HARRY RANDOLPH VAN DEVEN'IER, OF SUMTER, SOUTH CAROLINA, ASSIGrlllOlih TO I SPLITDORF ELECTRICAL COMPANY, OF NEWARK, NEW JERSEY, A CORPORATION OF NEW JERSEY.

To all whom it may concern:

Be it known that I, HARRY R. VAN Dn- VENTER, a citizen of the United States, residing at Sumter, South Carolina, in the county of Sumter and State-of South Carolina, has invented certain new and useful Improvements in Generator-Lamps, of

which the following is a specification, reference being -had to'the accompanying drawing.

My invention relates to generator lamps particularly designed for use on bicycles or the like.

The objects of the invention are to provide a simple and eflicient generator lamp in which all of the moving and more or less delicate parts are effectively housed and protected; also to provide a supporting device capable of holding the rotatable shaft of the lamp either in operative or inoperative relation'to' the vehicle wheel or other rotating part of the vehicle on'which the lamp is supported; also to provide a support which will permit the lamp to be adjusted so as to assure that theaXis of rotation of the rotating armature and its shaft lie in a'plane intersecting thezcenter of the wheel of the bicycle.

In the drawings, which show by way of illustration one embodiment of the invention:

Figure 1 is a side view showing my improved igniting and lighting device and'its relation to the bicycle;

Fig. 2 is a vertical sectional view through the same; and

Fig. 3 is a horizontal sectional view on the line 3-3 of 2..

Fig. 4 is an enlarged sectional view through the yielding device which holds the generating device in off position.

drawings.

Referring more in detail to drawings My improved generating and lighting device consists of a rotating armature 1, which is provided with the usual generating coil.

The armature has projecting from each end thereof, shaft sections, which together form the armature shaft, indicated at in the The armature 1 is mounted to rotate within the U-shaped magnet indicated at 3 in the drawings. Surrounding the magnet and the armature is an inclosing casing which consists of a body portion 4.- made from a single piece of sheet metal inter-' 1 with a flange 10, overlapping the body por- GENERATOR-LAMP.

provided with anintegral cup-like collar 7 inclosing a bearing 7 for the armature shaft 2 and a downwardly extending flange 8, which overlaps the body portion of the casing.

.At the lower end of the body portion 4 there is another end plate 9 which is formed tion of the casing and 'this end plate is formed with a cup-like collar 11 which incloses and carries a bearing 11 for thearmature shaft 2. The bearings 7 and 11 may be of any suitable ball bearing type. The shaft 2 projects below the bearing 11 and a driving wheel 12 is secured thereto by a set screw 13. The driving wheel has a projecting part 14 which is adapted to engage the tire or rim of the bicycle wheel for rotating the armature shaft. This driving wheel 12 is also formed with a projecting sleeve 15 which overlaps and completely houses the lower bearing 11-and prevents dirt and dust from getting into the bearing.

2 there is a sleeve 16 which is' secured to the shaft by a set screw 17. This sleeve is threaded to form a socket for the lamp 18. The sleeve 16 projects into a reflector indicated at 19 in the drawings. This reflector is firmly clamped to the casing of the generator and is provided with a sleeve 19 on its lower side fitting over the cup-like collar 7. The lamp is carried at the upper end of the sleeve and is located within the reflector. The end plates 6 and 9 are held on the body portion of the casing by a rod 20 which extends through the end plates and is provided with a nut 21 at one end thereof. Extendingthrough the end plates, 6 and 9 is a'supporting stud 21 which carries a lug 22 at its lower end and a nut .23 at its upper end. The casing is freely armature out of engagement with the wheel 1 5 .of the bicycle, it is held in this inoperative or oif position by'a yielding pin 25 carried" by a tubular arm 26 attached to the stud "21 and this yielding pin slips by the post 20l The pin 25 has a head 25 at its inneren'd 'll o Patented Oct. 23, 191 7.

' Application filed January 11, 1917. Serial No. 141,833.

On the upper end of the armature shaft -12 on the tire of the bicycle wheel.

' aeaaaee engaging an internal shoulder 26 at the bolt 29 and in turn is pivotally connected by a bolt 30 to the supporting bracket 31 attached to one member of the fork of the bicycle by uitable clamping arms 32, 32, and bolts 33, 33.

From the above description it will be ap parent that I have provided a generating and lighting .device consisting of few parts which are simple in construction and which are free from all loose connections and movable contacts, inasmuch as the lamp is carri'edl directly by the armature shaft and electrically connected to the coil on the armature shaft. The hearing at the lower end of the armature shaft is completely housed by the driving wheel. The casing surrounding the armature and the field magnet is of simple construction and easy to manufacture.

It will be seen that by turning the link 27- about. its bolt 30 and by turning the stud 21 about the pivot bolt 29, that the lamp may be moved toward and from the center of the bicycle wheel, which permits of positioningthe lamp for any size wheel without shifting the brackets 31, 32'. Furthermore, by swinging the stud 21 about the pivot 29, I am able to bring the axis of the armature into a vertical line passing through the axis of the bicycle wheel, and thus bring the armature shaft into a plane intersecting the center of said wheel, and so insure the free and easy running of the driving wheel Two adjustments may, therefore, be readily made, one, a shifting of the lamptoward and from the center of the wheel and the other a shift ing of the axis of the armature so as to bring it into a plane intersecting the center of the wheel.

It is obvious that minor changes in the details of construction and arrangement of parts may be made without departing from the spirit of the invention, as set forth in. the appended claims.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is
