APPARATUS FOR MANUFACTURING LEASE-REEDS.

Application filed January 20, 1906.

To all whom it may concern:

Be it known that I, OHARLEsA. Green, a citizen of the United States, anda resident of Worcester, in the county of Worcester and Commonwealth of Massachusetts, have invented certain new and useful Improvements in Apparatus for Manufacturing Lease- Iteeds, of which the following is a full, clear, and exact description.

The object of this invention is the construction of apparatus for the expeditious, accurate and economical application of solder to certain parts of the spaces between the dents in lease reeds used in connection with looms.

Referring to the drawings forming part of this specification, Figure 1 is a perspective view of the apparatus embodying my invention. Fig. 2 1s a side sectional elevation of a terminal portion of the apparatus. Fig. 3 is a cross section illustrating one way in which the apparatus may be made. Fig. 4 is a perspective sectional view of the same. Fig. 5 is a plan view of a portion of a lease reed. Fig. 6 is a cross sectional view of the ap aratus partially complete showing my pre erred manner of making it. Fig. 7 is a cross-section of my preferred form of a paratus.

Referring to Fig. 5, it will e seen that a lease reed consists of a multiplicity of small wires or ribbons of metal, 1, usually termed dents, terminally held by rails or ribs 2; the distance between the dents de ending upon the character of the work for which the reed is designed, and each alternate space 4 between the dents being subdivided into five sections. The preferable means for blocking said spaces 4 into the five sections is found to be solder; but the ap lication of such solder I find to be a very di cult, and tedious task; one, moreover, practicallyimpossible of performing with accuracy, owin to the tendency on the part of the melted solder to flow for irregular distances along the spaces by capillary attraction The object of this invention is the construction of means for absolutely limiting such irregular flow of the solder, so that the latter can be applied to the plain reeds with a maximum of rapidity and the results be always of the desired accuracy.

My invention for this purpose consists of a paratus carrying appropriate dams capab e of preventing-the flow of solder wherever Specification of Letters Patent.

it is not to go, while still permitting it to be applied wherever desired. For such a dam it is of. course necessary to use a substance to which the solder will not adhere; and the material which I have discovered to be the best for this purpose is aluminum.

In forming the apparatus, I have devised two diflerent ways of making the ap aratus, but will describe my preferred form later.

I In the ways shown in Figs. 2, 3 and 4., two

lease reeds

10 and 11 are laid one upon the other at the bottom of a shallow box 12, and

strips

16, 15 and 17 of aluminum are inserted therein in the three rows shown in Fig. 3, in the spaces between the dents of said reeds. Then liquid plaster-of-paris 20, or other very fine and fluid cement, is poured into said-box t0 the depth represented after this has set and hardened, and said strips therefore firmly held thereby, the apparatus is ready to be used in the manner hereinafter set forth.

The way in which I prefer to make this apparatus, as shown in Figs. 6 and 7, is to take two

plain reeds

10 and 11, and lay the latter 11 on the bottom of said box 12, with four bars or strips 7 and 8 extending from end to end thereof. The

aluminum strips

15, 16 and 17 are then inserted between said bars in the spaces between the dents of said reed; and the reed 1.0 impaled upon said strips near the upper ends of the latter, and suitably supported as upon nails 19 driven into the inner faces of the box-sides; care being taken to have said strips enter the spaces in the reed 10 corresponding to those in the reed 11.

Bars

5 and 6 similar to those below (7 and 8), are next laid upon the reed 10, and positioned to accurately hold the

strips

15, 16 and 17 in the vertical position represented in Fig. 6. For the particular lease reed taken for illustration, the bars 5 and 7 and the strips 15 are half an inch in width,

but any other special type of lease reed would probably be of other dimensions, and said bars and strips would accordingly be of different widths from these. The

bars

6 and 8 can be of any suitable width, as can the

strips

16 and 17. Liquid plaster-of-paris is now poured into the box 12 to the level shown in Fig. 7; and after it has partially set, care is taken to see that the

strips

15, 16 and 17 are not displaced in any way. When fully set and hardened, the reed 10 and

bars

5 and 6 are removed; the

blocks

21, 22, and the guide rail 23 applied. The apparatus is now ready to be used, with the exception of a device for enabling the completed lease reed to v be removed from the aluminum strips. or

teeth

15, 16 17. This consists of

bars

30, 31 fitted to be applied between the rows of teeth 15 and- 16, and 15 and 17, as shown in Fig. 3, and to rest upon the composition surface 20. When thus supported, there should be slightly more distance between their upper faces and the extremities oi the

teeth

15, 16, 17 than will allow tor the dents 1 of a reed applied as shown in Fig. 3. Upon said bars and snugly filling such space between the latter and the under edges oi said dents, as the reed rests upon the

blocks

21, 22, are placed plates or ribbons 38, 39 oi aluminum. These bars are made vertically removable from between the three rows of teeth by means of the

handles

32, 34 pivoted at 33 and 35 respectively between the ends of said bars, as shown in Figs. 1 and 2. These handles rest normally in the notches 27 of the plates. 36, but, when their outer extremities are depressed, they act to raise said bars as desired. See Fig. 2. As these bars rise, they force the completed lease reeds vertically upward out of engagement with the strips or teeth 15, 1 6, 17. The

bars

30, 31 being inplace, and the aluminum plates or ribbons 38, 39 fully covering the same, a plain reed is placed upon the apparatus, with one rib 2 pressed back against the rail 23, and the said teeth penetrating the spaces and terminating close above the upper edges of the dents. The workman now runs the nose of his soldering iron along each space between the

teeth

15 and 16, and the

teeth

15 and 17, until the entire reed is completed the bar solder being held against the soldering iron and melted thereby, and so keep up the supply to the nose thereof, in the usual manner. The completed lease reedis then removed as described above, and another plain reed applied.

Inasmuch as the aluminum, by its lack oi' ailinity for solder, forms a dam to the spread of the latter beneath the dents as well as where the solder meets the teeth, the lease reeds will all be formed exactly alike, and each one with the terminations of the sol- 1{dered spaces accurately in line, as shown in Although the

teeth

15, 16, 17 could be formed by milling or planing them from av solid bar of aluminum, yet the same could not be used in practice for the reason that the ribs 2 ol the reeds are generally of wood, and the expansion of the aluminum would be so great as to bring the teeth. far out of true with respect to the spaces in the reeds. But by employing a composition for holding the aluminum teeth which is not affected by variationsin temperature, and mounting the esaess same in wooden box with its grain running longitudinally and hence also unallected, I

wholly avoid any such dilliculties otherwise insurmountable.

I also find it essential to use a wooden box for receiving the plaster-of-paris, rather than a metallic box, for the reason that the plaster has to be so extremely liquid in order to thoroughly penetrate every crevice between the teeth and dents ol' the reed 11, that, were such box ol a non-porous material like metal, there would be a great loss of time in awaiting the perfect solidifying oi' the fluid mass.

The method ofusing plain reeds i'or accurately locating the teeth is also very important, as it would otherwise be practically impossible to group them in perfect alinement with the spaces in the reeds to be soldered.
