WALTER 'rnnononn KnAUscmoF LA GRANGE, masseus F. WEBER, 0F oHIcAqo, ILLINOIS. j j v 'RAiL-DBILLING can.

To all whom it may concern:

' Be it known that we, WALTER T. KRAUsoH States, and residents-of La Grrange, in the county of Cook and State of Illinois,and of Chicago, in the county of Cook and Stateof Illinois, respectively, have invented certain new I and useful Improvements inv Rail- Drilling Cars, of which the following is a description, reference being had :-1-.o the accompanying drawings which form apart of our specification. j I

Our invention relates to a power-operated rail drilling car adapted to' drill the rails after the same have beenlaid or put .into place and on which the car is propelled; the device being especially intended for drilling holes in the web of the rail for the purpose of fastening rail-anchors, making joints; etc.

With our improved car, the drilling operations can be performed in materially less time than can be done with the manually operated drills at present employed; the device being capable of performing a greater amount-of work than is possible'to be accomplished by several rail-drilling gangs.- The invention permits adjustment of the drill carrying frame or portion to various sized rails or to positions for drilling indifferent horizontal planes, and also permits the work to be accomplished with great uniformity and accuracy.

The invention contemplates a self-propelling car adapted to move along the rails on which it is to operate;-the motive' power whereby the car is' propelled being also adapted to actuate the drilling mechanism.

The member 29 is provided with"a'screwb'ol't3'0 which is intended to engage with the head of the rail, as shown in Fig. 2; the adjusted position ofthe bolt being maintained by a set 'nu't 31.

I The frame 25 is also provided with the depending hanger-portions or sleeves 32 and 33, adapted to support the drill mecha nism which consists ofa rack-bar 34, bored to receive a drill-spindle 35 and permit the latter to rotate therein; one end of the spindle being "provideclw-ith a head or-"drill chuck po'rti'on- 35 in which the drill 36 is "remov'ablysecured;S'wl1ile at an intermediate anti-friction tearing intermediate of the bushing at the end of the rack-bar 34 and the 'd-rl-ll-chucl'rrpo'rtion 35 -M'ove1nent of the rack-bar' 34, lengthwise of the drill--spin-. dle,'is prevented by the nuts 38* which screw onto the threaded portion of the drill-spindle against the bushin g '37, thus holding the rack-bar intermediate of nuts 38" and the chuck -portion 35 of the spindle 35. 'The drill-spindle '35, at a point adjacent the nuts I 38, is provided with a sprocket 39, feath- "ered on thespi-ndle 35, as shown in Fig. 3,

- so as to cause the spindle 'to rotate therewith and at the same time permit'thespindleto travel in a lengthwisedirection; the

*spindle being provided with a "suitable key or slot wayextending lengthwise thereof for a proper distance.

The hanger-portion 32 'of'the frame 25 is prov'i'dedwi'th a suitable bushing 40 which has the cupped flange portion at 7 its" outer end, as shown in Fi 6 3, to .receive the flanged end 41 of the extended hub 420i the I sprocket ":39;

The flanged portion of the bushing 40 is adapted to have thea-nnu lar member or ring 43 secured thereto bym'eans of suitable screws or bolts 44; the ring 43 being adaptedto engage with the flange -41 and thus prevent movement of the sprocket 39 lengthwise offthe' spindle 3-5.

: Thesprocket 39 is adapted to receive a secured one sleeve-47 mounted on s'haft26.

- 48 which receives chain 49 which also cured on a screw-shaft :51 rotatably mounted passes about a lar gesprocket wheel 50 se- 'in-suitablebearings provided in the upright portionsof the frame 25, at a. point above the. pivotal point of the frame, as clearly shown in Figs. 1 and 2.

' The sleeve 47' is preventedfr'om moving longitudinally of shaft 26 by the bearingb'ljock or hanger 28 'aswellas-the frame 25. The sleeve 47 extends beyond the frame 25, namely to the left in Fig. 2, and is vjide'ol with a sprocket or pulley 52, which ljeceives a chain or belt 53 which latter takes about a suitable pulley on the power or driving shaft-54 of, the engine or motor. The sprocket wheels 46 and 48 are keyed to the sleeve 47 so as to rotate therewith, while the sprocket wheel 52 is loosely mounted thereon' and has its hub provided with; clutch engaging surfaces, see Fig. 2.

Feathered on theouter end of the sleeve 47 is a clutch-member 55 adapted to be operated by the lever 56 and thereby brought into. engagement with the clutch surfaces on the hub 'of the sprocket 52. With the clutch 5 5 thrown into engagement with sprocket 52 power will'be tran'smittedto the-sleeve 47 and, in turn, to the sprockets '46 and 48.

Lever '56 is fulcrumed at 57 on asuitable standard or bracket 58. p I H U Pivotally secured to. the cross-bar 25 of the frame 25, by means of a link 59, isa

lever "60;, the lower end whereof is madein the formof a sector "61 and. provided with teeth which rnesh with the rack-bar 34.

The leverifiO, adjacent the upper end, is

preferably bifurcated at the point,62 so as to straddle the screw-rod,51 and atthe same time permit the lever to be oscillated or swung through the are of'acircle and thereby cause the rack-bar 34-, and with it drills'pindle 35, to move in a horizontal direction.

pro-

In order that the lever 60 maybe automaticallyimoved through onestroke of its roscillation'and at a consistent and even degree, we ,provide a gripper member 63, which is adapted to take about the screw-rod 51, as shown in Fig. 2; the gripperbeing shown in detail in Fig. 4. The member 63 preferably consists ofthe two members 63 and 63 pivoted together at-64; with an intermediate portion of each member 63 and 631socketed and threaded at the point 63? adapted to mesh With the threads of the 'screw rod 51.

As i s apparent from the construction, the gripper member 63 willhave operative reportions 63? andfi63 are forced or drawn together and held in that position, thereby lation with the-screw-rod 51 as soon as the fcausing the gripper member 63 to travel along the screw-rod 51 in the direction 'or :lead of the threads thereof; it being under- Mounted on the same sleeve 47 is. a sprocket :lation between the gripper member 63 and .the screw-rod 51 will be affected or discontinued as soon as separation of members 63 and 63 is permitted. In gripping member 63, so as to cause the intimate relation bespindle, of course,

'at a andmaintained by the gage "tion to the perpendicular sprockets tween its threaded socket and the screw-rod 51, the member 63 will be made to travel lengthwise of screw-rod 51, and at the same time cause lever 60 to swing or oscillate through the arc of a circle, toward the left in Fig. 2. Such movement of lever 60 will force rack-bar 34 in a horizontal direction and bring the drill 36. into drilling relation with the rail 27 The link 59 provides a fulcrum for lever 60 and causes the latter to be firmly forced down into intimate relation with the rack-bar 34 as the link 60 swings from right to left in Fig. 2, and thus not only induces positive longitudinal movement of the rack-bar, and also of the drill-spindle 35 (by reason of the rack-bar engaging with the drill-chuck portion 35 of the drillspindle through the medium of the antifriction thrust-bearing 38) but maintains the drill in, drilling relation with the rail.

In operation,the car is run along the rails to the point where the rails are to be drilled for the purpose of fastening rail anchors or making joints, etc., when the frame 25 is swung downwardly so as to bring the drill carried thereby into the proper horizontal plane beneath the top of the rail; the horizontal plane of the drill being determined mechanism, comprising the gage arm 29'and set-screw or bolt 30; thus causing the holes tobe drilled at the desired height or point in the web of the rail.- It is apparent that by screwing-bolt 3O downwardly, the frame 25 will be forced" into a position at an inclina- (the frame being free to swing on the shaft 26), thus causing the drill 36 to strike the rail at a higher point on the web than would be the case where the bolt 30 is screwed upwardly so as to permit gage arm 29 to come into more intimate relation with the top of the rail. The frame25 having been thus adjusted, clutch 55, feathered on sleeve 47, is then operated by lever 56 (which straddles or is otherwise freely connected with the clutch) so as to form operative relation between sprocket 52 and sleeve 47 through the me- (11711111 of clutch 55. This will cause sleeve 4 to 47 and 48 to also rotate therewith; sprocket 46, through the medium of chain 45, causing the drill-spindle 35 with the drill 36 to revolve; while sprocket 48,

through the medium of chain 49, causes screw-rod 51 to be revolved; it being understood, of course, that the speed of rotation I of the drill-spindle, as well as of the screwrod, being determined by the relative sizes of the sprocket-wheels on the sleeve 47, drill-spindle 35 and screw-rod 51; the drillbeing intended to rotate greater speed than screw rod 51. Screw-rod 51 is, therefore, provided with the large sprocket-wheel 50 so that the speed be rotated, which, in turn, causes hole in the rail has been completed. The

gripping of member 63 will force lever'60 toward the left in Fig. 2 and cause the drillspindle 35, through the medium of the rackbar 34, to move longitudinally toward the rail. As soon as the drilling operation has been completed, the operator releases gripping member 63 from the screw-rod 51 and swings lever 60 toward the rightin Fig. 2, which causes the drill-spindle, through'the medium of the rack-bar, to be withdrawn from operative relation with the rail. The drill-spindle will be forced to the leftin Fig. 2, because of the intimate relation existing between the left hand end of rack-bar 34 and the nuts 38 which are screwed. on

the threaded portion of the drill-spindle 35,

sired to provide drill holes at different points or in different horizontal planes in the web of the rail, the lock-nut 31 on the gage-bolt 30 is unscrewed or released, so that bolt 30 may be turned in the proper direction and cause the frame 25 to be given the inclination necessary to bring the drill spindle in the desired horizontal plane.

It. is apparent from the construction shown and described that the operation of drilling the rails can be very quickly accomplished and the car moved to various points along the rail where the drilling is to be done; the clutch 55 being thrown out of clutching engagement with sprocket 52 after the drilling operations have been completed, and while the car is moving along the rail; at which time, the pulley, provided with belt 13, is thrown into operative relation with the power or driven shaft of the engine so as to transmit power to the axle or journal on which the wheels 11 are secured.
