RATCHE'I SEAL-PRESS.

Specification of Letters Patent.

To all whom it may concern:

Be it known that I, EDWARD J. BROOKS, a citizen of the United States of America, and a resident of East Orange, in the State of New Jersey, have invented a new and useful Improvement in Ratchet- Seal- Presses, of which the following is a specification.

This invention is additional to my improvements in ratchet seal presses set forth in United States Letters Patent No. 813,079, dated February 20, 1906, No. 727,890, dated May 12, 1903, and previous patents therein referred to. It is more particularly additional to my invention set forth in Letters Patent- No. 595,282, dated December 7, 1897, in which a preferred form of the ratchet rack is integral with one of the cheeks of the die-inelosing head, and the pawl-inclosing housing is carried by one of the lever handles. There has been some trouble, in practice, with seal presses made under this patent for the want of su'llicient oil on the teeth. The operative to whom the press is intrusted is supposed to oil it every day; but does not always attend to this.

The leading object of the present inven tion is to provide for keeping the ratchet rack effectively oiled without complicating the seal press.

Other objects will be set forth in the general description which follows.

A sheet of drawings accompanies this specification as part thereof.

Figures 1 and 2 are respectively a side view and a top view of a ratchet seal press embodying the present invention; Fig. 3 represents a larger side view of the head portion of the seal. press with the improved pawl-inclosing housing in section"'on the line A li Fig. 2; Fig. 4 is a like view with the movable lever handle in its alternative position of rest; and Fig. 5 is a side view of another form of the improved seal press.

Like reference characters refer to like or corresponding parts in all the figures.

The improved seal press, in either of its forms, includes a pair of dies 1 and 2, or 1 and 2, which may be of known or improved construction and adapted to press-fasten seals having either compressible seal parts or interlocking sheetmetal shackle ends to be acted on by the seal press. Other features common to the two forms shown in the drawings are a dieinclosing head, 3 or 3, having an arc-5 shaped full-stroke ratchet rack, 1, integral. with the edge of one of its cheeks; a spring pressed full-stroke pawl, 5, constructed and arranged to interact with said rack, and with reversing notches, 0 and 7, at the ends of the rack; a die closing lever handle, '8 or 8, carrying the housing 9 of said pawl, and fulcrumed in the head 3 or 3 by a pin, 10, with which the rack a is concentric; and a second lever handle, 11 or 11, connected with the head 3 or 3 and opposed to the lever handle 3 or R.

The improved pawl. inclosing housing 0 is of one and the same construction in both of the two types of press to which it is shown applied. (Compare Figs. 3 and 4 with Fig. 1 or Fig. The body is preterably and conveniently integral with the lever handle 8 or 8 and is extended and recessed to form tubular oil chambers, 12 and 13, on both sides of the recess, let, which .in closes the pawl 5 with its follmver, 15, and spring, 10, and is crossed by its pivot, 17; this pivot being parallel with the fulcrum pin 10. Said oil chambers 12 and 13 are perpendicular to the open tace of the housing, at which they are also open; axial tapped holes, 18, 19, communicate with their outer ends; and plugging screws, 20, 21, normally closing these holes oil tight, provide for periodically opening them to inject oil, or to force out the fibrous filling of waste or wick with which each chamber is supplied as means for holding the oil. and feed ing it to the rack. It is necessary to renew the wick or waste occasionally in order to keep the chambers supplied. with a filling properly saturable with the oil. to keep the rack wet without leakage. The open end of the housing 0 has a lip, 22, Fig. 2, which overlaps the rack 4t and one or both of the reversing notches 6 and 7, to prevent or resist tampering with the pawl 5.

In the specific seal press represented in Figs. 1 to 1-, inclusive, the movable die 2 slides in the head 3; the dies are closed by a cam 23 on the pivot end of the lever handle 8; the dies are opened by a blade spring, 24:, reinlorced by a coiled spring, 25, interacting with said movable die; and the second handle 11 is rigidly united with the head 3, being integral therewith.

In the type of the in'iproved press represented in Fig. 5, the movable die 2 is carried by the head end of the second lever handle 11; the latter being tulcrumed in the head 3 by a pin 26 parallel to the fulcrum 10; the dies are closed as in the other type by a cam 23 on the pivot end of the lever handle 8; and the dies are opened by a coiled spring 2% interacting with the die end of the lever handle 11.

It will be understood that the details of the respective types of seal press form no part of this invention, apart from the improved pawl inclosing housing applicable thereto in common.

The external shape of the housing 9 is immaterial; one of the oil chambers 12, 13, with its appurtenances, may in some cases be omitted, and other like modifications will suggest themselves to those skilled in the art.

Having thus described said improvement, I claim as my invention and desire to patent under this specification:

1. An improved ratchet seal press having a pair of seal fastening dies, a dieinclosing head constructed with a cheek an edge of which forms an arc-shaped tullstroke rack, a spring-pressed pawl interacting with said rack, means for opening the dies, a pair of lever handles one of which carries die closing means, a pin concentric with said rack on which this die closing lever handle is fulcrumed within said head, a pivot parallel to said pin on which said pawl reverses, a pawl inclosing housing carried by said die closing lever handle, said housing having an open face adjoining the full-stroke rack and charm bered to hold rack-oiling material exposed by said open face, and means for replenishing the oil.

2. "in improved ratchet seal press having a pair of seal fastening dies, a die-inclosing head constructed with a cheek an edge of which forms an arc-shaped full-stroke rack, a spring-pressed pawl interacting with said rack, means for opening the dies, a pair of lever handles one of which carries die closing means, a pin concentric with said rack on which this die closing lever handle is fulcrumed within said head, a pivot parallel to said pin on which said pawl reverses, a pawl inclosing housing carried by said die closing lever handle, said housing being con structed with an open face adjoining said rack and having a central recess within which said pawl is pivoted and chambers on both sides of said recess perpendicular to said open face of the housing adapted to contain rack-lubricating fillings saturable with oil, said housing having also screwtapped holes communicating with the outer ends of said chambers, respectively, and plugging screws by which these holes are normally closed oil-tight, substantially as hereinbefore specified.
