TOOL FOR STRETGI-IING CHAINS.
Specification of Letters Patent.
Patented Nov. 28, 1916.
Application filed September 13, 1916. Serial No. 119,886.
To all whom it may concern Be it known that I, DONALD FRASER, a citizen of the United States, residing at Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented certain new and useful Improvements in Tools for Stretching Chains, of which the following is a specification.
My invention relates to a tool for stretching and drawing together the ends of chains, being especially adapted for use in uniting the ends of heavy sprocket and conveyor chains.
In the accompanying drawings Figure 1 is a perspective View of a chain-stretching tool embodying my invention. Fig. 2 is a vertical sectional view of the tool.
In the drawings A designates a heavy conveyer chain the ends of which are to be drawn together that they may be united, the tool constituting the subject of the present case being employed for that purpose. The tool comprises a pair of hooks or chain-engaging members adapted to engage respectively with the links at the opposite ends of the chain, and means by which such chainengaging members may be drawn toward each other.
2 represents a rigid bar provided at one end with a hook 3 adapted to engage with a chain link. One face of the bar at the end opposite the hook is provided with ratchet teeth 4. The bar is adapted to be seated in a shoe 5 having a base and side walls or wings 7. at the edges of the base, these wings bounding the seat in which is located the ratchet bar 2 and operating to hold and guide the latter. The shoe is provided with a hook 6 that depends from the base of the shoe and is adapted to engage with a link of the chain.
A hand lever 8 is pivoted at 9 between the side wings 7 of the shoe, and the lower portion of the hand lever is forked as indicated at 10, and between the fork members are pivoted a pair "of pawls adapted to engage with the ratchet portion 4 of the bar 2, one of the pawls','12, havingits connection with the lever above the pivot 9, and the other, 11, below'such pivot. The pawls are of unequal length as indicated in the drawings,
the upper one being the longer so that it is adapted to reach over the shorter and lower pawl, and both being arranged to be in simultaneous engagement with the ratchet bar 2. In using the tool the ends of the chain that are to be united are brought as near together as may be done by hand unassisted.
' Then the tool is caused to engage with the opposite chain sections, the hook of the ratchet bar engaging a link at one end of the chain, and the hook 6 of the shoe engaging a link at the other end of the chain. The hand lever 8 is now moved backward and forward upon its pivot 9, the pawls 11 and 12 at the same time engaging with the ratchet. Whichever way the upper portion of the lever be moved one of the pawls moves in a direction to actuate the ratchet bar so that its hook approaches the hook 6 of the shoe, thus drawing the ends of the link toward each other, while the other ratchet is moved in the opposite direction passing loosely over the ratchet teeth and coming to position to take a new grip upon the bar 2. When the lever is released the pawls operate as retaining detents, holding the bar in the position to which it has been moved and preventing the chain ends from separating.
By arranging the hook 6 as shown, that is, below the pivot 9 for the handle and so that it extends downward beyond the base of the shoe, the tool is directly and firmly supported by one of the parts to be moved thereby, the location insuring that the reciprocation of the handle 8 shall not tend to disengage the hook 6.
What I claim is A tool for engaging with and drawing together the ends of sprocket and conveyer chains consisting of a ratchet bar carrying a hook adapted to engage with one section of the chain, a shoe in which the said bar is seated and'slides, from the base of which extends a hook adapted to engage with the other section of the chain, and a hand lever carrying a pair of alternately actingpawls that engage with the ratcheted portion of the hooked bar, the pivot uniting the hand lever and shoe being directly above the hook carried by the shoe.
DONALD FRASER.
