SPECIFICATION forming part of Letters Patent No. 575,779, dated January 26, 1897'.
Application led December 8, 1896. Serial No. 614,872. (No model.)
To all whom. t 712/14/ concer/L.
Be it known that I, WILLIAM C. HoMAN, a citizen of the United States', residing at Meriden, New Haven county, Connecticut, have invented certain new and useful Improvements in Bicycle-Lamp Brackets, of which the following is a full, clear, and exact specific-ation.
My invention relates to improvements in lamp brackets or supports,particularly useful for the purpose of connecting a lamp to the frame of a bicycle or other vehicle; and it consists, primarily, in improving the clamping members of said bracket.
The object of my invention is to provide a simple and effective means for accomplishing the desired end, which means may be easily and quickly attached to the vehicle at desirable points, and by which means the lamp may be readily adjusted at any desired angle. j
My invention is illustrated by the accompanying drawings, in which- Figure l is a plan view of the forward portion of a bicycle, showing a lamp and bracket support in one of the operative positions, the clamping members being illustrated in a p0- sition to engage a rounded portion of the bicycle-frame. Fig. 2 is a relatively enlarged plan view of the bracket-support shown in Fig. l, the clamping members of said bracket being illustrated in a position adapted to engage an angular portion of the bicycle-frame, such as, for instance, the fork of a bicycleframe. Fig. 3 is a side elevation of Fig.
Similar letters refer to similar parts.
A is the front frame tube or head of a bicycle-frame. This head portion, as illustrated, presents a rounded surface.
B B are blades of the front fork of abicycle. Each of these blades, as illustrated, have a somewhat angularsurface. The clamping members of the lamp-bracket illustrated are adapted to engage either the said rounded surface of the head portion A or the somewhat angular surface of the fork-blades B B.
D is alamp. E is a rearward projection from said lamp, said projection affording one of the means, for adjustably connecting said lamp to the clamping members of the bracket.
F F are the main clamping members of my improved bracket. The clamping members F F are pivotally'mounted at one end of the bracket. The opposite ends of the said clamping members F F are provided on their inner faces with curved or rounded depressions, corresponding substantially to a'curved or rounded portion of the frame to which it is desired to attach said bracket, such as, for instance, the tubular head portion A of a bicycle.
G is a suitable bolt for operating said clamping members F F.
G' is an adjustingnut for drawing the clamping members into close engagement with the desired portion lof the bicycle-frame. The bolt G is provided with a suitable head, the head shown being` formed by upsetting one end of said bolt and forming substantially an eye.
H is the bolt which forms the pivotal connection for the ends of the clamping-arms F F. This bolt is provided with a suitable adjusting-nut H'. Pivotally mounted upon said bolt H is an arm I. One of the lateral faces of said arm I is preferably roughened or knurled, as shown at I. Against the surface of the said arm I the extension E from the lamp is adapted to bear when in operative position. The surfaces of the said extension E are also preferably roughened or knurled,
J is a bolt, and .I' is a nut thereon, by means of which the parts I E may be fixedly held in firm engagement.
The device thus far described is specially adapted to be attached to a rounded portion of the frame of a bicycle or other vehicle. In the position shown in Fig. 1 the clamping members project laterally from the head A, and in order that the rays of light from the said lamp may be projected into the path of travel of said vehicle the pivotally-supported arm I is turned at a suitable angle to said clamping-arm, as shown, and then set by means of the nut H'. To this arm I is attached the lamp D, the vertical adjustment of the lamp being readily permit-ted by loosening the nut J' and tipping the lamp into the desired position where it may be set by tightening the nut J.
When it is desired to attach the device to an angular body, such as, for instance, one of the front-fork blades B, I make use of supple- IOO mental clamping-arms K K, suitably mounted on the free extremities of the clamping members F F, so that when said supplemental arms K K are set in the position indicated in Fig. 2 the bracket may be securely attached to an angular body.
The supplemental arms K K are provided with angular recesses or depressions, as shown, so that when the parts are in the position shown in Fig. 2 the inside of the forkblade B is engaged by the clamping members F F, as shown, and the outside of the said fork-blade is engaged by that portion of the supplemental arms KK inside the circle determined by the rounded depressions in the clamping-arms F F. By preference these suppleinental arms K K are pivotally connected, as at I. L, and are provided with asuitable stop to engage them in either of the positions shown in Figs. l and 2. One means for cheeking said supplemental clamping-arms in the position shown in Fig. 2 comprises a connection K between each set of arms K K, the inner edge of which connection bears against the inner face of the clamping-arm F. One means for holding the supplemental arms K K in the position shown in Fig. 1 comprises one or more ears K2 on each set of supplemental armsrK K. \Vhen the parts are in the position shown in Fig. l, the tube A projects into the arc in which the projections K2 must necessarily move in order to permit the said supplemental arms K to be turned in one direction, while the connection K', resting against the outer surface of the clamping members F F, prevents said arms from turning in the other direction. By thesemeans the supplemental clamping-arms K K are securely held in either of the positions illustrated and prevented from rattling, which is au undesirable feature which must be guarded against in devices of this character.
M M are slots in the opposite sides oi' the clamping members F F. These slots are of sufficient width to admit the bolt G to be shifted from the position indicated in Fig. l tothe position indicated in Figs. 2 and 3, one of the advantages ot' the shifting of the bolt being the desirability of having the means by which the clamping members are drawn together as near the body, to which the clamping members are adapted to be attached, as possible. Suitable depressions N N may be provided in opposite sides of either or both of the slots M as a means for preventing the bolt Gand nut G from accidentally slipping in said slot.
1. In a lamp-bracket for the purpose described, main clamping-arms having depressions adapted to engage the vehicle-frame, supplemental arms on said clamping-arms provided with suitable depressions, said snpplemental arms being adapted to be turned so as to project into the space between the depressions in the main arms.
2. In a lamp-bracket for the purpose dcscribed, main clamping-arms provided with curved depressions adapted to engage rounded surfaces,adj ustable supplemental arms at the extremities of said main. clamping-arms, angular depressions in said supplemental arms adapted to engage the surfaces of angular bodies when said supplemental arms are turned to project into the space between the curved depression in the main clamping-arms.
In a lamp-bracket for the purpose dcscribed, main clamping-arms provided toward one end with curved depressions, supplemental arms pivoted to said main clampingarms, angular depressions in said supplemental arms,whieh,when the latter are turned so as to project into the space between the depressions in the main arms, are presented for engagement with surfaces of angular bodies, and means for drawing together said clamping members.
4. In a lamp-bracket for the purpose described, main clamping-arms, supplemental clamping-arms pivotally connected thereto, connections K between each set of supplemental clamping-arms, said main clampingarm and supplemental clamping-arm coperating to engage an angular body, when the latter are turned so as to project into the space between said main clamping-arms.
5. In a lamp-bracket for the purpose described, main clamping-arms, supplemental clamping-arms pivotally connected thereto, connections K between each set of supplemental arms and ears K2, substantially as and for the purpose described.
G. In a lamp-bracket for the purpose dcscribed, main clamping-arms, and supplemental internally-acting clamping-arms pivoted thereto, means for operatin g said clamping members and an extension I, pivotally mounted on the bolt II, and means for adj ustablyl holding said extension I in the desired position.
7. In a lamp-bracket for the purpose described, main clamping-arms pivotally connected at II, supplemental clamping-arms pivotally connected at the free ends of said main clam pin g-arms, depressions in said snpplemental clamping arms, said clamping members coperating to engage either rounded or angular surfaces, means for drawing said clamping members toward each other, and means for attaching said bracket to the body of a lamp, substantially as described.
