Description

J. S. LOOMIS.
SECTIO'NAL PRESSURE BARS P-LANING AND MOLDING MACH ' No. 187.472. Patented F.eb'.Z0 ,1877
\l. PETERi PNDTO-LITHOGRAPHER WASHINGTON D C T OFFICE.
JOHN S. LOOMIS, OF BROOKLYN, NEW YORK.
IMPROVEMENT IN SECTIONAL PRESSURE-BARS FORPLANING AND MOLDING MACHINES.
Specification forming part of Letters Patent N 0. 187,422, dated February 20, 1877; application filed April 6, 1876.
companying drawings, which are lettered to correspond with, and form a part of, the specification.
To enable the public to understand the na ture of my said invention, and those skilled in mechanics to construct and use the same, I will describe it as follows, to wit:
pressure blocks or feet, B, provided with the pressure-roller B, revolving in the block or foot B, upon a fusible metal bearing or journal, N also, the spring chip-breaker A, securedby bolts 1 and 2, and arranged close to the cutter O. a
.Fig. 2 represents the front view of two pressure blocks or feet, B B, provided with only one roller, R, passing through both blocks in a similar manner to Fig. l. A A are chipbreakers, secured to the pressure blocks or feet by the bolts 2 2, and smaller guide-bolts 1 Fig. 3 is a front view of a single pressure block or foot, B, having the chip-breaker A, and provided with a separate roller, substantially as shown at Fig. 1.
cutters G, by which means cross-grained lumber may be passed through the planing-machine with perfect safety, and dressed in a workmanlike manner. The roller R extends across the entire machine, passing through each pressure foot or block B, and is provided with Babbitt-metal bearin gs N.
The above-described pressure-bar, having spring chip-breakers secured to, and forming a part of, the same, for the purpose set forth, Figure 1 is a side elevation of one of my I believe to be novel and useful.
What I claim as novel and useful, and wish to protect by Letters Patent of the United States, is-- a A sectional pressure;bar for planing and molding machines, formed of a series of pressure-feet having a flexible chip-breaker attached to each, and mounted upon a roller provided with Babbitt-metal bearings, all constructed to operate as shown and described, and for the purpose specified.
In testimony whereof I hereunto subscribe my name in the presence of two witnesses.
JOHN S. LOOMIS.
