Abstract: 741,515. Making helical paraffin scrapers for oil wells. TRIPPLEHORN, D. R. Aug. 17, 1953, No. 22614/53. Classes 83 (2) and 83 (4). Bending.-In the manufacture of helical paraffin scrapers for attaching to oil well sucker rods, lengths of metal bar stock B, Fig. 6, with each end E of one edge bevelled, are forced through a die comprising an inner cylindrical member 16, Fig. 4, having a helical groove 16a on its periphery, and an outer sleeve 15 forming a wall for the groove, the bars being disposed with the bevelled edges disposed inwardly towards the axis of the die whereby the latter forms the bars into helices S, Fig. 1, and bends the ends thereof so that when attached to the sucker rod their inner surfaces E<SP>1</SP>, Fig. 7 (not shown), taper away from the sucker rod and their outer surfaces taper towards the sucker rod. The helices are subsequently heat-treated. The bar is preferably of spring steel which is initially annealed. It is first sheared into lengths B and the ends bevelled. The lengths are fed into a guideway 9 within which they pass between adjustable feed rollers 6, 7 having knurled peripheries which grip the bars and force them through the die 15, 16. The inside diameter of the helices is less than the diameter of the sucker rod to which they are subsequently attached. The helices emerging from the die are collected by a catch rod 18 which causes a number of them to be nested so that they can be removed as a group. The feed rollers are driven through gears and chains. Alternatively a hydraulic ram may be used to force the bars through the guideway and die.

Title: Improvements in or relating to templet-controlled machine tools
IPC: B23Q35/121
Filed: 1958-07-15
Abstract: 865,644. Copying-lathes; machine-tool details. ERNAULT-BATIGNOLLES, H. July 15, 1958 [July 23, 1957; Jan. 23, 1958], No. 22657/58. Class 83 (3). A copying-lathe, copy-milling machine or the like, comprises a carriage 104 movable parallel to the axis of a workpiece 145 and carrying a toolslide 141 movable towards the workpiece, and a templet-holder 155 rockable by a crank 157 about an axis parallel to the work-axis. The templet 152 is engaged by a feeler 144 actuating a valve 189 to control an hydraulic piston 187 attached to the tool-slide 141. If an electric power failure occurs, an electromagnet E1 allows a spring R2 to move the feeler 144 in the tool-withdrawing direction. An adjustable stop 191 limits the withdrawal movement of the tool by engaging a stop 192, and also engages a switch M1 controlling rapid-return of the saddle. The holder 155 is secured by a bolt 19 to the crank 157 in a position adjusted by a screw against a graduated scale. The crank is held by a spring against a fixed stop 159. The crank can be angularly-adjusted by adjustable stops 161 on a drum 162, indexed by a rack-and-pinion operated by hydraulic means 165, to swing the templet outwardly for taking roughing cuts. Oscillation of the crank 157 is damped by a dashpot 164. The saddle 104 is traversed on guides 102, 103 by a screw 113 or, for quick traverse, by an hydraulic piston 105. Indexed with the drum 162 is a disc carrying screws 177, which can be adjusted to vary the stroke of each traverse of the saddle which carries a stop 176. When the stop 176 engages a screw 177, a valve V3 and a switch M4 are actuated to index the drum 162 and to withdraw the tool. A disc (not shown), on a shaft 175 carries selector-means for skipping one or more of the roughing-cuts. The lead-screw 113, engaging a gear 114 in the carriage, is rotated from the lathe headstock drive by a shaft 121, driving through gearing which can be selected or locked by electromagnetic clutches EM1 to EM4. The gear 114 is normally locked to the saddle by a spring- operated clutch 116 and, for manual traverse of the saddle, it can be rotated by a hand-wheel 130. Traverse of the saddle rotates a control drum T2 by a quick-pitch screw 195. A second control-drum T1 is indexed with the disc 162. The drums carry dogs to control traverse speeds through the electromagnetic clutches EM1- EM4, and to control spindle rotation. To produce a rapid-return movement of the saddle, switches M7, M11 are actuated by dogs on the drums T1, T2 to energize electromagnets E2, E3. The magnet E2 releases the clutch 116, allowing the gear 114 to freewheel in engagement with the traverse-screw 113, and the magnet E3 moves the screw 113 a small distance axially to actuate a valve V2 and cause rapid movement of the piston 105. Specification 808,976 is referred to.

Title: Rotary drilling machine, more especially a rotary rock-drilling machine
IPC: E21B3/035
Filed: 1952-09-16
Abstract: 727,603. Drilling-machines. SIEMENS SCHUCKERTWERKE AKT.- GES. Sept. 16, 1952 [Nov. 24, 1951], No. 23253/52. Class 83 (3). A drilling-machine, more particularly a rock-drilling machine, is provided with two operating-gear stages, one of the stages transmitting a torque proportional to the bearing-force on the drill in addition to a small constant moment and the other stage transmitting a supplementary moment exceeding this proportional value, so that together, through the two stages, the torque necessary for drilling is transmitted from the spindle to the drilling shaft. The drill 10, Fig. 1, is carried at the end of a rod 9 supported by a bearing 8 on an elongated frame. The drill rod is driven by a shaft 12 through a gear-box 13 from an electricmotor 17 which also drives the feed-screw 14, supported below the drill, and terminating in a thrust bearing and supporting-head 36, 7, respectively. The drive from the motor 17, preferably, passes through a gear-box 15, to the feed-shaft 14 which has a pinion 21, Fig. 3, splined thereto and driving a wheel 22 loose on the drill-shaft 12. A thrust bearing 20 is arranged at the back face of the wheel 22 and a clutch surface 32 at the front face. A long nut 25 on the feed-screw 14 in the gear-box 13 carries an integral pinion 23 which engages with a gear-wheel 24 coaxial with the drill shaft 12. The wheel 24 and a clutch part 31 have quick-pitch threaded bores which engage a threaded part of the shaft 12. An integral extension 19 of the wheel 24 engages a collar in the clutch part 31 and the latter is secured through a torsion spring 30 to a collar 33 secured to the shaft 12. A further collar 26, Figs. 3 and 4, fixed to the portion of the shaft 12 within the gear-box 13 forms part of a unidirectional clutch or brake which prevents reverse rotation of the shaft 12 and is used during the withdrawal motion of the drill, which thus takes place at high speed. The machine provides a differential feed movement in the forward direction dependent upon the resistance to penetration of the drill and a quick return movement on reversal of the driving motor. The return movement is also automatically stopped if the resistance to withdrawal of the drill exceeds a predetermined value.
