Letters-Patent No. 114,019, dated April 25, 1871..
IMPROVEMENT IN MACHINES FOR MAKING STRAP-'HINGIES-` The Schedule referred to in these Letters Patent and maklng part of the same.
To all whomtt may concern;
Be it known that I, WILLIAM' J. LEWIS, of Pittsburg, in the county of Allegheny and State of Penn Sylvania, have invented a new and useful Improvement in Machine for Making Strap-Hinges; and I do hereby declare the following tu be a full, clear, rand exact description thereof, reference being had to the accompanying drawing making a part of this specification, in which- I Figure 1 is a plan view of my machine; Figure 2 is a sectional elevation in the line x x,
I Figure -3 is a` detached perspective view ofthe shears and bending devices;
Figure 4 is a side elevation of the rear or further 'side of the machine; and
it it is di'icult to make the hinge of good finish, with a good weld, and without burning the iron.A
By my improvement4 I obviate all these defects, make the hinges more rapidly with less labor, and produce a good and durable article.
To enable others skilled in the art to make and use my improvement, I will proceed to describe its construction and mode of operation.
The frame f may be of any suitable or convenient construction.y l
On it, by suitable bearings, I mount a driving and cam-shaft, g, to which power may be applied by a crank or in other known suitable way.
In suitable bearings h in the opposite end of the machine is a bending-spindle, It, on one end of which is a pinion, l, and ou its opposite end is an anvil or rest, m, the upper face of which latter is a little below and a little outside of the center of the spindle h.
v This bending-spindle It is made hollow through apart of its length, and in such hollow part a mandrel-stem, a', is arranged, with a connection to a grooved collar, b, which is arranged ou the spindle h, the spindle being mortised, as at t', so `that room may be made for snch connection aud for the movement of the same in sliding the mandrel-stem a' in and out.
The mandrelstem a carries a mandrel, a, at its outer end of the size'to be given t0 the eye of the hinge.
'The outer end of the spindle la is also mortised, as at c', lso as to make room for the bending and swagiugblock a", which is rigidly attached to the stem a.
The reciprocating or 'out-and-in motion to begiven to the stem a', mandrel a, and block a is secnred'by means of a lever,l d, which is pivoted toa xed fnlcrum, d, has a fork, c,.at one end to enter the groove of the collar b, and at its other end ar'pin, c', which enters a spiral groove, c, in the driving-shaft g.
The spindle his caused to rotate alternately each way by means of a segmental wheel, a, which is piv oted to some fixed support, and which meshes into the pinion Z.
It is operated either way by a shaft, k, which leads from the cam-yoke 11 in which yoke are arranged two cams o o', so that, acting alternately against opposite faces of the yoke, they shall cause the desired motions to be imparted to the segmental -wheel n.
The yoke 1) is supported by sliding ways p' or in other suitable manner. Y
The connections of the shaft It are adjustable at each end by means of the slot n in the segmental wheel n and the slot la in the opposite end of the shaft It where it joins the cam-yoke p, for purposes obvious to those `skilled in the art.
Ou the side' of the mandrel a opposite to the anvil m are arranged the shears s s', with cutting-edges of. the form to be given to that end of the hinge-strap which is to be bent or folded over.` Y
The stationary knife or shear s is set in a frame, g, which is adjust-ably, by means, of slots o', attached to the frame f.
The other knife or shear s is set in a rocking head, q', which latter is pivoted in the frame q, and to which the desired motions are imparted by the use of a shaft, t, leading from a cam-yoke, y', in which operates the cam y.
This connection is also adjustable, as shown at t.
The yoke y is supported by the sliding way w.
On the anvil or rest fm, flushwith the .end of the spindle It, is astripper, c.
The operation is then as follows The devices being in the position shown in Iig. 1, the blank z unbent is fed in along the face of the anvil fm, between the mandrel a above and the block a," below, in between'the shears any desired distance for trimming. l
By the cam g/,yoke y', and shaftt the shears s s are put in operation to trim the blank. Then, by
the cam o, yokep, shaft k, segmental wheel n, and pinion l, the spindle It is caused to revolve with a quick stroke, the result of which is that the block a" carries the end z of the blank over, folds it around the maudrel a, and lays it down on the body'of the blank back of the eye, and brings it to the form illustrated iu iig.
at the end of the strap.
5; the devices then beingv` in the position shown in iig. 3. Then, by the spiral groove c and lever d, a` throw is given to the collar b, which carries-back with it the stem a', mandrel a, and block a, and the hingeeye is stripped off the mandrel by means of the stripper c.
By continuing the revolution of the driving-shaft g the devices described are all brought back to the original positions, their motions being reversed in every case.A f
lTheY shears are opened; the spindle h is by the segmental wheel n revolved back, and the mandrel a and block tv/"lare thrown out again, so as to be ready for a new feed. f In this way the work goes on continuously and with greatrapidity.`
The object of the slot n in the segmental wheel fn -is tp vary the length of throw of the bending-block a,
- This obviously will make the male half of 'the hinge.
I also use 'the machine to bend the end of a blank to form a hinge-eye in that class of hinges in which the folded end a is not required, but merely an eye "metallic straps generally.
It will be observed that Jie anvilm performs not only the function of a guide when the blank is being fed in, but also its proper functionthat oi'an anvil, onto which the block a, swages or forces down the two folds or layers of the strap, so as to give a per fectly-shaped and wellformed eye.
VVhat'I claim as my invention, and desire to secure by Letters Patent, is
1. Thev combination of rotating spindle h, mandrel; a, stem and block a and a", the anvil in, and mech-` for the purposes set forth.
2. The devices of the previous claim, in combination with a stripper, e, substantially asdescribed.
3. In combination with the devices set forth in first clause of claim, the shears s s', substantially as and furthe purposes set forth.
4. Theisegmental wheel n, slotted, as at n', so as to be capable of a variable length of stroke, in combination with the spindle h, arranged substantially as' described, for causing thev lat-ter to revolve alternately in opposite directions.
In testimony whereof I, the said WILLIAM J. LEWIS, have hereunto set my hand.
'WILLIAM J. LEWIS.
