CHARLES WICKSTEED, OF KETTERING, ENGLAND.
SAWING-IVIACHINE.
To all whom it may concern:
Be it known that 1, CHARLES \Vronsrnnn, a subject of the King of England, residing at Kettering, in the county of Northampton, England, have invented certain new and useful Improvements in Sawing-Machines, of which the following is a specification.
This invention relates to sawing machines. The use of mechanically-guided hack-saws for cutting metal is well known. Such saws have been applied to the cutting of metal articles held on a stationary fixed table, and this application has been found to be of considerable practical value. Moreover, combination machine tools have hitherto been proposed in which a circular neck Work holder was adapted to turn in sockets so as to secure a larger range of angular adjustment for the work. The present inventor having found that existing hacksawing machines with fixed work-tables possess limitations due to the fact that the table is fixed has invented the combination with a saw or a plurality or gang of saws and guiding-devices therefor of a work-supporting table which as the characteristic feature of this invention is such that it can adjust the work in relation to the saw to any position desired, for instance angularly in different planes or to different levels as Well as to different angles, and in addition, or instead if desired, to different positions horizontally by means of a slide or crossed slides. In the said combination any convenient construction of table can be used provided it is capable of adjusting the work as aforesaid. For instance the well-known type of adjustable table commonly used on the upright standard of a reciprocating shaping-machine can be employed.
In the accompanying drawingsFigure 1 illustrates in side elevation a construction of improved hack-sawing machine according to this invention, comprising an adjustable table of the shaping-machine type; Fig. 2 illustrates in side elevation and Fig. 3 in end elevation a detail, hereinafter described, of the machine illustrated in Fig. 1, the scale of Figs. 2 and 3 being larger than that of Fig. 1.
Specification of Letters Patent.
Application filed June 2, 1911.
Patented July 22, 1913.
Serial No. 630,829.
With reference first to Fig. 1 the base 13 has vertical guides G upon its front face. (in these guides travels the table, which is in three parts T T T and can be moved up and down along the guides G by the adjusting-screw S engaged with the part T The companion part T of the table can have upon it clamping-jaws or devices of any usual or convenient type capable of holding the work firmly. It is pivotally mounted on the part T and is adjustable in relation thereto by a screw S which gears into a toothed quadrant Q 011 the said part. The screw S is used to adjust the part T in re lation to the part T about a horizontal axis which is perpendicular to the front face of the machine.
The cross-slide or part T of the table slides transversely across the front face of the machine on a guide on the part T being movable along this guide by means of the horizontal cross-screw S A hack saw H is mechanically reciprocated more or less horizontally above the compound table T T T in a plane perpendicular to the front face of the machine. The saw is supported in the following way. A gauntree formed of two rods L, a bar L and a third rod L is pivotally supported at B upon the standard B. The rods L, seen most clearly in Fig. 3, carry a cross-head H slidably mounted on the rods L so as to be free to reciprocate back and forth thereupon. The cross-head H has a drooping tail-like portion H to which a connecting rod R is attached, the other end of the connecting rod being in engagement with a crank pin G on a crank disk O. The crank disk is carried by a shaft A mounted in the support which carries the pivot B of the gauntree L L The shaft A, by means of an eccentric A and eccentric rod A operates hydraulic means (which form no part of the present invention) by which, through the rod A the gauntree is tilted slightly in a clockwise direction on each return stroke of the saw H so as to raise the teeth of the latter from the work on the return stroke but so as to allow the saw to fall on its work again dur ing the forward stroke.
Convenient means are provided whereby the saw frame H which is reciprocated in company with the cross-head H can be adjusted relatively to that cross-head and held firmly upon it nearer to one or the other end of it. i
The means of adjustment in the illus trated example shown in Figs. 2 and 3 in greater detail than in'Fig. l consist of a slider H adjustable endwise in guides which it fits in the cross-head H Bolts H project fro-m the slider H through longitudinal slots H in the cross-head and serve to clamp the saw frame I-I borne by the slider H in any position to which it may be moved endwise. This adjustment affords a convenient means of locating the limits of travel of the saw relatively to work clamped upon any part of the table T The saws H can be adjusted laterally (as viewed in Fig. 3) with relation to one another so that cuts can be taken simultaneously side by side in a piece of work, the saw holders H being slidably mounted on transverse rods G and provided with clamping screws G to enable this to be done.
The cross-head H slides upon rods L forming one end of a lever L, L pivoted to the frame of the machine at B. Upon the portion L of the lever L, L is fixed a rod L parallel with it and on the rod is a weight V which can slide along it and be fixed upon it in any chosen position by means of the set screw W. This weight can be shifted to one side or the other of the fulcrum B so as to vary the pressure with which the saw bears upon the work.
It will be seen that the sawing machine herein described is capable of executing a great variety of work with accuracy and despatch. It is capable, for example, when the two saws shown in Fig. 3 are separated from one another, of performing work, which ordinarily would have to be carried out in a milling machine with straddle mills, with greater rapidity than that which would be attained in a milling machine. This is owing to the fact that portions of material which would have to be entirely removed in the form of cuttings by the milling machine, can be removed as a block by making cuts with the saw which meet one another. Owing to the way in which the saw or saws are arranged to sink steadily in their kerfs, together with the means whereby the work can be accurately presented to the saw or saws, work such as that which has just been referred to can be carried out in a manner which heretofore has been quite impossible.
lVork firmly clamped on the part T 3 of the table can be presented to the saw at various levels and various angles and can be shifted across the face of the machine by the cross slide T lVork can be easily and rapidly carried out in a machine thus fitted that could not be carried out except with difficulty and delay on a machine having a table not thus adjustable.
