DETACHABLE TROWEL-HANDLE.

SPECIFICATION forming part of Letters Patent No, 737,831, dated September 1, 1903. pplication filed February 2, 1908. Serial No. 141,546. (No model.)

To (all whom it put concern:

Be it known that I, FRANK H. FERAUD, a citizen of the Republic of France, residing at Granite, in the county of Madison and State of Illinois, have invented certain new and useful Improvements in Detachable Trowel- Handles, of which the following is a specification.-

This invention relates to certain new and useful improvements in detachable handles for trowels; and it has for its objects, among others, to provide a simple and cheap construction whereby one handle ma be made to serve for a variety of shapes of trowels. It is a well-known fact that a complete set of molders tools embraces several diiferent shapes of trowels, some thick, some thin, some round, others square, and of other forms and each being provided with a handlewhich makes the kit bulky. By my improvementone handle serves for all of the difierent forms of blades, and the latter can be packed in small compass or carried in the pocket. Furthermore, by my invention if the blade or other part of the trowel becomes broken or worn out it can be replaced at small expense. The handle can be readily applied to either form of blade and as quickly and easily re moved therefrom when desired.

Other objects and advantages of the inven tion will hereinafter appear, and the novel features thereof will be particularly pointed out in the appended claims.

The invention is clearly illustrated in the accompanying drawings, which, with the numerals of reference marked thereon, form a part of this specification, and in which- Figure 1 is a perspective view showing a portion of the blade with the handle attached. Fig. 2 is a perspective view of a portion of the blade, showing the dovetailed socket therein. Fig. 3 is a side elevation showing the handle located in position. Fig. 4 is a similar view with the handle unlocked from the blade. Fig. 5 is a perspective View of the lever detached. Fig. 6 is a perspective View of the spring and its legs detached. Fig. 7 is a detail perspective of a portion of the shank.

Like numerals of reference indicate like parts throughout the several views.

Referring now to the details of the drawings, 1 designates a blade of a trowel to which the detachable handle is to be applied. At one end this blade is formed with a raised portion 2, having the dovetailed socket 3, in which the correspondingly-shaped foot or extension 4 on the shank 5 is designed to be slidingly engaged. The shank 5 is provided with the tang 6, upon which is secured a bandle 7 of any well-known form of construction. The shank 5 is provided with the ears or lugs 8, having the openings 9, in which is pivotally mounted upon a pivot 10 the opposite side bars 11 of a plate 12, having the openings 13 for the reception of such pivot and openings 14 for a purpose soon to be described. The back or rear ends of the side portions 11 are provided with the downwardlyextending lugs or teeth 15, which are designed to engage in the notches 16 in the opposite side portions of the dovetailed socket 3 in the end of the plate 1, as seen best in Fig. 3.

17 is a spring-plate attached at 18 to the cross portion of the plate 12, as seen clearly in Figs. 3, 4, and 6, and its upper end is bent, as at 19, to contact with the inner face of the shank 5.

20 is a lever, the side portions of which are provided at their lower extremities with the rounded corners 21 and openings 22 for the reception of a pivot 23, which passes also through the openings 14 of the said bars 11 of the plate 12, as seen clearly in Figs. 3 and 4. 24 represents tongues or projections on the lower ends of the side bars of this lever, as seen clearly in Figs. 1 and 5.

The parts constructed as above described are assembled, as shown, the plate 12 being pivotally mounted on the shank 5 and the lever 20 pivotally mounted on the plate 12. The parts, as shown in Fig. 4, are unlocked and ready for application to or removal from the blade. The lever 20 is pressed outward that is, with its upper end away from the shank and the projections 24 bearing on the foot of the shank, thus raising up the plate 12, so that its teeth or projections 1.5 are out of engagement with the notches 16. In this position the lever is under the pressure of the spring 17, and as soon as the fingers are re moved from the lever the spring causes it to fly back into the position in which it is seen in Fig. 3, when the teeth or projections 15 ICO engage in the notches 16 and the handle is firmly locked in position, the dovetailed foot 4 of course being engaged in the dovetailed socket 3 in the end of the blade. The upper end of the lever 20 may be made so proportioned relatively to the size of the shank 5' that when it is in the position seen in Figs. 1 and 3 it will engage the shank with sufficient force to prevent its shaking. The lever 20 may be readily compressed outward by pres sure on the upper end thereof with the thumb while the other fingers of the same hand hold the handle.

The teeth 15 are always kept in a constant pressure in the notches 16 by the spring 17, thus keeping'the blade from shaking when in position on the handle. Furthermore, if a great strain is produced on the trowel the spring 17 will give up a little and as soon as pressure is removed the spring and the teeth will take their former places. If a rigid lock were used and the trowel were pressed,it would bend the locking device, which would stay bent when the pressure is removed. This objection, however, is overcome by the employment of the spring.

' Modifications in detail may be resorted to without departing from the spirit of the invention or sacrificing any of its advantages.

What is claimed as new is 1. In a trowel, a blade having a socket, a handle having a foot to engage said socket,

and spring-actuated means carried by the handle for locking the same to the blade.

2. In a trowel, a blade having a socket, a handle having a foot to engage said socket, a plate pivotally mounted onthe handle, and a lever pivotally mounted on the plate.

3. In a trowel, a blade having a socket, a handle having a foot toengage said socket, a plate pivotally mounted on the handle, alever pivotally mounted on the plate, and a spring interposed between the shank and lover.

4. In a trowel, a blade having a socket with notches, a handle having a foot to engage the socket, and means carried by the handle to engage said notches.

5. In a trowel, a blade having a socket with notches, a handle having a shank with a foot to engage said socket,a plate pivotally mounted on the shank and having projections to engage said notches, and a lever pivotally mounted on said plate.

6. In a trowel, a blade having a socket with notches, a handle having a shank with a foot to engage said socket,a plate pivotally mounted on the shank and having projections to engage said notches, a lever pivotally mounted on said plate, and a spring carried by said plate and engaging the shank.

7. In a trowel, a blade having a socket with notches, a handle having a shank with a foot to engage said s0cket,a plate pivotally mounted on the shank and having projections to engage said notches, a lever pivotally mounted on said plate, and a spring carried by said plate and engaging the shank, said lever having projections to raise said plate and its teeth from engagement with said notches.

In witness whereof I have hereunto set my hand in the presence of two witnesses.
