Letters Patent No. 94,122, dated August 24, 1869.
IMPROVEMENT IN MACHINES FOR MAKING BOLT-HEADS.
- l The Schedule referred to in these Letters Patent andmaking part'of the same.
HOP-O To all persons to rwhom these presents may come Be it known that I, MERRICK DJMARY, of the city. and county of XVorcester, and State of Massachusetts, have invented a new and useful or improved Machine for Heading Bolts; and I do hereby declare the same to be fully described in the following specification, and represented in the accompanying drawings, of which- Figure l is a front elevation;
Figure 2, a side view;
Figure 3, Ya longitudinal section; and
Figiue 4, a transverse section of it'.
Figure 5 is a top view of the bed and the movable die or boltholder. A The nature of my invention consists' in combining with the bed, the bolt-holder, the hammers, and the upsetting-mechanism, a mechanism for gradually raising the bed while the bolt is being headed.
Also, in combining therewith a mechanism forcausing the sudden depression of the bed after the heading of the'bolt may have been completed.
Also, in the combination of the movable die or boltblank carrier with the bed, by a peculiar holdingmechanism, as hereinafter explained.
In the drawings-' A denotes the bed, which, in form, is the frustum of a wedge.
'lhis bed rests with its longer 'side upon'that of a similar frustum or wedge, which is supported upon and by two parallel guides orv rails, C C, fixed to the upper surface of a base-plate, D.
Thereris another pair of such guides, E E, fixed on the upper surface ofthe-wedge B, and made to enter -corresponding grooves formed in the bed A.
l1`u1thermore,the said bed A has two ears or projections aa extended from opposite sides of it, and into vertical 'grooves l) b of a frame, F, elevated on the base-plate.
Within this frame, and applied toit so as to be capable of sliding ve1'tically,'is the upsetter G, which is operated by an eccentric, d, fixed on a holizontal shaft, e, the said shaft heilig duly supported by the frame F.
A yT-pieee embraces the eccentric, and is jointed to the upper end of the upsetter.
Around the shaft and a pulley," g, fixed on a'shaft, 7l., a cross-band, i, plays.
The shaft h carries `a pinion, i', to work in a rack, k, fixed to the side of the wedge B, the purpose of the belt, the pulley, the shaft, the gear, and rack, being to feed the wedge B along underneath, and so as to gradually elevate the bed. l
The said bedA hasy an elongated passage, Z, made down through it, and over a similar passage, m, extending down through the wedge B.
Resting on the upper part of such passage, and within a circular rebate, n, formed in the bed, is the bolt-die or carrier H, which is ilanged, asv shown at o, to rest on the upper surface of the bed.
This bolt-die holds the bolt s while it is iu the act of being headed.
From the flange of the said die, two arms, p q, extend in opposite directions, and, by being moved under two cleats,'r` s, serve, with such cleats', to holdv the bolt-die in place upon thebed.
Each of the arms, where it goes underneath its cleats, is bevelled or wedged laterally, so as to fit closely thereto.
'lhere is pivoted to the frame F, four curved levers or hammers, I I, K K, each having an adjustable steel die or hammer heat, t, fixed to its lower part.
To the upper ends of these levers,`toggles or connections, L L, M M, areixjointed, such toggles being also jointed to the upsetter.
The joints of one pair of the said togglcs, and the 'upsetter, are arranged over those of the other pair, so
that when the toggles of the iirst pair are horizontal, those of the other will be at an acute angle with each other.
This arrangement causes the pairs of hammers, through the action ofthe npsetter and toggles, to operate alteinatelyand not simultaneously on the bolthead.
By the connection of the hammer-levers withthe upsetter, by means of the toggles or connections L L,
-M M, the said levers will be moved or Yswung 011 their fulcra, by the upsetter operating with such toggles, the same causing two of the 'hammers to approach each other, and strike and compress the bolt-head at once on two opposite sides, after which they will recede from it, and the other twov hammers will `move up to, and strike and compress the bolt-head on its 'other two opposite sides.
The upsetter strikes down upon the head and fiattens it, or spreads it out or upsets it, the head being gradually raised until it may be completed Vby the upsetter and the successive blows of the hammers.
We combine with the machine means L,or mechanism for causing the sudden depression of the bed, immediately after the completion of the bolt-head, the same being in order to enable `the bolt-die or carrierto be removed, and the bolt to be discharged from'it, and another bolt -to be put in the place of it.
To this end, we attach to the elevating-wedge, by means of a line, t', going over a pulley, u, a weight, r, which, as soon as' the bolt-head may be completed, and the pulley g be unclutched from its shaft, will suddenly draw back the wedge, and cause thedepression of the bed.
lo enable the wedge to be retracted, the slid pnl ley g should be applied to the shaft h, s o as to be oapable of being slid endwise thereon, both toward and away from a clutch, qv, xed on such shaft, the pulley heilig 'provided with recesses to receive the clutch.
The pulley may be moved up to o1' away from the clutch, by means' of a'forked lever, suitably applied to a groove, y, in the liub of the pulley.4
2L Also, in combination with the bed A, the boltholder H, thel upsetter G, the hammers I I, K K, and the Wedge, or mechanism'for raising the bed, as and for the purpose described, a `mechanism for causing 'the snddendepression of the bed, immediately 'after the heading of the bolt' mayhave taken place, such mechanism being not only a Weight, fu, connected to clutch, w, or means of engaging and disengaging the driving-pulley g of the pinion-shaft h-with such shaft, as described.
