--Be it known that we, CLAUDEC. SALMONS and JAMES MAHONEY, citizens of the United States, residing at West Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented new and useful Improvements in Combined Clamps and Fasteners, of which the following is a specification, I This invention relates to a combined clamp and fastener for use in-securing variousparts or elements to hollow tiles, walls, blocks, or.

slabs, etc., in building constructions, such as forfastening'chair rails, picturemoldings or the like to hollow walls, or soap cups or the like to marble slabs, etc, or for fastening any article to a surface which requires the surface to be pierced and a holder to be applied to ca'rry'tlie fastening member, and particularly where it is impossible or impracticable to reachthe inner face of the wall or surface to which the article is to be fastened, such as the inner face of one side of "a hollow wall; I I v One'object of the invention is to provide acombined clamp and fastener in which the clamp, to which the fastening member is applied, is adapted to be readily, conveniently,-

firmly and expeditiously applied'to a hollow wall or other surface. I

' A further object of the invention is to provide 'a device of the character described which is adapted for general fastening purposes of the character defined, and which embodies a novel and efficient form of holding clamp to which the screw or other-fastening member is applied.

The invention consists of the features of construction, combination and arrangement of parts,-here1nafter fully described andclaimed, reference being had to the acc om panying drawing, in which through the device. Fig. 8 is a horizontal longitudinal section thereof. 1 1

Fig l is a View similar to Fig.2 showing f tumbler adapted forspecial use.

In carrying .the invention into practice,

we provide a combined clamp and fastener comprisinga body member 1 and a tumbler or retaining member 2,- forming'a clamp, and adapted to be employed in conjunction with fastening 3,such as 'a screw, of. a

suitable type. The body memberl i's'prefferably formed ofbendable sheet metal, and

is provided at itsside edge's'with a pair of parallel upturned flanges 4:. These flanges 4 have forward extensions 5 and rearward 1. extensions -6.' 'The-forward extensions 5 form a'fipair of bendable clamp ng arms or I fingersfof" some suitable length,-which are employed, for a purpose hereina'fter de scribed," while the rearward extensions form supports for the tumbler or. retaining.

member Zand project a comparatively short of the body 1., j

The tumbler or retaining member 2 com prises a solid bar, I of oblong rectangular distance beyond the inner or rear end" 7 I form, which is formed or provided on its side.edges, at a point between its transverse center and one of its ends,'with p vot members orprojections'8'which engage pivot openings 9 formed in the support 6,, whereby said tumbler or retaining member is;pivot ally mounted for swinging movement, from a pos1tion,'such as shown in Fig. 4, parallel with the. body. 1 and "flanges 4, to aposi tion, such as shown in Figs. 1 g- 3, 1n

the first named position, theupperor shorter end of the tumbler 2 folds or extends over upon thelbody 1 and within the groove or recess formed by the flanges 4', while "in the second .named position the tumbler extends vertically between the supports-6 andisheld from lateral movements thereby. V 7

The tumbler 2 is provided, in the form o the invention shown in Figs. 1 to l, inclusive,

with a threaded-opening 10' to receive the 1 fastening member 3, which may be, as shown, amachine screw of suitable length for-the intended purpose; In the slightly modified,

form of the invention shown in Fig. 5 the bar 2 is shown as provided with an opening 11 threaded to receive a wood screw 12, designed for use in securing certain objects which can not be secured by means of a machine screw. It will, of course, be understood" that while a screw type of fastening: is herein disclosed, any other suitable typed of fastening capable of being e1np[loyed for the purpose may be adopted. Inig; 5the bar is provided with a longitudinal slot 11' 7 making the side walls of the opening "11" springyso as to lightly gripthe threadof the screw and hold. the screw from working loose.

' v The device is designed particularly for use in fastening articles to or upon one surface of a wall or othersupport inwhich it is necessary to pierce thewall or support'for the purpose, and particularly for fastening articles to hollowtiles or other walls where itis impossible to secure aecessto the inner side of the wall in order to placea fastening space 16. tl1erebetween..

' itsout'er and inner faces, and; the screw-3 or '12being-removed from the threaded opening in the tumbler or retaineribar,2,'said= baris then swungyto lie in; a plane-parallel with the 7 after which the bar and adjacent portions-of. the clamp are forced longitudinally through 40 body 1 and flanges 4, \as shown in Fig; 4:,

the openinglT until the bar 2 passesbeyond the inner face of the wall 14. In: this operation of introducing the-device th'e bar 2 will be held in the position stated by the-walls of the opening 17 until it passes the inner faceof the wall 14,:whereupon, beingno longersupported, it will be caused to tilt or swing: to a vertical position, parallel withthe inner. face'of the wall'l l. Thistiltinganotion,it

' will beobvious, is dueto the eccentric'pivoting of said bar to the supports 6, whereby its longer or heavier end is adapted to, dropxby gravity when the device is fullyinserted .7 V The'ba'r 2fwill then act-as a retainer -.toahold;

the device from withdrawal from. thexopene ing 17, and may be brought to lievsnugly against the inner'surfaceofthe wall :14 byan outward pull upon the arms or fingersv5. These arms onfingers are then bent laterally in opposite directions asbest seen in *Fig; 3,

to lie against the outer face of the wall '14,

whereupon the device will be:clamped in: po sition upon the wall; The molding 13 or other.

object to be held is thenplaced inposition; against the wall and over the bent portions of,

the arms 5 and the screw 3 or 12 inserted and engaged With openings 10 or 11 in the bar 2 and screwed up, thereby connecting the moldingwith the clamp or retaining bar: and

clamping both firmly against relative movement; It will, of course, be understood that eithera machine screw orra wood screw maybe used, according to the nature or character of V the article which is to be applied and secured in-posit-ion-.-- It will also be understood that the bent portions of the arms 5 may betriinmed down-as required so that they' will be concealedabehind the-objects secured, thus making a neat and attractive finish and entirely concealing the fasteningmeans, with the exception. of the-:head of the fastening .screw,

fromuview: If desired, the head of the fastening screw may be concealed, from view by countersinking it and.otherwise:concealing it 3 by; known methods in-thearticle secured, thus making-the fastening entirely invisible.

Itwill beevident that when so applied-the combined clamp and fastener will be rigidly held invposition and: will form-a firniand suitablensupport for the molding, chair rail" ingorotherarticle-secured to the face ofthe wall, and that .bythe construction and use of the devicein the-manner :set forth articles of various #kinds may be secured to hollow tile wallswith: great ease :and 'conveniencerand Withoutinjury tothe wall. l. Our. improved -,fas tening. may'also: be employedforsecu-ring soap. cups and various otheivarticlesto.walls, marble slabs, andthe 1 like,-or,for fastening any article ,to a surface which requires the-surface tobe pierced'and a holder to beapplied to I carry the fastening member. Thevpivot :tumbler adapts the devicetobe :readily introducedand, 'by' auto maticallyy tilting-,1 to an e operative position, provides a clampingamemben for engaging one sideof an otherwise inaccessible surface of a"wall-;orslab, sowthat the holder and clamping member may'bequickly and efiiciently employed inwplace and: held firmly againstwextractionr: e r Having thus fully described our invention, We claim: 7

the: construction being such ritha-t the. :long sections of the strips may be bent laterally in opposite directions and severed at any point alongtheir length beyond said cross piece whereby to form retaining members of any required length.

2. A bolt comprising a body, retaining means at one end of thebody, a bolt eccentrically pivoted at the opposite end of the body, said bolt having a threaded opening I and a slot intersecting the-same and forrning :7
