Specification of Letters Patent.

Application filed August 17,1906. Serial No. 331,026.

To all 'whom it 'may concern:

.Be it known that I, THEODORE M. BEGHERER, a ,eiti zen of the United States, residing at Belleville, in the county of St. Clair, State of Illinois, have invented certain new and useful Improvements in Speed-Indi caters; 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 speed indicators and has for its object to provide a mcehanism of this character- Which may be readily adjusted to suit varying conditions and which, though thoroughly eflcient in action, will be of extremely'simple construction.

The invention has for its object furthermore to provide means for adjusting the indicating mechanism so that a specified size of pulley will not necessarily have to be used:

Broadly speaking` the invention resides in the provision of a shaft, a centrifugal speed actuating means for the speed indicating mechanism upon the shaft, means for adjusting the said centrifugal actuating means, and a speed indicating mechanism including an arm with which the shaft is engaged at one of its ends, the arm being adjustable with respect to the shaft ,to adapt the mechanism to different sizes of pulleys.

In the accompanying drawings, Figure l is a front elevation of the invention, Fig. 2 is a rear elevation of the said indicating mechanism, the rear face of the casing being broken away, and, Figs. 3 and 4 are detail vertical transverse sectional views on the lines 3 3 and 4 4 respectively of Fig. 2.

Referring more specifically to the drawings the nu meral 5 denotes a 'shaft which is journaled in suitable bearing brackets-(i which may be attached to any convenient support such as the bed of an automobile or the like.

The numeral '7 denotes a collar which is engaged upon the shaft 5 and is held in fixed position thereon by means of adjusting nuts 8 and 9 which are engaged upon the shaft 5 upon opposite sides of the said collar and in engagement therein, the said shaft being screw threaded as at lO'for a portion of its length for engagement f the nuts 8 and 9 thereon, it being understood that by adjusting the said nuts the collar 7 may be correspmdingly adjusted upon the shaft. The purpose of this adjustment will hereinafter be explained.

A pulley l1 is splined upon a sleeve 11 which is loosely engaged upon the shaft and is provided with,

an integral collar portion 12 and connected at one of their ends to the said collar portion 12 are leaf springs '13 which are connected at their opposite end tothe collar 7 and which are each provided intermediate its ends with a ball 14. The opposite end of the sleeve to its collar portion 12 is engaged through the bracket Gand is flanged as at 13 to prevent it moving away- Y shaft 20 'which is journaled at its ends in the front and rear face of the casing 1G. A pointer or hand 2l. is also engaged upon the shaft 20 and registers with numbers upon a dial 22 which is disposed upon the front face of the casing. f

The shaft 5 extends through an opening in one side of the casing 16 and has its end inwardly of the casing seated in a recess formed in a collar 24, which is provided with a bore for the reception of a threaded arm ,25 of a member 27 which is formed of the arm 25 and an arm 28 which extends at right angles to the said arm and is provided at its end with a right angularly turned portion 29 which works in a slot 30 formed in the segmental plate 17. A nut 26 is engaged upon the threaded arm 25 and bears against the underside of the collar 24 and serves as a means whereby the member 27 may be adjusted vertically to vary the position of its portion- 29 inthe slot 30. The collar 24 is provided with a flanged extension 3l which works in a guide 32 upon the rear face of the casing 16 and serves to support the said collar and the member 27.

From the above it will be observed that rotation of the shaft 5 will cause the same to move longitudinally thereby resulting in a movement in a corresponding direction of the member 27 and a consequent rocking movement of the segmental plate I7. This movement of the said plate will turn the shaft 20 and thereby indicate the speed of rotation of the shalt from which the shaft 5 is driven or the speed of travel of the vehicle to which the indicator is applied, and it is obvious thatby adjusting the member 27 vertically, the rocking movement of the plate 17 may be regulated to'suit various sizes of pulleys.

It will he understood that I do not desire to be lim; ted to the exact details of construction shown and described, for obvious modifications will occur to a person skilled in the art.

What is claimed is: A A device of the class described comprising a shaft :1rranged for rotation and for slidingr movement, a pulley which is stationary in regard to said shaft, centrifugal means for slidably moving the shaft when rotated, a memher connected with the shaft, a rockingmember engaged by the last named member', means for adjusting the rst named member with respect to the rocking member, a hand shaft and gear connections between said rocking member and said hand shaft. Y In testimony whereof, I afix my signature, in presence of two witnesses.
