It is an object of the present invention to provide a simplified device which will clamp and mount a curtain rod and which may be manipulated without the necessity of tools for the purpose.
A further object of the invention is to provide a device of this character which is adjustable to clamp rods or" different sizes and Which is also adjustable to space the vrod a predetermined selected distance from the wall on which the device is mounted.
A further object of the invention is to provide a device of this kind which employs a single actuating member for moving and adjusting the rod gripping means and which actuator may function as a locking means for the grippers when moved into their gripping position.
With these and other objects in view, the invention generally embodies a mounting device incorporating a mounting bar having a longitudinal slot therein, a carriage slidably mounted on said mounting bar having a fixed and a movable jaw disposed beyond an end of said bar for clamping a curtain rod, van actuator, means traversing said slot rotatably mounting said actuator adjacent to said mounting bar and carriage, and forming a means of connecting said actuator and carriage, means operatively connecting between said actuator and carriage for moving said movable jaW relatively to the xed jaw to and from a clamping position when -said actuator is -rotated and means for locking said jaws in rod clampingV position. Preferably, the actuator performs the latter function as well and the structure includesv means coacting between said actuator and said bar for locking said jaws when in rod clamping position.
The invention will be more clearly understood by refer ence to the following detailed speciiication taken in conjunction with the accompanying drawings.

FIGURE 8 is a fragmentary longitudinal section taken through a still further alternative form of the invention.
Referring to the drawings, and tirst of all to FIGURES l1 to 4, A indicates the mounting device as a whole which is made up ofa mounting bar B, a slidable carriage C and an actuator D. The mounting bar is preferably of the bracket type having an otset portion 1d disposed substantially at right angles to the bar proper and orificed as at 11 for mounting on a wall, window frame or the like. The bar B is formed with a longitudinally extend'- ing slot 12 for the purpose of slidably mounting thereon the carriage C.
The carriage C is made up of two elements, namely,-
the slide bar 13 and the slide bar 14, the former being provided with the odset portion 15 adjacent its outer end to form a gripping jaw, whereas the slide bar 14 is offset adjacent its outer free end to form the gripping jaw 16. The slide bar 13 is `formed with depending flanges 17 extending longitudinally along its side edges over a substantial extent of its length to form a guideway 18 for slidably receiving the slide -bar 14.
The slide bar 14 is provided with a longitudinally eX- tending slot 19 disposed to register with slot 12 in mounting bar B when'said slide is superimposed thereon in its assembled state and a part of the material removed to form slot 19 is struck in the form of a lug or tongue 20 which depends from this slide bar and is adapted Yto traverse the slot 12 in the mounting bar B for operative connection with the actuator D. Preferably, the'slot 19 in the slide bar 14 is of the same width as the slot 12 in the bar B, and the lug or tongue 20, therefore, may act as a guide within slot 12 during the movement of the slide 14 relatively to the bar B.
The assembled carriage C made up of the relatively movable slides 13 and 14 is superimposed on the upper Vface 21 of the bar B with the tongue 2t) projecting through the slot 12 in the bar B and, through a suitable oritice 22 in the slide bar 13, a suitable pin rivet or the like 23 is caused to pass through the orifice 22, slot 19 in slide bar 14 and slot 12 in bar B and to pass through an oritice 24 in the actuator D as to rotatably mount the actuator adjacent to the other face of the mounting bar B. This also serves to connect the slides 13 and 14 together to form the carriage C, and it will be understood that the carriage C together with the actuator D may be caused bodily to slide on the bar B to the extent of the length of the longitudinal slot 12 therein. Consequently, it will be understood that when the carriage is not locked to the bar B the carriage may be shifted so as to position the opposed gripping jaws 15 and 16 thereof directly adjacent to the outer free end 25 of the bar B, at which point the lug or tongue 20 will be disposed directly adjacent the opposite end of the longitudinal slot 12, or said carriage may be shifted axially of bar B to dispose the jaws a greater distance out therefrom. Accordingly, therefore, the mounting device provides for adjusting the location of the jaws', and a rod which they mayhold, outwardly from the wall, window frame, etc. on which the mounting bar is secured so that the desired spacing of the rod from said wall, window frame, etc. may be selected as required within the limits of the sliding adjustment.
The actuating member D is provided with a suitable curved cam track preferably in the form of a slot 26 which is slottedeccentric to the pivotal orifice 24 thereof and so arranged that the terminal end thereof 27 is spaced further from the oritice 24 than the terminal end 27a and in the full open position of the jaws 15 and 16 the terminal end 27 of slot 26 is located just to one side of slot 12 in the bar B as to cause a portion of slot 26 at this end thereof to intersect slot 12 of bar B so that the tongue or lug 20, traversing this latter slot, will project into slot 26. Consequently, upon rotation of the actuator D in a clockwise direction, i.e., direction of the arrow Shown in FIGURE 1, the cam track formed by slot 26 in this turning movement of actuator D will through the medium of lug Ztl cause slide 14 of the carriage C to slide axially and move jaw 16 towards jaw 15 and will space the jaws and 16 a varied distance apart depending upon the extent to which the actuator is rotated. Consequently, the jaws may in this manner be caused to grip a curtain rod :in the manner illustrated in FEGURE 2; thus, if the slides of carriage C are then locked in this clamping position lthe rod will be securely held as desired. Suitable locking means therefore forms a part of the invention to 4achieve this purpose.
The locking of the slide bars 13 and 14 of carriage C in the clamping position is preferably achieved, accord- .ingto the invention, by the actuator D and effected when `the actuator has caused the jaws 15 and 16 to engage and clamp a rod. In this instance, the actuator is provided with the depending actuating fingers 23 preferably dis- .posed diametrically opposite one another, and the body of the actuator is provided with raised portions projecting Vabove the plane of the upper face thereof and which may take the form of the raised shoulders or ribs 29, the upper face of the actuator body D between the shoulders 29 being of a width as to straddle the width of the bar B, thereby disposing the shoulders or ribs 29 outside the marginal side edges of bar B when the jaws are in their full open position and the carriage is freely slidable on bar B. When, however, the actuator D is rotated clockwise as to cause the jaw 16 to move toward the jaw 15, the 'shoulders or ribs 29 move into bearing engagement with the lower surface of bar B, thereby exerting an axial pull on the pin 23 as to cause the relatively sliding Vparts 13 and 14 of the carriage to be locked together and locked to the bar B, thus making this unit a rigid one. Accordingly, simultaneously with the movement of jaw 16 into clamping position, locking of the movable parts of the carriage C to the bar B occurs.
It lshould be clear, therefore, that when the actuator D is in the position shown in FIGURE 3, i.e., the unlocked position, the carriage is freely slidable on bar B to the extent of the longitudinal slot 12 as to position the open gripping jaws outwardly of the free end 25 of bar B to the required extent and upon then rotating the actuator D `in a clockwise direction the jaw 16 is caused to move toward jaw 15 to clamp a curtain rod firmly therebetween, and the engagement of ribs or shoulders 29 with the bottom face of bar B in this operation will then cause locking of the parts as to form a rigid device. In -both FIGURES 2 and 3, as will be noted from the location of the tongue relatively to the left hand end of slot 12, the jaws are disposed in an outwardly adjusted position relatively to the end of the bar B.
Referring to the alternative form of construction shown 4in FIGURE 5, the action is of similar character though the relative movement between the jaws of the device is opposite. In this construction, the bar B is substantially identical in construction to that shown in FIGURES 1 to '3. However, the carriage C1 is of slightly different construction, wherein the flanged slide bar 30 is formed with an outer free end offset to form the inner jaw 31, said 'offset portion being slotted as at 32 to permit the slide bar 33 to pass therethrough in sliding relation. The outer end of slide bar 33 is provided with a longitudinal slot 35 and'forrned with a depending lug or tongue 36 similar to the corresponding construction of slide bar 14 in FIG- URES 1 to 3, and the device is assembled in a similar manner and secured by the pin or rivet 37. The pin secures the actuator D1 rotatably in a similar manner adjacent to the under face of bar B. VThe curved cam track ork slot 38 of actuator D1, however, is substantially reversed Vin relation to kthe orifice 39 thereof to the arrangement shown in FIGURE 1, and in this case with the carriage in free sliding relation to bar B and the jaws opened to their maximum extent the terminal end 40 of cam track 38 is disposed so that lan adjacent portion thereof intersects the longitudinal slot 12 of bar B. Therefore, when the actuator D is rotated by fingers 42 in a .clockwise direction, as indicated by the arrow, the cam track 4t? acting on lug 36 of slide bar 33 will cause the slide bar to move inwardly in the direction of the yarrow shown adjacent jaw 34, thus to cause jaw 34 to move in a direction towards jaw 31 to effect the clamping action of the curtain rod. Similarly, the ribs or shoulders 43 of actuator D1 will engage the lower face of bar B and cause locking of the carriage in the manner described in respect to FIGURES 1 to 3. Thus, clamping of the jaws in both cases is effected by causing said jaws to move relatively to one another under actuation of the actuator D or D1.
Locking of the carriage to the bar B may be effected by the actuator in a different manner from that described in the previously mentioned figures and this is illustrated in FIGURE 6, wherein the bar B1 is formed with marginal ribs 44 that project outwardly below the plane of the lower face of the bar, whereas the actuator D2 is simply a planar member having the depending fingers 45. The actuator here shown is of greater length than width and in the unlocked position (FIGURE 6), where it is axially aligned with bar B1, its width fits within the span of the ribs 44, but as soon as the actuator is rotated cross-wise of bar B1, to cause the jaws to effect their clamping action, the engagement of the upper planar face of actuator D2 with the ribs 44 will naturally cause an axial pull on the pin 37 as to effect a locking of the parts rigidly together in a similar manner to the action effected in FIGURES 1 to 5.
In FIGURE 8 a further alternative is illustrated similar in action to the construction shown in FIGURES 1 to 5 but wherein mounting bar B is disposed between the slide `bars 13 and 14 which together form the carriage C. The
Vaction in this case is the same except that locking is effected by co-action between the actuator D and the slide bar 14. Accordingly, it will be apparent that the locking action is achieved in respect of the various forms of construction by co-action between said actuator and one of the bars B, B1 or 14.
It will be apparent from the foregoing, therefore, that by a simple variable arrangement of carriage and mounting bar, a curtain rod mounting device is readily provided which is easy of mounting, readily adjustable and will effect firm clamping and unclamping of curtain rods in a simple manner without the necessity of tools for the purpose. As shown, the combination may be varied with different arrangement of the slide bars of the carriage such as illustrated and obviously, of course, the arrangement of FIGURE l could be reversed as to dispose the actuator above the mounting bar and the slides below it. It will also be understood, of course, that the device can be constructed so that the slide bars are adjustable relatively to one another for clamping purposes without providing for the sliding adjustment of the bars for spacing the jaws in selected spaced apart relation from the end of the mounting bar, in which case it would only be necessary to so slot the movable slide bar as to cause its movement relatively to the other slide bar.
