Description

May 27, 1947. w. E. BERLINCOURT WATCHMAKERS STAKING TOOL AND JEWEL SETTER Filed May 1, 1945 Patented May 27, 1947 UNITED WATCHMAKERS STAKING TOOL AND JEWEL SETTER William E. Berli'ncourt, Montreal, Quebec, Canada- Application. May 1, 1943, Serial No. 485,298 In Canada May 2, 1942 4 Claims.
This invention relates to watchmaking and particularly to a tool whereby a variety of operations can be accurately and efiiciently performed.
Its object is to provide a tool which will operate not only as a staking tool, a micrometer, a jewel setter, a calliper and pliers but will apply pressure in a novel and minutely controlled manner.
A further object is to provide a tool whereby delicate operations on small parts can be carried out without the risk of fracture or damage.
A further object is to provide a tool for accurate reaming and the measurement of small holes.-
Further objects will be set forth hereinafter.
Reference i made to the accompanying drawing in which:
Figure 1 is a side view of the device.
Figure 2 is a vertical section through the longitudinal axis of the sleeve and stump of Fig. 1.
The frame I mounted on the base H has the vertically bored end Ill in which is secured a sleeve l2, in which the punches 2 travel.
Mounted on the upper portion of the sleeve 12 above the part In is the cylinder 3 having a collar 38, at its lower end, secured to the sleeve l2 by the set screws 3|. This cylinder 3 is threaded internally at 32 and has vertical scales 33 and 33 on its outside.
A second cylinder 4 having a collar 40 at its upper end is threaded externally at 4! to mesh with the threads 32 of the cylinder 3. The upper end of the cylinder 4 is internally threaded at 42, for a short distance only. A screw plu 20 has its lower portion 2| threaded to mesh with the threaded portion 42 of the cylinder 4, and is bored at 22 to receive the head of a punch 2. The length of the screwed plug 20 is such that its cap 24 will not at any time contact the top of the cylinder 4. Small screws 23 are provided to secure the screw plug 20 to the head of a punch 2. This i provided to be used in reaming operations when the punch is to be rotated. The upper portion of the screw plug 20 has a central threaded bore 21 to receive a screw 26 through a knurled cap 24 which fits over the upper end of the screw plug 20. A leather washer 25 is inserted between the screw plug 20 and the cap 24. By means of adjusting the screw 26 the tension between the cap 24 and the screw plug 20 can be readily fixed, so that the cap 24 will continue to rotate when 2 the screw plug 25 is held by greater tension or is held stationary.
The cylinder 5 bored to fit over the cylinder 3 is secured by screws 52 at its upper end to the collar 40 of the cylinder 4.
This cylinder 5 has an enlarged knurled portion 50 while its lower portion 5| is bevelled. The lower edge of the bevelled surface is accurately scaled in parts.
The cylinder 3- has a vertical scale 33 of 25 mm. and the threading of the cylinders 3 and 4 is pitched to provide a movement up or down of 1 mm. for each complete rotation of the cylinder 4.
The base II has the usual rotating table l3 with a series of bores l4 adapted to be adjusted to the axis of the punch '2, and to hold a variety of stumps. A knurled screw l5 provides for holding the table l3 in any position.
.A variety of stumps l6 which are 10 mm. in height are provided to enter the bores M.
The operation of the device is as follows:
The cylinders 4 and 5 are unscrewed and removed.
A punch 2 is inserted into the bore 22 in the bottom of the plug 20, and secured therein by means of the screws 23. However, for some class of work it will be found advisable to have the punch 2 a friction fit in the plug 20, so that there will be a certain amount of give between the punch and the plug when the rotating punch meets the work, on being lowered.
The cylinders 4 and 5 are returned and cylinder 4 is screwed into the cylinder 3 a short distance.
The plug 20 with its cap 24 and punch 2 is then threaded into the cylinder 4 until the bottom of the plug 20 meets the bottom of the internal thread of the sleeve 4. Further rotation of the plug 20 will then be transmitted to the cylinder 4 and through the screws 52, to the cylinder 5. Rotation of all of these elements will continue until such time as the punch 2 makes contact with the work, mounted on the stump l6. Having a knowledge of the work to be done, the operator will now note the reading on the micrometer scale and will rotate the screw plug 29 to effect the further lowering of the punch 2, as is necessary to perform the required operation. When the resistance between the punch 2 and the work is greater than the ten sion of the leather washer 25 between the plug 20 and the cap 24, the cap 24 will rotate independently of the plug 20 and the other elements connected therewith, thereby protecting the work from damage. All operations are carried out by rotating the cap 24 and not by attempting to rotate the cylinder 5, otherwise the safety feature of the washer 25 will be lost.
If the knurled portion 50 is now rotated it lowers the punch 2 a distance of 1 mm. per revolution.
By means of the scale 5| the punch 2 can be moved by hundredths of a millimeter.
The scale 33 reads from 0 when a punch 2 is in contact with the surface of the table I3.
It has a scale 33 which reads from 0 when a stump of mm. is inserted in a hole M of the table I3.
The two scales 33 and 33' are provided so that one scale can be used for work which is shallow and the other for work that is deep. For in stance, if two operations following each other, are on work of greatly varying depths, normally the scale 33 would be used and stumps l6 of varying height used. This obviates excessive up and down movement of the micrometer cylinder with resulting less wear on the fine threads of the micrometer.
By means of this operation very minute and accurate measurements can be made between the lower end of a punch and either the surface of the table or of a stump.
The operation of the above described device is at all times smooth and accurate and work, which normally could only be done by highly skilled operators, using a great variety of fine and expensive tools, can now be carried out by semiskilled or even unskilled operators. All work of a repetitive nature can now be carried out with assurance that all pieces will be to set standards and limits of a degree unattainable with the most skilled of operators.
It replaces the violent and uneven hammer method now in common practice.
It eliminates any possibility of fracture or damage.
It operates the exact distance required and provides for uniform repetition. In jewel setting this is very important.
It applies suflicient pressure to carry out any operation that may be desired.
By means of suitable punches and the holes in the plate or stumps the tool can be used as a calliper, or as pliers.
By means of a scaled reamer mounted on the end of a punch, reaming operations can be carried out to /1000 of a mm.
Measurement of holes can be accurately obtained by such a reamer or sealed tool.
In the reaming operation the punch 2 is secured to the screw plug 29 by the small screw 23, and the screw plug 20 is screwed tight to the cylinder 4.
The rotation of the knurled portion will then operate the reamer mounted on the punch 2.
In all these operations the action, the movement, and the pressure are under perfect control.
The tool may be used with a hammer by simply removing the screw plug 20 and lowering the cylinders 4 and 5 to expose the upper end of the punch 2.
What I claim is:
1. In a watchmakers tool, a staking tool frame, a fixed vertical sleeve therein supporting a punch, combined with a micrometer mechanism operatin vertically on an extension to the sleeve, and an adjustable screw plug in such mechanism, means to couple the punch to such mechanism.
2. In a watchmakers tool, a staking tool frame, a fixed vertical sleeve therein supporting a punch, combined with a micrometer mechanism operating vertically On an extension to the sleeve, and an adjustable screw plug in such mechanism, means to couple the punch to such mechanism and means to secure the punch to the adjustable screw plug.
3. In a watchmakers tool, the combination of a staking tool frame having a vertical sleeve supporting a punch, with a micrometer mechanism mounted on the sleeve, comprising a fixed cylinder internally threaded and externally scaled, secured to the sleeve, a rotatable cylinder externally threaded to mesh with the fixed cylinder, a sleeve sliding over the fixed cylinder secured at its upper end to the upper end of the rotatable cylinder, having a knurled surface thereon and its lower edge scaled, a screw plug bored to seat the upper end of the punch and meshing with internal threading in the rotatable cylinder.
4. In the device claimed by claim 3, a knurled cap pivoted on the screw plug and means to adjust the friction between them.
