The above features, and others contributing to the e?iciency of the machine, will be apparent from the following detailed description of a preferred embodiment, as shown in the drawings. In the drawings, Fig. 1 is a side elevation of my pipe Working machine; Fig. 2 is a vertical cen tral longitudinal section of the machine, on a plane parallel with Fig. 1; Fig. 3 is a view look ing at the right-hand end of the machine, as 30 shown in Fig. 1; Fig. 4 is a perspective of the com bined carriage bed and motor housing; Fig. 5 is a vertical cross-section through the gear hous ing, as indicated by the lines 5-5 on Fig. 2; Fig. 6 is an elevation of a pipe threader which may be employed, and which is shown in section in Fig. 2. Brie?y, the entire machine comprises a bed ID, having a hollow standard 55, housing a reduction gearing and carrying a driven chuck 20. A motor .40 3d controlled by a switch ‘H3 is mounted on the bed and connected with reduction gearing within the housing l5; a supplemental bed 4!! carried by the bed It! houses the motor 3!] and supports a slidable carriage 8B, which carries the tools. The tools shown comprise a threading device 9!] and a cutter Hill. Mounted on the side walls of the supplemental bed 40 are removable containers 12!! for receiving the waste oil. These various parts will now be described in detail. The bed II] is a ?at member, shown suitably coredv on its underside for lightness, and the combined gear housing and chuck standard [5, as shown, is integral with the bed except as to a removable end plate l6 normally bolted in place. At the top, this standard I5 is formed into a semi face of the chuck. The motor has its armature shaft 3| connected by a coupling 32 to a shaft 33 journalled in bearings mounted in the adjacent face of the standard I 5. Shaft 33 is shown as having a pinion 34 meshing with an idler gear 35, which carries the pinion 3t meshing with a second idler 31, carrying a pinion 38 engaging main gear 25. This makes a direct train of spur gearing fromlthe motor to the chuck, providing the desired reduction. Surmounting the motor is a peculiarly formed casting 4B, which operates to house the motor and also support the carriage. This casting is shown in perspective in Fig. 4i. It comprises four pads or feet 4! adapted to be bolted to the bed, two feet on each side being connected by a vertical web or side wall. At their upper edges the walls 42 extend outwardly as at 43 and then curve in wardly and upwardly to form roof 5|. This roof also curves downwardly at its ends and is thus a shallow dome or “turtle-back.” At one end this turtle-back‘ unites with a horizontal por tion 53. The horizontal ?oor portion 53 slopes downwardly from the center as indicated at 515 to cause oil, etc. to flow freely toward the sides of the casting; at its outer edge the horizontal floor 53 terminates in an upwardly curving ?ange 55 which guides oil and chips toward the sides of 45 the casting. Suitable brackets 45 extend from the turtle-back upwardly and are arranged to support horizontal ?at strips 4'5 (Figs. 1 and 3) which provide a slideway for the carriage. A suitable transverse web 47 serves to brace the 50 tuctle-back and prevent oil from ?owing for wardly of the‘front carriage supports 45. It will be seen from Figs. 1 and 2 that the casting 40 above described protects the motor, entirely covering it above and at the front and 55 2,137,762 2 back, as well as at the right-hand end of the machine, where the side walls 42 are connected by a transverse web or end wall 48, Fig. 3. The web 48 has an opening to allow access to the motor, but this may be closed by a cover plate, if de sired. At the other end the casting 40 is open for the purpose of ventilation. It will be noted that the inner or left-hand end of the casting 40 is spaced from the up 10 right housing I5 to provide for ventilation. The controlling switch ‘I0, Fig. 1, is secured to the transverse plate of the standard I5 between such standard and the end of the casting 40 and is electrically connected with the motor so that the 15 latter may selectively rotate in either direction. The carriage 80 is of the usual type, and rests on the guides 46 of the supplemental frame and is held thereto by suitable gibs 8| (Fig. 3) ex tending beneath the overhanging edges of the 20 guides. As shown in Fig. 1, this carriage may be of the ‘form shown in Patent No. 2,079,179, re ferred to, having upright posts 82 which carry, on the side toward the chuck, the threading de vice 90, and on the opposite side, the cutter I00. 25 These parts may, if desired, be of the form shown in the prior patent mentioned. As shown here in, they will be briefly described later. Suitable means are provided for moving the carriage lengthwise of the bed. The means 30 shown comprises a centrally downwardly-facing rack 85, which meshes with pinion 86 on a shaft vided with a pair of bayonet slots I25 adapted to receive respective headed pins I26 secured to the side walls 42 of the supplemental frame 40, thus facilitating the removal of the reservoirs. The inner walls of each reservoir underlie the horizontal portion 43 of the frame 40, the outer edge of which depends slightly as indicated in Fig. 4, at 52, thus insuring the draining of all oil into the reservoirs. The used oil, together with the discharged 10 chips and dirt will pass downwardly from the turtle-back 40 into the receptacles I20. From time to time the receptacles will be removed and the dirt and chips removed therefrom, then the relatively clean oil may be poured from the re 15 ceptacle, for instance, into a supply reservoir I30, mounted on a post I3I on the carriage. From this. reservoir oil is discharged to the tools through a pipe I35, controlled by a cock I36. It will be seen from the description given that 20 by employing the peculiar supplemental frame shown and described, I have thoroughly pro tected the motor, and allowed provision for ven tilation thereof. At the same time, I have pro vided means for readily retrieving the waste oil 25 and restoring it to condition for using. The re— movable receptacles enable ready transfer of the oil to the supply reservoir without the necessity 81 journalled with bearings 61 carried by the of employing a pump, thus rendering the whole 30 machine less liable to get out of order. I claim: 1. In a power driven tool, the combination of’ guide bars 46. A suitable hand wheel 88 fur nishes means for rotating the shaft to shift the 35 carriage toward and from the chuck, as desired. engagement with a pipe mounted in the chuck, 35 Referring to Fig. 6, 90 indicates a suitable ring-like frame carrying radial chasers 9| to coact with the pipe A. The ring 90 is shown as having diametrically opposite horizontal ears 40 92, which seat in ways in the carriage posts and may be held in place by tapered pins 93. As shown, the ring frame 90 carries a face plate 95 having internal cam grooves coasting with pins on the chaser. The ring carries a crank 96 45 operated by hand lever 91 and adjustably con nected by a link 98 to the cam plate. Accord ingly, the throwing of the lever may spread the chasers or return them, if desired. The cutter is illustrated in the drawings as of 50 the form shown in the patent referred to, although another form of cutter may be used, if desired. Briefly, in the form shown, the cutter comprises a slidable block IOI (Fig. 3) mounted on one of the carriage posts and carrying a cut 55 ting wheel I02. Opposed to this is a slidable block I04 carrying a pair of rollers I05. Rods I06 attached to the block I04 pass slidably through ears on the block IOI to a head I01. Rotatably mounted in this head is _a screw-threaded shaft 60 screwing into the block IM and carrying on its free end an operating hand wheel I09. The turning of this hand wheel may therefore force the blocks toward each other or cause them to recede, as desired. 65 In Figs. 1 and 3, I20 indicates open top con tainers which are removably supported by and rest against the respective side walls 42 of the supplemental frame 40, the inner side edges of the container coming beneath the overhanging 70 horizontal walls or beads 43 of the frame. Chips and oil dropping from the tools slide off the turtle-back 5| and drop into the containers. Each container may be provided with the usual removable screened basket, not shown. 76 The inner wall of each receptacle I20 is pro a chuck, a motor for driving the chuck, a car riage over the motor adapted to carry a tool for a housing over the motor and beneath the car riage having a gutter for receiving oil, and a re ceptacle carried by the housing, said housing be ing adapted and arranged to divert oil falling 40 thereon into said receptacle. 2.
