To .all 'whom 'it muy concern.:

Be it. known that; l, Enwa'nn l). trnonn, a

eiti'lzcn of the United States, andresidcnt of New York7 borough of lvilanhattan. county and .State of 'New York, have made a new and useful invent-ion 1n l)ack1ng-'l`ools, of

'which' the following is a specification.

My invention is directed particularly to improvements in packing tools designed fon" use in connection with condensers 'in power plants, where the opposite ends of condenser tubes are .secured in tube sheets and stranded packing is forced into position in Igrooves inthe vtube sheets around the outer ends of such tubes, and it has for its object7 to provide a power actuated packing tool which quickly and etlectually produces the desired referring to the accompanyingidrawings, in y `tubes being illustrated and the packing' end of the barrel portion.

shown in position, the operating` trigger of thetool being shown in side elevational view. Fig. 2 is a. detail sectional view illustrating a. part olf a tube sheet and a tub,\ together with the packing secured in position between vthe two by a tubular set-nut in the usual way. .F l is an .end vie f as secu looking` at the barrel portion ol the tool shown in Fig'. l l'roin lett to right.. Fig. 4: is ade-tail side elevational view o'lt the outer sido elevational view of that part of the tool which supports the packing cord preparatory to drivint it into place and which also constitutes at its free end a guide or support. for properly locatingl the tool with reitudi'nal see-y Fig. 5 is a detail from left to right in the direct-ion of the' arrows. Fig". 7 is an end elevational view of Fig. 8 as seen lookingr thor-eat from-lett to right. Fig. 8 is a side elevational view ot' the automatic operative .power iinpelled portions of the tool, the same illustrating also in broken sectional View the manner ot' controlling the motive parts by a motive agent7 such as air or steamiv Fig. 9 is an end elevational view as secu lookiiml at Fig. B from right to let't in the direction ot' the arrows.`

Referring to Fig. 2, l represents one of a pair of tube sheets and 2 onev ond of av single tube, the opposite ends of which are secured to such tube sheets in the manner shown, there beingl provided, as is well known by those skilled 'infthc art` ot steam power plants, the usual enlarged screwthreaded hole adapted to receive, when the tube 2 is in the position shown, the' packing' cord This parkingv is ordinarily in the nature Ot' tarred vor other enter-prorated strands or rcords ot' brous material, such as cotton, and in rn'aclice the packing thereof is effected al'ter the tubes are secured, their opposite ends in the tubesheets lirmly packing it lwith a. manual packing' tool, after which cach tube is smrounded with a hollow1 screwtlireaded set-nut turned tirmlyy home througli the agency of a screw-driver. This prot-ess ol pat-.king` between the ends of the tubes and the tube sheets is necessarily very tedious vvnen mainially'elleoted, and as often there are hundreds of such packings to bo ettectcd much time is consumed. My invention. therefore. is designed to cflcet. this packing much more rapidly and cli'ectnally', and also to more lirmly amass the pac-.king` than hasI herelioi'tne been possible by the woll known hand process.

For a full and clear understalidillg of my invention, such as will enable others skilled in thel art. to construct and use the in detail, and particularly to Fig. l, in wlxich 5 represent-s the breech or body .part of the tool which is integral with the handle 6, 7 'being a barrel, having' vent holes o, o, o, and"8 a diminished end, such parts being secured together by screw-threads as shown,

appearance. 9 represents a tubular recipro= eating-plunger provided with a piston 10 which tits accurately Within the barrel '7. ll represents a guide-tube enlarged at its outer end so as to constitute a guidesway for the reciprocating' plunger 9, said guidetube beingl screw-threaded and secured in corresponding screw-threads in the breech 5, as shown. 12 represents a .rotary shaft which tits accurately Awithin the 'inner sursaine, reference is now had to the drawings the whole structure simulating a'pistol inV face of 'the guidetube 11 and is provided:

with an enlarged journal bearing at its outer end, said tube being further enlarged at lli so as to leave a sutiicient space between it-and the diminished end 8 ofthe barrel to constitute a guide-way for the plunger t). lhe end of this enlarged part lit is turned down into the t'orm of a frustiiin of a cone, as indicated at ll, and is provided with a shoulder 1S adapted to tit accurately against the end o'l' the tube around which the packing is to bey inserted. This enlarged part 1.3 also constitutes a barrel or c vlinder around which the packing cord 3 is wound before the tool is/put in use, and for the purpose of securing this cord there is provided a longitudinal groove in the body part i3 in which pivoted upon a pin lt a longitudinal linger 1.3 grooved at its outer end,'as shown in Figs. vided with a spiral springl tainserted in a boring inthe part llt. the arrangement being" such that normally this linger l5 is held at itsI outer end against the inner face of the diminished cnd h' of the barrel. 1f.) is a spiral spring the function of which is to return the reciprocating plunger to its norinal position after it luis been actuated by y the motive agent, 'as gas.. 20 is a longitudi# nal slot through the diminished end of the barrel. said slot constituting an opening for the insertion otthe cord I, which is to constitute the packing. 2l represents an open-v convey' the propelling source of energy, as

air. to the piston lt).- aiid the latter to a driving motoras will he described later on. is a valve held in seated position by a spiral spring 23, said valve and spring bcing secured in position by a screw 2+. :25 is a hollow' valve operating plunger normally held in its outward position with the valve seated against the l'ulcrnined portion of a trigger .tt, secured upon a pivot pin and provided with a shoulder which normally permits it. the trigger, to he held i'n the position shown in li`1ig. l. 2S is the,I operative part of u rotary motor "29 secu'red lto the rear end of the ln'cech and having its shaft It() connected directly tov the rotai/'tyf shaft l2, itl heilig a detachable cap secured to the case ol'i the motor and provided with the necessary journal hearing, as shown. 252 is :i` pinion carried by the slial'tl itt), and Ztl-t is :i gear-wheel meshing therewith and adapted to rotate upon a journal hearing t-l secured to thc breech 5, Zt heing another pinion carried h'v i sha l't integral with the gear-wheel Si?, and meshing with a sccond geur-wheel Itt secured to thc rotary sha l't l2. 'aiv is a valve seated. under pressure. of .spring 3H, iii the channel )l running to the rotary part 2h, of the motor 2th and il is a .i'talve operatedl lever operatively connected .'i and t'. and pro-.

with and adapted to lift `the valve 3T under thumb pressure. t0, 40 are air vents for liberating the air after ithas passed through or acted upon the rotary part '28 ofthe motor 2t).

The operation is :s folloWs-In order to secure the packing cord in the tool, one end thereof is inserted at the' outer end of the slotQO (see Fig. 4) so that it is forced into suliieient frictional relation between it and the inner surface of the diminished end S of the barrel to be carried with it on rotation of theshaft 12, thus Winding it lirmly around 13. A source of power, as steamer air under pressure-preferably the latter-f operatively connected with the opening 2l land the operator then with his thumb lpresses the valve lever 39, thus allcving the air to pass inward through the opening 2l, channel 211 to the rotary part 2S of the motor '29. rotating it and hence through the shafts 30 and 1'2 imparting rotation to the enlarged part 13 of said Shaft 12, thereby d 'awing the cord through the opening 20 and winding it around such enlarged part until the desired amount of cord, which is usually eut in proper lengths, has been completely drawn therearound and iS-in position to be operated upon by the reciproeating` plunger t). The operator then liberates the valvei-ST and allows it to be seated, after which lie inserts the coned end ll of the tool into the endl of the tube 2 in the manner shown in Fig. l and then operates the trigger 26 successively a number of times unt-il the cord has been driien firmly home, the number of blows given depending upon the density he desires to give to the packing, as will be r adily understood by those skilled in the art. The tool is then removed and the set-nut 4 secured in position in the usual manner. In this way the operator passes from tube to tube and very quickly effects such packing and by reason of the reciprocating or hammer-like action of the plunger 9 he is enabled to more cifectually pack the/I `t'ahrie and wind the same in positionCto/he driven hv the reciprocating plunger; or, I

may utilize tuliular sections' ofgfabric -or analogous tracking which may he slipped into position m the tool by forcing' the-same endwisc evier the packing siippoit,"as for' instance. tubular lamp wiclts ot proper dlameter cut into sections ol' the desired length.
