CHARLES H. OSLUND, OF WORCESTER, MASSACHUSETTS, ASSICrNOR TO AMERICAN STEEL 8: WIRE COMPANY, OF WORCESTER, MASSACHU- SETTS, A CORPORATION OF NEW JERSEY.
MULTIPLE DRILL.
Patented Oct. 9, 1906.
Application filed February 1, 1906. Serial No. 298,895.
To all whom it may concern:
Be it known that LCHARLES H. OSLUND, of Worcester, in the county of Worcester and State of Massachusetts, have invented a new and useful Multiple Drill, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification,
in which -with the track-rail in section.
Figure 1 is a plan view, partly broken away, showing a drill-machine embodying my invention in use. Fig. 2 is a front elevation of the same. Fig. 3 is an end elevation Fig. 4 is an enlarged plan view, partly broken away, showing the drill-ratchets. Fig. 5 is a'section on the line V V of Fig. 4. Fig. 6 is a detail view showing the drill adjustment, and Fig. 7 is a detail view of a portion of one of the drill-spindles with its ratchet.
My-invention relates to multiple or gang drills, and while it is useful for a variety of purposes it has been more particularly designed for using in drilling rails for rail-bonds, the object being more particularly to provide a simple and efficient machine which may be readily applied to track-rails for the purpose of drilling therein simultaneously a plurality of adjacent holes and which is so constructed that trains may be allowed to pass over the rails being drilled without removing the machine.
Other objects and advantages of the invention will hereinafter appear.
With these objects in view the invention consists in the novel construction, arrangement, and combination of parts, all substantially as hereinafter described, and pointed out in the appended claims.
In the accompanying drawings, the numeral 3 designates a supporting plate or bar which is provided at its end portions with the dogs 4 and 5, by means of which it may be attached, as shown, to the fish-plate 2 of a rail-joint. The dog 4 has a sleeve portion 4, which is swiveled on the pro'ecting stud 3 of the support 3 and is forme with a jaw 4 which engages the ends of the fish-plate 2 in the manner shown in Fig. 1. has a threaded engagement with the end por tion of the support 3 for the purpose of providing an adjustment so that the drills may The dog 5' properly fit any curvature or unevenness in the rail, the adjustment being secured by means of the nuts 6.
5 designates the jaw portion of the dog 5, which engages the opposite end of the fishplate 2.
. 7 is the base portion of the drillfran1e, which is mounted upon the supporting-bar 3, being secured thereto by the clampingbolts 8, which pass through an elongated slot 9 in the said bar, whereby the frame, together with the drill carrying and operating devices hereinafter described, may be moved longitudinally on the supporting-bar and secured in the desired position.
'10 is the drill-carriage, which is mounted on the frame 7 between the guides 11, being movable on said guides toward and away from the rail to be drilled by means of the feed-screw 12, having a hand-wheel 13. The shaft of the feed-screw 12 has fixed thereto aratchet-wheel 14. Adjacent to this ratchetwheel is a cam-plate 15, rotatably mounted on said shaft and by means of which the number of teeth exposed to the action of a pawl 16, hereinafter more fully described, may be varied. This cam-plate 15 is secured in desired adjustment by means of a lockingtooth 17 The purpose of this plate is to hold the pawl out of engagement with the teeth of the ratchet-wheel 14 during a certain portion of its stroke, during which the pawl is held from dropping into engagement with the teeth by the fact that it is riding on the edge of the plate. By adjusting the position of the plate relatively to the stroke of the pawl the effective stroke of the latter is varied.
18 designates the drills, whose shanks are secured in the rotary holders 19, which are provided With bearings 20 on the drill-carriage 10. The outer 'end of each'holder carries a ratchet-wheel 21, and between these wheels and the outer bearings 20 each holder is provided with a set-collar 22,
23 is a drill-operating slide which is arranged to reciprocate transversely in guides 24 on a forward extension of the drill-carriage frame 10 and which carries two series of pawls 25 and 26, the pawls 25 being hinged or pivoted thereto above the ratchet-wheels 21 and the pawls 26 being arranged below such 3O formed with slots 19 through which are incauses the wheels, as clearly shown in Fig. 5. This slide is 0 erated by means of a lever 27, having a socl et for a removable handle-bar 28. This lever is connected to a projecting lug 30 on the carriage frame by a short link 31 and is pivoted at 29 to a projection on the slide. 32 is a stop-arm for the lever carrying a hinged stop 33.
34 represents thrust-screws which are seated in a thrust-plate 35 and bear at their inner ends against the outer faces of the ratchetwheels 21, the latter having concave central bearing-surfaces 21 for these screws.
a; 36 designates two slotted arms which are pivoted to the drill-carriage at 37, the pivots passing through the slots in said arms, as best shown in Fig. 3. Adjustably secured to each of the arms 36 by means of bolts 38, passing through the slots 39, is a dog 40, which engages over the head of the track-rail A and is held in engagement therewith by a set-screw 41. Pivoted to a lug 42 on each arm 36 is a lock or finger 43, having a tooth 44, which engages a notch or depression 45 in the dog 40.
46 designates a graduated scale on one of the guides 11, and 47 is an indicator on the drill-carriage 10, arranged to traverse the scale and indicate the depth of drill.
In order to secure an individual adjustment of each drill 18, the drill-holders 19 are serted keys 19, which bear against the inner end of the drill-shanks and also against the faces of knurled nuts or collars 47, which are threaded on the drill-holder, as shown in Fig. 6. By the adjustment of these collars the drills may be moved in the holders to give them proper adjustment.
The operation is as follows: The drill is applied to the rail-joint to be drilled in the manner shown in the drawings by engaging the dogs 4 and 5 with the ends of the fish-plate 2, and the dogs 40 are properly adjusted and are engaged with the head of the rail by means of the set-screws 41, being locked by means of the fingers 43. The drill-carriage is then properly adjusted, and the lever-handle 28 is oscillated in a plane parallel with the longitudinal plane of the rails. This causes a reciprocation of the drill-operating slide, the pawls 25 operating the ratchet-wheels 21 in one direction of movement of the slide, while the pawls 26 operate said wheels during the reverse movement. As the slide is reci rocated the pawl 16, which is carried by tl ie slide, engages the teeth of the ratchet 14 and roper feed motion of the drillcarriage. 11 case it is necessary to permit a train to pass this can be readily done by loosening the screws 41 and disengaging the dogs 40 and moving them back to clear the rail. This can be done without disengaging the dogs 4 and 5.
By the arrangement above shown and described it is possible to quickly and accurately drill the bond-holes in the rails without disturbing them and without interfering with the passage of trains.
The construction provides for the use of a number of drills whose centers are but a short distance apart, so that close drilling of a number of holes is possible.
In place of the dogs 40 it is obvious that any form of dog which can be engaged with the heads of the rails may be employed, also that various other changes may be made in the details of construction and arrangement Without departing from the invention, since What I claim is 1. A multiple drill for drilling railwaytrack rails adjacent to the joints thereof, said drill having a supporting-frame, a drill-carriage mounted thereon, a plurality of drills, means for actuating the drills, and dogs movably connected to the frame and arranged to engage the end portions of the joint-plates; substantially as described.
2. A multiple drill having arms pivoted thereto, dogs adjustably secured to said arms and arranged to engage over the head of the rail to be drilled, and other dogs connected to the drill-frame and arranged to engage the fish-plate of the rail-joint; substantially as described.
3. A multiple drill of the character described having" a multiple-drill carriage, a frame upon which said carriage is movably mounted, arms loosely connected to said carriage, and pivoted dogs carried by the said arms and arranged to engage the head of a track-rail to be drilled; substantially as described.
