0. MASGHMEYER. METAL TUBING Patented July 15, 1890. I
UNITED STATES PATENT OFFICE.
CHARLES MASCHMEYER, OF MERIDEN, CONNECTICUT, ASSIGNOR TO THE EDWARD MILLER & COMPANY, OF SAME PLACE.
METAL TUBING.
SPECIFICATION forming part of Letters Patent No. 432,059, dated July 15, 1890.
Application filed May 23, 1890. Serial No. 352,954- (No model.)
To (tZZ whom it may concern.-
Be it known that I, CHARLES MASCHMEYER, a citizen of the United States, residing at Meriden, New Haven county, Connecticut, have inventedanew and useful Improvement in Metal Tubing, of which the following is a specification.
Myinvention is intended to produce a tubing similar to the embossed or fancy-pat tern, metal tubing now used in chandelierwork and the like at a less cost, or a tube bearing a pattern superior in sharpness of outline to what can be economically produced by the usual methods. In the accompanying drawings, Figure 1 represents in elevation a piece of tubing partly covered. Fig. 2, also in elevation, shows a modification. Fig. 3 is a section of a modified detail.
The same letters refer to like parts in the several views.
A designates a tube; 15, a strip or ribbon of metal.
Heretofore it has been customary to pro- 2 5 duce an embossed pattern on tubing by passing a plain tube between rolls or under an indenting-tool. This and similar methods can 'be employed only on tubing of a thickness varying within narrow limits, as if too thick it cannot be readily indented; if too thin, it
cannot withstand the crushing pressure. Besides this, it is often desirable, especially where it is necessary to telescope one tube within another, that the inner surface of the tube should be smooth, while its exterior is ornamentally corrugated or indented.
My invention secures the production of a tube of any desired thickness, smooth on its interior, and ornamented in any desired pato tern on its exterior surface. To achieve this result, I take a plain tube A, of any desired 5o that of the tube. Being slightly resilient, the
ribbon is formed to a spiral, which is loose on the mandrel. This spiral is then removed from the mandrel and slipped on the tube, one end of the ribbon is secured at or near an end of the tube, and the ribbon adjusted on the tube, wound tightly, and secured at its other end. In practice I prefer to use a thin metal stripif of sheet-brass, say, .01 inch thick-and it is obvious that a more delicate pattern can be produced on strip metal of this gage by an inexpensive process, as by passing between rolls, than can be indented into a relatively heavy tubing.
In Fig. 1 of the drawings I have shown how a more complicated pattern may be produced by the use of aplurality of strips B B, wound upon a plain tube A, as before.
In Fig. 3 is shown a sectional View of an embossed strip B, applied to a plain tube A, one edge of the strip overlapping the other. In some cases, and especially where the tube used is polygonal in cross-section, as shown in Fig. 1, this overlapping strip .is preferable to one the edges of which abut, as shown in the former figures.
Besides the advantages above named, it will be seen that a relatively cheap or strong tube may be used with a more expensive or easilyornamented wrapping. Again, it is often advantageous that a portion of a tube should be ornamented while another portion is plain, as shown in Fig. 20f the drawings. This result is not easily obtainable in a solid tube.
Ihave indicated one convenient mode of applying the metal strip or ribbon; but it is not to be supposed that I am limited to any particular process. I have also spoken of the strip or ribbon as of sheet metal; butit is obvious that a cast-metal strip may be used, if preferred. It is also plain that the particu- 9o lar metal of which either the tube or coveringstrip is made is non-essential to my invention.
I am aware that tubing has heretofore been made by wrapping a metal strip spirally around a mandrel, securing the abutting or 5 overlapping edges of the strip to each other, and removing the mandrel; but I am not advised that a tube has before been made by wrapping an embossed or otherwise ornamented strip of metal around a tube'and semo curing the tube and strip together, as herein 2. In combination, a tube and a coveringdescribed. strip wound spirally thereon and secured 1o WhatI claim as my invention, and desire to thereto, the edges of said strip abutting secure by Letters Patent of the United States, against each other, substantially asdescribed.
5 is as follows: CHAS. MASOHMEYER.
