This invention relates to an improved and simplified unit or fixture for supporting certain instrumentalities ancillary to a bicycle or tricycle. The principal object is to provide an im- 5 proved unit and fixture of the class above mentioned. A further object is to provide a compartment structure, for instruments such as lights, audible signals and speedometers, which structure with the instruments mounted thereon,

will form a complete unit which is readily attachable to a handle bar or handle bar assembly of a cycle.

Another object is to provide a simple and effective supporting and housing structure for instruments ancillary to a cycle, which structure is so arranged as to permit ready accessibility to the interior thereof for service to, or replacement of, the instruments or parts of such, contained by the housing.

Further objects include the provision of an im proved speedometer mounting, an improved lighting fixture, and an improved audible signal for cycles.

Other objects and features of the invention will become apparent from the following description, relating to the accompanying drawings,

showing the preferred form. The essential characteristics are summarized in the claims.

In the drawings, Fig. 1 is a perspective view of a. handle bar unit incorporating the present invention; Fig. 2 is a central, longitudinal sectional View of the combined unit or fixture showing its mounting on the handle bar and post; Fig. 3 is a transverse sectional view, as indicated by the line 3-3 on Fig. 2; Fig. 4 is a central sectional view, similar to Fig. 2, but with the upper portion of the compartment structure swung toa position rendering the interior accessible; Fig. 5 is a sectional plan view of the structure as shown in Fig. 4, the sectional portion of the View being taken as indicated at 55 on Fig. 4; Fig. 6 is a plan view of a mounting bracket for securing the compartment structure to the handle bar post, and Fig. 7 is a sectional plan view of the preferred light socket and mounting, as indicated at 7-! on Fig. 5.

Referring first to Figs. 1 and 2, a handle bar of a common type, is shown at l. The particular bar shown is for bicycles, and has the usual handle grips 2. 3 indicates a substantially straight horizontal central portion of the bar. Said horizontal portion is secured to a handle bar post 5, through the intermediary of a forwardly extending arm 6 of the post, having a s5 cylindrically formed recess 7, on its lower side.

The recess embraces the central portion of the handle bar as shown at 8, and the latter is held in adjusted position as by a clamping screw 9. The post 5 extends downwardly into the usual head cluster (not shown) of the cycle frame, and is attached to the front or steering fork, (not shown) by means of a screw or bolt having a head, such as indicated at 10. The handle bar and post comprise the handle bar assembly.

The compartment structure comprises a bottom member or base 12 and a top member or cap 40. The base, which is preferably made of sheet-metal, extends from the horizontal portion 3 of the handle bar, rearwardly over the post, and in spaced relation to it, as shown in.-

Figs. 2 and 4. The base is generally heartshaped, and its forward end portion is formed with one or more supporting arm portions, two being shown at 15, which are cylindrically concave on their lower sides, so as snugly to clasp the upper surface of the handle bar for support. The rearward end is supported by a curved bracket [6, having a flanged body portion l'l (actually 0 shaped) and flat end portions. The lower fiat end l8 rests on top of the post and is secured to it by the cap screw or bolt which has the head Ill. The upper end of the bracket [6 underlies a downwardly depressed portion IS on the base l2. The bracket may be secured only at the central opening shown at 20, in Fig. 6, which receives the hollow driving shaft stud of a speedometer, S, to be later described more in detail. However, the bracket [6, as shown, has laterally extending arms 2| underlying the side portions of the rear of the base, and these lateral extensions preferably form the main rearward support for the base I2. Attaching devices, such as bolts or screws 22 enter openings positioned as shown in Fig. 5 to couple the bracket 16 and the base. Preferably the screws extend upwardly from the base for detachably securing the rear portion of the cap. Such screws or securing devices enter suitable threaded apertures on the bottom surface of the cap and may make quick detachable connection therewith (not shown), but which may be made like an ordinary bayonet lock.

The base may have strengthening flanges 23 on its sides, lateral extensions 24 of which serve as abutments for the bottom side of the cap, so that when the cap is attached in operating position, it holds the forwardly extending arms l5 snugly against the handle bar. The rear portion of the base also has a diagonally upwardly extending flange efiect at 25, Figs. 2, 4 and 5. This partially surrounds the speedometer instrument S.

The speedometer may be of any suitable type. As shown, it has a body 26 which rests on the diagonally downwardly extending portion l9 of the base (or it may rest only on the portion l9 of the bracket l6). A dial is indicated at 21. Such speedometer is usually equipped with a threaded hollow extension, such as indicated at 28; reduced therebelow for connection with the usual driving cable assembly. This threaded extension carries a nut 29, which clamps the body 26 and the base stamping against the bracket portion I9, thereby firmly securing the speedometer in place and also additionally securing the base to the handle bar post.

A suitable audible signal or resonator assembly 30 of a known type, is mounted over a flanged opening 3| in the base, as on a diagonally extending bracket 32, having downwardly turned ends 33, which are attached to the base, as by suitable bolts or screws at 34. This has an electro-magnetically operated diaphragm on its underside facing the opening 3|, so that the sound generated by the resonator passes out freely.

On opposite sides of the resonator and speedometer, suitable cradle-like battery holders 35 of sheet metal are shown as carrying batteries B and B. These holders may be of any form and attached to the base so that the batteries can be put in from the top side. Contact members 36 and 31, which spring against opposite pole projections or surfaces of the batteries, complete the battery holding arrangement.

It may be mentioned that instead of having the batteries accessible from the top side of the base, these may occupy -suitable downwardly facing recesses in the base, bridged by any suitable arrangement, or closure, to hold them in. Also,

the batteriesmight be secured to the cap All, in a 'manner'similar to that illustrated in Fig. 5. Since such modification would necessitate only a rearrangement of the conductor wires and fasteners, it is not illustrated. The resonator may likewise be fastened on the cap 40 instead of on the base.

Referring further to the cap or top member 40, this is preferablyformed as a die-casting. It will be seen from Fig. 1 that the cap is generally arch shaped' at its central portion, so as to provide adequate space beneath it for the instruments mentioned, including the speedometer which is exposed through an upwardly facing opening 4| in the cap. The cap, as shown is in general accordance with my copending design patent application, Serial No. D-64,878, filed September 16, 1936. It may also be like the design of my application D-64,879 filed concurrently therewith, showing a single lamp.

The cap may have generally bullet-shaped, hollow side portions 42, the forward ends of which are open to expose the light through suitable lenses '45 mounted inside the cap, in suitable sockets.

For attachment to the base (through the intermediary of the handle bar) the side walls 44 of the cap 40 have circularly formed downwardly facing slots or recesses 46, which are in straddling relation to the forwardly extending arms l5 of the base, and which snugly embrace the handle bar portion 3 at each side of the base. These downwardly recessed side portions of the cap are connected pivotallywith the handle bar portion 3, by curved clamping plates 41, each of which may be secured at one or both ends of the cap. As

'ately insulated from the base.

shown, there is a single attaching screw 48 for each clamp, passing upwardly into suitable bosses on respective side walls 44. Since the base is eifectively secured to the handle bar assembly so as to comprise a unit therewith, it will be seen that the top member is, in efieet, pivotally secured both to the base and to the handle bar. This pivoted arrangement and detachable securing means for the cap, already described, permits the cap to be swung upwardly substantially into the position shown in Fig. 4, wherein a central depending portion 4'! of the cap contacts with the lower surface of the arm 6 of the handle bar post and forms a stop.

The lighting fixtures include, as shown, particularly in Figs. 5 and 7, reflector members 50, which receive the shanks 5| of the bulb, and make electrical contact therewith. The reflectors are dome-shaped shells, the outer margins of which lie in socket formations formed at the outer H margins of the lenses.

lenses, and this, as shown, comprises detachable spring strips 54, the central portions. of which contact with the electric-contact-projections of the bulbs and the end portions of which are sprung to underlie oppositely positioned lugs 55, formed within the cap.

The cap ll] preferably supports a suitable switch 60 (Fig. 5) for the lights. The operating arm 58 of such switch passes through a suitable opening 51 in the cap. The body of the switch is secured on the underside of the cap, as by suitable oppositely positioned rivets. The light switch may occupy any other position on the cap, and moreover, may be mounted on one of the handle bar arms in accordance with the description of such a switch mounting given below.

Since it is desirable that the audible signal control be located close to one of the handle grips, for quick accessibility by the user of the cycle, the arrangement includes a switch device 6|, having a suitable hollow housing with an annular supporting base 62 embracing the handle bar. An operating button 63 extends from the top of the switch. The handle bar, as usual, is hollow, and the terminal wires of the switch pass into a lateral opening 64 in the bar, and thence along the bar to an opening 65 near the handle bar post. In Fig. 5 the two wires from the switch 6| (indicated at 10 and 7|) are seen to pass out of the opening 65 and thence to respective binding devices 12 and 13 on the base and signal 30, respectively. The binding device 12 is appropri- With further ref erence to Fig. 5, it will be seen that the signal 39 is operated when the circuit, including the conductors l0 and II is closed, by reason of the fact that both the batteries B and the signal are grounded to the base, the conductor 13 being connected to one terminal of the battery assembly, by means of a flexible conductor 74, connecting the contact 36 with the binding device 12.

The connections between the lights, light switch and the batteries B incldde, as shown, flexible conductors l5 and 16, which may be soldered to the insulated reflector members 50 and similarly connected to one side of the switch 60. A third flexible conductor Tl leads from the other side of the switch down to a binding device 14,

which is inturn electrically connected with the battery unit B, as by a short conductor wire 18. The binding device 14 is insulated from the base and all of the devices l2, l3 and 14 are preferably of the spring clamping type, readily releasable by the human fingers.

It will be seen that there is no necessity for disconnecting any of the flexible connections, when the cap is swung upwardly to the position shown in Fig. 4. Such opening of the compartment structure permits access to the batteries, inspection of the audible signal and ready removal and replacement of the light bulbs. Removal and replacement of the batteries is simply a matter of slipping them out of the holder and putting new ones in place.

Removal of the light bulbs is simply a matter of taking out the spring strips 54, and the refiectors, replacing the bulbs and re-inserting the reflectors and strips. It will be noted that notwithstanding the compactness of instrument arrangement in the compartment structure, there is no danger of shortening of electrical connections. If it is desired to remove the cap entirely from the base and handle bar this may be done simply by releasing the spring connectors 'l2l4 and removing the clamping plates 41.

It may be mentioned that when a speedometer mechanism is not desired or is not present on a cycle to which the fixture is to be applied, then the top opening 4| is closed by a dummy dial containing appropriate decorations. This may be sprung into place in the speedometer dial opening in the cap, or otherwise suitably secured.

The expression handle bar assembly as used herein shall be interpreted to describe a handle bar and support or post, whether made in two or more parts, say as shown, or as one integral part.

I claim:

1. A fixture to be mounted upon the handle bar of a cycle, comprising a compartment structure adapted to carry instruments ancillary to a cycle, said structure comprising a top member and a bottom member hinged together substantially on the axis of the handle bar, and means detachably connecting the two members in a region remote from the hinge axis to permit one of the members to be swung open relative to the other member, whereby access to the compartment is afforded.

2.
