nathird of parts are of well known and usual construction.
The nie fwltiiivdoff the heed-,piece consists in enlgig its bore adjaoent to the rjoint. This enlargement begins at the point e. proximately half w'jf'betvf'ee'the mo''tii- Yhole in the embouchure Aig,z1 l t ;1 13 a "oint por tion of the hesldiece und 'gra u'ily' ihcreases to theghi est point, remains constantfo'r c 'short' istance an'd nien decreases slightly for a shortdistanee until it r'ehes the -jointwhere it drops to the constant dimension ofthe iointund thefbod `fporton y 'edraw'ings igure 3, the is -,shown in sectional view andthe rgemen't is exaggerated in order better t0 .show thsfeature. For the purpose of illustration, I haveshownin Figure j'viirious lines Axliunubeifed to. 59. inclusive, di'reted t -vans parts of vi'hihis shown to pbinfiz-thef-ipsideniamer of e joint i s 4 37 thousendths, the same as the inside diameter- V f the l bore .of the body-portion.

The niethodof shaping the metal tubing to frx'n the heud-piece is as follows. I Iii-st takeya. `piece of suitable metal tubing 54 of great'erlength than thehead-piece Vsind place in it a's'teel arbor of the form shown in Fie.
4. The arbor has a'main portion 56 whic i is in outside form and dimensions identical with the -form and inside dimensionsvdesited in theJheud-piece and reduced end portions 58 and 60. 4In Fig. 4: I have marked the parts of the arbor corresponding to vthe points. 10 to 52 inclusive in Fig7 3. Near point 52 the arbor is provided with an anmiler ove V62 into which the metal tub' 5 1; fis rst spun in order to .prevent its displael'nent on the arbor lduring the processA of forming vthe tube around the arbor.
After the tubing has been arranged on the arbor as shown o n Figure 5, the arbor and tubing are pushed end 60 foremost through cakes of lend of substantially the form of the die shown Vin Figures T and 8, having a Central bor'e slightly srxiallerthan the tubin This operation reduces the size of Vthe tihg "slightly and by using successive the heed-piece,
For. @profi-f lend 58 of the erboiiot having been reduced ing at the groove After thetub' hais' n removed from the :irbo'i` theportioniof -the 't bin" pleines fregna Ji is neit :ie t e joint y, ai'4 t aten' il if. metal die 64 hpa'viriga ntrnLbOrbggthebore being bevelledalt 68 to reeive of the tube` This operation formed in any suitablemanner, Vsu't;li,"f o1 iiis'tunce, us placing'the diein a, lathe and then, forcing the tubethrough the -die into the position shown in Figure 9. .This reduces that end of the tubing to the dimeterde sired for the joint.
In order to drive the tubing out .of the die I Varovide a, suitable plug huvin.g -e hoad 70 anc a1 `central extending portionf'qaidmrtf ed to be inserted within thetubing t e die as shown in Figure 9. T edie, tubing and 'plug are 4chen mounted in un ordinal@ lathe with the tailpiece 711 of the. lathe in iaith@ engagement with 'the head of the .plug 70 and the heudfpiece 76 of the lathe in engagement with the die. A spindle in 'the lathe is then turned to cause the tailpiece to approach the head-piece, thereby forcin thedieto the end of the ,tubing from W ich it maj* be easily removed.
By the foregoing methodit is possible o secure a gr'e'nt variety of differentc shiuped bores in nie'tiil 4tubing find Where niety and exact accuracf is desired, such for instance, as in musica instruments, the results attained are of great importance.
What IE claim is:
1. A method of shaping metal tubing, consisting in forming a piece of tubing around an arbor of the shape desired for the finished work by forcing the tubin and arbor throu h one or more cakes ofg soft metal and t en removing the arbor fromV said tubingafter it has been formed.
2. A method of shaping metal tubing, consisting in providing an arbor of theexact shape and dimension desired for Vthe inside bore of the tubin mounting said tubing on said arbor an then forcing the arbor and tubing through leaden cakes to reduce the tubing to .fit said arbor. 3. A. method of shapin vmetal tubing, consistin in taking an ar or of the exact shape an dimension desired for the inside bore of the tubing, mounting the tubing on said arbor and securing said tubing thereon by spinning a portion of the tubinlr into a roove; then forcin the arbor an tubing irough a leaden ca e to reduce the tubing to fit said arbor and then removing the arbor therefrom by forcing it out of one end of said tubing.
4. A method of shaping metal tubing consisting in providing an arbor having aportion of the exact form and dimension of the bore desired in said tubing and being pro-4 vided with an annular groove lacing a. piece of `tubing ofV the required iength on said arbor and spinning it into seid groove on said arbor to hold the tubing thereon; then forcing the arbor and tubin through a pluralityA of leaden cakes, eac of said Vcakes being provided with a smaller bore than the previous one in order toreduce the tubin to t the arbor.
5. i method of shaping metal tubing, consisting in providing an arbor having a portion of the exact form and dimension desiledlfor the bore of said tubing, mounting the said tubing upon said arbor and securin it thereto by spinning or otherwise, an then forcing the arbor and tubin through u. eluralty of leaden cakes, eac of said ca. s being provided with e smaller bore than the previous onein order to reduce the tubin to t the arbor and finally cutting the tliing at the desired point and driving the arbor out of one end of said tubing.
6. A method of` shaping metal tubing, consisting in forming a piece of tubing around an arbor of the shape desired for the `nished work by forcing the tubing and arbor through a cake of Soft metal, havin u. bore suiiciently small to reduce said tubing to fit said arbor.
In witness whereof I hereunto set my hand this twenty-third day of April, 1921.
