MASON'S TRIG LINE HOLDER Filed Sept. 6, 1950 INVENTOR ATTORNEYS Q Patented Nov. 25, 1952 UNITED s r a s iTET 1 Claim.

This invention relates to a holder designed for use by masons in holding a guide line when laying brick courses, the line being commonly known as a trig line.

The primary object of the invention is to provide a trig line holder embodying a spring arm which is so constructed and arranged that it may be readily positioned over a brick and secured thereto by frictional contact of the ends of the spring arms with the brick, the trig line being removably secured to the holder in such a way that the trig line will be held taut at all times.

Another object of the invention is to provide a holder of this character including line gripping means which will securely grip the line and hold the line against sliding with respect to the holder after the line and holder have been properly positioned.

With the foregoing and other objects in View which will appear the description proceeds, the invention consists of certain novel details of construction and combinations of parts herein after more fully described and pointed out in the claim, it being understood that changes may be made in the construction and arrangement of parts without departing from the spirit of the invention as claimed.

Referring to the drawing Figure 1 is an end elevational view illustrating the application of the trig line holder.

Fig. 2 is a perspective view of the holder.

3 is a side elevational View of a modified form of holder.

Fig. 4 is a sectional View taken on line ti of Fig. 3.

Fig. 5 is a plan view of one end of the holder, illustrating a spring line holding device.

Fig. 6 is a fragmental perspective view illustrating the spring holding device as secured to the line holder.

Referring to the drawing in detail, the holder comprises a body portion indicated generally by the reference character 5, the body portion being constructed of a length of spring steel material having one of its end curved at 6 with its extremity bent outwardly at i, the length of the curved portion ii being such that it will extend an appreciable distance over a brick of conventional size.

The opposite end of the body portion is curved downwardly and outwardly at 8 providing a substantially straight portion adapted to rest on the upper surface of a brick on which the device is positioned, so that the main portion of the body 5 will provide a handle whereby the body portion may be readily removed or positioned,

The end 9 extends downwardly and provides a gripping surface at this end of the body portion to cooperate with the curved portion 5 in clamping and gripping a brick on which the holder is positioned. At the inner end of the end portion 9, at a point where the end portion 9 merges with the end of the downwardly and outwardly curved portion 8, is formed the groove iii through which the trig line extends and in which the trig line is gripped, the trig line being indicated by the reference character A.

As shown by Fig. 3 of the drawing, the holder comprises an arm i i that has one of its ends extended at right angles to the main portion of the arm providing a clamping jaw i2 designed to fit over one edge of a brick to which the holder is secured, in clamping the brick.

At the opposite end of the arm I i is the pivoted jaw l3 which is formed with inwardly extended ears M that have pivotal connection with up standing ears i5 formed on the arm i l.

The reference character i6 indicates an upstanding lug formed with a threaded opening through which the threaded shank I? of the adjusting screw i8 extends, the adjusting screw cont-acting the inner surface of the jaw H3, at a point above the pivot point thereof, so that by moving the adjusting screw in one direction, the jaw it may be moved towards the jaw 82 to securely clamp the opposite side of the brick and hold the device securely in place.

Secured to the under surface or at a point adjacent to the inner clamping jaw 12, is a light spring I 9 which is bent upon itself providing a spring arm 2t and a stationary arm [9, the stationary arm being secured to the arm H, as clearly shown by Fig 6 of the drawing.

The spring is iprrned with a circular portion M for the reception of the trig line used in connection with the holder, the circular portion 2i being so designed that when the device is posi tioned on a brick, and the spring arm 2&3 moves to engage the upper surface of the brick, the arm 28 will move towards the main portion of the spring, securely clamping the line in the circular portion, holding the line against slipping.

From the foregoing it will be seen that due to the construction shown and described, I have provided a holder for securing a trig line used by masons in wall structure, so that the line will be securely held against slippage after it been properly positioned for a guide.

It will also be seen that due to this construc tion, the line may be readily anjusted when desired and then secured to the holder by frictional the arm ii, end of the 3 contact, eliminating the necessity of tying or otherwise securing the trig line to the holder.

Having thus described the invention, what is claimed is:

In a trig line holder, a clamp comprising an elongated body, a stationary clamping jaw formed integral with one end of the body and having an offset portion, a spring member secured to said body with a portion thereof extending into the offset portion of the body, said spring member being bent upon itself providing a spring arm extended outwardly from the body under which a trig line is positioned, said spring arm adapted to clamp said trig line upon movement of said spring arm by contact with a wall over which the clamp is positioned, and a jaw pivotally connected with the opposite end of the elongated body clamping the body to a Wall.
