JACOB HIMELBERGER, OF HOLT, MICHIGAN.
FLOORING-JACK.
SPECIFICATION forming part of Letters Patent No. 285,894, dated October 2, 1883,
Application filed April 3, 1883. (No model.)
To all whom it may concern.-
Be it known that I, JACOB HIMELBERGER, of Holt, in the county of Ingham and State of Michigan, have invented new and useful Improvements in Flooring-Jacks; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, which form a part of this specification.
This invention relates to certain new and useful improvements in the construction of flooring-jacks, and is designed for use in the laying of tight flooring, where close matching or joints are particularly desired.
The inventiion consists in the peculiar construction of a rack-bar, in combination with devices for operating the same, and in the various combination of the parts, all as more fully hereinafter set forth.
Figure 1 is a central vertical longitudinal section. Fig. 2 isa top plan View,
In the accompanying drawings, which form a part of this specification, A represents the side walls of my device, which are secured together by suitable girts, a b, upon the lower I11 the front ends of these walls A are properly pivoted or journaled the vertical rods 0, the lower ends of which have secured to them the wing dogs D. j
E represents a lever, the lower end or head of which is bifurcated, and is properly pivot ed or fulcrumed upon the center one of the In this bifurcated head of the lever E is properly pivoted a dog, E, which is designed to engage with the face of the rackbar B, and behind this lever E are properly hung or pivoted upon one of the bolts 12 the dogs G H, the latter of which is a trifle shorter than the former. erly journaled in the side walls at each end A crank-shaft, I, is propand beneath the dogs G H, by means of which said dogs may be released from their engagement with the rack-bar. y
In practice the device is placed over a joist, and the wing-dogs are adjusted to engage with the sides thereof, locking the device firmly to place and forming a resistance against the ac tion of the rack-bar. The end of the rack-bar ist en projected against the edge of the board of flooring which it is desired to lay. A forward movement of the lever will cause the dog F to engage with the rack-bar and press such flooring closely to place, the rear dogs engaging with the rack-bar, holding such rack-bar -to its position while the lever is retracted for the purpose of exerting a greater strain or pressure upon the board. When this board has been properly nailed, the wing-dogs are released and the device readjusted to the joists, in readiness to be brought into use in laying the neXt board.
What I claim as my invention is- 1. A flooring-jack consisting of the walls A A, connected together, rack-bar B and lever E, \Working therein, dog F, pivoted to the lever, dogs G H, connected with the walls, and wing-dogs D, constructed and arranged to en gage with a joist when in use, substantially as described.
2. A flooring-jack consisting of the walls A A, connected together, rack-bar B and lever E, working therein, dog F, pivoted to said lever, dogs G H, connected with the walls, the crank-shaft I, for releasing said dogs from their engagement with the rack-bar, and wing-dogs D, constructed and arranged to engage with a joist when in use, substantially as described.
