ATTACHING CUTTERS FOR UT'IING SCREW S ON RAILS 0F BEDSTEADS.
Specification of Letters Patent No. 8,620, dated December 28, 1851.
To all whom t may concern:
Be it known that I, JACOB ZIMMER, ofthe city of Tiflin, in the county of Seneca yand State of Ohio, have invented a new and useful Improvement in the Manner of Securing V-Shaped Cutters in Rotary Cylindrical Heads for Cutting Screws on Tenons of Bedstead-Rails; and I do hereby declare the following to be a full and clear description thereof, reference being had to the anneXed drawings of the same, making part 0f this specification.
Figure l represents a perspective view of cylinder head and cutter. Fig. 3, is a per- The same letters of reference indicate the same parts on theligures.
I `am aware that V shaped cutters have been secured in rotary cylindrical heads. for cut-ting screws on tenons of bedstead rails, in various ways, such as letting the tapered end of the shank of the cutter, into `a recess on the exterior portion of the cylindrical head and bringing the angular shoulder of the underside of the shank against the smaller end of the opening through which the Y. front part of the cutter projects, and sustaining the beveled points of the latter against the interior beveled surface of the cylindrical head. But I am not aware that V shaped cutters have been confined in rotating cylindrical heads in the manner fol- A in the end of the cylinder head B in such to be placed laterally therein, or inserted sidewise into its seat, and confinedby means of an angular shoulder D formed on the upper side of the shankE and embracing and by angular notches F, F, at the front ot the cutter, embracing that portion of the cylinder, corresponding therewith in form,
and rendered perfectly lirm, requiring no adjustment whatever, the form of the cutter exactly fitting the side, and ends of the opening in the cylinder head. The head of the conning screw bolt G is countersunk in the cylinder, and the shank thereof passes through theshank E of the cutter. The
front ends of the cutter in which are the angular notches F are increased in thickness as seen in Fig. 3, for resisting the thrust 0f` the cutter centerward or otherwise.l during the operation of cutting screws. Having thus described my improvement 1n securing V shaped cutters in rotary cylinder heads for cutting screws on tenons of bedstead rails, I wish it to be understood that all I claim as my invention and desire to secure by Letters Patent, ish
Forming an opening A in the end of the cylindrical head B so as to allow the cutter C, to be placed ther-ein laterally, or inserted into its seat sidewise, and securely confined in the Amanner herein-before set forth whereby the cutter C requires no' adjustment, and is retained firmly in its position.
In testimony whereof I have hereunto signed my name before two subscribing witnesses.
JACOB ZIMMER.
