FASTENING nnvron.

Application filed January My invention is an improved fastening device which is particularly well adapted for use in holding a fire place stop or front cover in place, and it consists in the combinations, constructions and arrangements hereindescribed and claimed.

An object of the invention is the provision of a fastening device of the character described which can be adjusted at will to 'vary W the efiective length thereof within a considerable range.

A further object of the invention is the provision of a fastening device of the character described which includes means for i5 holding the fastening device taut or under tension and for preventing displacement of the parts of the fastening device when the fasteningdevice has been applied.

Other objects and advantages of the i11 vention will be apparent from the following description, considered in conjunction with the accompanying drawings, in which- Figure 1 is a perspective view. showing a fire place stop or cover held in place by fas tening means embodying the invention,

Figure 2 is a relatively enlarged fragmenr tary plan sectional view, showing one of the units of the fastening means exhibited in Figure 1, and portions of the fireplace wall and the fireplace stop or front cover,r.espectively,

Figure 3 is a perspective view showing a fastening unit embodying the invention and including a modified form of springtensioning member. p

In Figure 1, the numeral 1 designates a stop or front cover for a'cavity or fireplace (partially shown at 2) in a wall 3. A pair of fastening units embodying the invention in the form now preferred by me are shown in Figure 1 as holding the fireplace stop or cover in place, each fireplace unit being indicated at U. The specific fireplace stop or cover is disclosed and claimed in my prior 5 application for LettersPatent of theUnited' States, Serial #523,309, filed April 15, 1925, 'and will not be" described in detail nor claimed herein; i

As shown to advantage in Figure 2, each of the fastening units U includes an elongated supporting member which may comprise two. elongated bar-like sections indicated at d and 5, respectively. A The section 5 is formed witha longitudinally extending 2, 1926. Serial no. 78,997.

slot 6; The section 1 is formed with a transverse opening 7 adjacent to one end thereof and a suitable fastening device, such as abolt 8 extends'through the opening 7 and through theslot 6 and is threadedly engaged with a nut 9 which can be tightened against the section 5 to hold the sections 4 and 5 against relative longitudinal movements, whereby the effective length of the sections 1 and 5 combined can be varied within a considerablerange, The section 4: is provided adjacent to its free end with a longitudinally extending slot 10 which is enlarged at its inner end or in other words at the end thereof nearest to the section 5,'as indicated at 11.

A right angular cured rigidly to the convex faceof a substantially semi elliptical spring tensioning bar 13 intermediate the length of the spring tensioning' bar. The .second'arni of the'right angular bracket is indicated at 14' and is disposed flatwise against the adjacent or outer end portion of the section 5 of the fastening unit, being connected with the section 5 by a horizontal bolt 16 which extends through aligned openings in the outer end portion of the section 5and the bracket arm 14 and is threadedly engaged by a nut 17 It may be noted at this point that the bracket arm 12 can be secured to the spring bar 18 in any suitable known mannenas by welding. The spring bar 13 is provided with a threaded opening 18 which is formed through the spring bar intermediate thelength of the latter and in register with an opening 19 in the bracket arm 12. The shank of the bolt 20 may be extended through the aligned openings 18 and 19 and may threadedly engage with the wall of the opening 18. This bolt is of sufficient length to extend beyond the plane of the contact portions at the ends of the spring bar 13 when the head of the: bolt is in contact with the bracket arm 12. 7

bracket has anarm 12 se- The contact portions at the ends of the spring-bar areindicated at ,21 and are reversely curved end portions of the spring bar 13 which thus present convexly curved C ntact faces to the inner wall of the fire- P1528 cover 1 when the bolt shank is projected through'an opening 22 in the fire place cover 1, as shown in Figure 2. The extending end portion of the shank of the bolt 20 is adapted to be threadedly engaged by the internally screw threaded sleeve porthereofmay be readily understood.

enlarged end portionll at one end or tion 23 of an adjusting member which may have av knob or like outer end portion or handle indicated at 2 1.

A stud 25 is adapted to be driven into the fireplace wall to extend within the fireplace cross section than the enlarged end portion 111at the inner end of the: slot; 10.

From the foregoing description of the various'partsofthe device, the operation The effective length of the sections '4 and 5 of a fast ning unit embodying the invention is adjusted as desired and the fastening unit then is manipulated to cause the head 26 ofthe ancho 'ing stud to pass through the the slot 'lO. Thefastening unit thenvis moved outwardly until the shank of the anchoring stud has slidin the slot IOagainst the opposite end of the sl'ot lO. The bolt then is projected through-the'opening 22 in the fireplace cover 1 and the adjusting member 282t is tightened on the bolt- 20 against the action of the spring tensioning member 13'until themarginal edge portions of the fireplace cover have been drawn tightly against the-front-face of the fireplace wall and thespring tensioning member l3-has been elongated from the position-shownby the full lines in Figure Q to the position indicated by the dot-ted lilies in thesame figure. 'The spring member .13 therefore serves not only to hold the fastening unit under tension and taut but also-tends-toprevent'accidental displacement of the adusting member-2324 "from a desirable position on the bolt 20.

It will be understood that whentwo of the fastening units v U'are employed to hold the fire-place coverjin place as shown in Figure 1, said fireplace cover has two of the openings 22 which respectively are-located adjacent to opposite sideedgesofthe fireplace cover. Also, two of the anchoring studs 2526 are provided, the "respective anchoring studs extending into the fireplace or cavity from opposite side walls .ofthe latter.

The modificationshownin Figure 3is identical with the fastening unit here1nbefore described and 111 addition-includes a second spring tensioning member, indicated 7 at 33. The spring member 33a-lso is semielliptical in 7 form and is provided intermediate its ends with an opening 3 1 through which the shank of the bolt 20 extends. The springmember 33 is arranged at right angles to the spring member 13 and. has the end portions thereofcu'rved reversely as indicated at 35 so as to present convexly curved contact facesto the inner wall of the firethat the effective length -meansconnecting the said registering openings beyond place cover,

- that the posed at a lower level than the openings lathe-fireplace cover so that the tighten ng of the fastening devices will draw the fire place cover firmly down against the hearth as well as against the front wall of the .fireplace structure. If desired, 5 may use a softwire of sufiicient strength to connect the stud 2526 withthe member 14 in lieu the'bars 4 and 5.
