CLAUDE SI-NTZ, OF GRAN-D BAP-IDS,
IGNITION-amuse.
Specification of Letters Pateizti ,Patented Feb. s, 1909.
Application filed March 18, 1907. Serial lie. 363,109,
To all whom it may concern:
Be it known that I, CLAUDE SINTZ, a citizen of the United States of America, residing at Grand Rapids, in the county of Kent and State of Michigan, have invented certain new and useful Improvements in Ignition-Timers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the artto which it appertains to make and use the same.
My invention relates to ignition timers for internal combustion engines, and its object is to provide an improved adjustable ignit-ion timer for such engines, to provide a simple-and durable device, to. provide a device so constructed that the parts are not liable to become loosened or displaced by use, and to provide the same with various new and useful features hereinafter more fully described and particularly pointed out in the claims. Heretofore in such devices there hasbeen great difficulty in maintaining the p arts in proper relation and adjustment due to the vibrations and rapid movement of the same.
My invention consists of the combination and arrangement whereby these difficulties are obviated, and a simple and reliable structure produced, which iseasy to manu factnre, and readily takenapart' as assembled, as will more fully appear by reference to the accompanying drawings, in which:
Figure 1. is :1 front elevation of a device embodying my invention with parts broken away to show the construction; Fig. 2. is a vertical section of the same on the line 2-2 of Fig. 1.; Fig. 3. a detail of the rotating head; and, Fig. 4;. a detail of the contact member in thehead. Like numbers refer to like parts in all of the figures.
1 represents a cup shaped case of any suitable dimensions and preferably provided with a transparent disk 2 to close the front of the same, said disk being secured in place between a ring 3 screwed into thefront of the case and the insulating ring 17.
rotative head 5 located within the case. This I hub provided with a socket 7 a set screw 8 and a key seat 9,'whereby it maybe attached to a rotative shaft in the usual way. The head 5 is cylindrical in shape and is recessed in the edge as at .l 0, transversely to its axis. Extending from this recess and radially across the axis .is an opening let within which is slidably inserted the tubular stem 12 of a yoke 11, said yoke being located and slidablewithin the recess 10 and also having its opposite fiat sides slidably engag ing the walls of the recess and retained thereby in planes at right angles to the axis of the head. In thisyoke is mounted a roller 15 journaled on a transverse pin 16 in the yoke, which pin abuts against the walls of the recess 10 and is retained in'pla ce thereby. In the tubular stem 12 is a spring ,13 which moves the yoke radially and thus yieldingly forces the roller 15 in contact with the inner surface of the insulating ring 17- in the periphery of the case. Extending radially through this insulating ring, and at regular intervals are bolts 18 of conduction.
material forming the insulated terminals of .the igniter circuits, theheads of which bolts are embedded in the ring with their surface exposed and engaged in succession by the roller 15 as the head is rotated by the-shaft to which it is attached. These'terminals are in number to correspond to the cylinders of the engine with which the deviceis to be connected, two terminals being shown in this case. Surrounding each bolt are insulating washers 17 and on each bolt are jam nuts 19, the outer nut being provided with recesses in which are inserted cotter pins 20 extending through transverse openings inthe bolts 18 to secure. the nuts from being loosened.
By the described construction, I am able to make a simple and compact structure of few parts with large bearings and easily constructed. The more delicate parts such as the spring and yoke are inc'losed within the head and impossible ofdisplacement or disorganizationby the vibrations of the device when running. It will also be noted that the bolts which form the terminals are 21 is an arm to hold the case from rotating and to adjust the case to determine the time so arranged that the hammering of the roller 15 cannot displace or loosen the same; and also that the device is readily taken apart or re-assembled as occasion may reuire.
What I claim is:
1. An ignition timer comprising a rotative cylindrical head having a recess in one side,'
- roller.
'head rotative inthe case and having a recess in one side,

An ignition timer comprising a cylindrical head, a case inclosing the head and having a bearing in its axis, an integral tubular hub-on the'head and ournaled'm the bearing, said head also having a recess with parallel walls and a radial opening communicating With the recess, a yoke in the recess and guided by the walls thereof, a tubular stem on the yoke, a spring in the.
stem, a roller journaled in the yoke, a ring of insulating material in the case and surrounding the head, and electric terminals radially inserted in the ring'andcase and successively contacted by theroller.
4. An ignition timer comprising a cylindrical head, having a recess in one side, said recess having walls spaced apart and in parallel planes at right angles to the axis of the head and also having a radial opening an lntegralcommunicating ith the recess, tubular hub on the head and provided with means for securing a shaft therein, a yoke in the recess and guided by the walls thereof, a pin in the yoke and retained therein by the said walls, a roller journaled on the pin, atubular stem on the yoke and movable in the opening in the head, a spring in the stem, a ring of insulating material surrounding the head and traversed by the roller, an adjustable case inclosing the head and ring, and a bearing in the case in which the hub is j ournaled.
guided by the edges flush With the wall the yoke.
6. In an ignition timer, a cylindrical and rotative head ha'vin a. recess in one-side, said recess having para l'el; wa'lls spaced apart, and also having a radial opening communieating with the recess, a yoke in the recess and having parallel sides slidably engaging the walls of the recess, a pin in the yoke and retained therein by the walls of the recess, a-roller journaled on the pin, a' iLlblllZlF'SlGli'l to the yoke and movable in the opening, and aspring in the said stem to move the yoke radially in the recess.
7. A sparker of the type set forth comprising an insulating block formed with an an nular opening, contact plates countersunk into said block and having their exposed of said opening, posts carried by said plate and projecting through said block, binding nuts on the edge of said post, a revoluble shaft projected'een trally through said opening, a disk fast on said shaft and formed with a straight sided opening extending radially to the edge thereof, a straight sided plug conformably fitting in said disk opening for radially sliding movement and formed with anaxial bore extending radially to the edge't'hereof adjacent the lower edge of said disk opening, an
expansive coil spring disposed within said-- bore and bearing against the underneath surface of the top of said plug and against the lower surface of said disk opening, said plug being formed in its upper surface with a transverse concave recess, a 'pin having its ends journaled in the side walls of said recess, and a roller carried by saidpm and havinga portion thereof projecting beyond the periphery of said disk, the periphery of said disk. beingspaced away from the annular edge of said first named openin x- In testimony whereof I in presence of two witnesses.
