6, Claims.

My invention relates to improvements in loom reeds and an improved method of and an apparatus for their manufacture.

This application is a divisional application of my application for patent on Loom reed and method and apparatus for its manufacture, Serial Number 699,207, filed November 22, 1933.

A loom reed is preferably made up of a plurality of parallel flat wires or dents held by bars at spaced distances from each other. The ends of the dents have hitherto been mounted in two entirely different types of bars. They have either been mounted in so-called pitch bars, such as are shown in Patent No. 623,196, issued to Byron Wood on April 18, 1899, which comprise substantially semi-cylindrical wooden bars laid on each side of the dent ends reinforcedinside by metal strips and having cord means wound around them in spiral,

formation iii-between each dent and with the wooden bars, metal strips if employed and cord means covered over with a pitch covering to flexibly join the ends of said dents together at spaced distances, or the ends of the dents have been rigidly secured together by metallic means such as is shown in Patent No. 1,662,591, issued March 13, 1928 to Harry Titmas. A difiiculty with the pitch bars alone has been that in due course of time the pitch and cord meansbecome worn and the pitch bars tend to break up, or not hold the dents the desired predetermined amounts apart. A disadvantage of the rigid metallic means rigidly securing said dents together has been that; said means does not permit of any flexibility of the dents. 'Employing my'invention, however, I am able'to combine the advantages and largely eliminate the disadvantages'of each of these former types. By providing a rigid fulcrum with my rigid attaching means inside of the usual pitch bar means I achieve a large degree of flexibility in the dents by permitting the dent ends to be mounted so that they may freely move laterally in the pitch bars and at the same time I strengthen the former types of pitch bar reeds by adding a rigid support inisde the pitch bars thereof and I am enabledthereby to provide a reed which will stand up much longer than any pitch bar reed hitherto produced and which will have the usual advantages of a pitch bar reed. In order to solder a spiral spring to a pitch bar reed immediately inside of the'pitch bars without melting the pitch bars, I have devised the novel method and apparatus shown and described herein for so doing. I have found in practice that this is an extremely difiicult thing to do, namely, to apply the solder evenly to eachside of the spring to rigidly secure it to the dents without causing the heat. of soldering to melt the pitch bars and I have accordingly devised an apparatus which when the reedis held in a vertical position will apply the solder to each side of the spring without causing any melting of the pitch bars.

Further features of my invention relate to the improved structural details of the improved apparatus I preferably employ for this purpose, which primarily adapted for applying solder to a reed bar may be employed if desired for applying solder along lines on both sides of other objects. These and such other objects of my invention as may hereinafter appear will be'best understood from a description of myimproved reed and improved'apparatus.

In the drawings, Fig. 1 is'a disassembled side elevation of a reed after the pitch bars have been attached but prior to the attaching of the usual end cap members, springs and reinforcing spring strips and the soldering of the springs to the dent ends and showing the lower spring in the relative position it assumes in the completed reed.

Fig. 2 is a side elevation of a reed constructed in accordance with my invention.

Fig. 3 is a vertical sectional View thereof taken along the line 3-3 of'Fig. 2.

Fig. 4 is an end view of the improved apparatus with my invention. As shown in Fig. 2, said reedlii has a plurality of spaced fiat wires or dents l5 vertically mounted in spaced side by side relationship. and longitudinal pitch bars 12 flexibly join ing opposite ends of said dents together preferably at points spaced from the ends M of said dents. While the pitch bars 12 may be constructed in any of the usual manners, such as shown in Patent No.623,l96 heretofore referred to, the pitch bars preferably include the preferably substantially hemi-cylindrical wooden strips l9 having the flat inner sides 18 adapted to abut the dentspreferabIy at points equi-distantly spaced from the ends thereof and arcuate outer sides 20. In my preferred embodiment, the outer sides of the wooden strips IE are preferably provided with the longitudinal grooves 22 therein adapted to re-- ceive the reinforcing metal. strips 24 which extend longitudinally of said grooves substantially to the ends of the Wooden strips. I then wind the cord means 28 spirally around said strips I6 and 24 with upper and lower winds 28 thereof extending between the respective dents at the upper and lower portions of the pitch bars and I cover the outer surfaces of said bars and cord means with a covering of pitch 30 which may extend upwards and around the upper ends I4 of the dents 15.

Then if desired a paper covering, 34 may be applied over said pitch bars I 21 and upper ends I4 of said dents l5. The end cap members or bars 36 are preferably provided for joining the ends of the pitch bars I2 together and these are provided with the preferably cylindrical caps 88 at each end thereof adapted to enclose the ends of the pitch bars, including said wooden stri'ps I8 and metal strips 24 and be secured thereto by any suitable means, such as the nails 48 shown. As stated hitherto, this is substantially the structure of the former type of pitch bar reeds.

The spiral spring 42 is then laid over the dents I5 immediately inside of said pitch bars I2 so as to have the winds 44 thereof interposed between adjacent dents I5. This may be done by fitting the winds of the spring laterally from one side between said dents and not by screwing it in. In order to reinforce the metallic rigid fulcrum members in my device, I preferably employ the metal strips 48 adapted to extend longitudinally within the outer segmental portions 48. of said spiral spring and over the end members 36. I then by means of the solder means 58 rigidly join the segmental strips 46 and spiral spring 42 to each other and to the dents I5 and end members 38 on each side of said dents and end members to form rigid fulcrums for said dent ends inside said flexible pitch bars I2. It is thus obvious that the pitch bars form means for flexibly joining the ends of said dents together and that the spring and solder, and reinforcing bars 48 where employed, form metal bars or means for rigidly securing said dents together at spaced distances inside of said flexible means.

Considerable difiiculty was emerienced in suitably soldering the outer surfaces of the metal springs 42 and metal strips 48 where employed to the dents I5 immediately inside of said pitch bars I2 without melting the pitch bars and in order to accomplish this I have provided the improved type of apparatus shown in Figs. 4 and 5 for this purpose. Said apparatus includes the frame 52 suitably mounted on a support 54, although it is obvious that if desired the legs 56 of said frame may be lengthened so that the frame 52 may be readily mounted on the floor. I provide suitable means to clamp said reed constructed as aforesaid to said frame 52 in a vertical position, in my preferred embodiment, said means includes the vertical forwardly extending arms 58 longitudinally adjustable in slots 68 in said frame and secured thereto by the bolt and nut means 62 in adjustable positions thereon. I provide the clamps 64 each having a vertical slot 88 on one end thereof to receive the upstanding end 88 of an arm 58 therein and be vertically adjustably secured thereto by means of the set screw 18. The front end of said clamp 64 is provided at its lower surface with the longitudinal slot I2 for receiving the dent end rib 39 of said pitch bar. A suitable vertically adjustable support I3 is provided preferably extending the length of the frame and having a longitudinal groove I4 therein for receiving the lower dent end portion 39. Said supporting means I3 is preferably provided with said spiral spring simultaneously.

the depending end legs I! having the vertical slots I8 therein so that it may be vertically adjustably secured to the frame ends by the locking bolts 88.

I provide the solder troughs 82 extending 1ongitudinally of said frame adapted to hold the solder 84 and I provide suitable means such as the gas burners 86 for heating said solder troughs, although it is obvious that any suitable type of heating means may be employed. I also provide cooper bars 88 extending longitudinally of said frame and suitable means to raise said cooper bars 88 from said solder troughs 82 to abut opposite side portions of said lower spiral spring 42 simultaneously with equal pressure to apply the solder retained in said cooper bars 88 with equal pressure to opposite sides of While any suitable means may be provided for this purpose, in my preferred embodiment, said means includes the shafts 90 extending through said frame, each having a gear 92 of equal size intermeshing with the respective opposite shaft gear 92 on eachend of each shaft exterior of the frame. The handle 94 is provided to oscillate one of said shafts '90 to cause an equal movement of each of said shafts 98 through the medium of the intermeshing gears 92. The supporting bars 96 are provided projecting radially upwardly from each end of each shaft 98 having the outer ends bent first laterally as at 98 and then upwardly as at I00 for mounting of the cooper bars 88 thereon. The spring abutting portions of the cooper bars may if desired, be provided with solder grooves I82 to receive the solder from the solder baths 84 and bring it upwards to be applied against the outer surfaces of the spiral spring 42. If desired, as shown, the cooper bars 88 in addition to being supplied with the arcuate solder grooves I02 may be provided with the solder catching steps I84.

It is thus obvious that the formed reed I8 may be clamped to the frame 52 by means of the clamping means 64 and support I3, with the handle 94 first rotated to a position to receive the cooper bars 88 within the solder tanks 82 and that on rotation thereof each cooper bar will be raised equal amounts with equal pressure to abut opposite sides of said spiral spring 42 to apply solder with equal pressure thereto at aligned points thereon. It is thus obvious that by employing this improved apparatus, I am enabled to apply even amounts of solder on each side of the longitudinally extending spiral spring to secure said spiral spring to said dents without melting the adjacent pitch bar, by applying the solder through the medium of the cooper bars along the spiral spring only.

It is thus apparent that I have provided novel type of apparatus capable of producing the novel type of reed having the advantages described above.

It is understood that my invention is not limited to the specific embodiments shown and methods described and that various deviations may be made therefrom without departing from the spirit and scope of the appended claims.
