1,372,226 Specification of Letters Patent.
I Application ,flled larch 26, 1920. Serial re. 868,897. To dZZichmnitmgco lwern:
Be it known that I, JOHN F. HAVEMEYER,
a citizen of the United States, and a resident of Ardsley-on-Hudson county of Westchester, State of New York, have invented an Improvement'in Bar-Spacers, of which the following is a specification.
l The present invention relates to bar supporting and. spacing means for use in concrete construction.
Among other objects, the invention provides a combined bar support and spacer, which may be made up in standard lengths regardless of the requirement of any particularbuilding in WhlCh it may be used, and which ma contain a minimum weight of T is spacer may be easily and cheaply manufactured in large quantities.
Further objects of the invention will ap;
pear from the following description of a pref ferred embodiment thereof. For the purpose of illustration and description, a preferred embodiment of themvention has been selected and shown in the accompanying drawings, wherein,
Figure 1 and Fig. 2 are respective] a top plan view and the side elevation o a bar a support and .spacer constructed in accordance with the invention, E
Fig 3 is a typical CI'OSS-SGOlJlOIl,
Fig. 4 is an enlar d elevation of the spacer showing a rein orcing bar in section supported thereon,
i 5 is a cross-section of the spacer showing the bar in elevation Referring to the drawings, Figs. 1, 2 and 3 show the generalconstr'uction of the device. The combined support and spacer which for convenience will be referred to as a spacer, is preferably made from ordinarydrawn wire 1 of comparatively heavy gage. The wire is bent or formed intothe variousshapes shown in the accompanying drawings. This bending may be done by'any. suitable machine so that an indefinite number of properly spaced supports or supportinglegs 2 are formed. 'ese supports or legs may be bent alternately to op osite sides of a vertical plane as shown in igs. 1 and 3 so that the device will stand properly upon the centering. The supports ma be bent at different angles so that the rein orcing bars may be placed at any desirabledis tance above the centering, If desired the supports or legs may be made of various lengths in order to obtain various he ghts of the spacer above the centering. The supports are connected by straight, horizontal runs 3, 4, 5, etc., of thewire as shown. The point of bending the wire to form the sup orts may be at uniform or varied intervals. he supports are formed by bending the wire at points 6 and 7 to form one of the supports or legs and is then bent to a horizontal posit-ion forming a seat 8 and then at points 9 and 10 to form another support. he wire may be straight between the points 6 and 7 or it may have anextra bend therein as shown at point 11 in Fig. 3. The wire may be bent in suitable manner and at any angle so long as there are suitably formed su orts and seats.
he invention is not-to be understood as being limited to the precise form of supports" and seats as heretofore described as it is possible to form a single leg bent in one direction and to form a seat therewith, and to form at some further distance alon the wire a single support bent in another irection a d to form a seat therewith. It is also to be understood that seats may be formed at any position desirable along the len h nearer together, by the bending machine or this bending may be performed on the job. A reinforcing bar 12 is shown in position in Figs. ,4 and 5 as being supported at three points. This, howev'e1', is not necessary although desirable. The. wire 13 is provided to maintain the reinforcing rod in position, and in this instance, the wire is shown as being wrapped around seat 8 with its ends 14 and 15 extending upwardly on each side of wire 1 as shown in Fig. 3. It
is, however, immaterial as to the'manner in which the holding wire is attached to the supporting wire. For instance, it may be placed under bends 6 and 10 and brou ht up over the reinforcing bar. This holding wire may be placed on the s acer before shipment from the factory or 1t may be at.
tached after the spacer and rods are in position. The holding wires are bent around each other after surrounding the reinforcing bar and may be tightened as secure as Wished to hold the bar in position.
In forming the spacer, any ordinary rolled steel or sprin wire may be employed. The formation of t e seats may be at any desired distance away from the center line of the spacer, and may be bent in any desired shape to receive and hold the spacing bars without the use of holding wire or with the use of such a wire. The strength of the Wire employed to form the spacer ma be determined. by the distance apart of t e supports and the weight of the reinforcing bars em loyed. This must be considered in or er that the weight of the reinforcing bars used would not spread apart the supports or legs so that the bars would be positioned too near the centering.
Such a spacer for reinforcing bars is of great commercial value and the spacer may be formed of any particular size wire and of any particular length, and the same may be nested together for shipping purposes.
I claim:
1. A bar spacer composed of a single, continuous length of relativel stifi' wire, pairs of loops formed from sai wire, said loops being angularly disposed in different inclined planes to form chairs, and means for securing a bar on said spacer.
, 2. A bar spacer composed of a continuous strand of wire bent to provide lateral loops, the immediately adjacent loops being angularly disposed in different inclined planes to form an A-shaped chair, the wire being of suflicient stiffness to insure stability of the loops against normal lateral and longitudinal strains without additional tying means.
3. A bar spacer composed of a single, continuous length of relatively stiff wlre, two closely contiguous loops being formed from said wire, said loops lying in inclined planes at such angle to each other as to form a stable structure, and means for securing a reinforcing bar on the spacer above said loo s.
4. A ar spacer composed of a sin 1e, continuous length of relatively stiff wire, and
airs of loops formed from said wire, said oops being disposed in different inclined planes at such angle to each other as to constitute a stable chair, said planes being parallel to the longitudinal axis of said len h of wire.
n testimony whereof I have signed my name to this specification this 25th day of
