Description

May 26, 1931. M. M. HEINY ETAL CHAIN REPAIRING TOOL Filed Aug. 27, 1950 Patented May 26, 1931 UNITED STATES PATENT OFFICE MATTHEW MAYS HEINY AND IRVIN B. SMITH, OF HAXTUN, COLORADO CHAIN REPAIRING TOOL Application filed August 27, 1930. Serial No. 478,238.-
This invention relates to a tool for use in making repairs to chains of that type utilizing links having interfitting terminal hooks forming rolling connections.
Heretofore considerable diiiiculty has been experienced in separating the links for the purpose of making repairs and adjustments.
his has been due to the fact that it has been necessary to force one link laterally relative 9 to the other link engaged thereby in order to separate them, and no means has been devised for properly supporting one of the links while the other is being shifted.
It is an object of the present invention to provide a holding block having means for engaging links of different sizes in such a manner that other links connected thereto can be driven laterally out of engagement therewith without danger of destroying any of the parts and without requiring the use of any special supplemental tools.
-With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination 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 may be madewithin the scope of what is claimed without departing from the spirit of the invention.
In the accompanying drawings the preferred form of the invention has been shown.
In said drawings Figure 1 is a top plan view of the tool showing two links of a chain in engagement therewith preparatory to disengaging them from each other.
Figure 2 is a front elevation of the structure shown in Figure 1.
Figure 3 is an end elevation.
Referring to the figures by characters of reference 1 designates a block of steel or any other suitable material which, if desired, can
be provided with an opening 2 for the reception of a screw by means of which the block can be attached to a work bench or the like. Furthermore, if desired, the top of the block may be recessed as at 3 to lighten the structure.
The block can be of any desired configuration. In the present instance it is formed with four separate bores 4 extending therethrough from top to bottom adjacent to the margin of the block. Each of these bores has an eccentric counterbore 5 at its upper end forming a crescent shaped shoulder 6 one end of which is flush with the bottom of a groove 7 in the top of the block and extending through the side thereof.
A slot 8 extends into each bore at an obtuse angle to the groove 7 and intersects the shoulder 6. The lower end of the slot 8 is enlarged as shown at 9 to provide an outlet through which a detached link can be withdrawn. I
WVhen it is desired to separate two links of a chain, one of these links A is placed on edge in the groove 7 so that its large split sleeve B will rest on the shoulder 6, the slot C in said sleeve registering with the slot 8. The other link D which is to be removed, will be supported in slot 8 as shown. With the parts thus arranged a small hammer or other 5 convenient tool can beused for driving link D downwardly within slot 8, and'as the thickness of the block 1 below shoulder 6 is greater than the width of said link D, it will be 'ap parent that the link will thus be withdrawn entirely from engagement with sleeve B.
When it is desired to join two links, link A is placed in the groove and counterbore as already explained, and link D is placed in the upper end of slot C, after which it can 35 be driven downwardly until properly seated in sleeve B.
As is shown in the drawing the bores 4, counterbores 5 and grooves 7 are of diflerent sizes so as to accommodate links of different sizes. In the present instance the tool can be used in connection with four sizes of links, but it is to be understood that thenu'mber of sizes which can be repaired or adjusted can be increased by adding to the number of bores, counterbores, etc., and making them of the proper size, or sizes, to accommodate the links to be acted on. Also, if desired, the block can be made with a single bore only for use with links of only one size.
What is claimed is 1. A tool of the class described including ablock having a bore therein provided With a counterbore and a groove in communication with the counterbore, said counterbore and groove being adapted to receive one end portion of a link and support it on edge,
there being a slot extending into the block and communicated With the bore and counter bore for receiving a second link when displaced downwardly relative to the first named link.
2. A tool of the class described including a block having a bore extending therethrough and a slot extending from the bore through the side of the block, there being a counter,- bore in the block at one end of the bore and a groove in one face of the block extending froin the counterbore through one side of the block.
3. A tool ofthe class described including a block having a bore extending therethrough and a slot extending from the bore through the side of the block, there being a counterbore ,in the block at one end of the bore and a groove in one face of the block, said groove and-counterbore being of the same depth and said slot being extended throughout the length of the bore and counterbore.
at A tool of the class described including a block having a bore extending therethrough, and a slot extending from the bore through the side ofthe block there being a counterborein the blockat one end of the bore and a groove in one face of the block, said groove and'counterbore being of the same depth and said slot being extended throughout the length of the bore andcounterbore, the lower portion of the slot being enlarged to provide a lateral outlet.
Iii testiinon v that We claim the foregoing as our own, we have hereto affixed our signatui'es.
