Improvements in Machines for Planing Metal.
I, WILLIAM WILSON HULSE, of Ordsal Works, Salford, in the County of
Lancaster, Engineer, do hereby declare the nature of this invention to be as
follows:-
My invention relates to side planing machines in which a tool slide is carried
by a projecting arm or slide having at right angles thereto a longitudinal slide,
the whole being traversed along a suitably formed slide bed by means of a longi-
tudinal non-rotating screw with rotating nut, or rack with rotating pinion, the
nut or pinion being actuated through gearing by a strap or electric motor.
One or more such longitudinal slides with projecting arms and tool slides may be
employed on the slide bed with suitable mechanism arranged for cutting either
separately or in combination and in the same or in opposite directions. The slide
bed.is planed true on the upper surface and grooved in front to receive the table
or tables for supporting the work.
Each longitudinal slide with its projecting arm and tool slide is provided with
a sliding bar arranged to travel with the longitudinal slide and to be arrested or
stopped near the termination of each of the cutting and return strokes of the longi-
tudinal slide by coming in contact with one or other of two stops that are adjustable
longitudinally. The sliding bar has attached to it an incline piece which, owing
to the continued motion of the longitudinal slide after the stoppage of the sliding
bar, actuates a double lever and oscillating shaft carried by the projecting arm of
the longitudinal slide. On the inner end of the oscillating shaft is a pair of bevil
wheels which actuates a longitudinal back shaft, geared by other bevil wheels to
a vertical shaft for the strap lever reversing mechanism; or each carriage could
be provided with its own driving and self reversing mechanism. Hand motion for
starting or stopping the machine is obtained by means of a rocking shaft which
can be operated from the front at any part of the longitudinal traverse and is in
connection with the reversing mechanism.
On the other end of the oscillating shaft is a lever provided with a pawl adapted
to actuate a ratchet wheel geared to a pinion fixed on the end of a screw which
extends along and within the projecting arm for imparting a feed motion to the
tool along the projecting arm.
For imparting a vertical feed to the tool, the ratchet wheel is geared to a second
pinion fixed on the end of a shaft which extends along and within the projecting
arm and is connected with a ratchet action to the vertical screw (which for this
purpose is tubular) by means of a shaft which passes through the same. Or, the
vertical feed may be imparted by either the longitudinal back shaft or the rocking
shaft by a lever applied to either one or the other, sliding with the longitudinal
slide and acting through a connecting rod, universal joint and ratchet action.
When it is desired to cut both wavs in the same machine, two adjacent longi-

page_text: tudinal slides with their projecting arms are brought together and connected,
their respective tool slides being face to face, and a suitable distance apart.
In such cases one of the reversing arrangements is suspended for the time being.

Improvements in Machines for Planing Metal.
We, JANE HULSE, of the Grove, Withington, Manchester, in the County of
Lancaster, JOSEPH WHITWORTH HULSE, of Ordsal Works, Manchester aforesaid,
and FRANK SYKES, of Edgeley Fold, Stockport, in the County of Cheshire,
executors of the last will and testament of William Wilson Hulse of Ordsal Works,
Salford, in the County of Lancaster, Engineer, do hereby declare the nature of this
invention and in what manner the same is to be performed to be particularly
described and ascertained in and by the following statement:-
My invention relates to side planing machines in which a tool-slide
carried
by a projecting arm or slide having at right angles thereto a longitudinal slide,
the whole being traversed along a suitably formed slide-bed by means of a longi-
tudinal non-rotating screw with rotating nut, which is actuated through gearing
by a strap.
One or more such longitudinal slides with projecting arms and tool-slides may
be employed on the slide-bed with suitable mechanism arranged for cutting either
separately or in combination and in the same direction or in opposite directions.
The slide-bed is planed true on the upper surface and grooved in front to receive
the table or tables for supporting the work.
In order that the invention may be properly understood I will in describing it
refer to the accompanying illustrative drawings wherein Figs. 1 to 4 inclusive
represent a side planing machine according thereto in which the reversing is
effected by means of strap-forks; Figs. 1, 2 and 3 being respectively a front eleva-
tion, a plan, and an end elevation thereof, and Fig. 4 a partial end elevation of the
machine with the tool-slide and its vertical feed-mechanism removed.
Figs. 5 to 9 inclusive represent a side planing machine according to this inven
tion that has two longitudinal slides or carriages provided with mechanism for
cutting separately in opposite directions; Figs. 5 to 8 inclusive being views similar
to Figs. 1 to 4 respectively, and Fig. 9 being a plan of a detail.
In each case 1 is the slide-bed of the machine: 2 is a longitudinal slide or
carriage, 3 its projecting arm, and 4 a tool-slide; 5 is a work-table.
Each longitudinal slide 2 with its projecting arm 3 and tool-slide 4 is provided
with a sliding bar 6 arranged to travel with the longitudinal slide 2 and to be
arrested or stopped near the termination of each of the cutting and return strokes
of the longitudinal slide by coming into contact with one or other of two stops 7
that are adjustable longitudinally in the slide-bed 1. The sliding bar 6 has
attached to it an incline-piece 8 which, owing to the continued motion of the
longitudinal slide 2 after the stoppage of the sliding bar 6, actuates a double lever 9
and an oscillating shaft 10 carried by the projecting arm 3 of the longitudinal
slide 2. At the inner end of the oscillating shaft 10 there is, in the example shown
in Figs. 1 to 4, a pair of bevel wheels 10 which actuates a longitudinal back
shaft 10, geared by other bevel-wheels 10° to a vertical shaft 10d for the strap-

page_text: fork reversing-mechanism 10° of the driving shaft 11, which is connected by
means of bevel-wheels 12 and 13, a cross shaft 14, and a bevel-wheel 15 with the
traversing-nut 16 on the stationary screw 17. Each carriage may, however, he
provided with its own driving and self reversing mechanism, as in the example
shown in Figs. 5 to 9 inclusive, wherein the two carriages 2 are operated by a
common shaft 11 that always rotates in the same direction and at the same speed
and which is provided for each carriage 2 with a coupling 11 having a feather
and groove connection with the shaft 11 and adapted to couple therewith one or
other of two bevel-wheels 12 and 12b that are mounted in arms 2 of the slide 2
and respectively constantly engage in other hevel wheels 13 and 13b both secured
on the shaft 14: the coupling 11" is at the termination of each of the cutting and
return strokes, disengaged from one of the wheels 12 and 12 and engaged with
the other thereof by means of an arm 11b secured on a shaft 11° carried by the
projecting arm 2 and provided with an arm 11, in the outer end of which is a
plunger 11 pressed outwards hy a spring 11 and provided with a wedge-shaped
outer end that engages in notches 11 in a bar 11h, which, each time the shaft 10
is operated by the incline-piece 8, is slid parallelly to the screw '17 by an arm 11.
which is fixed on the shaft 10 and strikes against one or other of two buffers 11'
mounted to slide in casings 11 secured to the bar 11h and pressed towards the
arm 11 by springs 111 (see Fig. 9), the arrangement being such that at each
stroke of the arm 11 the bar 11h is moved to such an extent that first of all the
springs 11 in the arm 11d is compressed by the bar 11h as the latter passes over
the plunger 11° and that finally the second notch 118 comes into such a nosition
that the wedge-shaned end of the plunger 11 is forced into it by the spring II',
whereby the lever 110 is caused to alter its angular position so as to oscillate the
shaft 11° and the arm 11.
Hand-motion for starting or stopping the machine, or each carriage, as the case
may be, is obtained by means of a rocking shaft 18 which can be operated from the
front by means of a handle 18" at any part of the longitudinal traverse and is in
connection with the reversing mechanism. in the machine shown in Figs. 1 to 4
heing provided with a toothed wheel 18 that engages with teeth made in the
sliding bar 6, and in that shown in Figs. 5 to 9 being a continuation of the
shaft 11°.
On the other end of the oscillating shaft 10, in the example shown in Figs. 5
to 9, or on a shaft 10 connected therewith by toothed wheels 108 in that shown in
Figs. 1 to 4, is a lever 19 provided with a pawl 20 (see Figs. 1 and 5) adapted to
actuate a ratchet-wheel 21 geared to a pinion 22 on the end of a screw 23 which
extends along and within the projecting arm 3 for imparting a feed-motion to a
tool along the projecting arm. In the machine shown in Figs. 1 to 4 the wheel 21
is geared directly to the pinion 22, there being only one tooth-holder 4; but in
the machine shown in Figs. 5 to 9, as there are two tool-holders 4 on each arm. 3.
there are two screws 23 and consequently two pinions 22 and the wheel 21 is geared
to these by means of a second pinion 24.
For imparting a vertical feed to the tool, the ratchet-wheel 21 is, as in the
example shown in Figs. 5 to 9, geared through the pinion 24 to a shaft 25 which
extends along and within the projecting arm 3 and is connected by
bevel-wheels 26, 27, and 28 and a ratchet-action 29 (see Figs. 5 to 8),
to the vertical screw 30 (which for this purpose is tubular), of each
tool-holder 4 by means of a shaft 31, which passes through the same. Or,
the vertical feed may, as shown in Figs. 1, 2, and 4, be imparted by the longitudinal
hack shaft 10 by means of a lever 32 applied thereto, sliding with the longitudinal
slide 2, and acting through a connecting rod 33, a universal joint 34, and a
ratchet-section 35.
When it is desired to cut both ways in the same machine, two adjacent longi-
tudinal slides 2 with their projecting arms 3, arranged and provided with
mechanism as shown in Figs. 5 and 6, are brought together their respective tool-
lides, which are face to face, being placed at a suitable distance apart,

page_text: Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed I declare that what I
claim is:-
1. A side planing machine wherein the reversing of the traverse of a longitudinal
slide or carriage, traversed by means of a non-rotating screw and a rotary nut, is
effected by a sliding bar arranged to travel with the slide or carriage and to be
arrested near the termination of each of the cutting and return strokes thereof
by one or other of two stops, the said sliding bar being provided with an incline-
piece which, owing to the continued motion of the slide or carriage after the
stoppage of the sliding-bar, actuates a double lever and an oscillating shaft and
thereby reverses the rotation of the traversing-nut, substantially as described.
2. In a side planing machine, mechanism for reversing the traverse of a longi-
tudinal slide or carriage constructed, arranged, and operating substantially as
herein before described with reference to and shown in Figs. 1 to 4 inclusive and
in Figs. 5 to 9 inclusive of the drawings annexed.
3. Side planing machines constructed, arranged, and operating substantially
as hereinbefore described with reference to and shown respectively in Figs. 1 to 4
inclusive and in Figs. 5 to 9 inclusive of the accompanying drawings.
