BAND FOR PERSONAL WEAR Application filed May 2a, 1929. Serial m. 386,626.
This invention relates to an improved construction and method of forming a strap,
band or chain, which may be used for personal wear such as a bracelet, belt or the like; and has for its object to provide a strap or band of this character formed of flexlble material having short tubular sections secured along opposite edges thereof to serve as an ornamental binding for these edges,
A further object of the invention 1s to form a series of short tubular sections from a length of tubing which is circumferentially grooved at close intervals and slotted on one side along its length to receive and grip the edges of the strip, the sections bemg broken apart at the grooves after the length of tubing has been applied to the strap,
The invention further consists 1n formlng the abutting ends of the short sections beveled outwardl from each other to facilitate the flexing o the strip or band.
With these and other objects 1n view, the invention consists of certaln novel features of construction, as will be more fully described, and particularly pointed out in the appended claims.
In the accompanying drawmgs:
Fig. 1 is a face view of a short length of flexible strip to which my improved tubular binding edge members are applied.
Fig. 2 shows the strip of flexible material as grooved along its edges and one tubular strip of edge binder being slid endways onto the edge of the strip.
Fig. 3 is an enlarged end sectlon of the tubing before it is split.
Fig. 4 is a side elevation showing a short section of this tubing circumferentially grooved at intervals along its length by rol1- ing the surface stock inwardly over the base metal body portion thereof.
Fig. 5 is a section of the member illustrated in Fig. 4.
Fig. 6 is an end View showing the slot in the tubing with the 1 reduced portion in section where the short sections of tubing are broken from the longer length thereof.
Fi leng i of tubing showing the same slotted along its length.
is a perspective yiew of a short Fig. 8 shows these tubular sections as applied to opposite ed es of a stri of flexible material with its e ges embed ed into the material.
It is found in practice of advantage to be able to bind the opposite edges of a strip of flexible material which may be employed as a bracelet, band or for other purposes, by preparing a length of tubing to be attached to the edge of the strip by forming spaced circumferential grooves at intervals along the length of the tubing thus reducing its cross sections to be easily broken at these points, the tubing being herein shown slightly greater in diameter than the thickness of the strip to which it is applied. I then slot the tubing along its length and insert the edge of the strip into the slot of the tube, and then by compressing the tube these edges are caused to grip the strip and so become permanently secured thereto. I then flex or otherwise break the stock of the tube at its grooves which particular construction has a number among others being that by rolling the outer surface of the stock inwardly on an angle the surface of precious metal the base metal at the ends of the short tubular sections; then again these end portions are thus made very smooth so as not to abrade the flesh of the wearer when it comes in direct contact therewith, which is not the case if these grooves were cut by a sharp instru ment. Also by rolling or compressing this stock, the same is reduced very materially rendering it easily broken at the grooves after the length of tubing has been applied to the edges of the strip.
In some instances it is found of advantage to groove the strip longitudinally adjacent its opposite edges and compress the tube so that its edges will engage this groove and be more securely fastened to the strip; and the following is a detailed description of the 1s turned over present embodiment of my invention and showing one construction of strip or band by which these advantageous results may be accomplished.
With reference to the drawings, nates the body strip of any suitable such as textile fabric, leather, woven 10 desigmaterial, wire fabric,
or other material, into the surface of which I preferably form a lon itudlnal groove as at 11, adjacent to or space slightly inwardly from its opposite edges 12. then prepare a length of tubing 13 by rolling or swaging annular grooves 14 at close intervals along thelength of the tube and the tube is then slotted longitudinally as at 15 along its length, the slot being of a width to receive the strip or the grooved portion of the stamp and be threaded thereonto, as best lllust'rated in Fig. 2, after which pressure is brou ht to bear upon the tube closingits edges to flrmly grip the strip or the walls of the grooves 1n the strip.
The strip with these lengths of tubm secured thereon is then flexed and the tu ing broken at each of its grooves.
It will be noted that by forming these grooves 14 on an incline I obtain a number of advantages: First, when plated material is employed I roll the outer coatlng of plating of precious metal inwardly over the base metalportion so that the latter is not exposed; second, by beveling the abutting edges of the tubular sections the strap or strip is rendered much more flexible than where the abutting edges are square and not beveled; and thlrd, by rollin these rooves into the tubmg no :ough or eathered edges are formed to abrade the flesh of the wearer.
My improved strap with the binding or edge members thereon is very handsome and attractive in appearance, is smooth to the touch and is strong and durable and by my improved method of attaching the binding members to the strip or band the same is rendered very flexible.
The foregoing description is directed solely towards the construction illustrated, but I desire it to be understood that I reserve the privilege of resorting to all the mechanical changes to which the device is susceptible,
the invention being defined and limited only by the terms of the appended claims.
1. A method of forming a strap, which consists in forming spaced circumferential grooves at intervals along a length-of tubing of a diameter slightly greater than the thickness of the strap to which it is applied, slotting the tube along its length, inserting the edge of the strap into said slot of the tube, compressing the tube to grip the strap and breaking the stock of the tube at the grooves.
2. A method of forming a strap, which consists in longitudinally grooving the strap adjacent its opposite edges, pressing circumferential grooves in spaced relation along a length of tubing, slotting the tube on one side along its length and inserting the opposite edges of the strap each into the slot of a length of tubing, and compressing both tubes to grip the strap along its grooves and breaking the tubes apart'at its grooves.
sists in forming spaced circumferential grooves at intervals along a length of tubing plated on its outer surface with precious metal and of a diameter slightly greater than the thickness of the strap to which it is applied, slotting the tube along its length, inserting the edge of the strapinto said slot of the tube, compressing the tube to grip the strap and breaking the stock of the tube at the grooves.
6. A method of forming a strap, which consists in longitudinally grooving the strap adjacent its opposite edges, presslng circumferential grooves spaced along a length of tubing plated on its outer surface with a precious metal, slotting the tube on one side along its length and inserting the opposite edges of the strap each into the slot of a length of tubing, and compressing both tubes to grip the strap along its grooves and breaking the tubes apart at its grooves.
In testimony whereof I afiix m si nature.
