    PREFACE.

    Table of Contents

    Line

    Every successful engineer is a born inventor; indeed the daily work of an engineer in practice largely consists in scheming and devising from previous experience new and improved processes, methods, and details for accomplishing them, and for simplifying or cheapening old forms of machinery and the work they produce, to enable him to successfully compete with others, who are perhaps as ingenious and enterprising as himself.

    In the work of designing machinery the draughtsman has to rely mainly on his memory for inspiration; and, for lack of an idea, has frequently to wade through numerous volumes to find a detail or movement to effect a particular purpose. Hence, as a rule, every man’s work runs in a groove, his productions generally having the stamp of his particular experience and training clearly marked upon them.

    In the course of twenty-five years of such experience, I have found the want of such a volume as the present, and endeavoured to supply the deficiency in my own practice by private notes and sketches, gathered promiscuously, until the difficulty of selection and arrangement became so apparent that I began to classify them, as they exist in the following pages. A few weeks of unusual leisure have enabled me to complete this work and amplify it by numerous additions, and it is now presented in the hope that it will be found of equal service to others engaged in the head-splitting, exhausting work of scheming and devising machinery, than which I can conceive of no head-work more wearing and anxious, Several valuable works have already found numerous users, and there is no lack of admirable collections of memoranda, rules, and data for designing and proportioning the various constructive details of machinery; but, as far as I am aware, there is no work in existence which aims at the same purpose as is attempted in the following pages, viz. to provide side by side suggestive sketches of the various methods in use for accomplishing any particular mechanical movement or work, in a form easily referred to, and devoid of needless detail and elaboration. A sketch, properly executed, is—to a practical man—worth a folio of description; and it is to such that these pages are addressed. For the same reason it has been deemed undesirable to add to the various sketches any rules or tables relating to strengths or dimensions, which may be found in numerous well-known volumes.

    Any suggestions or additions will be entertained and gratefully acknowledged.

    THOMAS WALTER BARBER.

    Additions

    see pages 245-335.)


    Section 1.—ANCHORING.

    Table of Contents

    1. Rope pulley anchor—a car which grips by sinking its wheels in the soil; employed for ploughing tackle.

    2. Anchor plate—buried in the ground below a mass of masonry—for attaching guys, tie rods, &c. Sometimes a frame, or plate, laid on the ground and ballasted, is the method used.

    3. Screw mooring, screwed into the ground.

    4. Heavy stone sunk in the ground and having a ring attached; or a mass of concrete, similarly placed, used for guy ropes, tie rods, and foundation bolt attachments.

    5. Grapnel.

    6. Mushroom anchor.

    7. Double fluke anchor.

    8. Martin’s patent anchor, with swivelling flukes. Several other patent anchors are modifications of this.

    Stakes, with or without flanges, vertical or horizontal, are sometimes employed, the flanges taking the cross strain of the ties, &c. Fencing posts, gate posts, tree stakes, and tennis poles are of this class.


    Section 2.—ADJUSTING DEVICES.

    Table of Contents

    For adjustment by Screws, see Section 78, and by Wedges, see Section 36, These are the commonest appliances employed. For Cams also, see Section 9. For adjusting Pedestal Brasses, see Section 46.

    For adjustments by keys, cotters, &c., see Section 37. See also Nos. 251, 269, and 297.

    9. Split cone sleeves and set screw adjustment for a revolving standard, or similar detail, where there is much wear or great accuracy is required in the revolving bearing.

    10. Centre-line adjustment for lathe headstocks, &c.

    11. Variable curve adjustment; used in compass planes, instruments for drawing arcs of circles, &c.

    12. Vertical shaft footstep adjustment; employed on millstones, horizontal grinding mills, &c., to regulate the space between the grinding surfaces. See No. 261.

    Plate 1

    Larger plate.

    13. Side screw adjustment for injectors, jet pumps, &c.

    14. Levelling adjustment; can be used with either 3 or 4 screws: for telescope and level stands, theodolites, &c.

    15. Horizontal central adjustment for footsteps, &c.

    16. Slotted link and lock nut for adjusting angle of a lever.

    17. Disc and ring with partial angular adjustment by a screw and nut; used for screwing dies, self-centering chucks, &c. The nut and bearing of the screw have allowance for swivelling.

    18. Pin and hole adjustment for a lever or similar detail.

    19. Wedge bearing for locomotive horn plate guides, slide bars, and similar parts subject to wear.

    20. Right and left-hand screw and wedge adjustment for roller bearings, &c.

    21. Adjustment for wear used
