SPECIFIGATION forming-part of Letters Patent `o. 746,521, dated December 8, 1903. Application filed February 28, 1903. Serial No. 145,469. (No model.)
To all` whom, it may concern:
Be it known that I, WILLIAM AUGUST KA` GELMACHER, Jr., residing at Johnstown, in the county of Cambria and State of Pennsylvania, have-invented certain new and useful Im provementsin Drilling-Machines, of which the following is a specification.
This invention relates to drilling-machines l and it consists of a peculiar machine of that character involving novel and improved de-` tails of construction for drilling holes in shaft-` ing-rods and other places without removingI the work from its fixed position.- More definitely stated, the invention involves peculiar and novel means for securing the machine and drilling holes regardless ot' the angle or posiy tion thereof;
The invention comprehends improved means for` supporting any common drill adapted to the purpose; but it is speciallyintended for supporting' portable pneumaticdrilling-tools that are well known and now used. Y Y
In order to enable others to make and use lny invention, I will now proceed to describe it in detail with reference to the accompanying drawings, forming a part of this specitication.
In the drawings, Figure 1 is a view show, ing my invention in side elevation and part broken away. Fig.` 2 is a detail top plan view ofthe drill-tool-supporting beam. Fig. 3 is a view looking down on the angular base mem-` bers and with the vertical post providing support for the drill-tool-supporting beam in section, taken on line 0cm of Fig. 1. Fig. 4 is a detail end view of the base members 'and sliding block and also showing part of the vertical post. Fig. 5 is a detail end View of the base members arranged upon a circularl tube shaft or bolt. The view also'illustrates one of my peculiar clamps for holding the work while being drilled. Fig.'6 is a trans- Verse sectional view through the drill-toolsupporting beam, taken on liney y of Fig. 1. Fig. 7 is a detail vertical sectional view through the drill-tool thrust-block and connected parts, and Fig. Sis a bottom plan View of the drill`lool thrust-block. y
In carrying out my invention I employ angular elongated base members A A', having on their inner sides undercut guideways B B',
cured thereto (see Fig. 1) by a bolt E4.
adapted to receive the T-shaped cross-head C on the under side of a suitable block D. The base members A A are respectively constructed with outwardly and downwardly inclined sides A2 A3, extending from the guideways B B'.- y (See Figs. 4 and 5.)
Referring to Fig. 1 of the drawings, E indicates a suitable standard or post having an angular foot E', `through which latter passes a suitable securing-bolt E2. The head E3 of this `bolt isfmade large enough to span the space A4 between theA base members A A', substantially as indicated by the dotted circle. (See Fig. 3.) The standard E is, in fact, an extension of the sliding block D; but asillustrating one construction I show it se- For xedly securingl the sliding block D and the standard E to an adjustmentalong the base Amembers A A', I provide the latter with a series of transverse holes E5, adapted to receive a bolt E6, passing through the base l members and the cross-head C of the sliding block D. (See dotted lines in Fig. 4.) The bolt E2 is intended for two purposes-iirst, to provide bracing-suppo-rt for the standard E, and, second, should it become necessary in using my invention to adjust the sliding block'D to position on the base members A A', where the bolt-holes E5 do not register with the similar hole through the crosshead C, the nut E'7 on -its upper end may be screweddown on the foot E' suciently tight to hold the standard against sliding i movement. In connection with the base members I employ end clamps F, (see Figs. 1V and 5,) that are substantially U-shaped. These clamps have upper tightening-screws F', that work against suitable blocks F2, resting on the base members (see Fig. 5) and a lower chain device F2. One end of this chain is iixed to the end of one leg of the clamp, and its other end is adapted for engagement with a suitable hook F5- at the lower end of the opposite leg of the clamp. (See Fig. 5.) In this view of the drawing G indicates a tube shaft or bolt arranged in the V-shaped recess formed bythe inclined inner sides A2 A3 of the base members A A. The work G, as above den'oted, is held in position by the chains F3, adapted to be drilled. In .other words, the base members of the machine are IOO secured to the work by the end clamp and chains, as will be described further on.
In further carrying ont my invention Iemploy apeculiar beam H, adj ustably supported on the standard E. While my invention com prehends any suitable means adapted for suitably supporting the beam H, in Figs. 1 and 2 I show one way of carrying out the idea. the inner end of the beam H is provided with a vertical perforation I, adapted to receive the standard E. The beam H is secured against horizontal or vertical movement on the standard E by a collar J, having a binding-screw J', the collar being vlocated below the beam, as shown in Figs. l and 2, and a horizontally-disposed set-screw J2 in the end of the beam having its end adapted for locking engagement with the standard E, and thereby hold the beam to any desired horizontal adjustment. In Fig. l I show a shoe .I3 between the standard E and the binding end of the set-screw J2. The object of the shoe .I8 is simply to afford increased binding effect of the set-screw on the standard.
It will be noticed that in the under side of the beam H (see Figs. l and 6) I provide an elongated recess K and support therein a feed-screw L, upon which is arranged an adjustable block M, conforming to the shape of the recess K. The inner end of the feedscrew L may be stepped into a socket L', (see Fig.l,) adapted to receive lubrication through a suitable passage L2. By reference to Fig. 2 it will be noticed that the outer end of the feed-screw L passes through a reduced opening L2 in the beam, and beyond which opening a socket or recess L4 is provided adapted to receive a collar L5, fixed on the feed-screw. The collar L5 is held in the recess L4 by adetachable end plate L6. At the extreme outer end of the feed-screw L, I provide a handwheel L7. It is understood that the outer end of the feed-screw projects-througha suitable opening in the end plate L6.
'Ihe sliding block M, hereinbefore referred to, is best shown in Figs. 6 and 7. In its preferred form it has side projections M', projecting under the beam H, which serve to prevent lateral movement of the block on the feed-screw. The side projections may be inclined downwardly to a reduced portion M2 and the, latter end with a lower enlarged and circular head M3. On the under side of the head M2,I arrange a rotatable thrust-blockN, having in its bottom a series of depressions N2. The thrust-block N is held in place by straps N3,f1Xed to the head Mand formed with angular lower ends N4, adapted to enter a groove N5,extending around the thrust-block, as indicated by the dotted lines in Fig. 7. The upper side of the thrust-block has a circular rack N6, with which a suitably-supported bevel-pinion N7is adapted to engage. This pinion is fixed on a stem N2, having an outer crank or hand-wheel N9. The object of the depressions N2 will appear farther on.
In' these View it will be noticed that.
On the upper side of the beam H, I arrange two U-shaped clamps O, adapted to vbe secured by opposite set-screws O'. These clamps have side extensions O2, with perforations adapted to receive and support elongated rods O2. (See Figs. 2 and 6.) On each rod O2,I arrange two rings O4, from which latter depend short lengths of chain O5, the use of which will appear further on.
P denotes any type of pneumatic or other drill employinga feed-screw P',having an upper conical end P2,adapted to enter one or the other of the depressions N2 in the thrust-block N. In my drawings I have shown the upper end of the feed-screw of the drill-tool in the central depression of the thrust-block N. According to my invention the drill P is supported with its upper end against the thrustblock N by a Vpeculiar sling arrangement, which Iwill describe as follows: Q Q' denote two tension devices located, respectively, on opposite sides of the drill device or tool. (See Fig. l.) Each tension device is formed with upper and lower spaced bars Q2, between which compression-springs Q3 are arranged. Up through the bars Q2, near each end thereof, I pass a rod Q4, having a lower head and an upper hook Q6, as shown in Figs. l and 6. The hooks afford detachable engagement with the chains O5. In further describing my invention reference is had to rods Q7, extending down through the bars Q2, at the end thereof. It will be noticed that these rods are similar to the rods Q4, but reversely arrangedthat is, their heads Q8 are above the upper bar Q2 and their hooked ends Q9 below the lowermost of the two bars Q2. The latter-stated rods Q4 pass through the com pression-springs QS between the upper and lower stated bars Q2, as shown in Fig. 6.
In connection with the tension device above described I employ two side chains R R', whose links are adapted for engagement with the lower hooks Q9, and thereby form two parallel swings which are connected by two spaced transverse chains S. It will be noticed that the parallel chains R R' and the transverse connecting-chains S are arranged under the drill-tool, and when they are properly adj usted the upper end of the feed-screw P' of the drill-tool is held yieldingly against the thrust-block N.
In Fig. l of my drawings I show thel beam H and the standard E marked with degrees, the use of which will be understood.
The chief advantage with my invent-ion over all machines known to me resides in its adaptability for drilling holes in shafting, tiebolts, and in all similar articles or devices without removing them from their fixed position. Its conformation is such that all the parts can be constructed at minimum expense adapted to the work to be done.
In use the base members are arranged on the tube bolt or rod in which a hole is to be drilled, as shown in Fig. 5, and secured thereon, according to the position of the hole to be IOO IlO
ldrilled, by the end clamps F and-their chains l inclined sides,
F3. It is apparent that'the base members Amay `be securely aftixed to the work by means of the tightening-screws F'. The drill-tool being in place and supported by the sling devices, with the upper end of its'feed-screw P in the concentric `depression N2 of thethrustblock N, obviously it is in position to drill a vertical hole or opening into the work to which the base members A A' are secured; In Fig. 1 the beam H and drill-tool are shown elevated; but it is understood that by loosening the screws J .I2 the beam may be lowered on the standard E to proper height gaged by the degrees marked thereon, adapting the drill-tool to the work that is to be drilled. In other words, the drill-tool is adjusted to position, with its point directly over or in the space between the two base members in position, where by simple manipulation of the feed-screw, with the drill-tool in operation, a hole can be drilled in the work to which the machine is secured. When it is desired to drill a hole other than vertically, the upper end of the feed-screw P' is placed in one'of the outer depressions N2 in the thrust-block N. After drilling one angular hole, as vjust described, the thrust-block N may be rotated by the hand-wheel N9 and rack and pinion N6 N7, thereby canting the drill-tool adapted for drilling another hole at an opposite or changed inclination. It is further apparent that my drill-tool can be adjusted along on the beam H by working the hand-wheel L7. In making this adjustment the rings O4, connecting the sling device, as above described, will slide along on the side bars O3. The clamps 0, that support the side bars O3, may also be adjusted by loosening the screws O.
Those skilled in the art will understand that my invention is adapted for drilling holes in work other than the article or thing to which the base members are secured. The beam H may be turned upside down and the drill-tool be supported uppermost, adapted for working overhead. It can be swung sidewise on the standard E and secured or locked to the adjusted position `by the end screw J2.
With my invention a series of spaced holes may be drilled without the necessity of measurement. constructed as hereinbefore described, provides adjustability of parts, whereby large or small drill-tools may be employed. The tension-springs securely hold the upper end of the drill-tool against its thrust-block and at the same time allow the drill to be fed down by its feed-screw P. The tension-springs also act upon turning the feed-screw of the drill-toolbackward to withdraw its bit out of the drilled hole.
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is
