SPRING-MOUNTING IMPLEMENT.

Application filed November 25, 1921.

To all whom it may concern:

Be it known that I, FRANK W'. FIGK, a citizen of the United States, residing at 'Amsterdam, in the county of Montgomery and State'of New York, have invented certain new and useful Improvements in SpringMounting Implements, of which the following is a specification.

This invention relates to implements for placing helical springs in their casings or barrels.

The object of the invention is to provide a tool so constructed that a coiled helical spring may be held coiled and positioned where desired and after having its ends connected as desired and the binding wire released, the tool may be readily removed without disturbing the spring.

Another object is to provide a tool of this character having spring gripping jaws and equipped with self centering means-to effect an even hearing at any and every angle of the jaw carrying it.

Another object is to provide such a tool with means for releasing and withdrawing the tool from the spring barrel after the spring has been properly adjusted.

Another object is to provide a trigger releasable device for locking the tool firmly to the spring and to provide for the quick gripping of the tool on the spring and its quick release without the use of any screws or bolts.

IVith these and other objects in view, the invention consists in certain novel features of construction as hereinafter shown, described and claimed.

In the accompanying drawings Figure 1 represents a perspective view of a spring casing or valve with this improved implement shown applied and in the act of holding the spring in the barrel ready for its connection.

Fig. 2 is a side elevation of the tool with the parts in the position assumed when ready for gripping a spring.

The tool constituting this invention, while adapted for use in holding coiled helical springs and placing them in any desired position, is primarily designed for use in connection with the springs of talking machines. As is well known by. those familiar with the art, all springs furnished for talking machines or phonographs are sent from the factory inclosed in a metal ring and during the operation of placing the spring in its barrel it is necessary to remove the ring just before the spring is slipped into place. Ordinarily this requires a large amount of work and considerable pressure by the human hand and ofttimes the spring slips and consequently has to be rewound. The tool constituting this invention is so constructed that in one operation, it will hold the spring in place to permit the metal ring to be removed and will allow the operator to slip the spring into its proper position in the machine and by the use of the gravity trigger employed, as will be hereinafter more fully described, holds the spring in its proper position until the fastening thereof is successfully. completed and then on the release of the trigger by the operator the jaw of the tool will automatically open and release the Spring'so that the instrument may be removed from the spring and taken out of the barrel without in any way injuring the spring or the barrel.

The tool herein shown and described, is constructed for the use above stated, but obviously it may be made in various sizes to adapt it for use with springs of different sizes, such for instance, as those of a watch or clock.

In the embodiment illustrated, the tool 1 constituting this invention is shown constructed for use in mounting a coiled helical spring S in a deep spring barrel B, although obviously it may be used in connection with barrels of different sizes or depths.

This tool 1 comprises two cooperating gripping aws 5 and 10 pivotally connected to move toward and away from each other as will be presently more fully described. The jaw 5 has its front end laterally offset outward to provid a seat on its inner face for the self-centering attachment 6 which is loosely mounted on said jaw being shown provided with a laterally! extending shank 7 which extends loosely through an aperture 8 in the jaw 5 and is connected therewith by a pin 9 extending transversely through the outer endof the shank 7 and resting on the outer face of the jaw spanning the aperture 8 therein; This self-centering device 6 has a flat article engaging face, while its rear faceis inclined outwardly from its shankf7 toward its end to adapt it"to' rock on the inner face of the jaw 5 so as to conform to the spring tobe gripped thereby and provide an even bearing at any and every angle of the jaw.

The jaw 5 is shown made integral with a right angularly extending handle 1 which is bowed longitudinally outward and provided'on its rear edge with a laterally extending integral arm 3 which is curved 1ongitudin'ally and provided on its rear edge near-its front end with; ratchet teeth 2, for

a purpose presently to be'describ'ed.

It will thus be seen that the jaw 5 and-its han'dle't form a substantially' L-shaped member which cooperates with a member 15 the handle portion 16 of'which issubstantially parallel with the handle 4 of member 5, said handle 16 having an aperture 17 extending edgewise therethrough for the passage of'the arm 3 of the handle 1, as is shown clearly in Figs. 2 and Pivotally mounted in the aperture 17 is a pawl 18, the body of which is located outside said aperture while the shank 19 thereof extends into the aperture and is pivotally mounted therein. This pawl 18 has a'nose-20'for engagement with the ratchet teeth carried by the arm as is shown clearly in Fig.4, and at its other end has a finger grip 21 for releasing the pawl from the. ratchet.

The member 15 has a bifurcated head 22 at its inner or front end, the furcations 23 of which extend laterally from the front face of the headand are designed to receive between them the jaw member 5 and the shank or arm 11 of jaw 10, all of'which are pivotally connected by the pivot 24 passingthrough the free ends of the fu-rcations 23 and through the members 5 and 10 at their junction withtheir arms 4 and 11 respectively, (see Fig. 1).

The member 11 adjacent its connection with jaw 10 has a recess 12 in one side face thereof to receive the jaw member 5 as is shown clearly in Fig. 4. The free end of said arm llis-flatte'ned out and lies between members 15 and-4 being designed'to be en gaged-byi member 15 which controls the closing. movement of jaw 10 by engaging said" lever arm-'11- and'n'ioving-the jaw towards jaw 5. The jaw member 10 is heavier than arm 11 so that when the member 15 is moved out of engagement with the arm 11, the jaw 10 will swing by gravity into open position as shown in Fig. 3.

The jaw 10 is-concavo-convex in cross section and has its outer side edges bevelled as shown at 10 with which is designed to be engaged gripping fingers or guide lugs 26 carried by a slide 25', which is mounted to reciprocate on aw 10 and is designed as an ejector or release device for the spring when the jaws 5 and 10 have been opened and it is desired to withdraw the tool from the spring barrel without changing the position of the spring. Th fingers 26 are formed by slitting the slide 25' transversely and bending down the portions so slit at the ends of the slide to form these fingers and bending upwardly the intermediate portions 27 to form upstanding lugs with which are pivotally engaged one end of two links 28 and 29 arranged at opposite sides of the tool the other ends of said links being pivotally connected with obliquely and rearwardly extending ears 30 carried by thebifurcated head 22 of the members 15. This pivotal connection of 'the sliding member 25 bythe links 28 and 29 with the pivoted member 15 provides for the operation of the slide by the opening and closing of the member 15;

It is obvious that when the member 15 is swung into full open position, as shown in Fig. 8, that the slide 25 will be at its extreme forward movement, and when it is in closedposition, as shown in Fig. 4:, said slide will be at its extreme inward position.

The jaws 5 and'lO maybe of any desired length according to the depth of the barrel or casing Bin connection with which the tool is to be used, the deeper the barrel the longer these jaws will be since the tool is designed to insert a spring S in'the' bot tom of the casing as is shown clearly in Fig. 1, andto do this, it is necessarythat these jaws be long enough to reach the bottom and to have the handles 4t and 16 extend laterally over the upper edge thereof.

When the jaws are in gripping position and the tool held as shown in Figs. 1, 2 and 5, the gravity pawl 18 will drop into engagement with the teeth 2 of the ratchet 3 and lock the jaws against opening, so that when they are gripped around the coiled spring as shown in Fig. 1, the tendency of the spring to unwind will have no effect on the jaws and cannot'open' them untilsaid pawl is released.

- When it is desired to release the jaws from the spring, the finger grip 21 ofthe pawl is depressed to disengage the nose=20 thereof from the ratchet andthe' member 15 maybe then swung away from the handles 4 thereby permitting the handle 4- to' drop down and the" jaw 5 to open thus releasing the spring. The further opening of the member 15 will cause the links 28 and 29 to straighten out and move forward carrying with them the releasing slide 25 which moves forward against the upper edge of the coiled spring S thereby forcing the tool upward out of engagement with the spring and permitting it to be removed without in any way affecting the position of the spring.

From the above description, it is thought that the operation of the tool will be obvious, it being understood that the spring S to be placed in the barrel B is first gripped by the jaws 5 and 10 in, advance of the slide 25, the concave inner face of jaw 10 being adapted to fit the outer coil of the spring and the centering shoe 6 will engage the inner coil as shown in Fig. 1 and when so engaged the handles 4 and 16 are brought together to clampingly secure the jaws and are locked by the pawl 18 dropping into engagement with one of the teeth of the ratchet 3. The spring may be then inserted in the barrel as shown in Fig. 1 and after the ends thereof have been secured as desired, the tool is removed by releasing the trip member 18 and permitting handle t to drop down and thereby swing jaw 5 away from the spring and on the further opening of the member 15 cause the slide 25 to move forward and the tool be lifted upward out of engagement with the spring, so that it may be removed from the barrel without interfering with either the spring or the barrel.

From the above, it will be observed that the device may be quickly applied to or released from a spring by simply engaging the pawl 18 with the ratchet 3 or releasing it therefrom and that no screwing or unscrewing of bolts or screws is necessary.

The preferred embodiment of the inven tion is disclosed in the drawings and set forth in the specification, but it will be understood that any modifications within the scope of the claimed invention may be made in the construction without departing from the principle of the invention or scarificing anv of its advantages.
