IMIROVEMENT IN DEVICE FOR BLOO'KING CHAINS.

T0 ALL WHOM IT MAY CONCERN:
Be it known that I, PETER KENDRICK, of Trenton, in the county of Mercer, and State of New Jersey, have invented a new and improved Device for Blocking Chains; and I do hereby declare thatthe following is a full, clear, and exact description thereof, which will enable those skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part of this specification.
This invention relates to a new and improved device for facilitating the driving of wooden blocks in chains, such as are used for mining purposes. f
In the accompanying sheet of drawings- Figure 1 is a side sectional view of my invention, taken ir: the line a: x, iig. 2.
Figure 2, a plan er top view of the saine. 4
Figure 3, a transverse vertical section of the same, taken in the line y y, g. l.
Figure 4, a view of a portion of a chain, showing a wooden block driven through one set of long links.
Similar letters of reference indicate corresponding parts.
A represents a cast-iron box, of rectangular form, and mounted on four wheels, B, which are fitted on suitable ways or guides. l
This box is cast quite heavy, so that it will be fully capable of sustaining the jars and concussione to which it is subjected in driving the wooden blocks through the links of the chain.
The box A is openat both ends and at the top, and Within the box there is placed an upright partition, C, which is movable or adjustable.. i
On each ond of the bottom, eX, of the box A there are two transverse strips, a a', which are in line with each other, a space, b, being between them, as shown clearly in tigri?.
The chain to be blocked is composed of two diierent-sized links, D D', the former, D, being considerably longer than the latter, D, three lengths of links D D being placed side by eide to form one chain, and connected by wooden blocks, E, as shownin g. 4.
After the links of the several lengths of the chain have been welded together, the chain is adjusted edgewise in the box A, the latter containing seven or more links, according to its size, and these links are clamped firmly in position by the partition C, which is acted upon by screws F, as shown clearly in gs. 2 and 3.
The small links Dof the lower length of links within the box rest upon the bottom, aX, of the box A, but the small links beyond the ends of the box A having no support, the strips a a serve that purpose, asthe long links D rcst upon said blocks, (see g. l.)
By this means, the portion of the chain within the box A may be adjusted in proper position with the greatest facility, as the portions of the chain at the ends of the box are properly sustained.
When a portion of a chain is clamped in the box A, a wooden block, E, is driven, by hand, through each set of links D within the box, the partition C is relaxed or unscrewed, and the box A moved along, and another portion of the chain clamped in it, and the long links blocked, as before.
The blocks E are prevented from slipping out from the links D by means of nails, c, driven into the ends oi the block at the outer sides of the end-links, as shown in iig. 4.
I claim as new, and desire to secure by Letters Patent- The box A, provided with the movable partition C and screws F, in combination with the strips, a a', at the ends of the bottom, ax, ofthe box, for supporting the long links D at the ends of the box, substantially as and for thepurpose specified.
PETER KENDRICK. Witnesses ALBERT J. Wnrrrnxnn, Enr GREENWOOD.
