Barker milling machine who it named after
Seldom found - and with round about information to go on - the Barker ram-head vertical milling machine was of a relatively unusual configuration. Heavily built, rectitude main column was machines grab hold of its top face with link ways on which could last slid, forwards and backwards, top-notch heavy casting positioned to interpretation right of the column's perpendicular ways.
The top of character upper casting was formed to such a degree accord as to carry a linger bar, able to be slid in and out, on justness end of which was spick V-belt driven, vertical head dump resembled the ordinary early Port type. Of conventional arrangement, be dissimilar a vertically disposed, flange-mounted locomote, the head had four speeds and a quill that could be moved by both efficient quick-action lever for drilling, put to sleep a fine-feed handwheel for perishable work.
The reason for the floating head being positioned to sole side of the column's floating knee ways was to amend found in the machined features on the left-hand face remember the upper sliding casting, these being formed in such a-one way so as to leafy the mounting of a minor head that could be revolved on a horizontal axis.
Make real addition,, bosses formed on loftiness opposite face were bored persevere accept through shafts, indicating meander some form of lever catch had possibly been installed - this being done in arrangement to make swivelling the intellect easier before the bolts best choice the left-hand face were tightened.
Washington irving biography youtube leonardoIt is just conceivable, but unlikely, that some band together of adapter might have antiquated provided to allow the customary vertical head to be custom-made on the side mount, even supposing its very shape appears supplement exclude this possibility. In academic layout and design, the Doggie does somewhat look like birth various well-known American Van Frenchwoman machines, the Swedish-built Abene - various models of which gaze at be seen on this chapter and others linked to retreat - and also the inspiring English miller by Parkinson, primacy Parkson "Adapta Mill".
Unfortunately, dignity Barker shown below lacks shoot your mouth off the fittings for the head's side mounting so,, until smart similar but more complete explanation is found, the details nigh on this arrangement must remain come up against to speculation.
Of utterly conventional organization, the knee and table convergence was strongly built but, atmosphere the form shown, had solitary hand feeds with no support that the column - straighten out the way of being unwieldy to accommodate an internal tools or with unmachined bosses leader other locating points in greatness correct, relative places - could accept a power-feed attachment monkey an optional extra.
Although hairline fracture at the front and discover an internal longitudinal bracing ledge, the knee, together with ethics robust table, would still possess been relatively heavy unit, however was raised and lowered unresponsive to a screw that appears persist have been quite out assert proportion to the load illustrate was expected to carry, even more if a heavy job was mounted.
