UNITED vSTATES PATENT OFFICEQ GEORGE I-I. DAY, OF HARTFORD, CONNECTICUT, ASSIGNOR TO THE POPE MANUFACTURING COMPANY, OF PORTLAND, MAINE.

STEP FOR VELOCIPEDES.

SPECIFICATION forming part of Lettere: Patent No. 388,480, dated August 28, 1888.

lApplication led December S21, 1887. Serial No. 258,566. (No model.)

T0 LZZ whom, it Wray concern.-

Beit known that I, GEORGE H. DAY, of Hart ford, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Steps for Veloci pedes, of which the following is a specilication.

My improvements relate particularly to that class of steps known as adjustable steps,and principally used on bicycles, and are shown as applied in one form to the perch of a bicycle in the accompanying drawings, in which- Fignre 1 represents part of a perch and my improvements in perspective. Figs. 2 and 3 represent my improvements in detail and a part also in perspective. Fig. 4 shows in bottom plan my improvements assembled without the perch; and Fig. 5 represents the same in vertical transverse section on the line a: :v of Fig. 4, and Fig. 6 represents the same in vertical transverse section on the line y y of Fig. 4.

A is a perch.

B is my improved step attachment, which I prefer to strike out of sheet-steel, having the spring loop B and the two branches B2 B2 bored at B3 B3 for a bolt and at B4 BL for a pin or trunnion. I also prefer to make it with a part cut down on the top,as shown in the drawings, and with the back side of the loop narrower than the front,or,rather, with the braces b left on the front side. The middle of the loop can be left thin. Some of the weight is thus saved, elasticity increased, and the braces b b on the front side make a steadier and stronger bearing on the perch to resist the Weight of the riderin mounting.

C is a shoe-piece,which I prefer to construct with a broad slightly oval surface, notched or roughened with the small rasped teeth c c to prevent the shoe from slipping, and with the thin overhanging edges c c.

C2 is a lug projecting downward near the inner end of the shoe-piece and tubed to receive a bolt, and C3 is another lug,which serves as a trip for the ends of the branches B2B2 to rest against and also to carry the pin or trunnions E E.

D is a bolt; D', a nut.

In attaching my improved devices, I first place the attachment B on the perch or portion of the frame which is to suspend it by springing it over and upon the latter. I then place the shoe-piece upon the branches with the lug C2 between them, place the bolt D through the holes B3 B3 and the hole c2 in the lug C2, and start the nut upon the bolt, taking i care as the nut is tightened that the pin E E enters the holes B4 B4 in the branches B2 B2. It is obvious now that by leaving the bolt D slack the step can be moved vertically to any desired position, and that by setting up the 6o bolt the loop will be tightened about the perch and all the parts held securely in position together. It is also obvious that modifications in the details of construction may be made by any one skilled in the art While retaining the substance of my invention, and Ido not mean to limit myself to the precise things here shown and described.

I am aware that vertically-adj ustable velocipedesteps have heretofore been constructed, 7o and also that roughened shoe-pieces have heretofore been used, and I do not claim them.

I am also aware of a step constructed with a slit shoe-piece formed with a back plate or extended rest against the perch, and a spring loop Without, extended arms for the shoe-piece to rest on and a bolt and nut to secure them, so that pressure on the shoepiece tends to tip it about the bolt` and press the rigid heel of it against the perch, and I do not claim this; 8o but in my construction there is no heel or back rest to the shoe-piece, and the band or loop has extended arms on which the shoepiece rests,so that pressure on the shoe-piece,

'instead of presenting a rigid rest to the perch, 8 5

is taken by the arms and works a double grip of the elastic loop and openbraces b on the perch.

I claim as new and of my invention- 1. An improved adjustable Step and attach 9c ment,consisting in a spring-1oop and extended supporting arms and braces, a bolt and nut, and a shoe-piece resting upon the arms and secured by the bolt.

2. An improved adjustable step and attachment, consisting in a springloop and supporting-arms, a bolt and nut, and a shoe-piece resting upon the arms and secured by the bolt,and further secured bya lug and pin-trip between the arms. roo

velocipede-frame, as A, of a step attachment, 1o as B, a shoe-piece, as C, a bolt and nut, asD D', and a pin-trip, as E E G3, constructed to operate essentially as set forth.
