PRUNING IMPLEMENT.

To all whom it may concern:

Be it known that I, ARTHUR M. 'OTTINGER, a citizen of the United States, residing at Springtown, in the county of Benton and State of Arkansas, have invented certain new and useful Improvements in Pruning Implements, of which the following is a specification.

This invention relates to pruning implements.

An object is to provide an implement embodying all of the tools needed in pruning trees or the like, such as a cutter, a saw, and a brush arranged for applying paint on the stump where the branch has been out.

Another object is the provision of peculiar mounting means for the saw making the same detachable, and a further object is to provide peculiar locking means for coiip- '2, as at 5.

eration with the brush to lock the saw in operative position.

WVith the above and other objects in view,

this invention consists in the construction, combination, and arrangement of parts, all as hereinafter more fully described, claimed and illustrated in the accompanying drawings, wherein Figure 1 is a side elevation of the pruning implement; Fig. 2 is an edge view partly in section; Fig. 3 is a section on the line 3-3 of Fig. 1; Fig. 4 is a perspective detail of a portion of the saw; Fig. 5 is a section on the line 5-5 of Fig. 1; Fig. 6 is a fragmentary detail view of the pruning handle; and Fig. 7 is a section on the line 77 of Fig. 2.

Throughout the following detail descrip tion and on the several figures of the drawings, similar parts are referred to by like reference characters.

Referring to the drawings, at 1 is a handle carrying at its upper end a cutter 2 con structed in the usual manner with a hook forming the part 2 and the cutter part 3 having an arm 41 extending therefrom. The cutter 3 is pivoted to the hook formed part The cutter 2 has a peculiar shank 6 to provide a sliding bearing for the saw 7, said shank being formed with a flange 8 and in slightly spaced relation thereto a flange 9. The space between said flanges 8 and 9 forms the way in which the saw 7 is mounted for reciprocating movement. At 10 is indicated an enlargement on the flange 9 having out therethrough a Specification of Letters Patent.

recess 11, the purpose of which will hereinafter be disclosed.

The saw has the usual blade, at the rear end of which is formed a guide stud l2, and opposite said stud. a member 13. The pull rod 14 is pivotally connected wit-h an operating lever 15. The guide stud 12 is adapted to be received in a longitudinal slot 16 located in the shank 6 and extending downwardly from the opening 11. It will be noted that the size of the opening 11 is sufficient to permit the head 12 of the guide stud 12 to pass therethrough when disconnecting the saw from the pruning implement.

The handle 15 has peculiar mounting to facilitate the disconnection of the saw and the operating handle for said saw. This mounting consists of a bracket 17 having an angular flange 18 and a T-formed head 19 received in the T-slot 20, said T-slot being cut at the lower extremity of the handle 1, and at the upper end of the slot is formed a rectangular opening 21. The purpose of the recess'21 is to admit the T-formed head 19 when the bracket is assembled to the handle, said bracket being locked in place by a catch 18 which is pivoted at the ends of the flange 18 and swung into engagement with the recess 21.

It will be noted that the distance between the opening 11 and recess 21 is such that when the saw attachment is assembled on the implement, the T-head 19 may first be inserted in the recess 21 and the operating lever 15 is swung to its uppermost position for engagement with the flange 18, whereupon: the head of the guide stud 12 can readily beentered through the opening 11. When the bracket 17 is pulled downwardly to its lowermost position, as illustrated in Fig. 2, the guide stud 12 has passed downwardly in the slot 16 and therefore the saw cannot by accident become disengaged from said recess 11 in the operation of the saw.

In pruning trees it is customary to protect the cut by applying paint or the like thereto, and for this purpose a brush 21 is provided, said brush being pivoted to a flange 22 extending laterally from the shank 6 and bent to engage the opposite side of the handle to that which is engaged by the flange 8. Through a link 23 the brush is connected fon operation to an operating lever 24 and when not in use, the handle 0 may be locked in a parallel position to the handle by the operating lever cooperating with a catch 25 fastened on the side of said handle. Under some conditions it is desirable to look the saw in inoperative position and, for that purpose, the spring actuated locking pin 26 is .provided, coacting with a cam portion 27 carried by the brush 21. The spring actuated pin 26 is brought into engagement with the saw only when the brush 21 is directed into its inoperative position.

Having thus fully described my invention, what is claimed as new is 1. In a pruning implement, a handle, a

cutter carried thereby, said cutter having a shank formed with a guide Way, a guide slot communicating with said guide way, an enlarged opening adjacent to the end of said guide slot, a saw having a stud and an 0perating bracket formed thereon, a pivotal bracket having an angular flange, a catch pivoted to said flange, said pivotal bracket having T-slot connection with the aforesaid handle and the catch communicating with the handle to lock the pivotal bracket in operative position, and an operating lever pivotally carried by said pivotal bracket and associated with the saw for operation thereof.

2. In a pruning implement, a handle, a cutter carried by said handle, a brush pivoted to said handle, an operating lever pivoted to the handle, a link connection between by the aforesaid guide slot and an operating bracket extending from said saw, a

catch pivotally connected to said flange cooperating with the handle to lock said pivotal bracket in position, an operating lever pivotally connected to said pivotal bracket having link connection with the aforesaid operating bracket, said operating lever coacting with the aforesaid angular flange to limit the movement of the lever, a brush pivotally connected to the aforesaid shank, an. operating lever carried by the handle, a link pivotally connecting said brush and operating lever, means to lock said operating lever in inoperative position, and a spring catch coacting with the brush for locking the saw in inoperative position substantially as set forth.

4. In a pruning implement, a handle, a cutter carried thereby, said cutter having a shank formed with a guide way, a guide slot communicating with said guide way, an enlarged opening therebetween adjacent to the end of said guide slot, a saw mounted in said guide way, a guide bolt carried by the saw and adapted to cooperate with said guide slot, a retaining head carried by the guide bolt and adapted to pass through the aforesaid opening when assembling the saw to the implement, an operating bracket also carried by the saw opposite to said guide stud, a pivot bracket having an angular flange, a catch pivoted to said flange, said pivot bracket having T-slot connection with the handle to lock the pivot bracket in position, and an operating lever carried by said pivot bracket and associated with the saw for operation thereof.

In testimony whereof I affix my signature in presence of two witnesses.
