MACHINE FOR, EXPANDING SHEET METAL.
Patented Mar. 7, 1922.
Application filed August 27, 1920. Serial No. 408,424.
T 0 all whom it may concern Be it known that we, IIARRY Siimron' and HARRY BOOTON, subjects of the King of Great Britain, residing at York ll lansion, York Street, lVestminster, London, lingland, have invented new and useful improvements in Machines for Expanding Sheet Metal, of which the following is a specification.
It has before been proposed to expand a slitted metal sheet by means of a machine having two divergent series of pairs of roll.- ers or two diverging pairs of chains which grip the edges or selvages of the sheet and feed them through the machine whilst coinpelling them to travel along divergent paths so that the sheet is expanded.
We have found that it is unnecessary to employ for gripping the selvages of the sheet feeding or travelling means, such as rollers or chains.
According to this invention we employ a pair of fixed divergent guides eachvof which has throughout its length a slot along which the selvages of the sheet can travel and which is provided with a shoulder behind which the upturned selvage or extreme strand of the sheet engages so that the selvage cannot be pulled out of the slot, but must follow the slot to the end of the guide. In some cases the sheet proceeds through the machine, as it leaves the slitting rollers and the rollers which displace the selvages out of the plane of the rest of the sheet, without any further assistance, but in other cases we may provide at the further; ends of the divergent guides a pair of pin wheels to engage the selvages of the expanded sheet and to draw it through the machine. The divergent guides may be either straight or stepped in such a way that the central portion of the sheet is expanded first'and that subsequently portions on each side of the centre are released from the guides and expanded successively.
In the accompanying. drawings which illustrate the invention Figure 1 is a side elevation, Figure 2 is a plan thereof, Figure 3 is a side view showing the rolls, guides and expanded sheet, Figure 4 is a detail end view showing a sheet fully expanded, and pin wheels, and Figure 5 is a detail. end view of the rolls for deforming the selvage. Figt res 6, 7 and S are sections on the lines Ala- A,- B--B, G -G, respectively fiignre 3,
Figures 5, 6, 7 scale.
1 are selvage deforming rolls in bearings 14 and driven through spur wheels 15. Each roll has at one end an inwardly bevelled segmental flange 2 and at the other end a segmental flange 3 bevelled outwardly at the same angle as the flange 2, the flanges 2 and 3 of one roll being adapted to cooperate with the flanges 3 and 2 of the other roll.
When a metal sheet 4 which has previously been slitted in any suitable manner so as to form parallel strips connected by junctions of uncut metal is passed through the rolls 1, the selvages 5 are bent at intervals at right angles to the plane of the sheet and are then also doubled or bent back in the opposite direction as is clearly shown in Figures 5 to 8.
After passing through the selvage rolls 1, the sheet 4 enters a guide 6 having in it a slot 7 extending the width of the sheet 4, and a groove 8 at each end of the slot 7 along which the selvages 5 can travel.
On leaving the guide fithe sheet 4 enters a pair of fixed divergent guides 9 each of which is formed of a top and bottom plate arranged a suitable distance apart to form a slot 10 extending throughout its length along which the selvage 5 and part of the sheet 4 can travel; formed in the outer plate of each guide 9 is a groove 11 the inner face of which forms a shoulder behind which the upturned selvage 5 of the sheet 4 engages so that the selvage cannot be pulled out of. the slot 10 but must follow the slot 10 to the end of the guide 9.
The guides 9 as shown in the drawings are tapered and have steps 90 along their inner edges and are at their wider ends adjacent to the selvage rolls 1 of such width that practically the whole of the sheet 4 is covered up or enclosed by the walls of the slots 10 so that only the central portion of the sheet 4 is expanded, portions on each, SlCleof the centre of the sheet being subsequently released from the slots 10 in the guides 9 and expanded successively until at the end of the guides the whole of the sheet 4 between the selvages 5 has been expanded, see Flgures 3, 4, 7 and 8.
At the end of the guides 9 is arranged a pair of inwheels 12 having chain wheels .120 driven by chains 13 actuated by sham and 8 all being to a larger Wheels 130 on the same axes as the selvage rolls 1. The pin Wheels 12 engage the selvages of the expanded sheet 4 and draw it through the guides.
Though We prefer to use pin Wheels 12 to draw off the sheet 4, these are not necessary.
What We claim is 2- 1.
