LOCKING-HOLDER FORROLL MATERIALS.

SPECIFICATION forming partV of Letters Patent No. 774,937, dated November 15, 1904. Application filed February 23, 1904. Serial No. 195,126. (No model.)

To @ZZ whom it may concern:

Be it known that I, CHARLES F. CRAMER, a citizen of the United States, residing at Scranton` in the county of Lackawanna and State of Pennsylvania, have invented a new and useful Holder for Rolled Materials, of which the following is a specification.

This invention relates to that class of holders for roll materialssuch as toilet and wrapping paper, ribbon, tape, twine, and thel like comprising a plate intended for permanent attachment to a wall, pivoted hanger-arms pendent from the plate, and a roll support or bar held between the free ends of the hangerarms and consisting of interlocking sections capable of being separated only when the material is wholly unwound, thereby preventing the removal of the r'oll bodily.

One of the objects of my invention is to provide in a device of this character an improved and novel arrangement and construetion of detachable hanger-arms and sectional roll support or bar` which include means for locking both at the walL-plate and at the rolsupport and in which, more specifically, each section of the support forms practically a permanent part of the respective hanger-arm to which it is attached, necessitating the removal of one or both of the arms from the wallplate to effect the separation of the interlocking roll-support sections, and there being also provision made whereby one or both hangerarms can be so withdrawn only by swinging it to a certain elevation and then only when the lockingmechanismof the roll-support has been exposed and unlocked after the roll has been wholly unwound.

Another object is a sectional telescopicroll support or bar which is capable of assuming locked positions of diiferent lengths or eXtensions, so as to accommodate rolls of widelydiiferent widths.

A further object is to provide improved concealed and protected means for journaling the sectional roll-support to the hanger -arms; and a further object is in general to provide a holder for roll materials in which the parts can be easily and cheaply made and readily assembled and which will be effective in operation and durable.

Figure lis a front view of that embodiment of my invention in which the roll-support is constructed entirely of metal. the latter being shown in section. Fig. 2illustrates in juxtaposition the two sections of the rollsupport separated. FigA 3 is a transverse section taken substantially onthe line 1 2 of Fig. 2 as the parts would appear if assembled. Fig. 4. is a longitudinal sectional view of the roll-supportand the ends of the hangerarmsto which it is attached and illustrates the journaling means. Fig. 5 is a transverse sectional view taken on the line 3 4 of Fig. 4. Fig. 6 is a view illustrating one of the washer-headed screws used to journal the roll-support sections to Vtheir hanger-arms. Fig. 7 is a longitudinal sectional View of a modification wherein the rollsupport is formed partly of wood. Fig. 8 is a section thereof on the line 5 6 of Fig. 7. Fig. 9 illustrates that form of screw-washer employed at the right-hand end of the roll-support shown in Fig. 7. Fig. 10 is an elevation of theright-hand end of the holder, showing roll held and illustrating in dotted lines the different positions of the right-hand hanger-arm in the bayonet-joint-interlocking operation, the studded arm following slots shown in Figs. 12 and 13. Fig. 11 is a similar view of the opposite side of the holder, the studded arm following slots shown in Figs. 14 and 15. Figs. .12 and 13 are detail views illustating the bayonet -joint connection between the right-hand hanger-arm and the barrel of the wall-plate. Fig. 14 and 15 are similar views of the other 'hanger-arm.

The plate that is intended for attachment to a wall is provided with a barrel A for the reception of the hanger-arms B. These latter are designed for detachable pivotal connection with the barrel A, and for this purpose a bayonet-slot and stud-joint is provided for one or both of the arms. As illustrated in Figs. 10 to 15, inclusive, each end of the barrel A is formed with a bayonet-slot C, designed to accommodate a stud D on the end ofthe respective hanger-arms, thereby forming interlocking means between the barrel and arms, and it is to be especially noted by referring to Figs. 10, 12, and 13, which illustrate in dotted lines the entering and locking positions of one arm, and to Figs. 1l, 14:, and

ICO

15, which similarly illustrate the other arm, that the two horizontal entrance portions of the respective slots are outof alinement with each other, thereby preventing the disengagement of either arm with the barrel so long as the two arms are .held in alincment or combination by means of the sectional roll-support connecting their opposite ends.

E designates coacting shoulders on the arms and barrel, which arrest telescopic motion of the former into the latter and which also assist in arresting the telescopic motion of the two sections of the said roll-support. .lf the barrel is made a separate piece from the wallplate, it is provided with riveting-studs a.

Instead of bot-h arms B interlocking with the barrel A only one may be so arranged, as illustrated in Fig. l, the other entering clear,

as shown at H, and being stopped by a shoulp der, as in the other construction.

Each hanger-armB is provided at its free end with a flanged boss towhichis attached one of the sections of the bar that constitutes the roll-support. l preferably employ for this attachmentshort shafts (l, projectinginwardly from said bosses and protruding through apertures in the ends of the roll-support sections, and the wash er-headed screws Y,\\'o1'l\'ed from the inside ofthe sections into the said shafts (l, the entire journaling means being' thus concealed and protected. These parts Y may be made of any suitable form. For instance, they may be of one integral piece and provided with holes 7) for a double-bitted pin screw-driver, as illustrated in Fig'. 6, or they may be made of a separate washer and screw, as illustrated in Fig. 9.

Then the roll-support is formed wholly of metal, as shown in Figs. l to inclusive, it comprises two tubular sections O and P, journaled, as described, to the hanger-arms. The one tubular section,P, constitutes the outer section and is provided with a longitudinally-extending series ofslots S, beyond which is a hole V, and the other tubular section, O, constitutes the inner section designed to telescope into the outer section and provided with a comparati vely long longitudinal end slit forming a spring-tongue Q, bent or buckled upon itself intermediate its ends to 'form a beveled shoulder R, constituting a pawl, and also provided at its free or open end with a plurality of comparatively short slits T to allow for the contraction of that end of the tube for easy insertion into the other tubular section. Then the section O is telescoped into the section P, the pawl lt is sprung into any one of the slots or ratchets S, according to the length of rollsupport desired for the particular roll used, thereby automatically locking the two sections and preventing' the separation of the same until the roll material supported thereby is wholly unwound. To effect the separation, the spring-tongue extends beyond the pawl R and across the hole V, through which of wood, as illustrated in Figs. 7 and 8, in

which event the outer section K is provided with a ratchet-bar N and pin-hole V, and the inner section J is provided with a springtongue L, having a beveled pawl M for engagement with the ratchet-bar. A spring' W,

I encircling a pin U` keeps the locking spring'- tongue adequately pressed into engagement. In both forms or constructions the hole V for the passage of a disengaging pin is equidistant from each end of the support and is inaccessible until the roll is wholly unwound.

As shown in Figs. 10 and 11, the wall-plate is extended below the barrel A, as at F, a distance greater than that from the barrel to the circumference of the hanger-arm flanges Gr, thereby acting as a bumper-plate for the latter and as a friction-plate against which the roll may rub to effect a mild braking action against the unwinding motion and protecting the wall from injury by either the roll or thel flanges. The flanges act as a guard to keep the material of the roll in proper place and as a bumper or striker for the roll-support when there is no roll thereon.

ln practice to assemble the parts the sections of the roll-support are inserted in the ends of the roll and are telescoped and automatically locked together, the ends of the hanger-arms B being also inserted in and inter-locked with the plate-barrel A. The roll is thus locked in place. After the material has been wholly unwound and the pin-hole V exposed the sections of the roll-support may be then unlocked and withdrawn from each other, either or both of the hanger-arms being at the same time withdrmvn from the plate-barrel by swinging the same into register with the outlet portions of the bayonetslots. Itis obvious that if only one of the hanger-arms is provided with the bayonetslot connections both arms may be simultaneously locked in and simultaneously withdrawn from the plate-barrel; but if both are provided with the bayonet-slot connections out of alinement with each other, as before described and illustrated in Figs. l() to 15, inclusive, only one arm at a time can be locked in and withdrawn from the barrel. In this latter event one of the hanger-arms is locked into engagement with the barrel first. The roll is then inserted on its attached section of the support, and the other section and hangerarm is finally inserted in place.
