Specification of Letters Patent.

Patented Jan.1e,1912.

Application filed May 11, 1911. Serial No. 626,576.

To all whom it may concern Be itknown that I, IVILLIAM O. DALY, a

citizen of the United States, and a resident of Mobile, in the county of Mobile and State of Alabama, have invented certain new and useful Improvements in Blind- Slat Tips, of which the following is a specification.

This invention is an improvement in the slats of blinds and has for an object to provide a novel form of tip whereby to avoid the diiiiculties resulting from the use of the ordinary wooden tip or stud of wooden slats, which have a tendency to break, to become swollen from weather conditions and are otherwise objectionable; and the invention consists in certain novel constructions and combinations of parts as will be hereinafter described and claimed.

In the drawing Figure 1 is a perspective View of the blank from which the tip is made. Fig. 2 is a detail perspective View of the tip ready for application to the blind. Fig. 3 is a perspective View of the tip applied to the blind.

The invention will be found useful in the construction of new slats as well as in the repair of slats already in use, being especially useful in the latter connection as it will avoid in repairing the slats, the disjointing of the entire frame of the blind as the special form of tip provided by my invention permits the application of the tip to the slat without removing the slat from the blind.

As shown, the tip is formed from a blank shown in Fig. 1, of flat metal which is sloped or tapered along one side at 1, is cut away at the other side at one end at 2-, is slit longitudinally from one end at- 3 nearly to the middle of the blank and has a short slit 4 longitudinally in its other end. This forms the blank into what, for convenience of reference, I term the main plate A whose form, by reason of the slit 3 and the cut away portion 2, is that of a wedge tapering toward its slitted end 3 and having the slit 1 in its broad end. This slit 1 forms tongues 5 and 6 which are bent as shown in Fig. 3, in reverse directions so that when applied to the slat B, as shown in Fig. 3, the tongues will extend in opposite directions and will form a broad bearing against the edge of the slat B. The slit 3 forms a long tongue 7 which is bent around a webS to form a stud C which is circular in cross section as shown in Figs. 2 and 3 and forms the pivot of the slat when the latter is applied for use.

In practice the tongue 7 is bent around the web 8 to form the stud and the tongues 5 and 6 are bent as shown in Fig. 2 and the tip is ready for application to a slat. In doing this in repairing a slat the broken tip thereof may be trimmed OE and a slit D be formed in the end of the slat by a pen-knife, saw or other tool without detaching the slat from its operating rod, the stud on the other end of the slat remaining in its socket and then after the stud C has been slipped into its bearing socket, the slat turning on the stud at its opposite end as a pivot may be pressed at its free end edgewise along the tapered edge 1 of the wedge-shape base plate to bring the said base plate and slat into the relation shown in Fig. 3 when the narrow end of the base plate may be turned at 9 alongside the slat, thus securing the tip to the slat so it cannot move longitudinally in either direction and the fitting of the stud in the bearing of the blind frame will cause the said frame to prevent any movement of the base plate out of the slot formed to receive it in the end of the slat.

The construction is simple, economical, easily made and applied and efliciently serves the purpose for which it is designed.

It will be noticed that the pivot stud has its axis approximately in the plane of the flat base plate 1 or in other words, the said base plate equally bisects the cross sectional circle of the stud so that the latter at its base projects equally in both directions beyond the base plate and the base plate can be fitted edge-wise into the end of a slat and extend from edge to edge thereof and operate to hold the stud in proper operative position.

In Fig. 3 a portion of the blind frame is shown at E, partly in section.

The wedge shape as before described, is of importance in that it facilitates the application of the tip to a slat without removing the slat from the frame, as in this operation the tip can be applied with its stud portion in the socket of the frame and the slat be moved laterally edge-wise along the tapered edge of the tip to the position shown in Fig. 3. Then the parts projecting along the opposite edges of the slat at 5, 6 and 9 operate to reinforce and brace the end of the edge is tapered from end to end, the said base plate being inserted in the slit of the slat and having its broad end provided with tongues bent in opposite directions along the corresponding edge of the slat and with the narrow end of the plate bent along this edge of the slat, and a stud integral with the base plate and having its base projecting on opposite sides of the base plate and resting against the end of the slat, all substantially as and for the purposes set forth.

Copies of this patent may be obtained for five cents each, by addressing the Commissioner of Patents,

2. A blind slat provided in its end with a slit extending from edge to edge of the slat parallel with the flat plane of the slat and a tip comprising a stud and a tapered base plate seated in the slit of the slat and means for retaining the platein the slat, substantially as set forth.

3. A blind slat tip comprising a stud and a base plate connected at one edge with the stud and having its other edge tapered from end to end, the plate being of suflicient length to extend approximately from edge to edge of a blind slat when applied fdr use, substantially as set forth.
