IMPROVEMENT IN GUIDE FOR ARDING-Iill@INE.V

Be it known that I, JOHN BACHELDER, of Norwich, in the county of New London, and State of Connecticut, have invented a new and improved Adjustable Guide for Carding-h/Iachines'; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others lskilled in the manufacture or use of this class of machinery to make and use the same, reference being had to the accompanyingv drawings, forming part of this specification, in which- Figure is a side View of my improved guide, with a supporting-hase, @attached for the purpose of exhibition. When attached to carding-machines, the pins or studs Zi are set in the frame, near each end of the guidebars, and this base, a, is dispensed with.

Figure 2 is a longitudinal section, parted vertically through its centre; and

Figure is a longitudinal plan section, parted horizontally through'the centres of the screws h and z'.

Similar letters of reference indicate like parts.A

The object of my invention is to provide lan adjustable guide for laying the slivcrs being fed to cardingmachines evenly over the surface of' the cylinder, which I accomplish by -makingmy guide in two or more parts, o 3 ahove the other, so arranged that either can'be set at the point desired simply by turning a screw, thus enabling the operator to deliver the slivers where they are required to cover thc'whole surface, instead of delivering it in ridges, as by the ordinary methods.

It is constructed and arranged as follows: The bar c2 represents the lower part of the device, with vertical slots e entirely through it, near each endfor the supporting and guiding-studs Z In, which are set into the frame of the ending-machine, near each end oi' the guidebars. If more than two guide-bars are used, they would all be like this7 except the top one, c, in which the vertical slots corresponding with e, do not extend quite through the bur. Each bar is perforated with elliptical holes, n, at proper distances, and of sufficient size toallow the slivers to pass freely, a portion through each bar. The num'ber of holes is determined bythe width of the vcardingnliachines when applied to second breakers, and hythe number of rings on thevdolier, when applied to the finishing-card. Through oneend ofeach har is a bolt7 g, set on a horizontal plane with the screw 7L, which passes through it, having no thread at this place, but is threaded at the end and works in the stud b. Through the bolt g is itted the screw t', having a smooth, straight end,Y fitting the groove turned in the surface of' the screw It, which causes the bar to move when the screw i is turned. v

lTo place the guide-bars in position to operate, they arev placed across the frame ofu the carding-machine, parallel with and near to .the feed-rolls, the ends upon'the frame, 'the studs b b having been previously set vertically in the frame of said carding-machine, passing through the slots c in the lower bar or bars, and into the slots or mortises of the top bar c. The screw his then vput in its place, working in the stud b, as in a nut. The small screw z'is then set in its p'lace, the smooth end extending into the groove cut in the body ot' the screw 7i,y between the thread and its head. It-is'then complete.

What I claim as my invention, and desire tov-secure by Letters Patent, is v 1. 'lhe combination of two or more adjustable guide-bars, constructed substantially as described andfor the purpose set forth.

2. The arrangement of the screws 7 and t' with the holt g, for the purpose specitied.`l

JOHN BACHELDER.
