'-0rigina1 application filed septemberajwlb, Serial No. 48, 634., Divided and thislapplication filed February 10, "1916. Serial no. 77,450.

. To all whom it may concern:

Be it known that I, SETH B.-HaNsi1Aw, a citizen of the United States, and a resident of Charleston, in the county of Kamwha and State of West Virginia, have in vented a certain new and "useful Improve- 'ment' in Take-Down .Devices, of which 'the following is a specification.

My present invention relates generally to window glassmachine'ry of the general nature described and shown in my co-pending application Number 48634, filed September 2, 1915, of which the present application is a division. h

' 'More particularly speaking, my present invention relates to mechanism utilized in connection with window glass machinery, to take down the drawn glass cylinders preparatory to capping the same into lengths, which lengths are thereafter flattened out into the finishedsections of window glass.

The object of my present invention is to provide a take-down device, simple and effective in itself, and capable of simple and .efl'ective control with the use of but a smgle winding drum and main cable to be wound thereo y In the accompanying drawings illustrating my invention: Figure 1 is a vertical transverse section through a glass furnace" in connection with which my improvements are utilized. Fig. 2 is a similar view of a art of one side only, on an enlarged scale. Fig. 3 is a'detail plan view of the main drum and its driving means. Fig. 4 is a detail perspective-view of the controlling connections for the clutch of the main drum shown in Fig. 3. Fig. 5 is a detail end view of the take-down drum, and Fig. 6 is a detail of the clamp connection of the take-down cables.

' In Figs. land 2- in particular, are shown Each bait cage D just above mentioned is, in operation of the machinery, drawn vertically by a cable D, from the main.

winding drum D driven from a motor D and under control of a clutch D which is in turn-under control of a handjlever D in the operators box F, through certain leverage connections D as seen in Figs.'3

and 4. When the clutch D is thrown in,

the drum D is gradually rotated to wind the drawing cable D "thereon, gradually drawing the cylinder which, after being cut oil, is free to descend,carriage D then moving downwardly in guide C, when the clutch D is withdrawn. I v v For taking down the cylinder when drawn, and after being cut ofi at, its bait from the moltenmas's of glass, use is made, in accordance with my present improvements, of a n1aih--take-down cable N, passing over rollersv N", one end of this cable being securedto, the superstructure B as plainly seen in Figs. 1 and 2, and the other end leading to andaround a take-down drum L. This cable N supports a trolley N carryin'g'a hoop N capable of encircling the lower cut-off end; of a drawn cylinder when the latter is moved outwardly with the outward movement of the lower portion of the respective guide C, as shown at the left of Fig. l. y

To the above mentioned main take-down cable N is attached one end of a counter.-

weighted controlling cable 0, the connection being made by a clamp P above the level of the floor M and which clamp reaches the floor and limits further movement when the cable is wound on take-down drum 'L to a point suiiioiently to properly elevate the lower end of the drawn cylinder; During the drawing of a cylinder, however, cable N with its trolley N is on the floor with the weight 0 at the outer end of controllingcable 0 in lowermost position. Attachedalso at one. end to the above mentioned main take-down cable N, by the clamp P, is a baitcatching cable Q, the opposite end ofwhich carries a. hook Q engageable with a loop E of the bait E as shown in Fig. 2: Intermedi ate its ends, this cable Q p sses over spaced rollers Q and is provided between these rollers with a counterweight QE- by whichthe slack may be taken up during the drawing of the cylinder, .as the bait E and itsv cage D before mentioned, move upwardly in the guides C. But when a cylinder is-fully.

of cable 0, clamp 1 being in its raised position. VVhen the lower end of the cylinder is cut off and the hoop. N disposed therearound, the control operator in the box F pulls down upon the lever I which, through a flexible connection I',-actuates a belt tightener I operating against a normally loose belt L forming one of the intermediate power transmitting elements. between the take-down drum L and the motor G of the take-down apparatus. Upon such act,therefore, rotation is imparted to the take-down drum to wind the take-down. cable thereon, in the course of which the clamp P is drawn down to the floor M, raising the cable N and its hoop N and swinging the lower end of the drawn cylinder outwardly and upwardly.

The take-down drum, L is normally engaged and held inimmovable relation upon its shaft L as seen in Fig. 5, by means of a flexible band brake L connected at its ends 'to a lever L upon opposite sides of the pivot L of the latter, this lever being in turn acted upon by a spring L normallymaintaining the brake band in close contact with the drum. To the lever L is attached one end of a flexible connection J leading to a foot lever J in the operators box F which must .be depressed before the belt tightener I is actuated as before described to transmit rotation to the drum. During the move ments of the take'down drum to wind its cable thereon, the slack only of cable Q; is taken up, its weight Q being drawn up-' wardly to the rollers Q. The lever I is then released and foot lever J upon being depressed, releases the brake L from the take-down drum and thus permits the bait and its cage to lower, as soon as the clutch reaches its lowermost position, the foot lever J is released and brake L automatically engaging the take-down drum, checks further movement of the cable. Bait E being removably seated on the cage D as usual, is,

due to the foregoing, withdrawn entirely from the cage, and the finished cylinder swings freely out over the usual capping horse Itas clearly seen at the right in Fig. 1. It may then be gradually lowered onto the capping horse by again depressing foot lever J to allow of its further downward movement, after which brake L is again released, and weight 0 assists in unwinding the remaining part of the take-down means cable fromdrum L, so thatwhen detached w from the cylinder, the-trolley N may rest upon the floor between operations. I am thus enabled to effectively take down and control the drawn glass cylinder without a multiplicity of cables and winding drums, and by, in fact, using but a single drum and a single cable on the drum.

I claim 1- 1. In window glass machinery, a cylinder drawing mechanism including a bait and its cage, and a take-down mechanism, the latter including a take-down cable anchored at one end and having a trolley provided. with cylinder engaging means, a drunron which the opposite end of said cable is wound, driving means .for said drum, means for engaging said drum with, and disengaging the same from, said driving means, and a counterweighted cable and a bait engaging cable attached to said take-down. cable intermediate its ends, said bait engaging cable being attachz ble at its opposite end to the bait.

2. A take-down apparatus including a freely revoluble take-down drum, driving means therefor, manually controlled connections between the said drum and the said driving means',a manually controlled brake engageable with the said drum, a main takedown cable anchored at one end and having its opposite end attached to the drum, a trolley movable on the said cable and provided with cylinder engaging means, a bait engaging cablehaving a hook at one end and attached at its opposite end to the said take down drum at apoint intermediate the ends of the latter, a pair of pulleys over which the said bait engaging cable is intermediately extended, a weight secured to the said bait engaging'cable at a point between said pulleys, a controlling cable attached at one end to the take-down cable at a point interat its opposite end with a controlling weight, and guides over which the said controlling cable is intermediately extended.

3. A take-down apparatus including a manually controlled take-down drum, a takedown cable anchored at one end and having its opposite end attached to the drum, a cylinder engaging trolley carried by the takedown drum, a bait engaging cable having a bait engaging hook at one end and attached. at its opposite end to the said take-down cableat a point intermediate the ends of the latter. a pair of pulleys over which the bait engaging cable is intermediately extended, and a weight attached to the said bait engaging cable at a point between the said puleys.
