Application filed-February 6,4920. 'Serial No. 356;723.

To {ZZZ whom it may cancer-n:

Be itknown that I, HAnRrsoN MACE, a cit-izen of the Dominion of Canada, residing at Sidewood, in the Province of Saskatchewan and Dominion of Canada, have invented new and usefulImprovements in Electric Engines, of which the following is a specification. I i I This invent-ion relates to electric or'magnetic engines, the object in view being to produce a simple engine of the class describedwhi'ch will operate in a positive manner and which may be easily'sta-rted so as to rotate the crank shaft thereoi'ineither direction aslniay'be desired.

A; further object oi the invention is to pro- "vide in connection with an engine of the class above referred to, manually operable means whereby the-engine may be started and stopped and reversed as to the direction oi rotation of the crankshaft.

lVith the above and other objects in view, the invention consists in the novel construction, combination and arrangement herein fully described, illustrated and claimed.

In the accompanying drawings: Figure. 1 is a plan view of the engine. Figure 2 is a. side elevation of the same, part taken in section along the line 2-2 of Figure 1.

which are fastened to the bed plate 1 by means of clamping straps 41 said electromagnets being therefore immovable. The magnets 2 and 3 are arranged in end to end and spacedrelation to each other so as to accommodate the back and forth or reciprocatory movement between'the same of an armature 5 shown in the form of a disk of soft iron having a series of pins 6 extending in opposite directions therefrom toward the mag nets 2 and 3 so as to be attracted by said magnets. The magnets 2 and 3 are formed with longitudinal bores or guideways 7 in which isslidably received a guiding member or rod 8 preferably of brass or any other suitable material.

I The'rod 8 extends entirely through themagnets2 and 3 and has connected thereto by means of a pivot 9 a pitman or connecting rod 10..which extends to the wrist pin ofa' crank disk 11 mounted ".fastion oneendof a crank shaft12which is journaled in bearings 13 "secured to and ex tending upwardly from the bed plate 1, said shaft being provided with a combined fly wheel. and'band wheellt as shown. The arj e 5 is rigidly secured upon the rod 8 y y l able means. i I

Thecrank shaft 12has fastthereon an cecentric 15 around which is an eccentric strap .16 having a holding arm 17 which is pivotally connected to a block 18 adjustable in a guide 19 which isadjustably secured to a support or arm 20 attached'to the adjacent bearing 13. wTheastrap :16isthus pivotally and slidably mounted so as to admit of the rotation of the eccentric 15 within said strap.

Extending from the strap 16 is a connecting rodor link 21, the same being connected by a pivot 22 to an upright lever 23 which is pivotally mounted at 241 on a support 25 secured to and extending upwardly from the bed plate 1. 'Pivotally connected to the lower end of the lever 23 is another connectby a joint 27 to an arm or extension 28 extending laterally from a longitudinally slidable switch bar 29, the latter being slidable through bearings 30 secured to and extending upwardly from the bed plate 1.

' Arranged in the path of the slidable switch bar 29 are two brushes 31 secured to and insulated from said plate 1. Flexibly connected to the switch bar, 29 is a circuit wire 32 extending to a battery or other source of electrical energy 33, a wire 34; extending from said battery 33 to the magnet 2 and by an extension wire 35 to the magnet 3. From oneofthe brushes 31, a wire 36 leads to the magnets 2 and from theother 1 brush 31 another wire 37 leads to the magnet 3. Due to sucharrangement of wires and circuits as the sliding switch bar 21) reaches the limit of its movement in one direction, one of the magnets is energized. and when said switch bar moves in the opposite direction, the other magnet is energized. As a result, the armature 5 is attracted back and forth or in other words a reciprocatory movement is imparted thereing rod or link 26,,the latter being connected 3 to and due to the mechanical connection described, the rotary motion is imparted to the crank shaft 12, from which by means of the eccentric controlled connection, reciprocatory motion is imparted to the slidable push bar 29 for the purpose above described, of alternately energizing and de-energizing the magnets in the way described.

In connect-ion with the mechanism above described, I employ a hand lever 38 adapted to be held at any point of adjustment by means of a notched rock 39 secured to the bed plate 1. A. rod 40 connects the lever 38 with the upwardly extending arm ll of the eccentric 16 so that by movement of the lever 38, the sliding switch bar 29 may be moved into contact with either one of the brushes 31 for the purpose of starting the engine in a certain direction as decided upon by the operator in advance. By the same means, the engine may be stopped and the direction of rotation of the crank shaft reversed.

The engine hereinabove described is simple in construction, reliable in operation and may of course be made in any size to give any desired power required.

What I claim is An electric engine comprisingin combination a pair of electr0-magnets having their cores provided with guide bores, a rod having its end portions slidable through said bores, an armature secured upon said rod and moveable between the magnet cores, a support, a crank shaft journaled through said support and having a crank portion, a link connected with said rod and with said crank portion, a magnet controlling circuit including two contacts, and a reciprocatory switch bar adapted to contact therewith alternately, an eccentric cam on said shaft, a strap encircling said cam and having an arm, a guide pivoted upon said support, a slide movable within said guide and piv otally connected with said arm, a rod connected with said arm and with said reciprocatory switch bar, and means connected with said guide whereby to reverse its position for bringing the switch bar initially in engagement with either of said contacts, said means comprising a pivoted lever, a link connected with said lever and with said arm, and a notched segment moved over by the lever and adapted to hold the latter in se lected position.

In testimony whereof I afiix my signature.

HARRISON MACE.
