Definitions

  • rlhis invention essentially consists in arranging on the slide or rest of the lathe or cutting machine, a particular tool support, adapted to slide in an endwise direction, and a guide supporting device, also mounted to perform an endwise sliding motion, which latter device acts on a pattern or model secured to a iXed part of the lathe frame and urged against the same by means ofi a spring, both sliding devices being suitably linked together in Order that the movements of, one of the same will cause a corresponding ⁇ movement of the other device.
  • the invention further has for object a device of the above kind in which the thickness of the article to be turned or cut may be reduced or increased at will in relation to the thickness of the pattern or model, or the length of said article in relation to the length of the pattern, or both may be varied at a time, all such objects being obtained automatically and in a reliable manner, without requiring the aid of expert operators or turners, whereby not only a considerable saving in the cost of manufacture may be obtained, but also the respective Objects may be turned or vcut withinl a much lesser period of time.

  • Figure 13 is a side view which illustrates vthe operation'of said device.
  • Figure 14 illustrates the manner of applying a rotative ⁇ cutter to the tool supporting device.
  • Figure 15 is a similar view to Figures 1 and 2 whichy illustrates this invention as applied to ther turning or cutting of objects of different sections, either variable or constant and provided ornotwith designs ⁇ or'letters in relief or bas-relief.
  • Figure 16 illustrates a modiication of the pattern support inV the foregoing ⁇ arrangement which causes the pattern to follow the slide in its movement; according' to this arrangement, objects of a length equal to that of the klathe-may be turned by using a short pattern.
  • Screw Figure 1T illustrates a modified construction of the guiding device for the case when a positive pattern is to be used.
  • Figure .i8 illustrates the tool supporting ⁇ device provided with a series of tools, for operating on several objects in series
  • Figure 19 is a side elevation of the same device.
  • the pattern ormodel is carriedl means V by a support 207 adapted to slide on the member 2l which in turn is mounted to perform a sliding' movement in a direction normal to that oi: the suplgiort 21') on the block suitably secured to the base 'trame of the lathe.
  • rlhe center support 7 is formed integral with a rod 23 on which is mounted a spring 2d which bears on a ii'xed collar for the purpose ot constantly urging the guide center against the surface oit the pattern or model. as will be readily understood.
  • the pressure must be controlled in accordance with the class olE material under treatment and in accordance also with the depth or the work to be per'torn ed. all ot which is obtained by 'varying the tension o' the spring or by the mechanical devices he after to' be described. 26 indicates a handle Ytor imparting longitudinal movement t tion to the lathe.

  • the pattern i9 is in this case also placed on the sliding member 20, in the endwisevdirection or 'the lathe. The member 20 slides transversely on the member 2l and the latter travels in an endwise direction on the guide l.. It screw l2 is used to secure the engagement of the dead center 29 Awith the object 27 to beturned.
  • Figures-3, -l and 5 illustrate details ot the construction of Athis preferred embodiment ceive the head of the pin 5, which pin is secured .in position by means of afnut 35", 'for the purpose of varying the length of At the centre of said plate 3 at the underside thereof are termed-'two grooves 86 and 36a, of swallow tail cross section and arranged at right angles with regard to each other, by means of which said p'lateis allowed to slide along awcorresponding.guide :formed 1n the slide .2. In the top surface of the plate are required.
  • the lever 4 is .provided with a somewhat elongated hole 39 within which moves a pin 40, provided ywith a sleeve 41, saidy pin being formed integral with the sliding center-support 7 and placed below the bridge 9, the opposite end of said lever extending below the bridge 10.
  • the bridges 9 and 10 are secured by: means of the screws 42 to the respective sliding members 7 and 3.
  • said rod To the said support 43 is secured the rod 23, above referred to; said rod carries at its end a fixed eye or ring 25, secured after the manner of a clamp between two nuts 46 on the end ofa screw' 45 secured to theplate 3, so that by varying the position of said nuts, the pressure exerted by the aforesaidspring 24 on the slidingcentersupporty 7, may be increased or decreased as 47 is a screw operated by means of the handle 26 and adapted to turn in a bracket 49 formed integral with'the plate 3 and' which at its opposite end is threaded into the slide; this arrangement allows of lvarying theposition of the plate-3 in relation'to the said slide and causes the same to approach to, or recede from'th'ev object to beturnedv and the pattern or model as the turning operation progresses, thereby adjusting the pressure applied to the' work. Said screw may be placed in one direction or another, according to the position occupied by the plate with regard to the rest or slide'. In order'to change the position of the screw 45, the plate 3 is formed
  • Said support 20 is provided at its lower face with a swallow-tailed grooveA which engages with a corresponding ⁇ guide formed on- 'the yupper part ofthe member 21, being -secured in position by means'of the screw 51.
  • the supporting member Y21j in turn,'is mounted to slide -on the r ⁇ slide block 22, in a similar way, being conveniently secured in position by means of the screws k52.
  • the said slide block 22 is secured to thebase frame l of the lathe by means of a clamp 53, which, is perforated at its oppo- ⁇ Vvsite ends 'for' engagement with' threaded studs ⁇ S4-Wand 55 carried respectively by the block 22 and frame 1, the clamp being secured on said studs by nuts 54 and 55 respectively.
  • the block 22 is thus rigidly secured to the frame 1.
  • the position of the pattern 19 with regard to the 'centre guide y15 may be adjusted constantly and at will according to lthe requirements ofthe work and to suit the pattern .as the operation proceeds.

  • theftool-carrier 67 also is capable of sliding movement in a longitudinal direction, corresponding to the length of ythe work to be turned.
  • These movements which may be obtained in several ways, are produced in the present instance as follows:
  • the slide member 66 is provided with two lateral stops 76 with which engages a fork 75, formed integral with a lever 73, which is provided with a longitudinal groove Y74.
  • To the lower part of the said lever is linked the end 76 of a rod 77 the opposite end of Vwhich is pivotally connected at 78 to the slide or rest.
  • the lever 73 is pivoted, intermediate its ends, to a stud 72 carried by a bracket 71 which is Vrigidly secured to the bed'frame of the lathe, the vertical portion of lthe bracket being also provided with a slot similar to the slot 74, whereby the stud may be secured to said bracket at any point in the length of its slot andv of the slot 74 in the lever, by means of a collar 72a fixed on the stud and a nut 72b threaded on the end of said stud as clearly shown in F ig. 13.
