The-length off the stud-1 20 is sli'ghflly' i which arch is semicircular in cros's-section,'

bifurcated plate, so that a close fit of the parts is maintained.

Cooperating with the clamping element or plate 11L is a second element comprising an arch 25, from one end of which is an extension 26 in alinement with the diameter of the arch,

said extension 26 having a perforation in .alinement with a similar perforation in the extensionlii of the, major element of the clamp, and through which perforations is passed a clamping-bolt 27, provided with a nut 28.

In order to provide a pivotal connection between theiclamping element, comprising the arch 25, "and the major element 1-1, I form a slot- 29 in the latter adjacent the lower end begunderstood that they may have any desired shape to adaptthem for close contact withjany body upon which it maybe desired tofit them.

"plying-my device to a bicycle the clamping elelnen-ts are engaged with the tie-rod of the frame on theside next the chain with the minor element upon the-outer side of the tierod-that is, in this specific shape of clamp with theoutwardly extending portion of the.- major element projecting outwardly from the bicycledframe aud beyond the plane of the chain. The bifurcated plate is then adjusted to cause the brushes to lie on opposite sides above and below the chain, the clamping device'bein'g moved to'that position on the tierodto eftect thi's'resnlt when the major element of the clamp 'is in its pivotal engagement with the bifurcated plate. The nut 28 is thenturned "up to hold the device firmly in position. Thus it will be seen that because of the shapes of the-stud 20 and opening 18 the bifurcated plate, and therewith the brushes, will have a free "vertical swinging movement limited only by the. chain, and thus as the chain is thrownve'rtic'al the brushes will maintain" their contacttherewith and their effectiveness} i It will be readily understood that I may employ any shape or style of brush, that I may employ any desired material for the different parts of the construction, and that in practachment to a bicycle, the combination with a clamp, of a bifurcated plate having arms equal in length and rigid with respect to each other, said plate being rotatably mounted upon the clamp, the ends of the bifurcations being bent upon themselves to form brushholding clamps; brushes mounted in the clamps and in axial alinement, and means for operating the clamps ,to hold the brushes adjustably. v l

2; In a bicycle-chain cleaner adapted for attachment to a bicycle, the combination with a clamp, of a bifurcated plate mounted rota- -tably upon the clamp at the rear of the bifurcations and having arms which are equal in length and rigid with respect to each other, said arms having their outer ends bent to form brush-holding clamps, br'ushesdisposed .v in the clamps in axial alinement andproject- As shown in Fig.- 2 of the drawings, in tip iug toward each other, and, means for operating the clamps to hold the brushes adj usted to play in ."saidannnlar opening. and pro-- vided with a iveb adapted to pass through the keyhole-slot, the bifurcations of the plate being equal in length and having their'ends bent upon themselves to form clamps, brushes mounted in the clamps in axial alinement and projecting toward each other, and means for operating the clamp to hold the brushesad justably.
