' This-invention relates to an indicator for determining the timing of the sparking relative to the pistons.
An object of the invention is the PlOVlSlOIl of. a device which is adapted to be inserted within the usual spark plug opening in a cylinder head of an engine or determining the piston during-the firing adapted to be ignited.
A further object of the invention is the provision of adevice adapted to be applied to cylinders having various types of heads for indicating the osition of a piston in the cylinder when t e-ignition should occur on the compression stroke of the engine.
This invention will be best understood H froma consideration of the following del tailed descriptiomin view of the accompanying drawings forming a part of this specification; nevertheless it is to be understood that the invention is not confined to the disclosure, being susce tibleof such changes and modifications whic shall define no material departure from the salient features of the invention as expressed in the appended claims. Figure 1 is a'veitical section of an engine showing my indicator'applied thereto,
1 Figure 2 isa plan view of the indicator, Figure 3 is a vertical section of the indicator,
Figure 4 is a vertical section of a modifie form of the indicator, Figure 5 is a vertical section taken along the line 5-5 of Figure 4, and
Referring more particularly to Figures'l to 3, inclusive, an engine 10 is shown in section having a cylinder head 11. a cylinder 12 and a piston 13. In the cylinder head is provided the usual combustion chamber 14 having a threaded opening 15 into which is adapted to be screwed the usual spark plug.
A plug 16 having a threaded portion 17 and a passage 18 is screwed into the threaded opening 15 until the enlarged or tool-gripping portion 19 forms a stop for further movement of the plug. The upper end of the passage 18 is provided with internal threads 20 into which is screwed a guide 21. The upper end of the guide, as shown at 22, is knurled in order to provide for the ready rotation of the sleeve or guide.
A rod 23 having a lower or angularly disposed portion 24 1S slidably mounted in the guide or sleeve 21. The free end of the angularly disposed portion is provided with a point 25 adapted to engage the top of the piston. The upper end of the rod 23 is connected to a barrel 23 of a micrometer 26 of any well known type. The micrometer is provided with a knurled sleeve 27 which is adapted to be rotated for adjusting the micrometer. A pin 28 on the upper end of the micrometer is adapted to engage the lower end of an ad- 'u-stable rod 29. This rod is clamped between the members 30 and 31 by means of screws 32 while the upper end of the supporting rod 33 is also clamped by the members 30 and 31. The lower end of the rod 33 is reduced and threaded and screwed into a vertical passage in the plug 19. I i
he operation of my device thus described is as follows: The piston 13 is movedto the upper limit of a stroke and the point, 25 is placed in engagement with .the piston, as shown in Figure 1, and the micrometer isadjusted to register zero. Atthis time the rod 29 is moved down to'the position shown in Figure 3 with the lower end of said rod in engagement with the lug 28. The piston is then lowered and if it is desired to set the timing device at .100" the micrometer is then adjusted until it registers the above notation and the rod 29 is moved until it engages the finger or lug 28. The piston then is returned slowly and carefully until it comes into engagement with the point 25 whence the timing gear may be so adjusted that the spark will occur at this position of the piston. The operator readily determines when the piston engages the point 25 by the fact that the piston will resist further upward movement when engaged, care must be taken, however, to prevent any rapid movement during such operation.
Referring more particularly to Figures 4 to 6, inclusive. it will be seen that a the top of the piston 40.
modified form of the arrangement is pro- A rod is pivotally connected, at 51, to the outer end of the rod 45 and has at'its lower end a micrometer 52 of any well known type. The lower end 53 of the micrometer is adapted to contact at predetermined times with a stop rod 54 carrying apair of brackets 55 which are clamped to the rod and also to a rod in engagement with the upper face of t e piston 40 when said piston is in its uppermost position and the micrometer is so adjusted that it will register zero and the stop or bar 54 is moved into engagement with the micrometer. The piston 40 is then lowered and whatever micrometer adjustment is desired by the manufacturer of the timing device is then registered on the micrometer 52 by turning the same until the proper number is indi-" cated. At this time the point 48 is lowered and the piston 40 is returned until it engages the point 48 whence the timing device may be set for permitting the current to pass through the spark plug connected withthe cylinder 41 at the proper time.
