MECHANISM FOR CARRYING WIRES THROUGH GONDUII'S.

SPECIFICATION forming part of Letters Patent No. 450,206, dated April 14, 1891.

Application filed September 24, 1890. Serial No. 365,949. (No model.)

To all whom it nmy concern: I I

Be it known that I, FERDINAND A. WEssEL, a resident of Brooklyn, Kings county, State of New York, have invented Improved Mechanism for Threading Vires and the Like Through Pipes, of which the following is a specification, reference being had to the accompanying drawings, forming part thereof, wherein Figure 1 is a top view, partly in section, of two conduits, one of which is shown in section, with my improved wire-carrying mechanism in position for action. Fig. l is a top view of my improved mechanism, showing it contained within a conduit, which is represented in section, the two carriages of my mechanism being apart. Fig. 2 is a similar view to Fig. 1, but representing the two carriages in contact. Fig.3is a side view of my improved mechanism with the carriages in contact, the mechanism being represented in a subway, which appears in section. Figs. 4 and 5 are enlarged horizontal sections on the line kk', Fig. 6, of the outermost or loose carriage, showing the clamps respectively drawnin and pushed out. Fig. 6 is a detail vertical section on the lines 0 0 Figs. 2 and 4, of the last-referred-to carriage. Fig. 7 is a detail vertical section on the plane of the line 0' c, Fig. 1, looking outwardly-that is, in the direction of the arrow placed near said sectionline 0 0', but showing the pins in the other end of the slots as they appear when the clamp is forced out. Fig. 8 is a detail crosssection through the wire-carrying mechanism and through the conduit embracing the same, the line k k Fig. 6, indicating the plane of section. Fig. 9 is an enlarged top view of the innermost end of the wire-carrying mechanism; and Fig. 10 is a detail vertical section of said end on the line 0 0 Fig. 9. Fig. 11 is a top view of a modification of my improved mechanism, showing it within a conduit, which is represented in section; and Fig. 12 is a side View of said modification, showingit likewise within a conduit represented in section.

The object of this invention is to provide means for drawing a wire, a cable, a rope, or analogous thread through a long tube or conduit from end .to end when such tube or conduit has no facility for placing such thread into it through any longitudinal opening in other words, a long. tube open only at its ends is by my mechanism to be threaded with a wire or cable or the like, so that for telegraphic, telephonic, and other electrical conductors ready means for placing them within conduits already in position shallbe provided.

To this end my invention mainly consists of two self-clamping carriages and a suitable mechanism to move them from and to one another, one of said carriages being shown secured to a carrier or stem, while the other is shown adapted to slide on saidv shank or stem, the combination operating in such a manner that while the outer carriage clamps itself tight within the conduit it is utilized as a bearing for drawing the stem and the remaining carriage inward, after which the inner carriage clamps itself tight in the conduit and allows the outer carriage to be drawn up toward it, and thus a wire or set of wires attached to the central stem or carrier can gradually, by a step-by-step motion, be moved into and ,through the entire length of the tube.

In order to give a clear description of this invention with reference to the drawings, (omitting for the present Figs. 11 and 12,) I will now proceed to describe said drawings.

In the same the letter A represents a suitable tube or conduit through which the wires 13 B (see Fig. 1) are to be drawn, or, inother words, the tube A is to be threaded with the wires B. These wires are secured by tying 01' otherwise to a stein or carrier 0, which is as long as necessary for the purpose of this mechanisniand straight fora straight tube, but may be correspondingly curved for a curved tube. Supposing the stem 0 to be inserted into the tube A so that one end enters the tube while the other slightly projects therefrom, as in Fig. 1, we will call the one end which enters the tube the innerand the other end, which projects therefrom, the outer end of the stem or shank. To the inner end is secured by a bolt a what I call the inner carriage D, and at a distance outward from this inner carriage D is fitted so as to be able to freely slide the outer or sliding carriage E. The

two carriages D and E are connected with being hung in the plates 6.

each other by strong springs F F, which have the tendency, normally, to draw the two carriages D E close together, asin Figs. 2 and 3, but which permit said carriages to be moved asunder, as in Fig. 1.

In the drawings the stem or shank C is represented as being composed of two long parallel bars I) b, which are rigidly connected together by a cross-pin (Z at or near their outer ends, but which otherwise leave a free longitudinal passage between them for the play of the carriages and their parts, as will hereinafter more fully appear.

I will now proceed to describe the construction of the outer or sliding carriage E. The said carriage consists, mainly, of a rigid frame which embraces the stem or shank O, and which is composed of two plates 6 e, that may have projecting ribs 6 6 as shown in Fig. 8. Each of said plates has the length of the carriage itself, the said plates being united into a rigid structure by vertical connecting-pieces g, there being also horizontal connectingpiecesf between the ribs 6 for furnishing an attachment to the end of the spring F. The frame 6 g of this carriage E thus constructed is free to slide on the stem or shank O, and in turn the stem or shank C is free to slide within said carriage E. Near the inner end of the carriage E is placed a sliding bolt h, which carries side lugs or a cross-piece 7L2, that connects by springs 'i with the inner end of the carriage E, as shown in Figs. 4 and 5.

G G are clamp-plates for clamping the car riageE to the tube A. These clamp-plates are pivotally connected at j to the laterally-slotted cross-piece 71 the pivot-pins j passing also into slanting or converging slots Z of the plates 6. The outer end of each clamp-plate has a pin m, that enters into a slanting slot 12, provided for its reception in the plate a. The edges of the two clamps G G, that face each other,are respectively parallel with the inclination of the slots Z n and are in contact with frictionrollers 0, which are carried by the carriage E, It will appear from a comparison of Figs. 4 and 5 that whenever the bolt his moved outwardthat is, to the right in Fig. 4:so as to strain the springs i the clamps G G will be made to approach one another, whereas whenever the bolt 71 is drawn inward by the springs 2', as in Fig. 5, it will draw the clamps with it, and will thereby bring them into the outer parts of the slots Z n, so as to expand said clamps. It follows that whenever the springs 11 are not strained theclamps are expanded sufficient to securely hold the carriage fast in the tube, but that whenever the springs t are extended the clamps are loosened, being drawn inward.

As far as I have now described the construction of the carriage E the foregoing description applies to the construction also of the inner carriage D, and I shall not, there fore, give any further attention to the description of the inner carriage, except to state that the inner carriage is securely attached to the stem or shank O by the pin or. bolt a, as in Figs. 9 and 10; but the outer carriage E has one additional element which is not found in the inner-to wit, a pulley or friction-roller 19, secured in its outer end, for receiving around it a rope H, by which the instrument is actuated.

Having now fully described the construc tion of my mechanism, I will proceed to describe its operation. A wire, cable, or thread to be passed through the tube A is attached, as in Fig. 1, to the outer end of the stem or shank Onamely, to the pin d, which for this purpose is formed on the said stem or shank; but of course any other means for permitting a convenient attachment of the wires may be provided on the said stem or shank. The rope H is now laid around the pulley p, and one end of said rope is then tied to the pin 01. The other end of the rope is free to be grasped by the operator and must be of a length at least equal to the length of thetube A. The instrument which I have described, and which is now ready for operation, is now inserted into the tube A through one open end of said tube, it being of course understood that the clamps G G on the carriages are so proportioned that when expanded they will securely hold their respective carriages in the tube. hen now the attendant pulls on the free end of the rope H, the first effect is to draw the carriage E slightly outward until the clamps G take atighthold onv the inner face of the tube A, the springs 11 of the carriage E being unstrained at this stage of the proceeding. A further pull on the rope will now propel the stem 0 forward, and withit the inner carriage D, which, as soon as the inward motion commences, strains its springs i, and thereby releases its hold on the tube. Hence as long as the operator pulls on the rope the carriage E remains stationary, and the stem or shank O, withthe carriage D, is moved or drawn inward into the tube, Thereuponthat is, as soon as the pin 61 has approached the pulley p as near as practicable the operator lets go of the rope H, and immediately upon so doing the clamps G of the inner earriage grip the inner side of the tube and hold fast, thereby enabling the springs F F to pull the outer carriage E inward, which said springs are enabled to do because the clamps G of the outer carriage relax their hold the moment the inward pull begins. In. other words, each of the carriages is arranged to automatically clamp itself in the tube when there is no strain upon it or when there is a strain or pull upon it in an outward direction and to automatically let go of this grip as soon as a pull in an inward direction is applied, and thus it is that while the attendant pulls on the rope H the carriage E is stationary and the carriage D is advanced by the direct pull of the operator, and that when the attendant lets go of the rope the carriage D remains stationary and the carriage E is advanced by the contraction of the springs F, and thus by a stepby-step motion the alternate pulling and relasing of the rope lI causes the entire inachinery which I have thus described to pass along in the tube A until finally it emanates from the farther open end thereof or reaches any other desired position therein. From this farther end the entire machine can be conveniently withdrawn from the tube, because, as I have already stated, both sets of clamps relax their hold as soon as their respective carriages are moved in the direction which I have termed the inward direction, which will be the discharge direction at the farther end of the tube.

The modification which is shown in Figs. 11 and 12 differs from the construction heretotore described only in the location of the pulley pand spring F. In this modification the pulley p is hung in the inner carriage D, and the two carriages D E are not connected together by the spring F; but instead the spring F connects the outer carriage E with the outer part of the stem or shank O, the result being that when the rope H is pulled the inner carriage D remains stationary, the outer carriage E is pulled inward, and thespring F strained, and when, afterward, the rope H is relaxed the outer carriage E clamps itself tight, allowing the spring F to pull the shank Y C, and with itthe inner carriage D, ahead, and
