bar, and one wherein the finger will, when in applied position, be maintained'rigidly in place.

IVith these and other objectsin view, the

invention comprises the novel features of construction and combination of parts hereinafter more fully described.

In the accompanying drawings, Figure 1 is a side elevation of a guard-finger embodying the invention, showing the same in applied position, the supporting bar being indicated by dotted lines. Fig. 2 is a top plan view of the guard. Fig. 3 is a'detail sectional view taken on the line 33 of Fig.

Referring to the drawings, 1 designates the supporting bar of a mowing machine and to which is attached a guard finger 2 which, except as hereinafter explained, is of the usual construction and material and provided with a guide-slot 3 to receive the In accordance with my invention, I cast orotherwise ferin integral with and to project upwardly from the top face of the bearing portion 4L, a centrally-disposed engaging member or stud Gof square or other suitable non-circular form in cross-section to fit a correspondingly shaped opening.

formed in the bar 1, said stud, which iscof gradually diminishing taperlfromits lower toward its upper end, being provided at its upper end with a reduced screw-threaded shank 7 adapted to receive a retaining nut 8 which, when applied, bears on the upper.

face of the bar 1. It will thus be seen that the stud is of substantially pyramid form and is provided with an upper face disposed in line with the guideslot 3 in order that the upper face of the supporting bar may lie flush with the lower edge of the said guide slot. r

In practice, the guard fingers, of which of course the usual number will be employed, are connected to the bar 1 by entering the members or studs 6 upward through the respective openings in the bar and applying the retaining nuts 8 to the threaded shanks 7, under which conditions each finger will be maintained rigidly in place owing to the provision of the square stud 6, which enters the correspondingly shaped opening in the bar and the shoulder 5 which bears at the forward edge of the bar.

It is to be particularly observed that owing to the stud being of diminishing taper from its lower toward its upper end,

its entrance into and removal from the openmg is facilitated, whlle at the same time the action of applying the nut serves to wedge the stud securely in the opening for obviating any possible looseness or lost play be tween the parts, and furthermore that by passing the stud upwardly through the bar 1 with the nut applied on the upper face of the latter, the nut is rendered highly accessible for removal when circumstances require.

' 1 Having thus described-the invention, what I claim is In mechanism of the class described, thecombination with a finger having a guide slot, sald finger having a bearing portion,

an upwardly extending stud of substantially a passage conforming to the shape of the stud to receive the same, a shoulder upon the bearing portion engaged with the front face of the bar, and a clamping nut engaged with the threaded stem and frictionally engaged with the supporting bar.

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