IMPROVEMENT IN FRAME BUILDINGS.

vSpecification forming part of Letters Patent No. 132,415, dated October 22, 1872.

To all 'whom it may concern:

Be it known that I, LAURAMAN H. RUS- SELL, of Hyde Park, of the county of Norfolk and State of Massachusetts, have invented new and useful Improvement in Buildings; and do hereby declare the same to be fully described in the following specification, and represented in the accompanying drawing, of which- Figure l is a top view; Fig. 2 a side elevation; Fig. 3 a longitudinal section 5 and Fig. 4 a transverse section of the post and two iloorin g-beams of two stories of a house or store, with my invention applied thereto. p

It is well known that, owing to vertical shrinkage of floor-timbers when upheld by posts or partitions, such door-timbers are lia ble to sag more or less, and, as a consequence, cause the floors to sag and the partition to become more or less warped or cracked. In order to prevent such it has been customary to extend each post at its head through the timber, and to rest the foot ofthe post next above directly upon the head of the extension. This is generally attended with the necessity oi' making a large hole through the timber, and as a consequence the timber becomes very much weakened thereby.

In carrying out my invention the timber is much less weakened, as, instead of one hole of large diameter, I bore a series ofsmall auger-holes down through the timber and directly over the head of the post on which the timber is to rest, and I insert in each of such holes an iron bolt having a length equal to the depth of the timber. The lower ends of these bolts rest directly upon the head ofthe post or upon a metallic plate or cap placed on the upper end of such post. On the upper' ends of the said bolts the base of the next post is to rest, or the partition may be erected on them or a cap resting upon them.

In the drawings, A and B denote two floortimbers, one placed over the other; one be-v longing to one door and the other to the next iloor above. Between these door-timbers, and extending from one to the other oi' them, is a post, C, provided at its upper and lower ends with metallic caps or support-plates a b, arranged with respect to the Hoor-timbers A B, in manner as shown. the' upper ends of a series of round pins or bolts, c c c, extending down through the lower timber and upon a rest-plate, d, as shown. A similar series of such bolts, c c c, is arranged in the upper door-timber and so as to extend through it and rest at their lower ends upon the cap-plate of the post, all of which bolts are separate from the posts or the cap-plates thereof. The post D, erected on the second-Hoor timber, is to rest at its (the posts) base on the heads ofthe pins or upon a base-plate placed thereon. In case orn vertical shrinkage of the floor-timbers the posts will be upheld by the bolts and will uphold the floor-timbers so as to prevent them from sagging and the evil consequences thereof. The great advantages of the system of bolts separate from each other and the posts, for giving support to the posts, will readily be apparent to artiiicers or carpenters.

I claim- In combination with a floor-timber, its support or sustaining-posts, and a post to extend up from such timber, a series of bolts separate from each other and the post or support below the timber, and also separate from the post to extend up from the timber, aud arranged substantially as described and represented.
