SPECIFICATION forming part of Letters Patent No. 593,016, dated November 2, 1897.

Application filed May 22, 1896 Serial No. 592,645. (No modeld To (LZZ whom it may concern.-

Be it known that I, GEORGE HAVELL, a citizen of the United States, residing at Newark, county of Essex, State of New Jersey, have invented certain new and useful Improvements in Bicycle-Lamps, fully described and represented in the following specification and the accompanying drawings, forming a part of the same.

The object of the present invention is to reduce the number of pieces,and thus to cheapen the constructionof a bicycle-lamp formed of sheet metal. To accomplish this object, I form the body with a central globe having a collar at the bottom to attach the oil-cup and a flaring funnel at the top, and I form such body wholly of two pieces by dividing the body in the process of manufacture vertically upon the center line of the collar and funnel. By this construction the opposite halves may be struck in the same die, as the height of the globe, funnel, and collar is obviously the same upon each of the halves, and the central portion of the globe is easily perforated upon one of the two parts to form the aperture upon which the lens is secured. Such aperture is formed by stamping a circular piece or segment from the middle of the globe upon one of the parts, a bead being then turned upon the edge of the aperture to strengthen the same and form a means of attachment for the lens-ring. By forming the aperture and the bead wholly on one of the parts I make the bead integral throughout its entire periphery, and thus make it much smoother and stronger than if it were divided by a vertical or horizontal joint.

In dividing the lamp-body at the opposite sides I intersect the bezels in which the sidelight jewels are secured, and I therefore form each of the body parts with a half-collar having a semiseries of tongues attached thereto, the collars and tongues, when the two parts of the body are united, serving, respectively, to support the back of the bezel and to bend over the front of the same. With this construction each half of the body, including the bezels, is readily stamped from a single blank of suitable form. p The invention will be understood by reference to the annexed drawings, in which- Figure 1 is a side view of the bicycle-lamp with the lens and its collar in section. Fig. 2 is a front view of the lamp-body and oil-cup with the body in section upon line 2 2 in Fig. 1 and the jewel omitted from the righthand bezel. Fig. 3 is a plan of the oil-cup with the collar upon the body in section and shown in solid black. Fig. at is a plan of the socket upon the top of the oil-cup to receive. the collar B B. Fig.5 is a perspective view of the band which forms the catch for the oil-cup. Fig. 6 is a section of the body on line 6 6 in Figs. 1 and 2, showing the shape of the flanges upon the two parts of the body to form the vertical front seam; and Fig. 7 is a similar section with the seam closed. Fig. 8 is a view of the inner side of the ring for the lens. Fig. 9 is a plan of the funnel-cap. Fig. 10 is a plan of the top of the funnel, and Fig. 11 is a cross-section of the collar at the bottom of the body with vertical folded seam like that shown in Fig. 7.

A A design ate the front and rear halves of the body.

B B are the two halves of a collar, formed integral with the'body at its lower end to receive'the oil-cup.

G O are the two halves of the funnel, formed integral with the body at its upper end. The front and rear parts of the body are shown in Fig. 6 provided, respectively, with the bent flange a and the straight flange ta which, as they form a straight joint between the two parts of the body, can be simultaneously closed in a single pressing operation to form the vertical standing seam a. Such standing seam can be readily formed (without supporting the parts intern ally) by dies adapted to fold the flange a over the flange a as is clearly shown in Fig. 11. By such method of closing the joint I avoid the necessity of supporting the parts internally, although I am able to produce thus only a seam which pro jects radially from the body throughout the entire length of the joint; but such radiallyprojecting seam is especially adapted to form a rib upon opposite sides of the supportingcollar 13 B, which, when notched, cooperates with a catch upon the socket of the oil-cup. The seam is shown intersected upon the middle of the body by the bezel, which is formed integral with the sheet metal of the body, the parts A A being .formed each with a semicollar (9 and with a semiseries of tongues 1), (shown at the right-hand side'of Fig. 2,) the collar and tongues being adapted to support edge of the aperture and provided upon op posite sides with notches 'e,.and the lens F is shown secured in a collar f, having an annular recess f to fit over the bead e and two tongues f which engage the back of the bead, except when turned opposite the notches .6, to detach the lens and collar in the usual,

holes 0 to prevent the direct access of airdrafts, and the lower edge of the bell is curved face, and thus avoid the special construction 1 of dies which is required in stamping upon} a convex surface.

The seams upon opposite sides of the col- 1 lar B 13 form vertical ribs, which are provided with n otches a to cooperate with a catch upon the oil-cup. To furnish such a catch, the oilcup is provided with a socket E, attached to the top of the oil-cup by a flange D, soldered thereto, and is furnished upon the opposite sides with loops E, adapted to fit over the notched ribs a, The loops E are formed with notches E (marked at the left side of Fig. 2,) corresponding with the notches a in the ribs, and a band g of the same width as the notches is fitted to the exterior of the socket E and provided with loops g, which correspond ex- The top C and tube c are formed. integral with the funnel O 0, so that each half of the lamp-body is in one piece from the I The band is formed with a thumb-piece t to rotate it upon the socket and with a stoppin h, which projects above and below one of the loops 9 to contact with the loops E when the loops are coincident, as shown in the dotted lines h and 2 upon the lower side of Fig.

' 3. The stop it and the thumb-piece t' are shown in full lines upon the upper side of Fig. 3, indicating the position in which the band is turned to lock the oil-cup to the collar B B by shifting the cylindrical or body portion of the band g into the notches a, as shown in Fig. 2. When thus shifted, the band fits between the upper and lower portions of the loops E and is thus held from displacement,

and it is also held in place at other portions of its periphery by teeth t, stamped outwardly from the metal of the socket at the upper and lower edges of the band. The collar B B is V 5 formed with a notch j to pass over the spindle The funnel is flared or expanded toward? the top 0 to furnish area around its outer: edge fora sufficient number of vent-holes c. (Shown in Fig. 10.) The top is furnished; with a central tube 0, projected upward to support the cap, which is provided with a;- round flat seat d in the center to rest upon is, which is used for adjusting the lamp-wick, and the top of the socket is cutout for one quadrant of its periphery, as shown in Figs. 1 and 2, down to the top of the band 9 to permit a partial rotation of the wick-tube and its clamping devices with the spindle 7t to detach the wick-tube from the oil-cup when necessary to fill the cup with oil.

It will be observed by comparing the position of the thumbpiece t' in full lines and dotted lines in Fig. 3 that the band may bee 1 turned nearly a semirotation upon the socket The seat 61 has a cylindrical border d from which a bell d is projected downward, anda series of holes 0 (shown in Fig. 9) is formed? The bell is solid in a line with the holes 0, and the 1 top 0 is in like manner solid beneath the.

E'when locking the oil-cup to the lamp-body, and such an extended movement of the catch wholly precludes the possibility of an accidental displacement or disengagement of the catch, and the oil-cup is thus fastened to the lamp-body most securely.

A sliding catch adapted to engage the notched ribs upon the collarof the lamp-body is much more durable and presents ilarger wearing-surfaces than the spring-catches, which snap into a hole or against a shoulder automatically and which depend chiefly upon the resilience of the spring for. their engagement. I have therefore claimed a sliding catch for engaging with such notched rib.

By dividing the body into opposite halves vertically and connecting the parts by a folded scam the seam furnishes a convenient rib upon the collar at the bottom to constitute a portion of the locking device.

I hereby disclaim the application filedJuly 18,, 1896, with Serial No. 599,598, by G. I-Iavell and A. H. Meyer for patent on bicycle-lamps, and do not claim, broadly, the bead, (lettered e in my drawings,) as the same is shown and claimed in the said application.

. Having thus set forth the nature of my invention, what I claim herein is- 1. A bicycle-lamp having aglobe, with funnel upon the top and oil-cup uponthe bottom, and divided vertically upon the center line, with the two parts formed of .sheet metal and united by a vertical standingseam projected radially from the exterior of the joint, and the seam notched transversely at the opposite sides of the collar to engage a lock upon the oil-cup, as and for the purpose set forth.

2. In a bicycle-lamp, the combination, with the globe A, A, and the collar B, B provided with the notched ribs a at the opposite sides, of the oil-cup D carrying the socket E to'fit the collar and provided With notched loops E to fit over said ribs, and a sliding catch movable upon the socket in the notches of the loops to engage the notches in the ribs, as and for the purpose setforth.

3. In a bicycle-lamp, the combination of a collar at the bottom provided with notched ribs at opposite sides, an oil-cup having a socket to fit the collar and provided with notched loops to fit over the said ribs, and an annular band fitted to rotate in the notches of the said loops and provided with corre sponding' loops, and with means for rotating the band to look the socket upon the collar, substantially as herein set forth.

In a bicycle-lamp, the combination, with the globe'A, A, and collar B B provided with the notched ribs a at opposite sides, of the funnel having the integral top (J curved in- Wardly and provided with the central tube 0, of the cap having the flat seat d fitted to the top of such tube and provided with the bell d extended downward over the cover, and the cap and cover being perforated, as and for the purpose set forth.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses. o

GEORGE HAVELL. Witnesses:
