CHARLES DAVID OLSEN, OF DENVER, COLORADO.
ELECTRIC MALLET OR HAMMER.
SPECIFICATION formingpart of Letters Patent No. 672,841, dated April 23, 1901.
Application filed January 18, 1900. Serial No. 1,852. (No model.)
To all whom it may concern:
Be it known that I, CHARLES DAVID OLSEN, of Denver, in the county of Arapahoe and State of Colorado, have invented certain new and useful Improvements in Electric Mallets or Hammers; and I hereby declare that the following is a full, clear, and exact description thereof, reference being had to the acthis specification.
This invention is an improvement in electric mallets and hammers of a peculiarly novel and simple type in which all the working parts are inclosed.
The invention can be used in connection with any direct voltage or alternating current, utilizing the electric energy thereof to strike slow or rapid and gentle or forcible The invention is designed for use as a dental mallet,a calking-machine,a riveting-machine, and for pounding, chipping, and drilling genstruction, the principle always remaining the same.
The invention further consists in the novel constructions and combinations of parts hereinafter claimed, and the accompanying drawings illustrate apparatus embodying my invention, referring to which Figure 1 is a longitudinal sectional view of the machine exposing the various parts, as follows:
In the drawings, A represents main magnet (with or without solenoid) with a hole or opening drilled through the center to allow the plunger J to .come in contact with the hammer B.
' B represents the hammer, made of soft iron turned to size or laminated as desired.
0 represents a main spiral spring of suitable gage fastened by solder or otherwise to brass shoulder or collar 0. c is fastened to otherwise to hammer B, first slipping over the turned shoulder b of hammer B. At this end of magnet A the wire 06 is carried through through a hole or opening bored through the upper portion of hammer B, enough wire be ing coiled before it is passed through the opening to allow for the working'distance or play of the hammer B.
'5 represents a piece of insulation forced into place or otherwise made solid in the upper part of hammer B. Into F is screwed the small screw f. f passes through the center of a small spiral spring H, thereby fastening the spring H solid to the hammer B. The terminal of the wire (I after passing through the hole in hammer B is then fastened to the screw f, holding small spiral spring H.
G represents a suitable weight fastened by solder or otherwise to upper portion of spring H. G carries contact-point E.
I represents contact-point attached to adjustable screw 7;.
7' represents a cylindrical brass piece fitted onto the back end of case P. In the center of r is a piece of insulation 9, which insulates screw '5 from case.
1? represents the outer coveringof the main or middle portion of the machine and consists of a cylindrical iron case which closes the magnetic circuit from the core Q to side of hammer B.
It represents a brass cap which incloses the battery connections. Brass cap R screws onto r. R has a hole or opening S in the end to allow twin cords to pass through.
W represents the contact-point on screw 2'.
X represents the contact-point on spring :12.
:1: represents the spiral spring fastened to a piece of hard rubber or other suitable insulation Z. The battery-wires or twin cords are connected with spring a: and brass cap R. The contact-points W and X merely close circuit when cap B. is screwed onto 1'.
J represents a plunger, with an adjustable shoulder K, suitably screwed on the plunger J and locked to limit and adjust distance-toward hammer B.
L represents a small spiral spring, which keeps the plunger J up to place to receive the blow from hammer B, the force of the blow v varying with the tension of the spring L.
M represents the terminal point of the wire leading from the magnet-coil A. M is screwed into the insulation m. M forms a contact with contact 0 at the pressure of button N.
N represents a switch-button which passes through a small opening illll and 'is supported by spring i,
H BESTAVAlLABLE com illiuder 'l einafter 'tion of-the tool tozbelused in the machine,
the tool being fastened at point Y withiu U.
' V also servest'o guide-plunger J.
Fig 2,is a separate longitudinal sectional View of hammer B'and adjacent parts.
Having thus described my invention, what V I therefore claim as new, and desire to secure by Letters Patent thereon, is-
"lfThe combination ota hammer 13, held in suspense by a spiral spring (1; with a small spiral spring H, attachedto the upper end of I containing the l miter B and holding a weight e, and
contact E, in suspense. 2. The combination of a small spiral spring -H, attached to the upper end of hammer B,
supporting Weight G, and contact E,-with an adjustable screw 6, having contact I, to make 7 contact with contact E. j
3. The combination of an adjustable screw 1;, having contact Llto make contact with contact E, with a spring as, having contact X.
4. The combination of a magnet A; hammer B; spiral spring 0; small spiral spring H, carrying weight Gand contact e; adj ust able screw '11, to which is fixed contact-point I; a plunger J; metal piece U, to adjust tension of spring L; and a switch to close and open circuit as set t'orth. I
