Definitions

  • the socalled straggler carriage may assume a horizontal displacement over the slideway of the frame; the plate intended to receive the work may assume a horizonal displacement perpendicular to the preceding movement with reference to the straggler; the spindle-carrying carriage may move vertically.
  • the spindle may slide in parallelism with its own axis along this carriage.
  • control levers or flywheels are controlled by means of control levers or flywheels and are transmitted to the parts considered by suitable transmissions actuated by a supply of driving power.
  • My invention has for its object to remove this difliculty and it covers to this end a luminous signalling device allowing the operator of the machine to ascertain at every moment the direction of the movements produced.
  • This device consists in principle in a board on which is drawn a diagram of the machine, for instance the boring machine; the" parts capable of moving are shown on it and to each of them corresponds a transparent arrow giving out the directions of displacement. Behind said arrows are located electric bulbs, the illumination and extinction of which are determined by the movements of the control parts.
  • the boring machines and generally the machine-tools to which the invention is applicable, are provided with a surfacing plate, i. c. with a circular plate carried: concentrically with a tool such. as a spindle and provided with a slide carrying a tool which slide assumes a radial movement with reference to the axis of the spindle so as to make the tool draw a spiral on the surface worked upon and rectify thissurface.
  • a surfacing plate i. c. with a circular plate carried: concentrically with a tool such. as a spindle and provided with a slide carrying a tool which slide assumes a radial movement with reference to the axis of the spindle so as to make the tool draw a spiral on the surface worked upon and rectify thissurface.
  • two special luminous arrows are adapted to give out the direction of displacement of the surfacing slide. Behind these arrows are placed corresponding lamps which are lit: or extinguished at the required moment.
  • a lamp which has for its object to warn of any risk of meeting between the spindle and. the slide on the plate.
  • This lamp is lit under the action of a novel device comprising two longitudinal grooves provided on the sheath of the spindle and engaging projections adapted to actuate contacts when they reach one end of the corresponding groove.
  • One of these contacts sends current into the last mentioned lamp for warning of the danger of meeting between the spindle and the slide on the plate.
  • the other contact breaks the current feeding the motor if the limits of displacement of the spindle in one direction or the other are reached.
  • Fig, 5 shows separately the diagram of the electric connections.
  • Fig. 6 shows a modification corresponding to the case of machine provided with a surfacing plate.
  • Fig. 7 shows the indicating board in said modification.
  • Fig. 8 a corresponding general diagrammatic view showing the connection of the electric parts withthe mechanical parts.
  • Fig. 9 is a simplified wiring diagram.
  • T designates the straggler.
  • the work-carrying table adapted to assume a horizontal movement perpendicular to that of the straggler.
  • the tool is placed in the spindle holder B carried by the spindle-holder carriage 0 adapted to assume a vertical movement along the slideways H.
  • the indicating board Ti forming the object of the invention is mounted on the spindle-holder carriage C. Next to it lies an indictor 10 controlling the cutting speeds.
  • At M is located the electric motor actuating the tool, said motor serving also for actuating the different mechanical parts.
  • b designates the change speed levers of the spindle; in the drawing are shown two levers actuating several sliding gears B1, B2, B3, B4 (Fig. 4) providing the various possible speeds of the spindle.
  • c (Fig. l) designates the levers for adjusting the advance motions, i. e. those which provide for modifications in the magnitude of any one of the advance motions.
  • d is the change speed and advance motion lever; it allows reducing the speed of the spindle and increasing the advance motion and con versely, increasing the speed of the spindle and decreasing the advance motion.
  • the selection of the longitudinal displacement movement of the straggler, of the transversal motion of the table and of the vertical motion of the spindle holder carriage is performed by means of the gear wheels contained in the box BE (Fig. 3) arranged on the bench.
  • the control is obtained by means of a single part A12 passing out of the spindle-holder carriage.
  • ,f (Figs. 1, 3 and 4) designates the advancereversing lever which through its transmission Pf may reverse the direction of movement of all the worms and consequently of the advances.
  • g (Fig. 1) is the selecting lever for the advances, which allows obtaining slow or rapid advances or hand operated advances.
  • FIG. 7 designates the cross bar for engaging and operating the spindle, i. e. engages the latter directly and controls the hand operated advance.
  • Figs. 1, 3 and 4 is the selecting device for the parts to be displaced. It acts on the part contained in the box BE. If it is raised, it lowers through the agency of the lever PL a sliding gear Bs (Fig. 3), which actuates the worm LV. If it is horizontally displaced, it drives through an arm bp a sliding gear B which actuates the worm LL for the longitudinal displacement of the straggler or the worm LT for the transversal displacement of the table.
  • FIG. 2 Referring to the detailed View showing the indicating board (Fig. 2) it is apparent that on its front side, is drawn a sketch illustrating diagrammatically the machine. The principal clements given out hereinabove appear in said sketch. To each movable part correspond two transparent arrows LB, LB-LT, L'TLV, L'V having opposite directions. A diagonal line A subdivides the diagram into two parts; the arrows above this line give out the movements which set the parts further from the operator and the arrow underneath the movements nearing them.
  • knobs l, I and 2 At the lower part of the board are located three knobs l, I and 2; the two former serve for controlling the passage of current into the motor for making it rotate in either direction; the two 4 arrows 1 and I show through their illumination the direction of operation.
  • the third knob 2 controls the stopping.
  • the knobs l and I when they are depressed close the circuit of the relays shown at AV and AR in the diagram of Fig. 5; when one of these relays receives current, its armature illustrated diagrammatically by the dot and dash line L displaces the row of usual movable corresponding contacts 4a, 4b, 4c, and M which close difierent circuits as will be seen hereinafter. It closes also a complementary contact 5 or 5 arranged in the circuit of a transformer 6 feeding the indicating lamps 1 or I.
  • Fig. 3 and Fig. 4 show how the levers described hereinabove act on the electric circuit producing the illumination of the lamps of the indicating board; they show also the kinematic connection between said levers, the power supply and the parts controlled through their agency.
  • the lever e shows a part cc (Fig. 4:) forming a cam acting on a depressable element of a contact CB inserted in the circuit of the lamps LB, LB corresponding to the spindle.
  • the lever acts in a similar manner through a cam fc (Fig. 4) on the contacts Co and Cc, one of said contacts being adapted to be opened and the other closed according to the desired series of displacements.
  • the lever 9 (see Fig. 1) may be brought into three different positions through horizontal displacements thereof. In each of said positions, if it is lowered vertically, it switches the current ed the motor by acting on the contact CS (Fig. 5).
  • the lever p which may assume a double movement, as appears clearly in the general diagram, produces the following effects: When this lever is at its dead point, all the kinds of movements which are signalled on one side of the diagonal are possible and all the arrows are illuminated. But if this lever has been placed in a selection position only the corresponding arrow remains illuminated.
  • this lever :0 When this lever :0 receives an elevational movement, it acts through a slope Rp and a roller (Fig. 4) on a contact CV. If a horizontal movement is imparted to it, it acts through a cam Cp on the contacts CL, and CT. The location of these contacts in the electric circuits appears more clearly in Fig. 5.
  • the control system a (Figs. 3 and 4) acts through a cam K7 on a contact C9 controlling the lamp LE.
  • the first step consists in acting on either of the knob I or I, which sends current into one of the relays AV or AR.
  • the latter closes its contacts, consequently the motor M is started in either direction according to the knob actuated. For example, if the knob is acted upon the circuit of relay AV is established from the input lead I02 through wire I M, winding AV, wire I05, the switch controlled by knob I, wire I06, closed switch CS and line wire IUI.
  • the transformer 5 receives current and it feeds either of the two lamps LAV 01' LAR of the corresponding arrows l or I.
  • the illuminated arrow indicates the direction of rotation of the motor.
  • the second step consists in placing the lever f in a position corresponding to the direction of the desired displacement of the part which is to assume a movement, which part may be the carriage, spin'dlezor the like. According tov the position given to this llever .7 .all the lamps LL, LV, LB (Fig. 5) or all the lamps LL, L'T,T;T -iV, LB are illuminated :i. e. :all the lamps above the diagonal or all those underneath.
  • Said lever e as it actson the contact ,piece CB providesior the illumination of the lamp LB .or IIB corresponding to either direction of operation of the spindle B when the lever considered is called to act on said spindle or else, when it acts on one of the three other members .of the machine considered, such .as one of the three carriages, said levere provides for the illumination of either of the lamps IL, or IJ'L, 'L'I or LT, LV -or UV corresponding to the direction of displacement .of -the part considered.
  • the "fourth operative step is subdivided into two according as to whether it 'is desired to produce the displacement of the spindle or that of the carriages. If the spindle .is to receive the movement. the cross-bar is engaged so as to produce the closing of switch C7 andthe illumination of the lamp LE. In this case lever E will have beenoperated so as to act upon switch "CB breaking contact between contact members 1 21 and I 22 thereby cutting off previously lighted lamps LL, LT. LV (LL, LT. L'V') which 'are thus extinguished, and establishing contact between contact members I23 and 124 thereby allowing current to continue to -pass through lamp LB (LB) and thereby allowing this lamp to remain lighted.
  • the machine is supposed to be provided with a surfacing plate PS comprising a slide CS.
  • Fig. '7 illustrating the corresponding luminous indicating board, it is apparent that the latter comprises the same arrangement as in the preceding form of execution with the i addition of two further arrows LS and US arranged on either side of the diagonal line 6 and indicating the direction of displacement of the surfacing slide.
  • the lever c has been modified as shown in Fig. 8 for controlling the two above supplementary lamps. It may assume four positions. Three of these positions are the same as in thepreceding case i. e. one of them corresponds to the displacement of the tool carrying spindle B by means of the rack LB, (Fig.8) while the second produces the movement of the box BE through the rod A12 and the third is that which produces the displacement of the surfacing slide by means of the gearwheel E39.
  • the fourth position corresponds to the simultaneous operation of the spindle and of the slide which is obtained by simultaneously engaging the sliding gear E20 with the pinion E21 controllin the spindle and with the pinion E23 controlling the shaft A14 and the gearwheel E39.
  • diiferent positions acts on different contacts. It carries on its pivotal axis .a sort of plate provided at its periphery with bosses adapted to act on thrust members controlling the contacts.
  • bosses ec acts first on the thrust member of a contact CLPB which, when the lever e occupies the position for which the spindle B moves, establishes a circuit lighting the lamp LB or the lamp L'B.
  • a boss cc acts on the contact CLP and closes it, the boss ec continuing to hold the contact CLPB closed.
  • the contacts CLPB, CLP and CLTP of Fig. 9 being closed, the lamp LB or L'B is lit at the same time as LP or LP which reveals the simultaneous progression of the spindle and of the plate.
  • Another boss e acts on the thrust member controlling a contact CLVT inserted in the circuit of the lamps LL, LL, LT, L'T, LV, LV, which give out respectively the movement of the straggler, of the table or of the vertically moving carriage.
  • boss e0 may act only on the contact CLP inserted in the circuit of the lamps LP and LP indicating the progression of the plate alone when the latter is operative, without the spindle being caused to advance.
  • the lever f for reversing the advances (second operative step) is provided with two bosses f f by means of which it acts on the contacts CSA or USA which lights the lamps above the diagonal or the lamps underneath same.

  • I may obtain the longitudinal movement of the straggler, the transversal movement of the table or the vertical movement of the carriage. In this position, all the corresponding arrows are illuminated, but if it is placed in a selecting position, onl the corresponding arrow remains illuminated.
  • the contact on which it acts when raised is shown at CLV (Figs. 8 and 9). When it is displaced horizontally, it acts on the contacts CLL and CLT (Figs. 8 and 9).
  • the lamp LE of the preceding case is omitted. But a lamp LTP is added (Fig. 8) in the case of machines with a surfacing plate. This lamp which is of a very apparent colour, for instance red, is illuminated when the slide of the surfacing plate is actuated and the spindle is sufficiently out for it to be possible for the spindle to contact with the slide, which it is necessary to avoid.
