ARTHUR EDWARD THOMAS, OF LONDON, ENGLAND.

SPANNER.

Application filed November 13, 1924, Serial No. 749,703, and in Great Britain November 15, 1923.

This invention relates to spanners and refers particularly to such tools as are intended to be employed in connection with cycles or the like vehicles furnished or provided with free-wheel mechanism. Such mechanisms are furnished with a screwed sleeve having on its outer end a slot or slots to facilitate their manipulation.

The chief object of the invention is to provide an improved tool for engaging the said slot or slots so that the free-wheel may expeditiously and easily be removed from, or replaced on, the wheel-hub or spindle.

A further object of the present invention is to combine in a single tool, spanner-like or gripping parts for manipulating nuts and the like not only connected with'the freewheel gear but on other parts of the cycle or the like whereby a single tool can replace the usual spanner outfit required for such vehicles.

' According to the present invention the spanner or tool, which conveniently constructed from sheet metal of appropriate thick ness, comprises a body portion having enlargements at either end, one of which is provided with two teeth, studs. lugs or projections located diametrically opposite toeach other relatively to a central opening and adapted to engage with slots in the sleeves of the free-wheel mechanism. These teeth or the like may be formed integral with the spanner or be attached to or mounted therein in any appropriate manner, and the central opening allows the tool to be passed onto the end of the spindle on which the freewheel is mounted.

Surrounding the central opening is an outstanding ring or flange which is adapted to fit into or within the sleeve of the freewheel and the teeth are situated at the outer periphery of this ring or flange.

This end or head of the tool is conveniently approximately circular and at one portion near its outer periphery are situated two pins adjacent to which the outer periphery of the head has a curved part so that these pins can engage two holes in the end plate of the free-wheel mechanism.

In the outer periphery of this head also are cut at suitable points, jaws adapted to engage square, hexagon or other nuts. A rectangular projection is also furnished on the head to serve as a screw drlver.

Further, one or more box spanners are prolvided in the body or lever portion of the too In the other end'of the tool orthe part which normally serves as the handle there is provided a slot having portions of different diameters and these diameters are adapted to fit and grip, for example, the back cone, the front cone and the pedal-crank cone. r

. Referring to the accompanying drawings. Fig. 1 is a face view. I I Fig. 2 is a side elevation and Fig. 3, a section on the line 3-3 of Fig. 1. I i

In accordance 'with this embodiment of the invention there is formed at one end of the body part A an approximately circular head A furnished with a central opening.

provided in the outer end or edge of a sleeve of the free-wheel.

'These teeth or studs B, as already stated, maybe formed integral with "the head A of the tool; in the present example however they are formed integral with a cone C which fits within and is secured in the central opening in the head A and projects from the face thereof opposite to the teeth or pins B.

Formed integral with this cone C also is a ring or flange D. This flange-is of such diameter that it fits within the sleeve of the free-wheel and is of such depth that in engaging with the inner circumference of the sleeve it gives a bearing and steadiness to the tool when the teeth B are in position. The teeth B are situated at the outer periphery of the ring D and are integral with it, they pass through slots cut in the central opening in the head A.

The interior of the cone at C is formed to accommodate the cone portion of the hub disposed within the sleeve of the freewheel and it is formed so as to fit over the shoulder upon the spindle of the hub carrying the free-wheel, and the end of this spindle passes through an opening C in the cone.

The opening C is preferably hexagonal and can serve as a box spanner, such for example as is required for the nut of the back spindle of the cycle.

Around the periphery of the head A,- spanner jaws may be provided by cutting suitable slots in the material. In the example illustrated three such openings are provided. The opening-E is large enough to fit the nuts of the cotter pins used on the cycle and the jaws E and E are adapted to grip respectively the nuts of the chain wheel, the nuts of the bottom bracket, and the nuts of the brakemechanism.

Two pins F F are secured to the head A and project from the same face thereof as the teeth B. These pins are situated near the outer edge of the head A and the periphery of the head A between these pine is curved or recessed at F to fit onto or against the sleeve of the free-wheel so that the pins F F can engage with pin holes provided in the end of the free-wheel casing, thus providing a pin-spanner for this plate.

Gr represents a rectangular projection Which may be formed integral with the head A or attached thereto in. any appropriate manner and this projection is somewhat wedge shaped or tapered to form a screwdriver.

At the other end of the body A is formed an enlargement or head A and axially of this head is formed a slot which is of different widths or diameters throughout its length. The outer portion II of this slot is Wide enough to form jaws adapted to grip spanner-Wise the back bone and pedal-crank cone, while the inner portion H is adapted to engage the front cone in a similar manner.

Additional box spanners may be provided by forming properly shaped holes in the body of the spanner. In the present example two hexagonal holes J, K are provided and these may serve for example for use on the front spindle or other nuts.

What I claim is r 1. In a spanner for the free-Wheel of a cycle or the like, the combination of a plane body portion, an annular ring or flange on one face of said body adapted to enter a sleeve to position the face of the body portion against the end face of said sleeve, and a pair of'teeth projecting from the same face of said body and adapted to enter recesses in the end of said sleeve. 7 I V 2. In a spanner for the free wheel of a cycle or the like, the combination of a plane body portion having an opening therein for the passage of the wheel spindle, twoteeth projecting from oneface of said body portion at opposite sides of said opening adapted to engage in recesses in the end face of a sleeve. and a ring or flange on the same face of said body portion concentric with said opening, said teeth being located beyond the periphery of said ring but within the perimeter of said body portion.-

3. In a spanner for the free-wheel of a cycle or the like, a body portion having an opening therein, a conical member secured in said opening with itsbase portion projecting through said body to form aring or 'ange at one side of said body, andafpair of teeth formed at the base of said conical member adapted to enter recesses in the end face of a sleeve of a hub positioned in said conical member.
