ATTORNEYS,

Patented Apr. 26, 1949 UNITED STATES PATENT OFFICE 7 Claims.

This invention relates to a setting gauge for corner beads and is designed to assist a plasterer in making window recesses which are perfectly square and plumb.

In practice, after the Window frames are set and it is desired to apply lath, it is conventional to provide corner beads, particularly at the corners of the window recesses. After the corner beads and the lath are in place, the plasterers proceed with their plastering, and the window recesses will be square and plumb if the corner bead is square and plumb. The preliminary operation of squaring up and making plumb a corner bead is a rather tricky operation requiring a considerable amount of skill and taking a skilled workman perhaps a half hour.

It is an object of my invention to provide a simple setting gauge whereby even an unskilled workman can insure that a corner bead is square and plumb and can complete the setting of a corner bead in about ten minutes.

It is a further object of my invention to provide a device as outlined above which will be simple in operation and inexpensive in construction and convenient in use.

These and other objects of my invention which I shall point out in more detail hereinafter or which will be apparent to one skilled in the art upon reading these specifications, I accomplish by that certain construction and arrangement of parts of which I shall now describe an exemplary embodiment.

Reference may be had to the drawings forming a part hereof and in which:

Fig. 1 is a plan view of the device.

Fig. 2 is an elevational view as seen from the top of Fig. 1.

Fig. 3 is an elevational view as seen from the left of Fig. 1.

Fig. 4 is a partial cross sectional view taken on the line 4, 4 of Fig. 1 on an enlarged scale.

Fig. 5 is a detailed partial bottom view of Fig. 1.

Fig. 6 is a partial horizontal cross sectional view of a building structure showing the device in use.

Briefly, in the practice of my invention, I provide a square comprising the shorter arm I which is preferably of a hard wood and the long arm II which may be of sheet metal and which is provided with the longitudinal slot l2. The member II is held in a slot in the member 10 as by means of rivets I 3. The member I l is provided with a small extension l4 having an edge l which is a continuation of the edge 16 of the member II. A square member indicated generally at IT is arranged to slide along the member II as follows: a plate I8 is provided with a narrow portion I9 arranged to fit in the slot l2 and carries integral therewith a bolt 20; a plate 2! having a turned edge 22 fits over the bolt 20 and the entire assembly is held in place by means of a wing nut 23. It will be clear that by loosening the wing nut, the assembly I! may be adjusted longitudinally of the member II. By referring to Fig. 5, it will be noted that the member 17 carries a notch 24 adjacent the edge II. On the face of the member l1, visible in Fig. 1, there is carried a clamp arrangement indicated generally at 25. The member 25 consists of a pair of crossed arms having finger grip members 26 urged apart by a compression spring 21. The other ends of the crossed arms are provided with hook like gripping elements 28 which are arranged to be positioned in alignment with the notch 24. The member 25 may be bolted to the member I! as at 29 or suitably attached in any desired manner.

The use of the device will be clear from a consideration of Fig. 6 where I have shown a window frame element 39 and a wall structure indicated generally at 3|. A corner bead of conventional type is indicated at 32. It is desired that the bead portion 33 be on a continuation of the window frame edge, indicated at 34. Thus, the square is positioned as shown with the edge l5 engaging the edge 34. The edge It thus forms a continuation of the edge 34 and square with the plane of the window by virtue of the fact that members [0 and II define an accurate right angle. The member I! may now be adjusted to the proper position and the bead 33 may be engaged in the slot 24 by the member 25. If the device fits as shown in the drawing, the plasterer will know that the bead 33 is square with the window frame and he may nail the corner bead 32 to the stud at this point. He may then slide the square down with the member 25 still in engagement with the bead and place the portion [3 against the next lower cross bar of the window and check that the corner bead is plumb. If it is not, he can bend it or slide it by hand until it is, and then nail it at that point. He repeats this procedure all the way down and when he has finished he is sure that the corner bead which is to be his plastering guide is both square with the window frame and plumb.

With the device above described even an unskilled worker can produce work which is square and plumb after a minimum of instruction and in about one third the time that has heretofore been necessary for a skilled worker.

It will be clear that numerous modifications may be made without departing from the spirit of my invention and I therefore do not intend to limit myself except as pointed out in the claims which follow.

Having now fully described my invention, what I claim as new and desire to secure by Letters Patent is:

1. A setting gauge for corner beads comprising two arms having edges defining a right angle, a gauge member having an edge slidable on one of said arms, and. means mounted on said gauge member for gripping of a corner bead. i

2. A setting gauge for corner beads comprising a shorter arm and a longer am, said arms having edges defining a right angle, a gauge member slid able on said longer arm, and means mounted on said gauge member for gripping a corner head.

3. A setting gauge for corner beads comprising a longer arm and a shorter arm, said arms having edges defining a right angle, a gauge member slidabl'e on said longer arm, and a notch in said gauge member tangent to the edge of said longer arm for defining the position of a corner bead.

4. A setting gauge for corner beads comprising a longer arm and a shorter arm, said arms having edges defining a right angle, a gauge member slidable on said longer arm, a notch in said gauge member tangent to the edge of said longer arm, and means associatedwith said notch for gripping and holding in said notch a corner bead.

5-. A device according to claim 4 in which said gripping means comprises a pair of crossed arms pivoted to said gauge member, said arms constituting gripping jaws disposed adjacent said notch, and means for yieldingly urging said jaws to ether.

6. A device according to claim 3 in which one of said arms has an extension pastsaid other arm, said extension havin an inner edge in alignment with the outer edge of said arm.

7. A setting gauge for comer beads comprising two arms having edges defining a,- right' angle, one of said arms having an erltension past said other arm, said extension havin an inner edge in alignment with the outer edge of said first mentioned arm, a slot in said first mentioned arm, a gauge member sl'idable in said slot and having means for looking it in desired position, a notch in the edge of said gauge member tangent to the edge of said slotted arm, and grippin means associated with said notch, said gripping means comprising a pair of crossed arms pivoted to said gauge member, said arms constituting gripping jaws adjacent said notch,- and means for yieldin'gliz urgin said jaws. together,
