ALEXANDER W. SKIINNER, OF PROVIDENCE, RHODE ISLAND.

Specification forming part of Letters Patent No. 135,015, dated January 21, 1873.

To all whom it may concern:

Be it known that I, ALEXANDER W. SKIN- NER, of Providence, in the county of Providence and'State of Rhode Island, have invented an Improved Condenser-Tube for Garding-Machines, of which the following is a specification: V

The nature of my invention consists in a cross bar or wire arranged centrally across the mouth of a contraction in the bore of the condenser-tube, or across the inner opening of a ring or tube of smaller caliber than the main tube, and at such a distance therefrom as will produce the required degree of friction upon the roping as it is being drawn through. It also consists in forming the lesser caliber in a separate tube or ring, so that the distance of the inner opening from the centrally-arranged cross bar or wire may be adjusted at pleasure, in order to increase or decrease the-friction on the roping, thus regulating its size.

Figure 1 represents the ordinary condensertube with its flier. Fig. 2 is a longitudinal sectional view of the same. Figs. 3 and 4 represent one form of my improved condensertnbe. Figs. 5 and 6 represent my improved adjustable condenser-tube.

in Figs. 1 and 2, a a are the bearings upon which the tube A revolves. B is the flier formed by the bent wire b, to which the crosswire I) is fastened; The roping (3 passes be tween the wires, as shown in Fig. 2. The flier B is unsatisfactory in its operation, from the lack of a sufficient guide beyond the bar b to preserve the concentricity of the roping, which, on this account, is liable to fly out from its proper line beyond the flier, thus causing a break in the web of which the roping' is to be formed. Also, in the adaptation of the flier B to the formation of roping of different sizes, it has been customary to increase 13116 diameter of the bar I) by winding it with thread and filling the interstices of the thread with wax, the whole having to be renewed every few days, at a considerable loss of time. The operation of the flier under such circumstances invariably produces an uneven roping,

which must result in an inferior quality of yarn, from its necessary lack of the proper uniformity. D, in Figs. 3 and 4, represents the smaller tube, before the mouth of which is placed the centrally-arranged cross-wire b. By means of the smaller opening D, placed beyond the wire I), the roping is kept in the proper line with the axis ot'the revolving tube, and is not, therefore, liable to the disastrous effects of the centrifugal force as imparted by the old flier above described. In cases where a uniform style of goods is to be manufactured, the device shown in Figs. 3 and 4 is sufficient; but where different sizes of yarn are to be made, the opening of the contracted tube D, or its equivalent ring, should be made adjustable in regard to its distance from the crossbar I). In order to effect this I preferably cut a thread upon the exterior surface of the tube D, which fits in a female screw cut in the tube A, the proper position being rigidly preserved by means of the check-nut E. Other modes of holding the tube D in position may be used; but the one shown is deemed the most practicable.

My improvement greatly facilitates threading the tube, since the roping-web may be caught by the hook used for the purpose and drawn direct-1y through the tube, whereas in the case of the old wire flier the web is first passed through the tube by means of the hook, and then passed through the flier by the fingers, the whole machine having to be stopped during the operation; whereas with the use of my improvement the tube can be threaded up without such stoppage.

" "1." The combination of the tube A with the cross-bar b and tube D, or its equivalent, arranged substantially as described.

2. The combination of the tube A, the adiustable tube D, or its equivalent, and crossbar 1), arranged substantially as described. ALEXAN W. SKINNER. Witnesses:
