elongated, removable shaft i l supporting a spacer sleeve 46.

Frictionally engaging the nipple I4 is the central bore 38 provided in the reduced end of a resilient suction cup 52. This cup 52 has a bore 54 that aligns the bore 56 provided in the nipple. To assure the attachment of the suction cup 52 relative to the nipple 14, there is provided a split band 58 that tightly embraces the reduced end 56 of the suction cup and is connected by a fastener 69 to retain the same against the outer periphery of the nipple and the upper extremities 62 of the reduced end against the closure or end plate [2.

In practical use of the device, the suction cup 52 is placed against a selected face of a watch case (not shown) that is to be removed within the piston 24 bearing against the closure or end plate l2. By holding the sleeve 46 with one hand and pulling outwardly the piston. rod 26, by the bar 34, the cup will adhere tightly to the face of the watch case due to the suction existing in the cup 52. It is then merely necessary to hold the watch case in one hand and rotate the cylindrical body If! by the sleeve 46 to conveniently and readily remove the face of the watch case from the watch case.

In view of the foregoing description taken in conjunction with the accompanying drawings it is believed that a clear understanding of the construction, operation and advantages of the device will be quite apparent to those skilled in this art. A more detailed description is accordingly deemed unnecessary.

It is to be understood, however, that even though there is herein shown and described a preferred embodiment of the invention the same is susceptible to certain changes fully comprehended by the spirit of the invention as herein described and the scope of the appended claim.

What is claimed as new is:

A watch case opener comprising a tubular body having a closure at one end, a nipple carried by said closure, a resilient cup carried by said nipple having a port aligning with a port in the nipple, means removably securing the cup to said nipple, a removable closure for the opposite end of said body, a piston reciprocable in said body for pro- 4 REFERENCES CITED The following references are of record in the file of this patent:
