The same Iparts in each of thefgures. j j j j My "improvement is made on the invention patented by niethe eleventh of June, 1850, `Where I for the `rst time in the history of i tight packing aroundfthe axle. Many attempts a this had before been made; but in leak; or if 'al spring wasl introduced -to `prevent that result,theffriction was so much j increased as to producelexcessive wear`,vheat,

and deterioration, that prevented any4 `economy orvalue in the use; j I j j My improvement above alludedto has was by itsconstruction `so difficult of access i ,i which my present improvement is calculated `to overcome; it consistsyin placing the parts composing thepackingon the inside of the I"`box`,"and inso arranging and constructing l them,`as to be acted on" from the outside end, without removing any of the parts, or getting under the truck to adjust it; and further, by puttingall the" adjustments within the box, I precludethe necessity of makwing holes throughit," bywwhich leakage of oil will occur`.` j l The description "is asfollows; viz: A is the journal box; B, the journal; C, the bear- `ing (a, @,)j` are annularpackings of leather,

or other suitable material; two ofthe leather `rings are used on the inside of the box ;l they are slipped over 4the endof the axle, and lit ted up against the inside "permanent tightener D, Fig. 3, `is then slipped over the end c of the Yaxle,7 and brought up against theV` ener (72) as'seen Fig. 1; the adjustable tightpacking, the fiangehorshoulders@ of the* same, fitting closely aroundfthe lower edges of the annular packing. `The bottom part of the inside adjustable tightener is forked, the two legs of which, (d, d) are rounded at the ends, as seen in Fig. l; F, is the adjusting frame lying on the "inside bottom of the journal`box;the endsl (e, e,).arerounded, so as jto correspond with the forks of the ad justable tightener; F isy a wedge or wheel which when turned around,or driven forces the adjusting frameforward, consequently drives up the adjustable tightener, so as to tighten the packing around the axle; when ysufliciently tightened ;the bracesk G Gr are slipped in, andholdff the tightener firmly 0n the packing. j The outside packing is held and adjusted nal box is cast the permanent tightening flange or shoulder (f,) as'seen in Fig, 6; the adjustable outside tightener, H, Fig. 7, has a corresponding flange. `The outside leather packing rings, (g, g,) are slipped over the journal or axle, the packing is brought up to its proper position against the permanent tightener, the ladjustable tightener, which had been `previously over the axle, is `then fitted `on to it,\the `Iiange or shoulder (la) of the same, `bearing against the lower edge of the packing; the tightener is then secured in properposition by means of the screws (c, le) which pass through the slots (Z, Z,) in

thetightener, and screw into the journal by means of the set screw (Wa). The packj ing being adjusted, and the box supplied with oil, the lid J, is thenput on and secured by means of the screw (n) the joints of the lid are made oil tight by means of packing (o). l j

It will be obvious toany experienced Inachinist, that the tighteners can be adjusted and held in proper position, in various ways, and by different arrangements of lmeans for that purpose; one of these devices is shown in Fig. 9, in Which E is a lever, Whose ful crum is at (e) the inner end of the lever passes under the center of the adjustable tightener D, and holds it up by the bearing down of the opposite end by the eccentric on Wheel F; the form of this eccentric is more clearly shown at Fig. 10. The Wheel is serrated on its edge, and is held in place by the cover J but it is impossible, especially in journal boxes for rail road trucks, that no screwT holes be made through that part of the box containing the oil, as the screws from the tremors and shaking consequent upon the motion of the truck, renders them very liable to become loose and fall out, consequently losing the oil; the outside and inside packing can be used together, so
