Claims. (Cl. 33--21) This invention relates to implement guiding apparatus, i. e., apparatus useful in guiding a scriber or a torch in inscribing outlines for holes or in cutting holes into the sides of pipes or into plates as .may be' required for connection of meet- .ing ,pipes at various angles, or for passagev of pipes, rods and the like through them, and for other purposes.
The chief aim of my invention is to enable 'such-operations to be carried out expeditiously and at a minimum cost for labor, through provision of a simple and relatively inexpensive portable apparatus which is easily `applied to the work; which is readily adaptable to pipes of different diameters; which is capable of marking -out gures or cutting holes of different shapes .and sizes, as well as circles or circular holes of different diameters; and which can be used with equal facility `for operation on either horizontally positioned or upright positioned pipes and plates.
Other objects and attendant advantages will appear from the following detailed description of the attached drawings, wherein Fig. 1 is a view in side elevation of my improved implement guiding. apparatus. l
Fig. 2 shows the apparatus in top plan.
Fig. 3 is a horizontal section taken as indicated by the angled arrows III-III in 1.
, .Fig 4 is an end viewlooking as indicated by the angled arrows IV-IV in Fig. 1, showing a certain stage in the operation of the apparatus.
Figs. 5, 6 and 7 are cross sectional views taken 'as indicated by the angled arrows V-V, VI-VI and VII-VII in Figs.. 1 and 3.v l
Fig. 8 is a fragmentary detail cross sectional view taken as indicated by the angled arrows VIII-VIII in Fig. 3.,
Fig. 9 is a perspective view of one of the elements of the apparatus which will be more particularly referred to hereinafter; and t f t Figs. and 11 are views showing other condi# tions of use of the apparatus.
As herein illustrated, the apparatus comprises a vertically adjustable` frame which is comprehensively designated NI5V`and which is composed of two sections I6 and I'I bot-h built up of structural metal parts permanently united by welding. The frame component I6 is designed to serve as a main or base support and has a tie` rod I8 connecting a pair of spaced angularly configured saddles I9 and 25J adapted to rest on or against the fpipe P which is to be operated upon, as shown 42 f A a leg 23, and at 24,' a parallel horizontal -tievbar 25 which connects said leg with a second leg 26. From Fig. 1 it willbevnoted that the legs 2-3 and 426 slidingly fit respectively into -sockets 2-'I and 28 centrally of the tops of the saddles I 9 and l2li of frame component, I6, the leg 423 being provided at intervals with holes 29 vfor rselective engagement by a retractible pin 30 passed through a transverse aperture 3| inthe socket 21. As shown the tie rods I8 and 25 are extended to -equal'distances beyond the saddle .20 and the` leg 26 respectively as at 32 and 33. y
To the outer end of the bar arm 2| of the frame component I1 is bolted a bearing 35 for a vertical shaft 36 with a flange collar'31 at its lower end whereto -is flxedly screwed a head 38. This .head 38 is constructed from stout sheet metal parts including an inverted U-shaped center ele1nent39 whereto is bolted at the top a plate 48, and at the bottom a plate 4I, said plates extending laterally beyond said element 39 in one direction. Rotary movement is imparted tothe head 38 .by .means of a handvcrank 42 at one endof a short trans,-v
. t Engaged in Yguides 63 at opposite sides offene member 39 of thehead 38 are horizontal slide' bars 85 whereof the outer ends are rigidly con- .nected by a cross bar 66 which is secured by bolts Hrelative movement between the slide bars 65 and the bottom plate 4| of the head 38. I have accordingly provided for this purpose clamp screws 88a which are threadedly engaged in the cross piece 66 and which clamp againstbthe top ofV plate 4|.
Extending transversely beneath the bottom plate 4I of the head 38 and non-rotatively supported in clamp blocks 69 pendent from said plate' is a shaft 18 whereon are fulcrumed a pair of angular arms 1|. At their outer ends these arms 1| 4provide parallel guide tracks 1|a for a slide carriage 12 which is xable in adjusted positions by clamp ,screws 12a. As shown the carriage 12 ail'ords a tubular holder 13 for an implement which is exemplified as a verticallv arranged torch 14 having a pendent nozzle 15. Gas is conducted to the torch 14 by flexible hosing 18 held in a clamp 11 which is fixed on a radius to the top lof the bevel gear wheel 52. Fixed in an angular bracket 18 on the carriage 12 are studs 18, 88 and 8| which in riding on the curved surface of the pipe P maintain the torch nozzle 15 always at a definite distance from the pipe surface during the operation of the apparatus. It is to be noted that, the studs 18-8I are adjustable to diiferent lengths so as to function properly onpipes of different diameters.` Clockwise movement of the arm 1| about the shaft 10 is resisted by a pair of helical tension springs 82. At one end each of these springs 82 is connected to an upstanding projection 83 on the cross member 88, and at the other end, through interposition of a coupling wire 84, with the torch holder 13. At certain times during the operation of the apparatus. the coupling wires 84 engage grooved rollers 8,5as`shown in Fig. 4, these rollers being free to revolve on a rod 86 extending crosswise between the sides of the member 38of head 38. The arms 1| are biased .toward .the pipe P as shown in Fig. 1 by leaf springs 81 anchored on blocks 88 bolt-secured to the slide bars B5. arm 88 aflixed to the non-rotating shaft 18 at the center has a follower roller 90 at its end which roller is held to the edge of the cam disk 58 through the influence, upon the slide bars 65 of a pair of helical springs 9| respectively in tension between the blocks 88 and a medially fulcrumed lever 82 with its center I83 at the outer end of the` bottom plate 4| of head 38. Weights 84 at the end of arms 85 extending laterally from the head 38 are relied upon to balance the weight of the parts supported by the extended portions of the top and bottom plates 48 and 4| of said head.
Operation Yrevolves the slide bars 85 on which the torch vcarrying arms 1| are fulcrumed are moved horizontally through coaction of the roller 90 with the cam disk 58 whereof the shaft 55 is concurrently rotated by rolling of the spur gear 56 around the stationary spur gear 51, said cam disk 4 thus-determining the shapeof the hole cut by the torch 15. During the cutting, the arms 1| will be depressed by the leaf springs 81 and one or another of the studs 18-8I contact with the pipe in a manner readily understood from Fig. 4 to maintain the torch nozzle 15 at the desired distance from the pipe surface throughout the operation, the helical springs 82 acting in the meanwhile to counterbalance the weight of the torch.
For cutting of circular holes, the profile disk may be dispensed with. In such cases, the clamp screws 86a are tightened to prevent movement of the slide bars relative to the bottom plate 4| ofthe head 38. The torch 14 is thus kept at a fixed distance from the axis of the head 38, this distance being determined by adjustment of the torch carriage 12 along the track extensions 1| a of the arms 1|.
In Fig. .l0 I have shown how the apparatus may be set up to operate upon a plate P' supported horizontally. Here, the saddles I9 and 28 are simply rested .on the sustaining surface S and the frame section Il adjusted relative to the section I6 as may be reouired to properly position the torch nozzle 15 with respect to the plate P.
In Fig. 11, the apparatus is arranged for operation unon a vertically disposed pipeP", with the rod 33 of its frame I5 engaged, with capacity for up and down adjustment, in a. socket post 86. and the saddles I8 and 28 resting against said pipe in the manner'as described above in connection with Fig. 1.
Obviously, by substituting a scriber in place of the torch 14, the apparatus can be utilized to inscribe markings of different configurations or sizes with equal facility on pipes or plates in either horizontal or vertical position. The apparatus may moreover be employed for welding purposes if desired in a manner deemed apparent from the foregoing disclosure without necessitating separate description.
Having thus described my invention, I claim:
1. In apparatus for guiding an implement or tool to mark or cut holes into a surface; a, support; a member rotatable on the support about an axis perpendicular to the surface to be marked or cut; a slide guided by the member for movement radially of said axis and carrying the implement or tool; means for moving the slide including a shaft with rotative bearing in the member in parallel relation to the axis of the latter, a rotary cam on the shaft. a projection on the slide engaging the cam, a gear wheel secured to the shaft and a mating gear wheel fixed on the support concentrically with the axis of said member.
