ARTHUR A. FINNEY, OF C HICAGO, ILLINOIS, ASSIGNOR TO FRANK LIVERANCE, JB., OF GRAND RAPIDS, MICHIGAN.
TIMER-SECURING DEVICE.
Application filed April 24, 1920, Serial No. 376,296. Renewed April 17, 1922. Serial No. 553,928.
To all whom it may concern:
Be it known that I, ARTHUR A, FINNEY, a citizen of the United States of America, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Timer- Securing Devices; 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 art to which it appertains to make and use the same.
This invention relates to a very simple and novel means for securing the timer con tact element of the timer used on engines of the Ford type on the timer shaft thereof, thereby eliminating several parts, reducing the cost of manufacture, and making the attachment and assembly of the timer especially easy. The usual means now used is to thread the end of the shaft and make an opening therethrough, the contact element being placed over the shaft, a pin passed through the opening in the shaft to with the contact element and hold it fixed relative to the shaft, a sheet metal cupliko member with an opening to pass the end of the shaft being placed against the timer contact element and partially over it so to preclude escape of the pin, after which a binding nut is put on the threaded end of the shaft and tightened, against said sheet metal member to secure the parts in place. lVith my invention, a single device is used to take the place of the pin, the cup-like sheet metal member and the securing nut, and at the same time the necessity of threading the end of the timer shaft is obviated. Furthermore, the device of my invention is absolutely secure against movement of any kind as distinguished from the loosening and eventual disengagement of the binding nut from the shaft, and the device is exceptionally easy to put in place in attaching the timer contact element to the shaft thereby reducing the cost of assembly and making it much easier to make an assembly of the timer construction particularly after a motor vehicle containing the engine is fully built with the radiator in place in front of and close to the timer, this being of chief value in repairing or replacing timers on used vehicles.
My invention has for its primary object and purpose the production of a device capable of attaining the above described noted ends and one which is fully capable of indefinitely withstanding the work it is designed to do.
For an understanding of the invention, reference maybe had to the following description, taken in connection with the accompanying drawing, in which,
Flg. 1 is an end elevation showing the timer shaft and contact element, with my invention applied thereto.
'Fig. 2 is a vertical sectional view taken longitudinally through the timer construction shown in Fig. 1, and
Fig. 3 is an enlarged perspective view of the securing device of my invention.
Like reference characters refer to like parts in the different figures of the drawing;
The shaft 1 on which the cont-act element of the timer is mounted has a front end 2 of somewhat reduced diameter through which an opening 3 is made. Over this end 2 of the shaft the timer contact element is placed, which includes a sleeve 4 from which an arm 5 projects and on which a lever 6 is mounted. A contact roller 7 is mounted at one end of lever6 while a spring 8 is attached to the opposite end of the lever and also to a second arm 9 which projects from the sleeve 4. The outer end of the sleeve is slotted as indicated at 4 so that the slots thus made in opposite sides of the sleeve may lie in alinement with the opening in the shaft. This construction so far described is that commonly used with Ford engines in the timing mechanism, being enclosed in practice in a timer casing having contacts against which the roller 7 bears as is well understood. My invention is applicable to this timer and to all others made as substitutes for the regular Ford timer, all having the sleeve 4 slotted as at 4: incorporated in their construction.
The securing device of my invention comprises a clip 10 of tempered steel which is formed to closely clasp and grip the end 2 of the shaft, the clip being open on its under side so that it may be readily sprung over the shaft from above. Integral with the clip is a tongue which extends rearwardly from the upper rear portion of the clip being bent upwardly to make a shoulder 11 and then back horizontally as indicated at 12. A pin 13 is connected at its upper end and depends from said horizontal portion of the tongue as shown, and when the clip is applied to the shaft, the pin passes through the upper slotted opening t in sleeve e and downwardly into the opening 3 in the shaft.
This construction of attaching or securing device attains all of the objects ahove enumerated. It is a unit and is applied as one by merely springing the clip over the shaft. It is removed as a whole when desired. It obviates the need of threading the end of the shaft, though it is applicable to and fully workable with shafts which have already been threaded for the usual type of securing members. It, accordingly, may be used as a replacement of the usual. securing means Whenever a contact element of the timer is removed from the shaft even though the shaft is threaded and is applicable for repairs in constructions now made. The shoulder 11 cones directly at the end of the sleeve e and together with the pin serves as a stop to prevent any endwise movement of the contact element along the shaft, while the pin precludes any rotative movement of the sleeve on the shaft. Three separate parts are replaced by one and in new constructions the threading of the shaft is not needed. The invention is defined in the appended claims and I consider myself entitled to all constructions which fall within their scope.
I claim: 7
1. In combination with a timer shaft having an opening therein, a timer contact element mounted on the shaft and including a sleeve passing over the shaft slotted at one end to aline with the opening in the shaft, of a retaining member comprising a clip of spring metal adapted to spring over the shaft, an integral off-set tongue extending from the upper portion of the clip over the slotted end of the sleeve, and a pin fixed to and depending from the tongue and passing through the slot in the sleeve and the opening in the shaft, substantially as described.
2. In combination with a timer shaft havingan opening therein, a timer contact element mounted on the shaft and including a sleeve passing over the shaft, said sleeve having one slotted to aline with the opening in the shaft, of a means to hold said contact element against detachment from or rotation on the shaft comprising a single spring clip clasping the shaft and a pin connected thereto to enter the opening in the shaft and pass through the slotted end of the sleeve, substantially as described.
3. A securing device for timer contact elements, comprising a spring clip open at one side to spring over a timer shaft, a tongue extending laterally from the upper portion of the clip, said tongue being bent upwardly from the clip and then horizontally, and a pin attached to and depending from the end of the tongue, substantially as scribed.
41;. A. securing device for timer contact elements, comprising a spring clip open at one side to spring over a timer shaft, a tongue extending from the clip at point substantially opposite the open side thereof, and a pin attached to and extendingfrom the tongue and substantially paralleling a diameter of the clip.
5. In combination, a timer shaft, a timer contact element including a sleeve mounted on the shaft, said shaft having an opening therein and said sleeve being slotted at one end to aline with the opening, and a single unitary device detachably connected to the shaft and having a part entering the opening in the shaft and through the slotted end of the sleeve to thereby secure the contact element on shaft and hold the same against rotation with respect to the shaft, substantially as described.
6. A device of the character described comprising a substantially circular spring clip open at one side, an integral tongue on the clip extending rearwardly therefrom at a point substantially opposite to the open side of the clip, said tongue being bent upwardly to form a shoulder and then to the rear, and a pin connected at its upper end to the end of the tongue and depending therefrom back of the clip, substantially as and for the purposes described.
In testimony whereof I affix my signature.
ARTHUR A. FINNEY.
