ELECTRIG-CIRCUIT-TIMING DEVICE:

, Specification of Letters Patent.

Patented Sept. 28, 1915.

Application filed April 17, 1915. seria no. 21,988.

To all "whom it may concern: I g

Be it known that I, RICHARD C. 'Ln'AKE, a citizen of the United States, and a resldent of the city of Rochester, in the county of venient and accurate adjustment and of.

maintaining said adjustmentwhen once made, and having all its parts rea'dily a'ccessible for inspection, readjustment or repairs. Y

Other objects and advantages will appear as the description of the invention progresses, and the novel features of the'invention will be particularly pointed out in the appended claims.

Reference is madeto the accompanying drawing forming part'of this specification, and which is a vertical partly sectional view of the improved timingdevice as used for making and breaking two electric circuits,

7 and with the segment carrying drum and the frame shown in end elevation;

upper bar 1, lower bar 2, and opposite end bars or. heads 3, connecting them. The end bars 3, have enlargedcentral parts in which i are journaled a shaft 4, to which is fixed.

a drum 5 in one of the peripheral grooves of which is shown a shortsegmental camplate 6, fastened by a set screw 7. The'shaft 4, may fixedly carry any approved device such as a crank arm 8, by which the shaft and drum may be turned together. To the 7 top frame bar 1, is fastened by screws or otherwise an insulating block 9, within a face groove'of which is fastened by abinding post 10, and a nut '11, the upper end of a contact finger 12. The 'post 10, also car'- ries washers'13, and nuts '14, 15, for securing a circuit wire. In the illustrated arrangement" the convexed resilient contact finger 12, normally engages a fixed 'contac t 16,

which is held in a face groove of an insulat ing block 17, fixed by screws or otherwise to the lower frame bar 2, and the finger also is adapted to leave contact 16, and engage an opposing; contact 18, which enters a shallow groove 1n the outer face of another insulatlng block 19. A binding post 20, having a faceted head entering a like shaped recess in the insulating block 17, passes outwardly through the two blocks 17 19, and the two contacts 16, 18, and'the block 19, has an inner recess receivinga nut 21, which had been screwed upon the threads of binding post 20, to fasten-the contact 16, to the block 17 before the block 19, was applied upon the inner block 17, over the contact 16. An insulating bushing 22, is slipped upon'the post 20,outside the nut 21, and on this bushing are placed 'a conductive bracket 23, aninsulating sleeve 24, and a washer 25, outside of which the post 20 has a nut 26, which fastens all parts 22, 25', 24, 23, '18 and 19, while holding block 19, securely to the outer face of block 17. Nash ers 27, and nuts 28, 29, provide for fastening a circuit wire to the binding post 20. The recessedhead of bracket 23, re ceives thenon-revoluble head of a binding post 30, having a fastening nut 31,' clamping the bracket 23, and this post carries washers 32, and nuts 33, 34, providing for fastening a circuitwire. It is obvious thata wire held 'to binding post 20, will be in circuit 7 only with the contact 16, and that a'wire Any suitable frame may be made with held to post 30, will be in circuit only with contact 18. The ends of the finger 12, and

contacts 16, 18, preferably have coacting platinum tips shown in the drawing.

The ad ustable parts of the circuit timing device held to the contact finger 12, will through the finger hole 35. Near its oppo- .site ends the clamp has slots 42, 43, through which and the finger slots 38, 39, are passed headed adjusting screws 44, 45, respectively, These screws are threaded into holes made in the opposite end parts of a concavo-convex bracket 1-6, lnwing an inv-sardly projecting yoke 17, in which is fifxed the axle 4-8, of an insulating roller 19, which normally enters that groove of the drum in which the plate 6, is fastened. The central back part of the bracket 46, is bulged outward to give a rocking bearing of the bracket on the inner face of the contact finger 12, next any one 01' the finger holes 35, 3G. 37, through which the clamp pin +l-1, passes to enter a recess 50, made in said bulged rear part of the bracket and thus determine the general operative position of both the clamp 40, and bracket 16, on the contact finger 12.

The operation is as follows: When the clamp pin i1, snugly'rests in the central. finger hole 35, as shown in the drawing, the centers of this pin and of the roller axle -18, and of the drum shaft 4:, range horizontally on a line about at right angles with a vertical line which would pass through the cen ter of the drum shaft. It obvious that it the bracket 16, be rocked on its center bearing on the finger 12,-the roller 49, will be correspondingly raised or lowered so as to stand farther from or nearer to the drum plate 6, to correspondingly delay or hasten the contact of plate 6, with the bracket roller 49, asthe drum is turned coiniter-clockwise from the position shown in the drawing. As the plate 6, strikes the roller 1:9, and rides under it, the roller is pushed outward there by moving thefinger. 12 from the fixed coata'ct 16, and engaging the finger with the opposed contact lS, thereby breaking one ci1= cuit through the binding post 20, and closinganother circuit through the binding post 30. It is obvious, that'eithcr contact 16, or 18, may alone'be used for making and breaking but one corresponding circuit. The screws 1%, -15, constitute one means for imparting the above named rocking movement to the roller carrying bracket and securely locking the bracket at the desired adjustment. H the screw 41, be turned clockwise and the screw 15 be turned counter-clockwise the bracket 16, will-berocked to raise the roller 4L9, and thus delay action of. drum plate 6, upon it, and a reverse turn'ii g :ol' the screws will lower the roller to hasten action of plate 6 upon it. As the like threads of the two screws -t-l-, a5, may be quite fine. the roller may be very nicely and conveniently adjusted for accurately timing the action of the drum cam-plate 6, upon it for precisely controlling one or more circuits to be made or broken by the contact finger 12. If at any time a greater range of vertical adjustment of the roller be desired, the screws 1-l-, 45, may be turned back in or entirely free from the bracket 16, to allow the clamp pin 11, to be adjusted in the uppermost finger hole 36, thus bodily raising the clamp and bracket and roller to assure longer delay of action of the drum plate 6, on the roller -19, and an adjustment of the clamp pin 41, in the lowermost finger hole 37, will corre spondingly hasten engagement of the drum plate 6, with the roller. The slots 38, 39, in contact finger 12, accommodate the adjust ing screws 1 1, 4:5, and permit their free rotation when the clamp pin -11, passes through any one of the three finger holes 35, 3G, 37. \Vhen the timing device pin 11, is in either finger hole 36, 37, the same nicety of vertical adjustment of the rocking bracket roller 19, is possible as when the pin is in the center finger hole It will be seen that all parts of this improved timing device are at all times fully open to inspection and are easily accessible for adjustment without disturbing either or both relatively fixed contacts 16, 18, or the binding post and line wire connections to said posts.

Although I have particularly described the construction of one physical embodiment of myinvention, and explained the operation and principle thereof; nevertheless, I desire to have it understood that the form selected is merely illustrative, but does not exhaust the possible physical embodiments of the idea of means underlying my invention.
