SPECIFICATION forming part of Letters Patent No. 629,871, dated August 1, 1899.
- I Application filed March 31, 1880. Serial l lo, 6,396. (N 0 model.)
To ctZZ whom it may concern.-
Be it known that 1, CHARLES A. POSTLEY, a citizen of the United States, and a resident of Austin, in the county of Travis and State of Texas, have invented certain new and use.- ful Improvements in Cord-Tying Devices; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being hadto the accompanying drawings, and'to letters of reference marked thereon, which form a part of this specification.
My invention relates to improvements in mechanical devices constructed for the purpose of tying automaticallya knot in a cord, whichare commonly known as knot-tiers and used ordinarily tounite the ends of a band encircling abundle of grain.
My invention consists of a cylinder having stops or shoulders at its end, in combination with a notched and bevel-faced lug attached to the said cylinder near its said end anda Vibrating hook, by means of which and the said lug the cord is gripped firmly and held during the formation of the loop anduntil the knot has been formed and drawn close.
It further consists of a vibrating rod united with certain parts so arranged, constructed, and operated that the end of the cord forming the loop'is grasped, the said loop formed on the cylinder forced from off it, and the end of the cord which has been grasped drawn through the loop and within the cylinder, thus making a tight knot.
It further consists of certain other parts and combinations, which will be more fully hereinafter explained, and pointed out specifically in the claims. 7
The object of my invention is to supply a means for formingin acord a knot which shall be made tight before the cord is released from the tier andwhich willrequire no subsequent employment of other instrumentality to take up slack for the purpose of making the knot firm and secure.
In the accompanying drawings, forming a part of this specification, Figure 1 is a perspective View of a tier constituting my invenaway and the parts represented in the positions they occupy when at rest. Fig. 2 is a portion of the forward part of the tier. shown in longitudinal section. Fig. 3 is a perspective view of certain detailed parts of the same. Fig. 4 represents a portion of the cylinder of the tier in longitudinal section with the clamping-jaws by which the end of the cord is drawn through the loop advanced to a position ready to grasp the said end of the cord. Fig. 5 shows a portion of the forward end of the tier, the end of the cord having been grasped by the clam ping-jaws and the loop which was formed around the shouldered end of the cylinder being shoved therefrom. Fig. 6 is an enlarged end view of the tier, showing the cord partially wound around the end of the cylinder. Fig. 7 is. another enlarged end view of the same, showing the cord wound around the end of the cylinder, the loop formed, the ends of the cord being against the stops or shoulders and across the mouth of the cylinder and the clampiug-jaws advanced to aposition similar to that represented at Fig i read y to grasp it. Fig. 8 is a similar view of the tier, the cylinder being in a positionlike that represented in Fig. 5, but the clamping-jaws having receded the knot in the cord is about being drawn tight. Fig. 9 shows a longitudinal section of the cylinder forming a part of my invention, witha side elevation of a modification of the clamping-jaws represented in preceding figures. Fig. 10 is areverse side View of the said modification of the clampingjaws. Fig. 11 represents a modification of the means employedto retain the cord on theface of the cylinder at its shouldered end, the forward portion only of which is shown. Fig. 12 is a perspective view of the device for drawing the cord through the loop, having its springjaw shown in its abnormal or open position. Similar letters, Where they occur in all the figures, indicate like parts.
The letter a indicates a metallic cylinder which may be of any required length or diameter found best suited for the purpose for which it is designed. On theperiphery of this cylinder at, near its end, is a bevel-faced lug d, having a projecting lip 02, that extends tion, a portion of the cylinder being broken 1 nearly to the end of the cylinder, as shown in Fig. 2. Encircling the cylinder Ct back of the lug d is a sliding collarb, which has attached to it a rod 0, working through slot '5 in the cylinder at. This rod 0, which extends forward, as shown in Fig. 2, is sustained in place by a guide It within the cylinder a and has at its extremity a hook e, which when drawn back by the collar b enters a notch 6, cut in the end of the cylinder a im med iately beneath the projecting lip d of the lug d. The hook e and the beveled lug d,with its projecting lip d, constitute the looping hook or jaw of my tier, by means of which the cord is grasped and held while the loop is being formed and the knot made.
The cylinder or tube Ct has at its forward end and on opposite sides two stops or shoulders f f, which may be formed, as indicated, by cutting away at fa portion of the cylinder to such a depth and extent as will best suit the requirements for which it is designed. Near the notch e in front of the lug d at the end of the cylinder at is a projection g, projecting laterally from the periphery of cylinder a and tapering from its base to a rounded point. (See Fig. 6.)
Working freely within the tube CL through a head 25 at its rear end. is a rod in, on which near its forward end is a collar 8, serving as a support and guide for it within the cylinder 0-. The forward part of rod is made slightly tapering, and to it, adjacent to and in front of the collars, is attached by rivets or otherwise a spring-finger m, as shown in Fig. 12. On the end of the spring-finger an overlapping the rod 70 is a short flange 01, and a little in the rear of it on the other side of the finger mis another flange n, Fig. 12; Standing outward from the edge of spring-finger m is a lug p, located-in the rear of the flange 11, Figs. 7 and 12. Within the cylinder a, near its forward end, is secured a spring-cam q, which is so attached to the cylinder that its rear end is left to vibrate freely, Fig. 4. The spring-finger m, together with the rod 70, form a clamp, by means of which the end of the cord is seized and drawn through the loop and within the cylinder a, and the knot made tight after the loop around the projecting end of the cylinder has been shoved therefrom by the lug Z on the forward part of rod k. (See Figs. 5 and 7.) The spring-cam q is set at an angle, the rear end being below the line of the edge of the finger m, while its forward end, which is fast to the inside wall of the cylinder, is arranged at a suitable distance above it. lVithin-the cylinder at in line with the spring-cam q is a short cam q, inclined in a reverse direction from the spring-cam q, as shown in Fig 4. The object attained by the use of the cam q and the spring-cam q will be best understood from a description of the operation of thetier.
To allow the collar 5 on rod'k to pass the cam q when the rod 7c is moved forward and back, a notch is cut in its periphery, as shown in Fig. 12.
To tie a knot in a cord by my invention, the operative parts may be worked by any mechanical means best suited for the purpose. The two strands of the cord having been brought to a position to be caught between the hook e on rod 0 and the projecting lip of the lug d, the collar 1) is moved back, thus drawing the cord against the lug d and confining it between the projecting lip d, the hook e, and the periphery of the cylinder a and firmly holdingit. When the parts would occupy the position shown in Fig. 2, the rod 70 need not be at this time advanced. The cylinder at is then revolved in the direction indicated bythe arrows in Figs. 6, 7, and 8 and the cord is wound around and upon the forward part of the tube a until it reaches the cut-away portion f, when it crosses the open end of the cylinder in the manner shown in Fig. 6, resting upon shoulders f, and is again wound around and upon the projecting end until forced to run over the end and again cross the open end, as before, by the beveled lug cl. The loop thus formed is prevented from slipping off the end of the cylinder by the projection g and the part of the cord confined by the finger e and the lip d. The rod his now advanced, and the lug pon the finger m coming in contact with the free end-of the flexible or spring-cam q rides upon it, thereby raising the fingerm from off the rod It, as shown in Figs. 4 and 7. At nearly the same time as the cord recrosses the open end of cylinder Ct, as shown in Fig. 7,'the clamping-jaws reach a position similar to that represented in Fig. 4, when the rod 70, still continuing to move forward thelugp on finger m, slips from the cam q and the cord is grasped between the spring-finger 'm and rod 70, the flange n being beyond the cord, as shown in Fig. 5, While the flange a, pressing it sharply down on the side of the rod 70, renders the hold of the jaws more secure. The cord leading from the spool to where it is held by the hook e and lug d is now severed within a short distance of the tier; The rod 70 having continued to advance, the lug Z comes in contact with the cord stretched across the open end of the cylinder from the opposite shoulders f and forces the loop off the end of the cylinder, as shown in Fig. 5. It is obvious that on the rod lubeing retracted theend of the cord held by the jaws of the rod will be pulled through the loop, as in Fig. 8, and the knot drawn tight around the end of hook e; but the instant that the knot is thus made tight around it the collar Z2 is moved forward, and the knot consequently slips from the point of hook e and is drawn completely close and tight by the receding clamping-jaws. As the knot is thus drawn hard and tight, the rod 7c in receding brings the lugp in contact with the inclined cam g causing the spring-fingerm to be again raised-from the rod 75, thus releasing the end of the cord from the clamping-jaws, within which it has been firmly held for reasons already stated until the knot was made secure.
pivoted at r to the rod 71;, as shown in Fig.
10, constituting with it what are commonly known as tweezers, the jaws of which are held closed by a spring. In using these tweezers a standard 0 is arranged on the cylinder a, which has hinged to it the hanger o, as at Fig. 9, working through a slot as in the cylinder and held in position by a spring a. \Vhen the rod is advanced, as already described, the tail a of the lever pivoted near its end will be depressed by the hanger o, as in Fig. 9, thus causing the jaws of the tweezers to .open and be so held until the end of the tail ready described, and the rod is receding, the pivoted hanger 0 gives way to the pressure of the end of the tail of part to, allowing it to pass, but is restored to position by the spring 42'). The rod 70 continuing to recede for the purpose before described, the tail it comes in contact with a short inclined cam (0 Fig. 9, by which it is again depressed and the jaws of the tweezers opened, thus freeing the cord.
Instead of employing the hook e and lug d for grasping and holding the cord, as described, a lever pivoted at o in a standard n on the cylinder ct, as in Fig. 11, having the long forwardly-projecting hooked end at and short upwardly-curved tail d may be used. The hooked end will be raised from the face of cylinder (1, as represented by the broken lines, or held firmly thereon by means of the collar Z), having the standard b,through a properly-formed slot in which the short tail (1 works when the said collar is moved back or pressed forward.
It is apparent that the above -described modifications may be used either separately with the other parts of the tier orin combination with each other and an equally satisfactory result be obtained in tying a knot in a cord.
Should it be found desirable, it is obvious that lugs 19 may be formed on each side of spring-fingermand correspondingly-arranged cams q and g be placed within the cylinder 0..
