IPERCY WATERS, OF DETROIT, MICHIGAN.
ELECTRIC TATTOOING DEVICE.
Application filed January 30, 1929.
My invention relates to an electrical marking device or tattooing instrument, and it has for its object to provide an improvement in devices of this character, the peculiar and novel construction of which is pointed out in the following specication and claims, and illustrated in the accompanying drawing, in which- Figure 1 is a in its entirety.
Figure 2 is a detail elevational view in section of the needle bar housing.
Figure 3 is a perspective partial view of the device in a persons hand showing the manner of operating the finger switcl Figure 4 is a detail sectional view taken on line 4`4 of Figure 2.
Figure 5 'is a detail sectional view taken on line 5 5 of Figure 2.
Figure 6 is an elevational view of the various types of needles used in the device.
igure 7 is a partial detail elevational view of the spark shield as applied to the device,

Referring to the drawing, 1 denotes an L- shaped frame of malleable iron having a pair of electro-magnets 2 vmounted in an upright position on the horizontal leg 3 of the frame 1 and secured thereto in any conventional manner. Extending from one of the sides and intermediate the ends of the horizontal leg 3 is a lseat 4 on which a vertical binding screw 5 is adapted to `be secured. Adjacent the seat the horizontal leg is a standard 6 the purpose of which is to be hereinafter described. The horizontal leg 3 terminates in a split portion 7 having a hole 8 formed therein for the reception of the end of a barrel or needle bar housing 9, which is adapted 'to be securely clamped to said frame 1 by means of a screw 10 passing through the split port-ion 7.
perspective view of the device partly The vertical leg 3 of the 'frame 1 terminates in a right-angle rearwardly extending proto have secured thereto jection 11 adapted through the medium of the screw 12 a leaf spring 13, having angular tapered portion 15. An armature bar 16 is arranged in spaced relation to the armatures 17 of the eleCtrOma/gnets 2, and is secured to the under side means of the screw 18, said y,armature bar 16 having formed on itsfree end a stud 1,9.
a flat portion 14 and an of the spring 13 by/ Serial No. 336,219.
Secured to the upper end of the standard 6 and perpendicular thereto is a binding post 2O having a contact-screw 21 extending therethrough and contacting the tapered end of the spring 13. A spark shield 22 of sheet Ymetal or other suitable material provided with a threaded opening 23 is secured in threaded engagement with the contact screw 2 1 to the under side of the binding post 20, the flared end 24 ofthe shield 22 extending in front of the point of contact between the contact screw 21 and spring 13, as clearly shown in Figure 7.
The barrel or needle bar housing comprises a tapered portion or well 25. A finger switch compris-ing a rubber cylinder 26 having embedded in itslwall a-contact bar 27 adapted to extend therefrom, is in turn molded or otherwise secured to the barrel 9. Projecting from the inner end of the contact bar 27 is a binding screw 28 to which one terminal 29 of the electric cable 29 is secured, the other terminal 29 being fastened to the binding post 5.
The barrel 9 is adapted to receive any one of the three types of needles A, B or C illustrated in Figure 6. Each needle comprises a needle bar 30 terminating in an eye 31, the other end ofsaid Vneedle bar having soldered or otherwise secured thereto a cluster of needles to be used in outlining as shown in A, or a point of tool steel so shaped as to be adapted for vengraving or etching, as shown in B, or another cluster of fine needles adapted for shading or lling in colors, as shown in C. Each needle bar 30 is inserted into the barrel through the hole 8, the eye 31 of said needle bar 30 being slipped over the stud 19 on the armature bar 16. To retain the needle bar 30 on the stud 19 a rubber band 32 or other suitable resilient means is provided, said rubber band 32,- extending from the needle bar 30 to the vertical leg 3 which has suitable notches 3 provided thereon for the reception of said rubber band.
One terminal 33 of the electro-magnets 2 is connected to the binding post 5, the other terminal 34 being directly connected to the metallic frame as at 35. Pressure applied on the contact bar 27 by means of the fore- .finger, see Figure 3, closes the crcuit'thereby causing the electro-magnets to actuate the make and break mechanism, the oscillations a metallic tubular member 9 terminating in is put in the lower of the armaturebar 16 causing said needle bar 30 to oscillate in a like manner; the 'current-being supplied either from a dry-cell battery or from a transformer connected to va house circuit.
., instrument that can be readily used for the marking or ,tattooing ofy the ear of. a ifurv animal aswell as for an electro .engraving purpose and for all other uses that instruments of this character are generally utilized.
VhatI claim as new and desire to secure by Letters Patent is 1. In an electric marking device, a metallic frame, an electro-magnet secured thereto, an
armature bar yieldingly connected to said frame and. adapted to be actuated by said electro-magnet to operate a make and break control, a barrel secured to said frame, a
" needle bar in said barrel and connected to said armature,- ,resilient means engaging said frame and needlebar to retain said needle bar in operative engagement with said armature, nd a finger control switch` on 'said barrel 'adapted to close the circuit to energize said electro-magnet.
2. In an electric marking device, an L- shaped metallic frame comprising two legs arranged at right angles to each-other, a plurality of electro-magnets secured to the horizontal leg, an adjustable contact screw carried on a vertical standard -constituting an integral part of said horizontal leg, a make and break mechanism secured to the vertical legin engagement with said'contact screw, an armature bar having a forwardly extending-lug secured to said mechanism, tubular guide means, a needle bar comprising an eye on its upper end in engagement with said lug and positioned within said guide means, resilient means retaining said needle bar in position, and a finger switch mounted on said tubular guide means.
3. In an electric marking device, an L- shaped metallic frame comprisingtwo legs arranged at right angles to each other, the
free end of the horizontal leg being'split and having' a hole adjacent its edge, a' tubular member adapted to fit within said hole, and a screw bolt adapted to draw said split portions together to clamp said tubular member in place.
4.' In an electricv marking device, a frame, a needle bar, anA electric actuating means therefor, a tubular metallic guide means for said needle bar,a rubber sleeve on said tubular member,a contact bar Aembedded therein and extending a short distance outwardly thereof, means to connect one terminal of an electric circuit to said contact bar, means to connect the other terminal to the frame, whereby when said contact bar is depressed to contact the tubular member the circuit will ge closed andthereby actuating the needle 5. In an electric marking device, an L- shaped metallic frame, a plurality of electromagnets mounted on the horizontal leg of said frame, a standard on said horizontal leg, a leaf spring connected to the vertical leg of said frame, an armature-bar secured to the under side of said .leaf spring intermediate its vends and adapted to be actuatedl by said electro-magnets, an adjustable contact screw carried bysaid standard adapted to engage the end of said spring, said metallic frame constituting part of an electric circuit, a inger control means to close said circuit to energize said electro-magnets, a spark shield mounted on said standard, marking means connected to said armature bar, guide means therefor attached to said frame, and resilient means retaining said marking means n operative engagement with said armature In testimony whereof I affix my signature.
