ELECTRIC RETOUCHER.

Application led May n 20.

To all whom t may concern.

Beit known that I, VICENTE A. RAGAZA, a citizen of 4the United States, residing at Cebu, Cebu, yPhilippine Islands, haveinvented certain new and useful Improvements-in Electric Retouchers; and I do hereby declare the following to be a full, clear, and exact' description ofthek invention, such as will enable others skilledk in the artto which it appertains to make and use thesame.

This invention has relation to certain new and vuseful improvements in retouchers and has for its primaryobject, the provision of an electric retoucher which will be of simple construction and operation and highly etlicientin use. .n

The invention has for another object, the provision of any electric retoucher' which is specially adapted for use kby photographers for retouchingphotographic plates and lms and which will be operated in such a manner that the most delicatel operations of re-V touchingmay be performed quickly and efiiciently without danger of'injuryto the The invention has y'for a `further object, the

rovision of an electric retoucher which will ide ofisimpleand compact form and constructed in suchia manner that the operator orretoucher may conveniently hold the device and operate the switch thereof with` the thumb or a linger tostart or stop opera-I tion .of the retoucher, as desired. I

The aboveand other objects, in view, as will appear yas l the description .f proceeds, the invention consists in the novel combination and arrangement ofv coperating elements employed to produce the? complete' device, as will be hereinafter more specifically set forth, claimed and shown in theaccompanying drawings formingk a part of this application-and-in which Figure 1 is an elevationof the complete device.

in which similar reference characters designate corresponding parts throughout?y the several v1ews,1 indicates the cylindrical casmg' which tapers toward itsV forward'-y end and has an offset portion 2 on one side intermedlate its forward and-rearfends. The reary end is closed by alscre'w cap 3 mounted thereon and having'an' insulated'fface'fi positioned therein and withinv which is@ embedded oneend of the'leaf 'spring/5, the opposlte end of which is secured uponV the rear end portion of the armature 6, bysuitable securing' members 7. Tl1e'securin'g1members 7 also serve'to securev tothe armature 6y and the spring,v 5, the offset endv of the 8, which latter has the` platinum .tip or contactpointQ" on its outer or free'end portion normally contacting-,with the point of the contact screwy 10 which is threaded through the upper side of the casing 1, as clearly shown in the drawings. The armature 6 is preferably `of velozugated form and is normally spac'edfrom` the electromagnetll',which latter is `mounted upon theinner face of the insulating 'supporting plate 12 whichl is securedtthe'casmg 1 and closes the lovcf'erfopen side-ofthe offset portion of "said casingfl, suitablesel curin'gf members A13 being" 'employed `to` 'se cure the supporting-'plate 12 in `positio'nlopposite the"-adjustable contactfscrew "10.: A

is extended from` thel electromagnetffll-I to one point 19 of the'l switch- 14; Leading from the opposite `vpoint 720 of ythe switch 14 .is the current* conducting wire '21. which'conoffset 'portionf 2`-of the'ca'singal, onefof-the l wires being vconnected with `as also'shown in the drawings: A'wire 18 i nects with the contactscrewlO, thereby completing a circuit through the electromagnet l1 to energize the tlatter anddrawthe'armature `6 towardH the' magnet, `thereby v withyfdrzuvingthef'contact point 9 of'thespringiiS from" engagement with the "contact screw 10, .1

against the action of the spring 5. The spring 5 will immediately act to return the armature 6 and bring it to normal position,

thereby closing the circuit through the electromagnet l1 and denergizing the same. As soon as the point 9 of the screw 8 returns to engagement with the spring 10, however, the circuit will again be completed through the electromagnet l1 to energize the latter and cause a second movement of the armature 6 toward the magnet 11. This operation will be continued as long as the switch 14 is Closed over the switch contact points 19 and 20, causing a continual oscillation or vibration of the armature 6. The contact screw l0 may be readily adjusted in the side ofthe casing l to regulate the length of the movement or vibration of the armature 6 the advantages of which will presently appear.

The casing l is preferably formed of insulating material and has its tapered forward end open, as shown at 22 and through which projects the forward longitudinally slotted end 23 of the pencil or lead carrying tube 24, the inner end of which connects with the forward end of the armature 6. The lead member 25 of the retouching pencil may be readily engaged within the tube 24 with its pointed ends projecting therefrom and in order to securely clamp the lead 25 in position, l have provided a conical collar or tubular clamping member 26 having both ends open and its forward end rounded, as shown at 27. The inner end portion of the clamping member 26 is interiorly threaded, as shown at 28 for adjustable engagement on the exteriorly threaded forward end portion 29 of the tube 24, inwardly of the forward endof the casing l. It will therefore be seen that when the lead 25y is engaged in the tube 24 and the clamping members 26 engaged over the tapered end of the lead 25 and threaded upon the tube 24, the forward end of said tube 24 with its longitudinal slots therein will clamp around the lead 25, owing to the tapered shape of the clamping member 26, to securely hold the lead 25 in adjusted position, thereby presenting outwardly of the end of the clamping member 26 the proper portion of the tapered or pointed end of the lead 25. It will also be seen that the exterior diameter of the portion of the clamping member 26 extending through the open end 22 of the casing l is less than the diameter of the open end 22, thereby permitting free oscillation or vibration of the tube 24 and the lead 25 therein with the armature 6 during use of the device.

From the foregoing description, taken in connection with the accompanying drawings, it will be evident that it will simply be necessary for the operator to grasp the handle, move the device to position opposite the portion of the photographic plate or film to be retouched and hold the device while pressing inwardly the switch 14 to complete the circuit through the electromagnet 1l, thereby causing proper oscillation or vibration of the lead pencil 25 while the points thereof are in contact with the film. The most delicate operation in the work of retouching may be performed with this device even by those who are not sufficiently skilled to perform this work by hand, as such operations by hand call for considerable knowledge in this art and ability to move the hand freely and accurately at the wrist, and also move the arm at the elbow and shoulder. The lines can be applied to the film without injury thereto and in such a manner as to remedy defects in the film and also prevent printing of wrinkles and other objectionable lines and marks on the photograph which may either have been photographed from the subject or caused to appear on the film as the result of injury thereto or a slight defect in the film. This form of electric retoucher mty be readily employed in all operations of retouching and will sufficiently perform the work in a much shorter time than can be done by hand.

lhile the preferred embodiment of the invention has been shown and described, it will be understood that I do not wish to be limited thereto, as many minor changes in the details of construction and arrangement of parts may be resorted to within the scope of what is claimed without departing from the spirit of the invention.

That is claimed is l. iin electric retoucher comprising a casing having open ends and offset intermediate portion, an electromagnet mounted in said offset intermediate portion and insulated from the casing, a cap for closing one end of said casing, an armature to be attracted by said magnet, resilient supporting means for the armature carried by said cap, and a lead carrying member carried by said armature.
