Specification of Letters Patent.
Patented Dec. 23, 1913.
Application filed May 23, 1913. Serial No. 769,536.
To all whom it may concern Be it known that I, Gnonon E. O'r'r, a citizen of the United States, residing at Lancaster, in the county of Erie and State of New York, have invented a new and useful Can-Top Set, of which the following is a specification.
The present invention appertains to can top implements, and relates more particu larly to certain improvements over the device disclosed in my former application filed Dec. c, 1912, Serial No. 755,340.
It is the object of the present invention to provide an implement of the nature indicated embodying novel means for setting or truing the flanges of can top rings.
With the foregoing and other objects in view, which will be apparent as the descrip tion proceeds, the present invention resides in the con'lbination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made within the scope of what is claimed without departing from the Spirit 011? the invention.
The invention has been illustrated in its preferred embodiment in the accompanying drawing, wherein Figure 1 is a plan view of the improved device, a portion being broken away. Fig. 2 is a sectional view of the clamping ring or female die, taken on the line 2-9 of Fig. 1. Fig. 3 is a sectional detail taken on the line 3-3 of Fig. 1. Fig. 4 is an enlarged sectional detail taken on the line -1ll of Fig. 1. Fig. 5 is a perspective view of the spring for opening the levers. Fig. (5 is a sectional view of a can top ring illustrating the improved implement applied thereto for truing the flange, the implement being shown in iragmental section. Fig. 7 is a sectional detail taken on the line 77 of Fig. 4t.
' The'crossed and pivoted levers l and 2 have the ends of the clamping ring or tomale die 3 pivoted to their outer ends or short arms, the clamping ring 3 being fully disclosed in the above mentioned application, and forming the subject matter thereof, so that the same need not be illustrated or described in detail herein. The thread, however, of the clamping ring or female die 3 is tapered at one side in order that the can top may be set without the employment of a male die, as described in the said application. The thread of the clamping ring being tapered at one side will permit the can top or can top ring to be gradually threaded into or through the clamping ring, as the clampin ring is repeatedly operated, whereby the tiread of the can top or can top ring may be set without the liability of it kinking. The pivotal portions of the levers l and 2 are enlarged or formed into cheeks t and 5, respectively, which lit snugly together. The enlargements or checks t and 5 are pivoted together by means of a rivet or pivot pin 6. In order to spring press the levers to separated or open position, the checks at and 5 have been provided with the complementary annular grooves 7 in which is housed a coiled wire spring 8. The spring 8 is preferably of about one and three-quarters turns, or slightly less than two turns or convolutions, and has its ends or terminals bent angularly in opposite directions to engage within the respective cheeks t and 5. The spring 8 has a normal expansive tension in order to yieldingly separate or open the levers, whereby after the lovers have been forced together by the hand, the spring will facilitate the separation of the lovers for a new operation. In order to limit the separation of the levers, the check 5 has been provided with a lug or stop 9 projecting from its inner face adjoining the periphery of the cheek -il, and the check 4 has been provided with the shoulder 10 complementing the stop 9 and adapted to strike the stop when the levers have opened to a predetermined extent. In this manner, the separation or opening of the lovers is limited to the desired extent,
The lovers are provided with novel means For setting or truing the flanges of can top rings, as will be presently described. To this end, the lever fl. is provided with a lateral or side extension 11 adjoining the pivotal point and protruding away from the lever 2, while the lever 2 is provided with a similarly projecting extension 13 overlapping the lever 1. The extension 11 is provided at its extremity with the angular portion 12, while the extension 13 is provided at its extremity with the head 14: complementing or cooperating with the angular portion 12. The angular portion 12 is provided with the longitudinally curved V- shaped rib 15, while the portion 14. is provided with a similarly shaped coiiperating or complementary groove or recess 16. The
upper or outer sides 17 of the rib 15 and recess 16, respectively, are curved longitudinally to conform to the curvature of the can top ring, while the lower or inner faces 18 are flat so as to conform to the flange of the can top ring, the respective members 12 and 1 1, which are in the form of male and female dies, however, being arcuate or curved to conform to the corner of the can top ring between its sides and flange.
The use of the implement as a can top set or wrench need not be explained or reiterated herein, the same being fully described in the aforesaid application, it being noted, however, that the spring serves to open the levers in order that this function of the spring may relieve the hand, and it being further noted that the stop and shoulder conveniently limit the separation of the le vers. These features are also desirable in connection with the dies for truing or setting the flange of can top rings, as willbe apparent.
F or purpose of illustration, a can top ring 19 has been depicted in section in Fig. 6, the same embodying the inturned flange 20 to engage the common glass head of the can top, as is well known. Should the can top be bent, kinked or otherwise out of true, the same may be readily set or trued by the ap plication of the dies 12 and 14 thereover. The dies 12 and 1-1 are normally separated when the levers are opened, in order that the respective dies 12 and 1 1- will engage within and over the corner of the can top ring between the sides and flange. Then, by closing the levers, the dies may be forcibly pressed together so as to set or true the respective portion of the flange 20. By repeating the operation and by moving the ring 19 about, the entire flange 20 may be trued or set. It is to be noted that when the dies are clamped together, the flange 20 will be clamped or pressed between the portions or faces 18 of the dies, while the upper portion of the ring proper will be clamped between the curved portions or faces 17 of the dies, as in this manner, the upper portion of the can top ring proper, as well as the flange, will be trued or set. The particular formation of the dies is such as to permit them to be readily applied to various can top, rings, the levers being disposed approximately tangentially relative to the can ring, and at an angle thereto, or in a plane inclined relative to the can top ring.
As seen in Fig. 7, the adjoining faces of extensions 11 and 13 are convexed and concaved, respectively to correspond with the curvature of the inner edge of the can top ring flange, so that the flange may be set to the proper width.
Having thus described the invention, what is claimed as new is In a device of the character described, a pair of pivoted levers having cooperating dies, the dies having a longitudinally curved coi'iperating rib anc groove, respectively, one side of the rib and the corresponding side of the groove being fiat, and the other sides of the rib and groove being curved longitudinally.
In testimony that I claim the foregoing as my own, I have hereto aff xed my signature in the presence of two witnesses.
