Description

March 15, 1955 L. E. AMSPACKER 2,704,061
RING SPREADING DEVICE Filed Oct. 27, 1953 ATTORNEYS United States Patent 1 2,704,061 RING SPREADING DEVICE Lloyd E. Amspacker, Glasco, Kans. Application October 27, 1953, Serial No. 388,530 4 Claims. (Cl. 128303) This invention relates to a ring spreading tool.
It is a principal object of this invention to provide a ring spreading tool for spreading apart a resilient ring or the like when it is desired to engage the resilient ring about an article, the ring to be inherently contracted about the article when it is removed from the tool.
It is another object of this invention to provide an Improved ring spreading device of this kind to spread a rubber docking, dehorning or castrating ring.
It is a further object of this invention to provide an mproved ring spreading tool of this kind having three aws for engaging the resilient ring to be spread open thereby facilitating the spreading apart of the ring to be later removed from the jaws for applying the spread apart and open ring to an article removed from the tool.
It is still another object of this invention to provide an improved resilient ring spreading tool of the kind to be more particularly described hereinafter which is easy to operate when and as desired and which may be constructed at an economical cost to the user.
Other and further objects and advantages of the invention will be hereinafter described and the novel features thereof defined in the appended claims.
In the drawings:
Fig. 1 is a side elevation of an improved ring spreading device constructed according to an embodiment of my invention.
Fig. 2 is a rear elevation.
Fig. 3 is a top plan view of the device engaging a resilient ring in its contracted position.
Fig. 4 is an enlarged horizontal section, partly broken away, taken on the line 4-4 of Fig. 2.
Fig. 5 is a top plan view, partly broken away, of the device engaging the resilient ring in the extended position of the ring.
Referring more specifically to the drawings, the numeral designates generally a ring spreading device, constructed according to an embodiment of my invention wherein the inherently resilient ring is adapted for docking, dehorning, or castrating. The resilient ring is adapted to be spread apart by the ring spreading device 10 and placed in position and removed from the jaws of the ring spreading device 10 much in the manner of removing the spread apart resilient ring with a pair of pliers.
The resilient ring spreading device 10 is provided with a rigid semi-circular base ring 11 having a jaw finger or jaw member extending radially outwardly from one end of the semi-circular base ring 11. The jaw member or finger 12 is formed integral with an end of the base ring 11 and is flattened throughout the length thereof so that a resilient ring may be slidably placed on the jaw finger 12 or removed therefrom.
A pair of diverging outwardly extending arms 13 are secured to the other end of the base ring 11 and extend outwardly therefrom in a direction perpendicular to the radius of the base ring. The outwardly extending arms 13 and 14, being positioned in divergent relation to each other are provided with an opening adjacent to the end thereof, removed from the base ring through which a pivot pin 15 is adapted to be slidably engaged for mounting a pair of levers 16 on the base ring. The pivot pin 15 will engage the lever 16, intermediate the length thereof so that the lever may be pivoted about the pivot pin 15.
A semi-circular jaw ring 17 is formed on one end of each of the levers 16 and each of the semi-circular jaw rings 17 is provided with a radially outwardly extending jaw finger 18 for slidable engagement within a resilient ring R which is also engaged by the jaw finger 12 on the base ring 11.
A handle 19 is secured on the other end of the lever 16, remote from the semi-circular jaw rings 17 whereby upon moving the handles 19 together, the jaw fingers 18 will be moved apart relative to each other and to the jaw finger 12 on the base ring for opening the resilient ring R.
In the use and operation of the ring spreading device 10, the handles 19 are initially pivoted on the arms 14 for moving the jaw fingers 18 and jaw finger 12 together for sliding engagement of the jaw fingers within the loop formed by the resilient ring R in its contracted position. Upon moving the handles 19 together the jaw fingers 18 will be moved outwardly relative to each other and relative to the jaw finger 12 on the base ring 11 for expanding the resilient ring R whereupon the resilient ring R may he slid outwardly from engagement with the jaw fingers onto the device on which the resilient ring is to be positioned and after removal of the resilient ring R from the ring spreading tool 10, the resilient ring will be inherently contracted to its closed position and the tool 10 may be freely removed from the article and from the resilient ring.
While the specific details of one embodiment of this invention have been herein shown and described, the invention is not confined thereto as changes and alterations may be made without departing from the spirit and scope thereof as defined in the appended claims.

A novel resilient ring opening tool of this kind comprising a semi-circular base member, a pair of divergent arms on one end of said base member, an outwardly extending jaw finger on said base member for removably engaging within a resilient ring to be opened, a semicircular jaw member pivoted on each of said arms, an outwardly extending jaw finger on one end of said jaw members detachably engageable within the ring to be opened, and a handle on the other end of each of said jaw members for pivotally opening said fingers thereby ggening the resilient ring detachably engaged on said jaw gers.
2. A novel resilient ring engaging device of the kind described comprising a semi-circular base member, a radially outwardly extending jaw member at one end of said base member for engaging within a ring to be opened, divergent outwardly extending arms on the other end of said base member, a semi-circular jaw ring member pivoted on each of said arms, a radially outwardly extending jaw member one end of each of said jaw ring members for engagement within a resilient loop to be opened, and a handle on the other end of each of said jaw ring members.
3. A novel resilient ring opening device of the kind described comprising a rigid semi-circular base ring, a radially outwardly extending jaw member on one end of said base ring, diverging outwardly extending arms on the other end of said base ring, a semi-circular jaw ring pivoted at one end thereof on the other end of each of said arms, a radially outwardly extending jaw on the other end of each of said semi-circular jaw rings for cooperation with said jaw member on said base ring for sliding engagement within the resilient ring to be opened, and a handle on each of said semi-circular jaw rings extending outwardly from the pivot thereof in a direction opposite from said jaws.
4. A novel resilient ring opening device of the kind described comprising a semi-circular rigid base ring, a fiat jaw finger on one end of said base ring, outwardly extending diverging arms connected at one end thereof to the other end of said base ring perpendicular to the radius of said base ring, a lever pivoted, intermediate the length thereof on the other end of each of said arms, a semi-circular jaw ring on one end of each of said levers, a fiat jaw finger on one end of each of said jaw rings, a pivot pin through each of said levers intermediate the length thereof and the other end of one of said arms, a handle on the end of each of said levers remote from the jaw finger of the respective jaw rings for opening a resilient ring removably engaged on said jaw fingers.
