DISPLAY APPARATUS.

To all whom it may concern:

Be it known that I, EVERETT M. DOUGHERTY, a citizen of the United States, residing at Escanaba, in the county of Delta and State of Michigan, have invented certain new and useful Improvements in Display Apparatus, of which the following is a specification.

The device which is the subject of the present invention is designed more particularly for supporting and displaying rugs and similar articles, and it has for its object to provide a structure which permits the storage and display of the articles in a very small space.

A further object of the invention is to provide a horizontally swinging and vertically adjustable display arm, together with novel means for operating the same.

The invention also has for its object to provide a display device which is simple in construction, and which can be easily operated.

Other objects and advantages of the invention will be apparent from the detailed description appearing hereinafter, and in order that the invention may be better understood, reference is had to the accompanying drawings, in which- Figure 1 is a side elevation of the device, the article supported thereby being shown in dotted lines. Fig. 2 is an elevation showing the display arm in lowered position. Fig. 3 is a cross section of the pivoted end of the display arm. Fig. 4 is a horizontal section on the line el- L of Fig. 3. Fig. 5 is a cross section of the display arm showing the method of fastening the article thereto. Fig. 6 is a plan View of the hoisting gear, partly broken away. Fig. 7 is a side elevation of said gear, partly broken away.

Referring specifically to the drawings, 10 denotes the supporting arm of the rug or other article to be displayed. The arm is horizontally disposed and swings horizon tally, and is also adjustable vertically as will be presently described. A diagonal brace 11 is connected at its outer end to the arm near the extremity thereof, a pivotal connection 12 being provided. The brace is free to swing in a vertical plane, it being pivoted at 13 to a support comprising a base 14 having upstanding ears 15 between which the inner end of the brace is received and through which the pivot passes. The support is" pivoted at 16 to a horizontally Specification of Letters Patent.

positioned plate 17 to swing in a horizontal plane, said plate being carried by brackets 18 rigidly secured to the wall or other support 19. The pivot 16 is a bolt which passes vertically through the base 14 and the plate 17. It will therefore be evident that the brace is free to swing vertically as well as horizontally.

On the wall 19, a suitable distance above the brackets 18 is rigidly mounted a bracket comprising an angular plate having horizontal and

vertical portions

20 and 21, respectively, the latter being secured to the wall in any suitable manner. In the outer edge of the part 20 is a slot 22 which is flared at its outer end and is enlarged at its inner end to form a circular hole 23. From the bottom of the arm 10, at its inner end, depends a flat stem 24 having adjacent to the arm a cylindrical portion 25 of a diameter to fit loosely in the hole 23. The thickness of the stem is such that it can pass through the slot. The hole 23 is in axial alinement with the pivot 16, so that when the part 25 is seated therein, the arm 10 can be swung in a horizontal plane, the said part 25 serving as the pivot of the arm. Upon disengaging the part 25 from the hole 23 the arm can be lowered by the mechanism to be presently described. The

parts

24 and 25 are formed integral with a plate 26 which is fastened in any suitable manner to the bottom of the arm 10.

The brackets 18 support a horizontal shaft 27 on which are mounted

winding drums

28 and 29, respectively, of different diameters. On the drum 28 is wound a hoisting line 30 which passes upwardly and over a pulley 31 mounted on the wall 19 a short distance above the plate 20, and thence passes forwardly and is made fast to the rear end of the arm 10. On the drum 29 is wound a hoisting line 32 which passes upwardly and over a pulley 33 mounted on the wall 19 adjacent to the pulley 31, and thence passes forwardly and is made fast to the arm 10 near its outer end. The connection between the last-mentioned line and the arm may be made by means of the pivot 12. The plate 20 has openings through which the lines pass to the pulleys.

The

drums

28 and 29 are loose on the shaft 27 so that they may he slid lengthwise squared portion 34 to t a correspondingly shaped portion of the bore of the drum. It will be noted that the drums have different diameters, the drum 28 being the largest, and this drum also has an enlarged portion 35. The purpose of this will be presently made clear.

The following means are provided for operating the drums 28 and 29: On the shaft 27 is made fast a bevel gear 36 which is in mesh with a similar gear 37 carried by a shaft 38 journaled in the depending ears 39 of a plate 40 secured to the bottom of the plate 17. The shaft 38 is fitted with a crank handle 41, and through the ears 39 passes a locking device for the shaft, said device comprising a sliding pin 42 adapted to be placed in the path of the crank handle to prevent the same from turning in a direction to unwind the

lines

30 and 32. To release the shaft it is necessary only to slide the pin rearw'ardly until the crank handle can clear the same. On the pin are stops 43 which are located on opposite sides of one of the ears 39 and are adapted to engage the same and thus determine the locking and release positions of the pins To one of the brackets 16 is secured a spring finger 44 which projects toward the shaft 27 a suflicient distance so that it may be slipped behind a flange 45 on the drum 29 when said drum and the drum 28 are slid along the shaft to clear the squared portion 34 of the shaft. The two drums are connected so that they will turn together; or they may be formed integral with each other.

To the extremity of the arm 10' is pivoted a prop or foot 46 which is in two sections which are adjustably connected -by a pin and slot connection. The outer end vof the arm also carries an extension 47 In use, the rug 48 or other article to be 7 displayed is hung on the arm 10, as well as on the extension 47 if necessary. Clips or other suitable fastening devices 49 are provided for securing the article in position on the arm. Assuming the arm to be in lowered position, it is elevated by turning the crank handle 41 the latter being first unlockedby sliding the pin 42 out of the way. The crank handle, through the

gears

36 and 37 rotates the shaft 27 and turns the drums to wind the

lines

30 and 32 thereon. The inner end of the arm is elevated by the line 30 and the outer end by the line 32. The arm is thus elevated until the stem 24 comes in line with the slot 22, at which time the line 30 is starting to wind on the enf larged portion 35 of the drum 28, thus causing the rear end of the arm to tilt upwardly so as to allow the part 25 to pass above the slot 22 and the stem 24 to enter the latter and pass to the hole 23. The arm is then swung slightly either way and the two lines are slackened, whereupon the which, as already described, is in axial alinement with the pivot of the arm. To lower the arm 10, the part 25 is withdrawn from the hole 23, which is done by turning the crank handle in a direction to wind the lines. The line 30 being still on the enlarged portion 35 of the drum 28, the part is lifted out of the hole, whereupon the slack in the line 32 allows the stem 24 to slide out of the slot 22. In this operation the line 30 is under tension. When the part 25 was inserted into the hole 23 both lines became slack. The arm 10 now being released from the plate 20, it can be lowered, by allowing the lines to unwind, until the foot 46 touches the floor. The foot will be adjusted so that the arm is held by the same horizontally the desired distance from the floor. The brace 11 is a channel bar and the arm seats in the channel when it is in lowered position. The arm may also be a channel bar.

The purpose of slidably mounting the

drums

28 and 29 on the shaft 27 is to render possible the employment of a plurality of display arms, a set of winding drums being provided for each arm. The drums of the arms not in use will be thrown out of gear and held in this position by the finger 44 as already described.

The narrow space occupied by the de vice permits the storage of many rugs and other articles in a small space, and the horizontal swing of the arm 10 makes the display of the articles very easy. The drums are of such relative diameters as the length of the display arm and the height may necessitate for the raising of the arm to horizontal position. I

The device herein described is simple in structure and therefore can be cheaply made, and it effectually serves the purpose for which it is designed. It may be made of any suitable material and in different .sizes to serve the storing and display of different articles.

The preferred embodiment of the invention has been shown, but it will be evident that various minor changes in the structural details may be resorted to without a departure from the spirit and scope of the invention.

I claim:

1. A display device comprising a support having a slotted edge, said slot terminating in a circular aperture, a display arm having a pivot adapted to seat in the aperture, said pivot having a depe'nding guide stem adapted to pass through the slot, hoisting lines connected respectively to the inner and outer portions of the arm, drums on which the lines are wound, said drums having different diameters, and the drum on which the line which is connected to the inner portion of the arm is wound having the largest diameter, and said drum having an enlarged portion, and means for rotating the drums.

2. A display device comprising a support, a horizontal arm loosely carried thereby, means for disengaging the arm from the support and for raising and lowering the arm, and a prop carried by the arm for sup porting it in lowered position.
