ELECTRIC IMPLEMENT.

SPECIFICATION forming part of Letters Patent No. 295,652 dated March 25, 1-884.

Application filed October 25, 1883. (No model.)

To all whom it may concern.-

Be it known that I, ARTHUR H. KINDER, of Boston, county of Suffolk, State of Massachusetts, have invented an Improvement in Electric Implements, of which the following description,in connection with the accompanying drawing, is a specification.

My invention'relates to an implement or apparatus in which an electrical current is employed as the actuating-power for operating tools, the invention being shown as embodied in a device'especially intended for perforating paper for making stamped patterns for embroidery and similar work.

i The apparatus consists, essentially, of an electric motor composed of a field-magnet and armature rotatedthereby, the shaft or arbor of the said motor being provided with a flywheel, and actuating by a suitable crank or eccentric a rocking lever connected with a toolcarrying bar reciprocated thereby, the said bar being guided in a passage constituting a handle by which the entire apparatus may be moved about as desired, and the passage also being provided with a supporting-foot, which rests upon the material being perforated. The shaft of the motor is also provided with a chuck or clamp for holding small tools that operate with a rotary movement-such, for instance, as drills, gimlets, 850.

The drawing shows in side elevation an electric implement or apparatus embodying this invention.

The motor consists of a field-magnet, a, supported upon a frame or platform, I), having bearings c for the shaft d, upon which is mounted the armature and commutator, the said magnet and armature being of any usual type or construction, and having their terminals connected with binding-posts e e, to be con nected with the poles of the battery or other generator of electricity by flexible conductors or wires, permitting the free movement of the entire apparatus in all directions. The supporting-platform b rests on or has connected with it a guide-tube, f, the outside of which is shown in this instance as shaped to constitute a handle, 9,120 be grasped and held firmly in the hand of the operator, and contains within it a vibrating bar, h, carrying a vibrating too1,i, shown in this instance as a pointed rod or pin for perforating paper when supported on a yielding surface or pad. The bar h is connected with a lever, is, pivoted in a lug, k, at the under side of the platform I), and connected at its end with a link, m, attached to an eccentric-strap, it, operated by aneccentric on the shaft (1 of the motor. The said shaft (1 is also provided with a tool-holding chuck or clamp, 0, for holding rotary 0perating-toolssuch, for instance, as drillsand the other end of the magnet on may be provided'with a knob or handle, 12, to enable the apparatus to be steadily held by both hands in using it. The lower end of the guide-tube f is provided with a supporting-foot, recessed, as shown, to show the point of operation of the tool i, and made adjusta-ble'on the tube f, to regulate the depth to which the tool 73 may penetrate the material on which the foot r rests. By the employment of the vibrating shaft h and connecting mechanism is m it between it and the rotating armature, as shown, the said vibrating shaft and tool carried by it is operated with a comparatively slow but very powerful movement, much better adapted to that class of work for which the tool is intended than the more rapid but shorter and weaker movement produced by connecting the tool directly with a vibrating armature.

The entire apparatus forms a very complete device for actuating vibrating or rotary moving tools, as it has perfect freedom of movement, and can be held and guided by the hands of the operator, who is not required to devote any of his attention to the means for actuat ing the tools, as is the case when treadles or foot-power is used.

The apparatus may be used in many places I where it would not be convenient to use devices fiXed upon a table.

I claiml. The field-magnet and its rotary armature and shaft and supporting-platform therefor, combined with the guidetube connected with the said platform, the vibrating rod for carrying a tool guided in the said tube, and the rocking lever fulcrumed on the said platform, and having one arm connected with the said rod, and its other arm connected with the armature-shaft, substantially as described.

'2. The electromotor having a rotary shaft,

having one arm connected with the said rod, and its other arm connected with the rotary shaft, substantially as described.

In testimony whereof I have signed my name .1 5 to this specification in the presence of two subscribing witnesses.

ARTHUR H. KINDER.
