CHARLES W. SPONSEL, OF

HARTFORD, CONNECTICUT.

SPEED-INDICATOR.

Specification of Letters Patent.

Patented. Nov. 5, 1907'.

Application filed October 18. 1906. Serial No. 339,474.

To all whom it may concern:

Be it known that I, CHARLES W. SroNsnL, a citizen oi the United States, residing at Hartford, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Speed-Indicaters, of which the following is a specification.

Frequent-ly it is necessary to ascertain the speed per minute of a shait or other object, and it is desirable to have a hand and simple tool for accomplishing this result one ol such size that it maybe carried about the person, for instance, in a vest pocket.

Primarily the object of the invention is the provision of a light, portable tool which may readily be applied to the shalt or other object the speed ol which is to be tested, said tool carrying an indicator,

A lui-ther object ol the invention is the provision of a casing oi convenient size to contain the counting and indieating-mechanism, and the devices, few in number and simple .in construction, ior operating said mechanism.

Other objccts'oi the invention will hereinafter be set forth.

In the accompanying drawings Figure l is a vview in elevation of my improvement; Fig. 2 is a longitudinal vertical section thereoi; and Fig. 3 is a detail view partially in section.

Like numerals designate similar' parts throughout the several views.

Referring to the drawings, the numeral 5 designates a casing enlarged lor the greater portion of its length at 5f, and reduced to iorm a neck 52, said casing being prelcrably a single tube closed at its enlarged end by a cap 6, although it may be oi different construction, il desired, without departing from the invention.

Fitted in the reduced part or neck 52 ol the casing is a slidable bearing 4 having a bore et@ an inner head 7 andv an outer head 8 chambered at 9 to receive an anti-riction-device 10. said bearing being reduced between the heads 7 and 8, and the head '7 thereof normally engaging a shoulder l2 formed by reducing the end of casing 5. Designated by 13 is a. spiral spring litted upon a flanged tube 14, loose Within the casing, and bearing at one end against the head 7 and at its opposite extremity against the flange oi said tube7 as illustrated in Fig. 2.

Mounted in the bore 4/ of the slidable bearing 4 is a shalt or spindle 15, having a collar 15, and a head or cylindrical enlarged portion 152 provided with a reversely-beveled tip or point 153, shaped to fit the counter-sunk opening i'or the reception of the center in the end of a shaft. At the end opposite the head 152 the shaft or spindle l5 is provided with an inner clutchhead 16 having clutch-teeth 17. said clutch-head being located within the spiral spring 13, as illustrated in Fig. 2.

Designated in a general Way by 18 is a counting or i indicating-device the numerals ol which will appear through the slot 19 of the casing 57 as shown in Fig. 1. This device may be of any approved form suitable to be received within the casing to have its indicatingnumerals show through the slot in the same, and the driving-shaft ol said device is marked 20, and is provided with a clutch-head 217 having clutch-teeth 22, adapted when the device is in use to engage the clutchteeth 1.7 ol the spindle 15.

As above stated7 and as will be evident irom the drawings, the bearing 4 slides with the neck-portion 52 ot the casing and the inner head thereol is normally held against the shoulder 12 by the spring 13. When, however, the head 153 oi' the spindle 15 is applied to the shalt or other object the speed oi which it is desired to ascertain the push of the hand in which the device is held against the end-cap 6 of said casing will cause the bearing 4 to slide in Ward within the casing, and connection will thereby be made between the clutch-teeth 17 oi the spindle or shalt 15 and the clutchteeth 22 of the shalt for driving the counting and indicating-mechanism.

To pre\.'ent injurious end-thrust against the extremity ol the shalt or spindle 20, the hanged-tube 'lll is made oi suilicient length to engage o bearing 4 when the clutch-teeth are in ed and. thus to act as a stopY and prevent any ing oi the parts oi the indicator 18 when7 as stated7 the device is in use.

Alter the speed oi the shaft or other object has been ascertained the device is withdrawn from the shalt. and the spring 13 then immediately loi-ces outward the bearing et in which the spindle 15 is journaled and restores the parts to normal conditions with the clutchteeth disengaged, as illustrated in Fig. 2.

Anti-friction devices ol airy sort may be substituted lor the ball-bearings 9 to reduce the friction oi' the parts, and as they operate in the usual way liu-ther descrip tion thereol is deemed unnecessary,

A cap or sheath 23 may be applied to the part 15L of the spindle 15 ii desired to prevent interference oi the conical head or point 153 with the wall ol the pocket in which the article may be carried.

Changes maybe made in various details ol the mechanism without departing from the invention. and any suitable counting or indicating device may be substituted for that illustrated. Coinputations may be made in any usual way according to the style ol the countingdevice or indicator employed without departing from the invention.

Having thus described my invention what I claim isi 1r A speed indicator comprising a casing, a counting and indicatingdevice, a bearing' siidabie within the casing, n spindle carried by the bearing for engaging the device the speed of which is to be ascertained, and clutch-eiements for engaging said spindle with the counting,l and indicating-device.

2. A speed indicator comprising a casing, a counting and indicating-device carried by said casing, a device movable with relation to said casing, means for engaging said movable device With the counting and indicating device when the movable device is applied to an object the speed of which is to be ascertained and a stop for preventing end-thrust of the movable device and its engaging means against an element of the counting and indicating device.

3. A speed-indicator comprising a casing, a counting and indicating-device carried by said casing, a bearing slidable with relation to said casing, a spindle movable in a bore of the bearing, and carrying at one end a device for engaging an object the speed of which is to be ascertained, and at its other end a clutch and means for disconnecting said clutch from the counting and indicating-device.

4. A speed-indicator comprising a casing, a bearing slid able in said casing, a spindle rotatable in a bore of the bearing, a clutch-element carried by the spindle, and a counting and indicating-device actuated by said clutchelement.

5. A speed-indicator comprising a casing, a bearing slidable in the casing, a spindle rotatable in a bore of the bearing, and shaped on one end to engage an object the speed of which is to be ascertained, a clutch-element on the spindle, a counting and indicating-device, a shaft for actuating said device, and a clutch-element carried by said shaft, and adapted to engage the clutch-element of the spindle.

G. A speed-indicator comprlsing a casing having a slot, a bearing slidable in said casing, a spindle rotatable in a bore of the bearing and shaped on one end to engage an object the speed of which is to be ascertained, a clutchelement on the spindle, a counting and indicating-device visible through the slot of the casing, a shaft for actuating said device, a clutch-element carried by said shaft and adapted to engage the clutch-element of the spindle, and means for disengaging said clutch-elements.

7. A speed-indicator comprising a casing, a counting and indicating-devicemounted within the casing, a bearing slidable Within the casing, a tube Within the casing, a spring surrounding the tube, and engaging one end of the bearing, a spindle rotatable Within the bearing, and having a device at one end adapted to engage an object the speed of which is to be ascertained, a clutch-element on the opposite extremity of the spindle, and a clutch-element` carried by a member of the counting and indicating-device- S. The' combination, with a casing, of a flanged tube loose Within a part of said casing, a spring surrounding said tube, and bearing at one end against the flange thereof; a bearing slidable in' the casing, said bearing having a bore; a spindle rotatable in the bore, and having a head at each extremity; a shaft-engaging-device rigid with one of the spindle heads; and a clutch-element rigid With the other spindle-head, said clutch-clement being adapted to engage an element of the counting and indicating-device.

In testimony whereof I. affix my signature in presence of two witnesses.
