UNITED STATES PATENT JOHN E. PARRISH, 0F RICHZMOND, VIRGINIA.

UNIVERSAL ANCHORING Application filed September 17, 1924; Serial No, 738,236.

To all "ac/2.0m it may concern.

Be it known that I, Join? E. Paluusrr, a citizen of the United States, residing at Richmond, in the county of Henrico and State of Virginia, have invented certain new and useful Improvements in Universal An choring Ties, of'which the following is a specification, reference-being had to the ac cempanying drawings.

This invention relates to structural elements for use in building constructions and has for its object the provision of a novel tie device or tie plate provided for the purpose of anchoring together wooden elements, masonry, brick work or for securing woodwork to concrete structures and-the like, these various uses being mentioned only for purposes of illustration and explanation though it should be understood that the device is capable of employment for a multitude of purposes.

An important and more specific object is the provision of a tie device formed as a plute'of desired size and shape slitted and punched at points to define penetrating prongs adapted to be engaged Within woodwork or within plastic material: such as inortar or the like, the holes at the intersections of the slits permitting the passage of securing elements such as nails or the like and the prongs defined by outward pressing of the .zuaterial between the slits acting as c01nbiued anchoring means and nail grips.

Another object is the provision of a device of this character inWvhich-the slits extend outwardly and considerably beyond the hole formed at their. intersections whereby the angular pieces of metal or prongs between theslits will be capable of yielding in the event of the insertion of a nail having a. diameter greater than that of the-hole,

the prongs consequently acting to grip the nail and hold it in itin. 7

An additional ObJBCt is the provision of a place prior to driving device of this character which will be simple and inexpensive in manufacture, easy to applv and use, positive in action, efficient and durable in service, and a general improvement in the art.

With the above and other objects and ad vantages in View the invention consists in the details of construction to be hereinafter more fully described and claimed, and illustrated in the accompanying drawings, in wlnch;

or the like.

l igure 1 is a vertical section through a cement floor construction showing the use of the device in anchoring thereto strips or the like uponwhich floor boards may he nailed;

Fieure 2 a section on the line 2 -2 of Figure 1;

Figure 3 is a detailed elevation looking: at one side of the tie plate Figure 4 is a similar view of the other side;

Figure is a detailed in section. Referring. more particularly to the drawings wherein is illustrated one of the many uses of the device, the letter A. designates a concrete floor upon which are to be mounted the strips B to which floor hoards C are to side elevation partl y be secured. While floor sun aortin stri )s' is h l be distinctly understood that it nia be of any other shape desired and of any size' Naturally the plate must be constructed of metal though the exact naturethereot is immaterial though it is preferable that whatever metal is employed should he galvanized or otherwise coated or treated for the purpose of preventing or reducing likelihood of corrosion under the influence n1 moisture At spaced {mints which are arranged or located preferably in symmetrical relation the plate 10 is torn'icd with intersectinu slits 11 of any desired character. and at the intersection of these slits the material is punched, forced or pressed out to define cir cular holes 12. Th s pain-lung out of the material produces a series oi prongs or tines 13 which project beyond the rear face of the plate, and it is obvious that the outward pressing of the metal spreads the slits 11 as clearly shown in Figures 3 and 4. Likewise the metal is given a concavedformation 14- at the area surrounding the hole. The holes are intended for the passage of securing members such as nails, indicated atD in Figure 1, and the concavity surrounding the holes acts to guide the nails to proper position as they are inserted.

In Figures 1 and 2 I have-shown 110v the device may be used for anchoring a [loor joist or strip to a concrete floor construction. In employing the device in this. capacity, the plates 10 are embedded in the concrete 7 tloor r as clearly shown, while the concrete or other plastic material is more or less soft so that the concrete can pass through or enter within the holes 12 and firmly anchor and embed the plates. Only the lower ends oi the plates are thus embedded, the upper ends projecting above the top surface of the concrete floor. The joists or strips B are laid upon the concrete floor A and against the plates 10, subsequently to which the nails D are driven through the holes in the plates and into the joists or strips B for anchoring them firmly and rigidly with respect to the concrete floor. The ordinary floor boards C are then nailed to the strips B in the customary manner.

If the device be used for holding together wooden structural elements alone it is evident that it will operate to assist the carpenter or other mechanic very materially inasmuch as the plate may be laid against a wooden element, or the wooden element may be laid against the plate, so that upon the application of a light blow upon the plate the prongs or tines 13 will penetrate the wooden element and effect a temporary holding action which will maintain the plate and possibly the other parts in position until the nails can be driven in. The prongs or tines not only dig into and grip the material but also operate to grip the nails and hold them positively and firmly.

1t will be observed that the slits extend outwardly to a considerable extent beyond each hole so that the metal in the prongs or the angle between the slits will yield to dif- 'lerent sizes or any size of nail so as to grip the nail and hold it, thus serving as a third hand for the workman while he uses say his left hand to adjust and hold the structural elements and his right hand to drive the nail. These are important time saving features.

liogically it is unnecessary to use nails at all times, as the device is capable of employment for holding together masonry or brick work, in which event a desired number of the tie plates may be embedded within the iutntar between blocks, stones or bricks of adjacent rows, courses-or tiers.

As a matter of. tact there is no limitation as to the place where the device may be used or as to the employment or non-employment oi? nails or other equivalent securing elements. Furthermore, any desired number o'l. slits may be provided and in l'act l reserve the right to make all such changes in the form and construction as will not depart from the spirit of the invention or the scope of the subjoined claims.

Having thus described the invention, what I claim is 1. As an article of manufacture, a tie plate having a plurality of groups of concenterod prongs, each prong having its tip portion outbent at one side of the plate and its base portion disposed. in the plane of the plate, whereby at each prong group a central opening defined at one side of the plate by the outstanding prong tips is produced, said opening promoting bonding of the tie plate and said outbent tip portions of the prongs forn'iing anchoring means when the tie plate is embedded or partially embedded in plastic substances and whereby, said prong tips may be engaged in ascreed or the like and the base portions of said prongs provide resilient tongues at the sides of each opening for engagement with a securing element entered through the opening to thereby support the same while being driven.

2. In combination, a concrete base, a screed and a tie plate connecting the base and screed having a plurality of groups of concentered prongs, each prong having its tip portion outbent at one side of the plate and its base portion disposed in the plane of the plate whereby at each prong group a central open ing is produced defined at one side of the plate by outstanding prong tips and in the plane of the plate by resilient tongzjucs formed by said base portions, said tie plate being partially embedded in said base and projecting from the base for engagement with the screed, the openings of the embedded portion of the tie plate promoting bonding of the material of the base at opposite sides of the plate, the prong tips providing anchoring means, the resilient tongues surrounding the openings of that portion oi the plate confronting the screed providing means for gripping a securing element entered through the associated opening while being driven, the prong tips of the portion of the plate confronting the screed entering the screed as the securing elements are drivenhome/to thereby provide :u'lditional securing means connecting the tie plate to the screed.

In testimony whereof signature.
