R. w. MORRISON CONCRETE FORM HOLDER Filed Feb'. 9, 1925 Ross W. {WORK/SON Patented May 26, 1 925.
* UNITED STATES IR-SS W. MORRISDN, O'F WASHINGTON, DISTRICT OF COLUMBIA.
CONCRETE-FORM HOLDER.
Application filed February 9, 1925. Serial No. 7,990.
To all whom it mayconcem: I
Be it known that Ross WV. Moluuson, a citizen of the United States of America, residing at \Vashington, District of Columbia, has invented certain new and useful Improvements in Concrete-Form Holders, of which the following is a specification.
My invention relates to improvements in tying apparatus and is particularly adapted to that type of element used for reinforcing and binding" concrete forms.
The object of my invention is to provide an apparatus of the class described so con structed that it may be easily applied to any form and may be employed for use from one job to another.
A further object of my invention is to provide means for operating the tying element and at the same time looking the same in a secured position around a form.
In the accompanying drawings:
Figure 1 is a side elevation of a form for a ,concrete column having my improved means applied thereon;
Figure 2 is a sectional view taken on the line 22 of Figure 1; 1
Figure 3 is an enlarged detail View of the tying element;
Figure 4 is a sectional view taken on the 1 line 1 of Figure 3, and
Figure 5 is a detail view showing a modified form of the locking element.
In the following description I have dis,- closed my invention as being applied to a vertical column form, the same being made of suitable lumber and comprising boards A secured together by a retaining band B and braced by uprights C. It is to any one of these uprights C that I apply my tying apparatus.
Referring to the accompanying drawings in detail wherein like reference numerals denote corresponding parts throughout the several views, the letter D indicates a main member of the tying apparatus, the same comprising a U-shaped member having a base 1 and legs 2 which is formed of a suitable metallic bar of suitable gauge to stand the strain to be applied thereto, or if desired, the member D may be a casting.
The intermediate portion of the base 1, of the member D, has rotatably mounted therein a stub shaft or bolt 3 which passes through a suitable opening formed in the base 1. That portion of the bolt 3 adjacent its head is cylindrical in form and is provided with spaced openings 4 and 5, the purpose of which will be hereinafter described. The remaining portion of the bolt 3, is squared, as indicated at 6 and a portion adjacent its end is reduced and rounded as indicated at 7. The extreme end portion of the bolt remains squared and is provided with an opening 8 through which a locking.
element 9 passes, the purpose of which will be apparent as the description proceeds.
Slidable upon. the squared portion of the bolt 3, and retained therein by'the lockin element 9, is a second U-sha-ped memberE the base portion of which is provided with a squared opening to receive therein the squared portion 6 of the bolt3.' The base of the member E is slightly longer than that of the member D, so as to permit the member E to embrace the member D, as disclosed in Figure 2.
The openings 4 and 5 provided in the bolt 3, receive therein the end portions of a wire 10 which surrounds the form and so:
connected to the bolt 3 that upon rotation of the latter, the wire 10, will be drawn tightly around the form.
In the operation of the device the wire 10 is placed around a form and the member D is positioned over the uprights C of the form as indicated in Figure 2. In the initial positioning of the device upon the form the U-shaped member E is drawn back to a posi-' tion so that it may rotate without striking the member D, and duringthe rotation, by reason ofthe squared connection with the bolt 3, the latter is caused .to rotate thus winding the wire 10 around the cylindrical portion of the bolt.
member E is moved inwardly upon the squared portion of the bolt 3, until it embraces the member D as illustrated in Fig- After the wire 10 has been drawn tightly around the form the ure 2, thus locking the bolt and preventing tying element without rotating the bolt, and to accomplish this it is only necessary to clip the wire 10 adjacent its connections with the bolt 3. i
In some instances where the width of the timbers used is equivalent to the space between the legs oi the member D, thereby preventing the members from assuming an inclined position as disclosed in Figure 1, it is myv further object, as disclosed in Figure 5, to provide the legs of the member E with slots 11, to receive therein the wire 10-when the member E is moved inwardly to prevent rotation of the bolt.
From the foregoing description it is apparent that Ihave described my invention as being applied to a form constructed for the molding of a column but as will be apparent to those skilled in the art, the tying apparatus may be used in any form of concrete Work where it is desired to reinforce the form externally and prevent the same from breaking under the pressure of the concrete poured therein.
What. I claim as my invention is:
1. In a. tying'a-pparatus of the class described, the combination of a form engaging member and a rotatable member carried thereby, form embracing means secured to the rotatable member, and a member movable upon said rotatable member and adaptedto engage the form engaging member for preventing the rotation of the rotatable member.
2. In a tying apparatus of the class described, the combination of a form engaging member and a rotatable member carried thereby, form embracing means secured to said rotatable member and drawn tightly thereabout upon the rotation of said rotatable member, and a member slidable upon said rotatable member and engageable with the form engaging member for rotating and preventing the rotation of the rotatable member.
3. In a tying apparatus of the class described, a form engagingmember having a rotatable member mounted therein, a flexible element embracing a form and having its ends connected to said rotatable member whereby rotation of the latter will draw said-flexible element about a form, and a member slidable upon said rotatable member and adapted to embrace the form engaging member to prevent the rotation of the rotatable member.
t. In a tying apparatus of the class described, a form engaging member having a rotatable member carried thereby, said rotatable member being provided With a squared portion, form embracing means secured to said rotatable member and adapted to be wound thereon, and a member slidable upon the squared portion of the rotatable member for rotating the same and looking it against rotation.
5. In a. tying. apparatus of the class described, a form engaging member having a rotatable member carried thereby, said rotatable member being provided with asquared portion, form embracing means secured to said rotatable member and adapted to be wound thereon, and a member slidable upon the squared portion of the rotatable member for. rotating the same and embracing the form engaging member for locking the rotatable member against rotation.
6. In a tying device of the class described, a form engaging element having carried thereby a rotatable member, said member being provided with a squared portion, form embracing means secured to said rotatable member, a second elementengageable with the squared portion of the rotatable member for rotating the same, and said second element adapted to slide upon said rotatable member to embrace said form engaging element for preventing the rotation of the rotatable element.
7. In a tying apparatus of the. class described, the combination of a form engaging member and a rotatable member carried thereby, form embracing means secured to the rotatable member, and a member movable ilongitudinally. upon said rotatable member and engageable With the form engaging member for preventing the rotation of the rotatable member.
8. Ina-tying apparatus of the class described, the combination of a form engaging member and a rotatable member carried thereby, form embracing means secured to the rotatable member, and a mem ber slidable longitudinally upon said rotatable member and engageable with the form engaging member for rotating and preventing the rotation of the rotatable member.
In testimony whereof I affix my signature lVitness S. \VIL'roN.
