RETOUCHINGQPENCIL.

of Michigan, have invented certain new and useful Improvements in Retouching-Pencils, of which the following is a specification.

My invention relates to improvements in holders for carrying pencils such as are used a for retouching photographic negatives, &c., and its objects are: first, to provide a holder in which the pencils may be made to vibrate within the cylindrical part of the holder independently of the hand of the operator; second, to provide such a holder with which the pencil may be readily connected or disconnected; third, to provide a means in connection with the holder whereby the degree of vibration may be regulated as necessary; and, fourth, to provide a holder that may be readily made to hold any standard size of pencil.

I attain these objects by the mechanism, construction and arrangement of parts shown in the accompanying drawing, in which Figure 1 is a plan of the holder with the case shown in section on the line 11 of Fig. 2. Fig. 2 is a plan ofthe same with all parts shown complete and assembled, and, Fig. 3 shows the several .essential parts of the holder, and the pencil disconnected.

Similar reference characters indicate similar parts throughout the several views.

In the construction of these holders I make a handle 2 having a body portion 2 and a point portion 3 having a body portion 3 each of a proper size to fit closely upon the pencil so that when the pencil is once properly adjusted it will be held safely in position. These parts are separate and apart from each other, and a sleeve 1 is placed over them. This sleeve should have an inside diameter somewhat larger than the outside diameter of the bodies 2 and 3 of the parts 2, 3, so that when the vibrator is in action there will be room for considerable vibration of the pencil, which may be increased or diminished by placing the bodies 2 and 3' upon the pencil 8 to vary the distance between the beads 11, a, so that vibration may be given endwise of the pencil to a greater or lesser degree, as desired.

I provide for evenly controlling the degree of vibration, by forming a spring lip, as 7, in the sleeve and placing a ring 6 upon Specification of Letters Patent. P t nt d Applicationfiled January 31, 1918. Serial No. 214,772;

4 at the outer end of end of said coil being connected with any Sept. 17,1918.

the sleeve in such a. manner that by moving the ring longitudinally of the sleeve over the spring 7 the end of the spring will bemade to press heavily or lightly upon the surface of the body 3, as desired, the movement of the ringbeing indicated by the solid lines The form of spring here shown is simply indicative of the manner in which thisobject may be attained, and is not designed to be arbitrarily adopted, as many other forms of governor may be applied with success.

' The vibration of the pencil is attained by the use of a very fine spring metal helical coil, as indicated at 9, which is connected, at oneend, with the loop or ring 5, which latter is securely mounted upon the bearing the body 2; the other available kind of oscillating, or vibrating machine so that the oscillations or vibrations of themachine will be transmitted through the coil, not as electricity or as an electrical vibration, but simply from the delicate vibration ofthe coil itself, as induced by the action of the vibrator upon the coil.

It will be readily understood that with the pencil connected to the vibrator, as described, and held by the sleeve, as described,

' the point 8 of the pencil 8 will be given a slight trembling movement upon the negative, and thus retouch the negative without the danger, or possibility of making overshaded or straight heavy marks upon it,

thus insuring a much more even and satisfactory finish upon the negative, and, consequently, a much better 'eifect upon the prints than is possible with ordinary pencil work, as the amount of vibration, and the nature of the surface work are absolutely within the control of the operator.

10 and 11 are placed in the drawing simply to illustrate an available means for producing the desired vibration of the pencil when in use.

' The helical coil 9 should be made of very fine wire so that the most delicate movement of the vibrator willbe instantly transferred to, and exerted upon the pencil without any possible danger vibration at the point of the pencil, thus assuring the results hereinbefore mentioned. The best results are attained with the use of very delicately tempered spring wire tory movement through insulated wire, or Wire .Wound with cotton, or silk improves the results.

What I claim as new, and. desire to secure by Letters Patent of the'Un'ited States, is:

1. In a vibrating holder for retouching" pencils, a body fitted to fit closely upon each end of the pencil, adjusting beads on said bodies, a sleeve mounted loosely upon said bodies between the heads, a fine spring helical coil connected with one end of the body, and means for transmitting a vibrathe 0011 to the holder.

2.111 a vibrating holder for retouching pencils, an adjustable body slidingl 'mounted upon each end of the pencil eac 001' of this pet entmay be obtained for *havinga retaining bead thereon, a sleeve loosely mounted upon thehold'er between the beads on the bodies, a means for regulating the intensity of the; vibrations of the pencil, and means connected with the one end of the body to cause the holders and pencil to vibrate Within the sleeve.

3. Ina vibrator for retouching pencils, bodies secured to the pencil, a sleeve loosely mounted upon said bodies, means for caus ing the bodies and pencil to vibrate Within the sleeve, and means for regulating theintensity of the vibrations of the pencil Within the sleeve.
