Application filed May 2'2, 19%.
To alZ whom it may concern.
Be it known that We, ELwoon B. Areas and Cinmnics S. Momuson, citizens of the l'niled States, residing, respectively, in Melrose Park, Montgomery County, Pennsylvania, and Elkins Park, Montgomery County, Pennsylvania, have invented certain TH'XPIOYQXIIGHES in Toggles, of which the following is a specification.
Our invention relates to certain improvements in toggles used in stretching leather on drying frames during the process of manufacture.
The object of our invention is to improve the construction of the toggle so as to allow it to be used in stretching the leather and to hold it in the stretched position. This object is attained in the following manner, reference being had to the accompanying drawings, in which,
Fig. 1 is a perspective view of our improved "toggle;
Fig. 2 is a side View showing the toggle in the open position;
Fig. 3 1s a sectional View showing the toggle in the closed or gripping position;
Fig. 4 is a sectional View on the T 1g. 2; I Fig. 5 tric aw;
Fig. 6
line H,
is a perspective view of the eccenis a perspective view of the hand lever for closing the toggle; and
Fig. 7 is a View illustrating a modification of the invention.
The body 1 of the toggle is made of spring metal and is bent, in the present instance, as clearly shown in the drawings, so as to form a back plate 2, and a clamping plate 3. Punched from the back plate is a hook 4, which is arranged to engage a supporting frame 5 that may have a body in the form of a wire screen, or perforated metal. A looped portion 6 of the toggle not only forms a spring member, but also is shaped to provide a finger hold by which the operator can engage the toggle and can stretch the leather to the desired extent. The leather is shown as a, in Fig. 3.
Two bearings 7 are formed on the back plate for the trunnions 8 of an eccentric jaw 9, having teeth 10 which are shaped, preferably as shown in Figs. 2 and 5. This jaw has a tongue 11, which extends between the two members of a U-shaped bearing 12 Serial Ito. $16,134.
that extends through slots in the back plate 2, and through slots in the clamping plate 3. Pivoted at 13 to the til-shaped bearing 12 is a hand lever 14. On the short arm of this lever is a pin 15, on which is mounted a roller 16. This roller bears upon the clamping plate 3 and forces the clamping plate towards the jaw 9, when the lever lfl is moved from the position shown in Fig. 2 to that shown in Fig. 3. When the edge of the leather is inserted in the space between the clamping shown in Fig. 3, its pivot, it will and the lever is turned on clamp the leather onto the jaw. i l hen the hook 4 is in position to engage the frame 5, any pull upon the toggle by the operator will tend to turn the eccentric jaw 9 on its pivot, thereby increasing its grip upon the leather.
The lever 14, in the present instance, has a flange 17, which forms a stop, as shown in Figs. 3 and 6, that prevents the lever 14 passing beyond the position illustrated in Fig. 2. The lever comes in contact with the portion 6 of the toggle, and limits its movement in the opposite direction. When the lever is in the position illustrated inFig. 3, th roller 16 is on one side of the pivot and locks the clamping plate 3 in position. In Fig. 7 is illustrated a modification of the invention, in which a clamping plate 3 is independent of a body 1 of the toggle and is shaped, as shown, to form a rounded bearing '3" for a cam 14*, having a handle 14:". The end of the clamping plate extends through a back plate 2 and forms a hook 4. The cam 14c is mounted on a bolt 18 and on the bolt is a spring 19, which tends to force the clamping plate 3 away from an eccentric jaw 9 that is preferably made in the same manner as the jaw 9, with the exception of the tongue 11, which may be omitted. llt will be seen that a toggle made in accordance with our invention positively engages the leather, and retains its grip on the leather as the leather is stretched onto the frame.
The greater the pull, the tighter the leather is gripped by the eccentric jaw.
lit will be understood that in stretching leather on a frame during the process of manufacture, there are a number of these toggles located around the leather, so that it can be stretched to the desired extent,
and the toggles secured to the frame, the leather being held firmly duringthe drying operation. {a
We claim:
1. The combination in a toggle, of a body portion having aback plate and a clamp plate integrally connected by a spring section; aneccentric jaw" pivotally mounted on one of said plates; and means for forcibly moving the clamp plate towards the back plate.
2. The combination in a toggle, of a body portion having a back plate and a clamp plate; an eccentric jaw pivotally mounted eaf/nee on the back plate; and means for forcing the clamp plate towards the jaw.
3. The combination in a toggle, of a body portion shaped to form a back plate, a clamp plate and a spring connecting member tending to open the toggle; a bearing secured to the back plate and extending through the clamp plate; an operating lever pivotally mounted in the bearing; and a roller carried by the lever, said roller having a rolling contact With the clamp plate as the lever is turned on its pivot.
