Specification of Letters Patent.
Patented Aug. 15, 1905.
Application filed October 27, 1904. Serial No. 230,265-
To all whom, it may concern:
Be it known that 1, CHARLES A. HARTMANN, a citizen of the United States, residing at Hoquiam, in the county of Chehalis and State of Washington, have invented certain new and useful Improvements in Machines for Tightening Bale-Ties, &c.; 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.
My invention relates to a device for tightening and tying wire bale-ties, which have a loop in one end, around bundles, box-shooks, or wherever bale-ties are used, the object being to force the loop down along the free end of the bale-tie until the required tension is produced and then complete the tie by bending the free end around the loop.
My invention consists in certain novel features of construction and the equivalents thereof shown in the accompanying drawings and set forth in this specification.
Figures 1, 2, and3 are side elevation, plan view, and end elevation, respectively, of the machine attached to a wire bale-tie and ready for operation. Fig. 4 is a plan View of part of the machine, showing the manner of bending the free end around the loop after the bale has been drawn taut and also the manner of releasing the tie from the machine. Figs. 5, 6, and 7 are elevations showing the general construction of the upper pawl for operating the forcing-bar; and Figs. 8, 9, and 10 are elevations of the lower pawl. Figs. 11 and 12 are side elevation and plan view of the forcing-bar. I
A is a notched bar, which I term the forcing-bar, With a projection B, which enters the loop of the bale-tie. The projection B has a groove B along its side.
0 is the loop end of bale-tie.
D and E are parts of a clamping device which grips the free end of the bale-tie While the machine is pulling the tie taut.
F is a lever which operates the machine.
G and H are two pawls which engage alternately in the teeth of the forcing-bar A as the lever F is moved back and forth.
M is a spring which normally keeps the pawls in engagement with the forcing-bar A.
The operation of the machine is as follows, it being borne in mind that the object is to force the loop 0 down along the free end of the baletie after the bale-tie is in position around the bundle and to complete the tie by bendingits free end over the looped end when the wire has been broughtto full strain: The projection B' of the forcing-bar A is inserted in the loop C of the bale-tie. The free end of the bale-tie is threaded through the loop (J, passed along the groove B in the side of the projection B and between the grips of the clamping device D E. This clamp isjadapted to automatically grip the free end of the wire while the wire is being drawn taut by the forcing-bar. The lever F is moved backward and forward, and acting alternately through the pawls G and H moves the forcing-bar A in the direction of the arrows in Figs. 1 and 2 and pushes the loop C down along the bale-tie. When the bale-tie is brought to its full strain, the machine is turned about the point B, as shown bydotted lines in Fig. 4:, so that the end of the wire will form an angle about the loop and prevent slipping. As the instrument turns the projection B is released from the loop, and at the same time the tension being relieved the wire is automatically released by the clamp.
As above stated, the clamping device D E grips the wire automatically. The device comprises a block or die D, carried by bracket D, having a slot D to receive the bar A. The free end of the bale-tie rests on the block D. E is a dog pivotally mounted on the bracket D. To its upper end is pivoted one end of the connecting-link E. The other end of the link is pivoted to the lever F. Movement of the lever F either backward or forward tends to tighten the dog E down on the bale-tie, for when the lever F is moved toward the left it acts pivotally about the stationary pawl G as a fulcrum, with the result that the link E is drawn toward the right and the dog E is tightened on the bale-tie, while at the same time the pawl H is moved toward the right and when the motion of the lever ceases it engages with the rack on the top of the bar A. vIn a similar-manner when the lever is moved toward the right it acts pivotally about the pawl H as a fulcrum and draws the link E toward the right as before, tightening the dog E on the bale-tie. The pawl Gris drawn toward the right'on the next stroke of the lever F toward the left, and the pawl engages with the next succeeding tooth. Teeth are cut in the lower edge of the dog to increase the grip of the clamp. All the strain produced in the bale-tie is transmitted through the clamping device. Consequently the greater the strain the more securely will the wire be held by the clamp.
The forcing-bar is of any suitable size, and is preferably rectangular in cross-section. It has teeth formed on its upper edge in which the pawls G and H engage, as shown. The groove in the side of the projection B gives clearance for the wire and prevents undue friction between the two parts of the bale-tie and reduces the tendency of the metal in the tie to heat and crystallize. The spring M keeps the tooth of the pawl Grin engagement with the teeth on the forcing-bar A. It also tends to raise the lever F, which forces down the tooth of the pawl H by acting about the fulcrum H on its upper side. The pawls G and H are of the general shape shown in Figs. 5 to 10. They have lips G and H at the side of the forcing-bar A to keep the lever F in position.
Although I have described my invention as shown in the drawings, various changes in construction might be made without departing from the spirit of the invention, and ldo not, therefore, wish to confine myself strictly to the details herein described.
What I claim as my invention, and desire to secure by Letters Patent, is as follows:
1. In a wire-tightening machine the combination of a toothed forcing-bar; a projection extending from one end of said bar having a groove along its side; a clamping device forcing-bar longitudinally; and a link pivoted to said lever and adapted to actuate said clamping device.
2. In a wire-tightening machine the combinationof a toothed forcing-bar; a projection extending from one end of said bar having a groove along its side; a clamping device adapted to grip the wire; a link pivotally connected to said clamping device; a lever pivotally connected to said link; a pawl pivotally mounted on said lever above said forcing-bar and having at one end a downwardly-projecting tooth adapted to engage the teeth of said forcing-bar; a projecting lip on said pawl at the side of said forcing-bar; a pawl pivotally mounted on said lever below said forcing-bar; the end of said pawl being adapted to engage the teeth of said forcing-bar; together with a projecting lip on said pawl at the side of the forcing-bar.
3. In a wire-tightening machine the combination of a toothed forcing-bar; a projection extending from one end of said bar; a clamping device adapted to grip the wire; a lever; and pawlscarred thereby and adapted to move said forcing-bar longitudinally; and a link pivoted to said lever and adapted to actuate said clamping device.
In testimony whereof I affix my signature in presence of two witnesses.
CHARLES A. HARTMANN.
