SPECIFICATION forming part of Letters Patent No. 250,217, dated November 29, 1881.

Application filed July 27, 1881. (No mode 1.)

To all whom it may concern Be it known that I, ANDREW J. DOANE, a citizen of the United States, residing at Indianapolis, in the county of Marion and State of Indiana, have invented a new and useful ImprovementinFerrules with SwiveledOlamp- Plate for Grosscut-Saw Handles, of which the following is a specification.

Heretofore saw-handles have been provided with ahollow plugfor securiugthe nut in which works the threaded end of a slotted belt that holds the saw, the lower end of the handle having a ferrule provided with an integral exterior flange to receive the lugs of a movable washer or swiveled section, which lugs are turned up over said flange. This washer is also hollowed out to accommodate the projecting end of the interior plug, and is grooved or provided with guide-lugs on its under surface, to receive the saw-plate. The several parts of the ferrule as thus made, however, have been formed separately, the lower section or washer being afterward attached to the ferrule proper by bending the lugs or flange of the washer over the annular head or flange of the ferrule. To do this safelythe washer must be made of wrought or malleable metal, and thus involves considerable expense in time and material.

My invention obviates these difficulties, and relates to improvements in ferrules with swiveled clamp-plate for crosscut-saw handles, in which the socket-section of the ferrule operates in conjunction with a swiveled section; and the object of my invention is to provide a socket-ferrule for crosscut-saw handles, with a swivel saw-clamping section cast thereon. This object I accomplish by the device illustrated in the accompanying drawings, in which- Figure 1 represents a view of the saw-clamp end of the swivel-section. Fig. 2 is a section of the entire device, showing the manner in which the two sections of the ferrule are united together and the manner in which a saw-blade is made fast to the handle.

A represents an ordinary crosscut-saw handle with stationary nut D, hole B, and sawholding loop I.

The section E is cast with a recess to receive the end a of the handle A, and a chamber, b, below to permit the upper end of the loop I to enter. The outer surface of the section E is provided with a groove, G, which extends all around theIferrule, near its lower end. The section E is first cast. Afterward the clampingsection F is cast around the base of the section E, and the metal forms the ring R in the groove G, thus producing a swivel-joint.

The form of the lower face of the swivel-plate F is shown in Fig. 1, in which the notches b b in each of the projecting sides is designed to fit over the upper edge of the saw-blade H.

In order to operate my improved ferrule, the saw H is inserted in the clam pin g-loop I. The handle A is then turned until the screw P of the loop is run up in the nut D and the back edge of the saw H enters the-notches b b of the swivel-plate, where the saw is held fast by further screwing the nut D of the handle on the screw P. The handleA and ferrule-section E turn freely on the ring It of the section F.

What I claim as new, and desire to secure by Letters Patent, is

1. In a saw-handle, the combination, with the ferrule section E, having a groove, G, around its lower end, of the saw-clamp section F, having ring R cast in the groove Gr, forming therewith a swivel-joint, substantially as shown and described.

2. In a saw-handle, the combination of the ferrule-section E, having socket above for the end a of the handle, recess b below for the passage of the saw-loop I, and annular groove G around its lower end, and the clamp-section F, having ring R cast in the groove G, forming a swivel-joint, and provided on its under surface with notches b b, with the handle A, having opening B, fixed nut D, and screw I, provided with saw-holding loop I, whereby when the handle is turnedin one direction the said screw is run up through the fixed nut until the back of the saw held in the loop at the end of the screw is firmly engaged with the lower notched surface'of the clamping-section or swivel-plate F, substantially as shown and described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
