GAVIN SHEARER HAMILTON, OFMOTHERWELL, AND THOMAS rHoMson; on Home TOWN, SCOTLAND.

T 0 all whom it may concern: 1

Be it known that we, GAVIN SHEARER HAMILTQN and THOMAS Tnortso v, subjects of the King of the United Kingdom. of

Great Britain and Ireland, andresiding, re;

spectively, at lVlot-herwell, Scotland, and Holytown, Scotland, have inventeda certain new and useful Improvement in Axle Mills, of which the following isa specification. A v

This invention relates to axlemills of the type comprising superposed relatively repressed and rolled to the desired configuration.

The present invention is characterized primarily by the feature that the plates are divided into three sets of which the intermediate set is first brought into operation to form the middle portion of the axle whereupon the external sets are brought into operation to form the ends of the axle.

A further feature consists in the provision of means for imparting feeding movements concomitantly to the upper and lower external sets of plates such means comprising power operated screw-and-nut feeding mechanism for the upper external sets and feeding wedges interconnected therewith for the lower external sets.

In the drawings which illustrate the invention Fig. 1 is an end elevation, Fig. 2 a side elevation and Fig. 3 a plan. 1 v 1 The axle mill shown comprises three sets of plates 1, 1 2, 2 3, 3 in superimposed relation and guided in a frame 4 to perform rectilinear reciprocatory movements in opposite directions.

y The

plates

1, 2 and 3. are connected to move simultaneously lengthwise by

lugs

30, 31 projecting inwardly from the plates2, 3 into engagement with vertically disposed

slots

32, 33 in the plate 1, the arrangement being such that the

plates

2, 3 are free to move vertically of the plate 1. Similarly, the plates 1*, 2 and 3 are connected to move simultaneously lengthwise, the

plates

2, 3 being formed with lugs 30", 31 and the plate 1 being formed with

slots

32, 33 come the plate 1 is adapted guides AXLE MILL.

sponding in function to the

lugs

30, 31 and

slots

32,33; l e

The plates 2, are providedwith eyes 3 1, 35 and the plates 2?, 3? are provided with eyes 34?, 35? connected respectively to rods, 36, 37, 38. 39 which, in turn are connected at 36337", 38 and 39 to levers 40, 41 rigidly secured to a rock-shaft 42 journalled in pedestals 4:3, 4-4. Connected to the levers 4O, 41 are rods-45, 16 which are constrained to reciprocate by any convenient source of power. The

rods

45,46 are caused to re ciproca-te continuously so that the

plates

1, 2 and 3 reciprocate continuously and the plates 1 2? and 3 reciprocate continuously in the directions opposite to those of the

plates

1, 2 and 3.

The adjacent faces of the sets of plates are spaced to accommodate the iron or steel bar 5 and are shaped to conform with the contour of the finished axle. Means hereinafter described are provided for imparting feeding movements to the intermediate set.

to form the middle portion of the axle and then for imparting feeding movements to the external sets to form the ends of the axle. It will be seen that the bar 5 is constrained to rotate between the plates and is pressed and rolled to the desired configuration.

In the operation of the mill, the intermediate set 1, 1*"- is first moved vertically and thus brought into operation to form the middle portion of the axle, sets 2, 2 and 3, 3, meanwhile reciprocating idly then the

external sets

2, 2, 3, 3 which are preferably interconnected are moved vertically and thus brought into operation to form the ends of the axle.

The plate 1 is immovable vertically and to be fed towards the bar 5 to form the middle portion of the axle by means of screws 6 in screw-threaded engagement with afixed bar 7 and pressmg on the guide 8 for the plate 1, the screws being simultaneously rotatable by motor driven worms 9 and worm wheels 10.

For imparting feeding movements con comitantly to the upper and lower external sets of

plates

2, 2 8, 3 whereby to form the ends of the axle there are provided screws 11 engaging the bar 7 and pressing the 12 for the

plates

2, 3, and connected motor driven worms 13 engaging worm wheels 13* secured to the screws 11, the sets To reduce friction, rollers 19 are inserted:

between the several guides and the relative plates whereby to form a roller track.

It will be seen that, due to division of the plates into sets only certain parts of the length of the bar need be compressed at any time during the rolling process, the parts of the bar being thus allowed to swell or' lengthen as required according to thework being done on the centre or on the journal portions of the bar.

1. An axlemill comprising, in combination, three sets of superposed plates mounted for relative reoiproca-tory movement and presenting operative faces spaced to accommodate the bar to be treated and shaped to conform with the contour of the finished axle and means for first imparting feeding movements to the intermediate set of the three to'form themiddle portion of the axle and then imparting feeding movements to the external sets of the three toiorm the ends of the axle.'

2. An axle mill comprising, in combination, three sets'of relativelyreoiprocatory upper and lower plates presenting operative faces spaced to accommodate the bar to be treated and shaped to conform with the contour of the finished axle, means for imparting feeding" movements firstly to the intermediate set of the three so as to form the middle portion of the axle, and means for imparting feeding movements secondly to the external sets of the three so as to form the endsof the axle, said lalst named means comprising screwand-nut; mechanisms for feeding theupper sets and Wedges for feeding' the lower sets. j
