' ATTACHMENT FQR SAW -GINS- SPECIFICATION forming part of Letters Patent No. 778,071, dated December 20, 1904. Application filed June 11,1904. Serial No. 212,156.

T (1, whom it may concern.-

Be it'known that I, STEPHEN W. POWER, a citizen of the United States, residing at Murfreesboro, in the county of Pike and State of ,Arkansas, have invented a new and useful Attachment for Saw-Grins, of which the following is a specification.

This invention relates to attachments to cotton-gins for removing adhering material from the saws of the same, and has for its object to provide a simply constructed. and efiicient device which may be adjusted relative to the brush-cylinder to cause the latter to act with increased force upon the teeth of the gin-saws and remove adhering particles therefrom. Another object of the invention is to produce a simply-constructed and easily-applied device which serves the twofold purpose of a partition or stop member between the ginsaws and as a means whereby theadhering particles are removed from the same. With these and other objects in view, which will appear as the nature of the invention is better understood, the same consists in certain novel features of construction, as hereinafter fully described and claimed.

In the accompanying drawings, forming a part of this specification, and in which corresponding parts are denoted by like designating characters, is illustrated the preferred form of the embodiment of the invention capable of carrying the same into practical operation, it

1 being understood that the invention is not necessarily limited thereto, as various changes in the shape, proportions, and general assemblage of the parts maybe resorted to-without departing from the principle of the invention or sacrificing any of its advantages, and the right is therefore reserved of making all the changes and modifications which fairly fall within the scope of. the invention and the claims made therefor.

In the drawings thus employed, Figure 1 is a transverse sectional elevation of a portion of a cotton-gin including the gin-saws and brushcylinder with the improved device applied. Fig. 2 is afront elevation with the brush-cylinder removed. Fig. 3 is a perspective view of the improved device detached. Fig. 4 is a sectional plan view, drawn to an enlarged scale,

illustrating the contour in cross-section of the brush -defiecting means and their position with respect to the saw and brushes. The improved device may be attached to any of the various constructions of cotton-gins and similar devices manufactured by making slight and immaterial modifications in the means of connecting the same, but for the purpose of illustration is shown applied to a conventional form of cotton-gin, in which the supportingframe 10, gin-saws 11, mounted on a shaft 12 and separated by the spacer-disks 13, brushcylinder 14:, and breast-ribs 15 are shown in the usual form and in the usual relative positions. The improved attachment comprises a head member (represented as a whole at 16) comprising two plates 17 18, connected together longitudinally and with longitudinal grooves in the opposite edges of the plate 17 one to receive a rod 19, with its ends 20 21 extended through bearings in the opposite sides of the frame 10, and the other groove to re into a crank 24 to enable the rod to be rocked in its bearings in the frame to swing the head 16 to cause the ribs 22 to be moved toward or away from the brush-cylinder, as required.

Some means, such as a set-screw 25, will be employed to hold the rod and its attached head and ribs in any required position.

The widths of the ribs 22 will be suflicient to closely engage the sides of the gin-saws and will present relatively sharp edges constantly to the same, as will be obvious, so that particles of material will be prevented from adhering to the saws. The ribs when thus supported serve the purpose of thepartition ordinarily employed in gins; but in event of the gumming of the saws, as when operating on damp cotton, by simply adjusting the rod 19 by means of the crank 24 the ribs can be forcibly moved toward and in contact with the brush members, With the efiect of distending the bristles laterally and causing them to be forcibly compressed against the saw-teeth and by thus concentrating the action of the bristles of the saws effectually remove all adhering particles. Thus the gin-saws can be very easily cleaned While the machine is running and as often as required and when operating upon dry cotton, which does not gum the saws, the device can be secured in position to serve only as a guard or partition, as above noted.

The device is very simple in construction, may be inexpensively manufactured, and can be readily applied to any of the various forms of cotton-gins manufactured and will be found very eflicient for the purposes denoted.

The parts may be of any suitable material and of any suitable proportions to adapt them to the work required.

Having thus described the invention, what I claim is- 1. In a cotton-gin, the combination with the saws and brush-cylinder, of means for concentrating the action of the brushes on the saws.

2. In a cotton-gin, the combination with the saws and brush-cylinder, of means for defleeting the brush-bristles into contact with the saws.

3. In acotton-gin, the combination with the saws and brush-cylinder, of a plurality of spaced ribs arranged between the saws and having inclined faces for deflecting the brushbristles into contact with the saws.

4C. In a cotton-gin, the combination with the saws and brush-cylinder, of a plurality of ribs \I-shaped in cross-section and extending between said saws, said ribs serving to deflect the brush-bristles into contact with the saws.

5. In acotton-gin, the combination with the saws and brush-cylinder, of a plurality of spaced ribs extending between the saws and, adjustable to a position to coact with said brush in cleaning the saws.

6. In a cotton-gin, the combination with the saws and brush-cylinder, of a plurality o l ribs having angular faces for contact with the brushes, and means for adjusting said ribs from and toward the brush-cylimler.

7. In acotton-gin, the combination with the saws and brush-cylinder, of a Avotally-mounted frame, a plurality of ribs carried thereby and extending between the saws, and means for adjusting the position of the frame and ribs to move the latter ribs into and out of operative relation with the brush-0y]inder.

8. In acotton-gin, the combination with the saws and brush-cylimler, of a head member formed of a pair of rigidly-united plates, one of said plates having longitudinal grooves in its opposite edges, a pivot-rod secured in one of the grooves, and a plurality of ribs secured in the other of such grooves and spaced apart for entrance between the saws, the head member being adjustable on its pivot-rod to alter the relative positions of the ribs with respect to the brush-cylinder.

In testimony that I claim the 'loregoing as my own I have hereto allixed my signature in the presence of two witnesses.

STEPHEN \V. IOYVER.
