To all whom it may concern:

Be it known that I, ALBER'1 BALL, a cititaken in connection withthe accompanying illustration of one specific embodiment thereof, while its scope will be more particularly pointed out inthe appended claims In the drawings,\Figure 1 is a side ele vation of a channeling machine standard,

together with the attached reciprocating engine and crosshead, and embodying one form of my 1nvent1on; Flgl 21s a front ele-' vation of the parts shown in Fig. 1; Fig. 3

is an enlarged detailof the mounting of the rocker reverse lever 5 Fig. 4 1s a section on the line .44 of Fig. 3, and Fig. 5 is a section on an enlarged scale taken through the auxiliary cylinder head on the irregular line 5-5, Fig. 2.

Referring to the drawings and to the einbodiment of my invention there illustrated,

I have shown the tool standard A having an arched head (rand provided with longitudinal flanged guides a, a.' The remain} ing parts of the channeling machine are not herein shown, their specific construction being immaterial for thepurposes of. the in: vention, but they maybe of any suitable construction and the machine'is here assumed to comprise an ordinary track chane. neler at the side of whichthe standard'A is supported inan upright, position {and in a fashion well-known in'the art so'thati the tool can cut the'usual channel groove at the side of the machine: as the latter" vanced along the track-way.

Slidably supported" upon the" guides a" of the standard are carried theengine cylinder B and the cross-head guide said cylinder and guide being bolted to a pair, offgibs a;

breakage which is frequent wheretharchf isseparately formedand then bolted to the and the guide for sliding adjustment, there-- on ,as: a single unit. The cylinder-guide structure is adjusted to and from the work EPatentedJan. 16,1912.

by an adjusting screw d which is journaled in the arched head a of'the frame and there held against longitudinal movement, and provided with any suitable means such the ratchet lever ol by which the screw v may be turned. This screw acts to move the cylinder and the attached guide in any suit able way, as through the medium of the fixed nut (not shown).

. In constructing the standard, which, it will be observed, has two uprightside members ,mergingfinto the arched head and in substantiallythe same plane with thejou 'r- Y I nal bearing, for the screw (that is to say the arched head is without substantial forward overhang), I preferably form the head ii1,

[tegrally with the body of the standard, as

by casting the same in a singlepiece. This 'I have; found in practice considerably strengthens the arched'head and avo'idsdthe main body portion of the standard, thiszhav -q ing been the construction usually adopted in that type of channel'er employing the nonoverhanging screw support.

Bythe side of the engine cylinder Bis an interior valve (not shown) to which is '85 located the valve cha'mber' E provided with imparted a reciprocatory movement through Z the valve, rod 6 actuated throughconnee,

tions to the cross-head F,.the latter being suitably mounted for sliding movement upon the sliding cross-head guide I The valve referred to acts tocontrol reversalof the 1nain valve of the engine although its particular purpose and construction are not in set forth. i j w I .1 r

Reciprocatory movement is imparted to the valve stem 6 through its jointed 'con-.

free end oflthe lever being ointed to a link 6 pivotajll-y connected tofthe cross-head at 6 supportxattached to the'lower part of the cylinder head, such support thereby con-;'

siderablykobstructing the space below the cylinder head "and,preventing easy access Q material to theobject of the invention here;

to the packing gland b. In the present construction I have materially simplified the mechanism by providing a boss or fulcrum support 6 at the side of the sliding cylinder-guide structure and herein, although not necessarily, at the side of the crosshead guide itself. This removes the usual obstruction, heretofore necessitated by the pivotal mounting of the rocker reverse lever, from the space beneath the cylinder head and about the stuffing box gland 7).

Referring more particularly to Figs. 1, 2 and 5, the piston at its upper end is provided with a tail-rod 9 (see Fig. which projects through the upper end of the cylinder and is slidably mounted in a sleeve or bushing 71, the latter having a tapered seat in the auxiliary cylinder head H. The bushing h is held to its seat, and the open end of the auxiliary head closed, by means of the plug it threaded into the top of the auxiliary head. In addition to the guidance which is afforded by the presence of the auxiliary head H serving to maintain the alinement of the piston and cross-head, the said auxiliary head also provides means for lubricating the tail-rod and thereby supplying lubricant to the engine cylinder. For this purpose there is formed in the auxiliary head a hollow chamber 7?, which, being separated from the tail-rod by the bushing it, forms an annular reservoir for the lubricant. This reservoir may be filled or replenished through the passage 7L3 arranged in an offset portion of the head and closed by the plug h Leading from the lower end of the reservoir is the lateral exit passage h (see Fig. 5') having connection through the valved passage h with an annular groove 72. located opposite a series of apertures in the bushing which serve to conduct the lubricant to the surface of the tail-rod. The passage 72, is normally closed by the ball valve it the latter, however, being raised by superior pressure from beneath to permit the oil to pass to the tail-rod. Pressure is admitted intermittently at each forward stroke of the piston from the head end of the cylinder to the pressure chamber its at the end of the tail-rod through a vertical passage (shown in dotted lines Figs. 1 and 5) formed in an offset portion 71- of the head and directly connecting the cylinder and the chamber it". When pressure is thus admitted it enters the groove 717 and lifts the ball valve it to the space allowed for ball movement by the adjusting screw It (Fig. 5). When the ball is lifted oil passes to and within the bushing 71- and by reciprocation of the tailrod is carried to the cylinder, oiling the parts gradually as required, By adjusting the screw h the lift of the ball and the feed of the oil may be regulated as desired.

While I have shown and described one form of my invention for the purpose of illustrating the parts thereof, it is to be understood that extensive departures may be made from the details of the described form without departing from the spirit thereof.
