UNITED STATES PATENT OFFICE.

HENRY PHILLIP HAMBURG, OF MORRIS PARK, NEW YORK, ASSIGN OR TO CUSHMAN & DENISON MANUFACTURING COMPANY, OF NEW YORK, N. Y., A CORPORATION OF NEW YORK.

HAND N UMBERING-MACHINE To all whom it may concern:

Be it known that I, HENRY PHILLIP HAM- nURe, a citizen of the United States of America, residing at Morris Park, Long Island, county of Queens, State of New York, have invented certain Improvements in Hand Numbering-Machines, of which the following is a specification.

This invention relates to a well known style of hand numbering machines of which there are a number of examples now on the market; and to similar machines,-such, for instance, as line deters, die plate daters &c. They have a main frame of general inverted U-shape through the top of which passes a plunger attached to a wheel frame that is guided vertically in ways in the inner faces of the vertically disposed legs of the main frame.

The invention comprises improvements in the main frame and Wheel frame whereby strength and simplicity and economy of con struction are attained.

In the accompanying drawing Figure l is a front elevation showing the main frame, its base plate and the vertically reciprocating wheel frame: Fig. 2 is a bottom plan view of the machine with the base plate and numbering wheels removed. Fig. 3 shows a side elevation of the machine: and Fig. 4 showsa rear elevation of the machine with the numbering wheels removed.

The main frame 1 when constructed in accordance with this invention may be made of relatively thin sheet metal, and ways or

guides

2, 2, for the wheel frame, in its vertical legs or members be stamped therein. This stamping operation may be performed either before or after the sheet metal blank is bent into the required inverted U-shape. The throwing out of the side of the vertical parts of the frame to form in its inner faces vertical ways or guides for the wheel frame serves to stiffen and strengthen the main frame. As usual the wheel frame 3 carried by the spindle 4 movable through the top of the main frame, is formed or provided with lugs 6 that travel in the ways 2.

The second feature of my invention con- Specification of Letters Patent.

sists in forming these lugs or projections at the bottom of the wheel frame and in such relation to the peripheries of the wheels 5 (indicated in dotted lines) that they act to positively limit downward movement of the frame and its wheels. This construction may be effectively and economically attained by forming the wheel frame 3 of sheet metal bent into U-shape and having at the lower extremity of each of its legs integral outwardly turned lugs 6 that fit and move in the ways 2. These lugs are so disposed that they contact with the base plate 7 and positively limit the downward movement of the wheel frame and prevent the peripheries of the wheels from striking against the edges of the usual opening in the base plate through which impressions are made.

The third feature of this invention consists in applying to the main frame a transverse brace extending between the vertical sides of the frame and located in rear of the wheel frame. Moreover, this brace my constitute a shield or guide for excluding dirt and protecting the engraved peripheries of the wheel from injury. Thus, the brace is shown as a plate 8 extending between the side of the wheel frame and having inwardly extending flanges bolted to the sides of the frame. Thus two beneficial results are effected,z'. e. the main frame is braced and the wheels are protected at the rear. All other parts of a machine of the general character to which this invention relates may be of any appropriate construction and need not therefore be shown and described.

I claim:

1. A machine of the general character described, comprising a sheet metal frame having vertical sides integrally connected at the top and having hollow strengthening ribs serving as guide ways stamped in its vertical sides, and a brace for the frame serving also to protect the wheels made of a separate piece of sheet metal and extending between the sides of the frame in rear of the guide ways.

2. A machine of the general character described, comprising a frame with vertically disposed Wheel frame guides formed in the Wheels to prevent their contact with the base inner surfaces of its sides, abase plate conplate. 10 neeting the sides of the frame at the bottom, In testimony whereof, I have hereunto a Wheel frame vertically movable in said subscribed my name.

Ways Within the main frame and lugs on the HENRY PHILLIP HAMBURG. Wheel frame traveling in said Ways and WVitnesses:

adapted to abut against the base plate and WILLIAM H. SILK,

positively limit downward movement of the MAGNUS J. HANNING.
