UNITED STATES JOHN W. GI-IEEN, F IlOS ANGELES, CALIFORNIA.

MACHINE FOR HANDLING BUGS.

Application filed October 13, 1920. Serial No. 416,738.

To all whom it may concern. I

Be it known that I, JOHN WV. GHEEN, a citizen of the United States of America, residing in the city of Los Angeles, county of Los Angeles, and State of California, have invented a new and useful Machine for Handling Rugs.

The objects of my invention are: F 'irst to provide a machine having a carriage to automatically transfer rugs, carpets or other like articles from one pile to another in order that the surface of the top articles may be exhibited. Second-to make a machine that will slowly reverse its motion at the end of each stroke. Thirdto provide a collapsible rug frame that may be stored in a small space when not in use.

I attain these objects by means of the mechanism illustrated in the accompanying drawings Fig. 1 is a side view of a machine for displaying rugs, carpets and other like articles and embodying the principles of my invention.

Fig. 2 is an end view of the same.

Fig. 3 is an enlarged top view of the switch reversing mechanism.

Fig. 10 is a reduced top plan of the collapsible rug frame.- a

Fig. 11 is an end view of the same.

Fig. 12 shows the rug frame folded.

Fig. 13 shows the rug frame braces.

The frame hangers 1 and 2 are suspended from the ceiling 4, the

track rails

5 and 6 extending the fulllength of the two rug piles and are shown integral but may be secured to the hanger by suitable means. The spreader braces 7, 8, 9 and 10 also act as stops. The braces 11 and 12 form journals for the sheaves 13 and 14. The bracesv carriage moving power and its control, as

shown in Fig. 1, 2, 5,6, 7 and 8. The

operating cylinder 23 is secured to the ceiling 4 by the brackets 24 -and 25. On the end of the cylinder 23 are the heads 26 and 27 and the stuffing boxes 28 and 29. The p ston 30 is secured to the piston rod 31. A fork and pin on one end of the piston rod 31 carry the sheave 32, and the other end of the rod 31 is held in a similar manner by the sheave 33. The pin 34 is extended to form a journal for the sheave 35. The cable 22 is connected at one end to the brace bar 20, passing around the

sheaves

33, 13 and 18. The other end is secured to one end of the rack bar 36. The cable 22 at one end is secured to the brace bar 19 passing around the sheaves 32, 14 and l7 the other end is secured to the free end of the rock bar 36. The pressure inlet pipe" 37 and an exhaust pipe 38 are connected to the throttling valve 39. A port pipe 40 leads to one end of the cylinder 23 and asimilar pipe 41 leads to the other end so thatwhen the pressure is admitted to one end of the cylinder 23, the other end of the cylinder is exhausting. The valve 39 is controlled by the valve handle 42 which is slotted at its outer end to receive the shifting arm 43, in Fig. 2. c

The following refers to the dash-pot which regulates the motion of the carriage at each end of the stroke, see Fig. 1, Fig. 2, Fig. 5 and Fig. 6. The cylinder 44 is secured to the ceiling4 by the'brackets 45 and 46. The

heads

47 and 48 are. secured to each end of the cylinder 44 and are pro- I 57 and a similar spring 60 separates 1 the arms 55 and 58. The by-pass 61 is controlled by the by-pass valve 62, in Fig. '2. The port openings 63 and 64 are positioned at either endof the cylinder 44.. The rocker. rod 65; is journaled in the hanger 66 WhlCh is secured to the ceiling 4 and to'the bracket 67 on track 6, and the rocker rod 68 is similarly secured. A crank 69 on the lower braces as at 91 in Fig. 7. 92 is secured to bar support 86 by the headend of the rod 65 projects into horizontal alignment with the stop on the bar 36. The bar 67 having a crank 71 for contact with the pin 72. The upper cranks 73 of the rocker rod 65 engages with the shifting rod 53 on one end and the crank 74 with the other. When the pin 72 is brought into contact with the crank 69, the rod 65 moves the crank 73, and the shifting rod and the arm 55 acts upon spring 60, the fluid if gradually forced from one side of the piston 44 through the port 64, the by pass 61 and port 63 to the other side of the piston 44, valve 62 controlling the speed of the piston 44. This. will retard and finally stop the movement of the carriage through the arm 43, in Fig. 2. The handle 42 and the valve 75 so change the main cylinder port openings that the motion of the carriage will be reversed.

The following refers to the upper carriage frame as shown in Figs. 1 and 2 and consist of four hollow

vertical posts

76, 77 and 78, and one not shown. The tops of these posts are journaled to the sheaves 79, 80

vand 81 and are hung on the

tracks

5 and 6. The frame is made rigid by the brace bars 82, 83, 84 and 85, and four others not shown. The rack bar 36 is carried by the bar supports 86 and 87 extending clownwardly from this bar on the crank hangers 88, 89 and 90, and another not shown. The bar supports 86 and 87 are secured to the A rocking T-bar ed'pin 93. The sliding stops 94 and 95 are operated by the

pins

96 and 97 in the slots of the T-bar 92. The following has reference to the lower carriage lifting mechanism in Figs. 1, 2, 7 and 8. As the piston 30 through the cable moves the bar 36, revolving the

gears

98 and 99; which are attached to the

shafts

100 and 101 and the cranks 102 and. 103, and to another pair of cranks not shown. These cranks are attached to collars which slide upon the

lifting reversing rods

105, 106 and 107, and another reversing rod not shown; these rods have

collars

108, 109 and 110 upon the upper ends and when the cranks lift rods the lower carriage frame is raised. In the continued movement of the bar 36 the stop 111 strikes the lifting stop 94. This causes the carriage to move. Then the T-bar 92 strikes spreader brace 8 the carriage stops and the sliding stop 93 is raised. The bar 36 continues its travel and the

gears

98 and 99 are revolved and cranks 102 and 103 descend upon the springs 111, 112 and 113, and another not shown, and press upon the lower collars attached to the

shafts

105, 106 and 107, and another not shown, and

lower the shifting frame. The springs 112,

113 and 114, and another not shown, accornmodate the changing heights of the rug pile. The lifting frame consists of the rods 115, 116 and 117 and another not shown and is held by the

braces

118 and 119, and two others not shown. The rods 115, 116, and 117, and the one not shown, on the upper end telescope into the

carriage frame rods

74, 75 and 76, and another not shown. The electro magnets 120, 121, 122, and another not shown, are operated by the double switch shown in Fig. 4 mounted. upon the bar 36.

The switch lever 123 is operated by being brought into contact with the spreader bars 8 and 10.

The following has reference to the auto matic provision for reversing the electric current when the bottom of the pile is reached, referring principally to Figs. 3 and 4. The upper end of the rod 127 is bent to form the dog 124. The lever 125 is pivoted to the upper carriage frame. "When the last rug in the pile has been reached, the dog 124 engages with one end of the pivoted lever 125, the other end of the pivoted lever 125 is connected to one end of the link 128, the other end of the link 128 a pin to which is secured one end of the spring 151. This pin connects one end of the rocking lever 156, the other end is loosely mounted on the steel shaft129. The bracket 130 which is secured to the brace 84 forms a bearing for the stub shaft 129. To the outer end of the stub shaft is secured on one end of the crank 132. The spring 133 is connected to the crank 132 and to the pin 131 in the bracket 130. The crank 134 is secured to the stub shaft and to one end of the switch link 137, operating

switch knives

137, 138, 139, and 140.

The operation of this mechanism is as follows: The dog 124 strikes the lever 125, the link 128 move the rocking lever 156, the hub of which engages with the hub of the crank 134 moving this toward B, carrying the crank 132 toward the position D, after passing the central position between C and D the spring 133 completes the stroke. Vhen the dog 124 moves upward, the lever 125 drops and the spring 151 changes the position of the rocking lever 150 from E to F. And G and H indicate the full throw of the rocking lever 150, A and B the extreme position of the lever 134, and C and D the extreme of lever 132. The switch is enclosed in a cover 152. The switch-board is secured to the frame brace by the

straps

153 and 154.

The following has reference to the rug frames as shown in Figs. 1, 2, 10, 11, 12 and 13. The rugs to be exhibited are laid upon metal frames and placed in a pilev beneath the carriage. The rug frame consists of the metal bands of suitable size. The side bars are pivotally connected to the cross bars 157 and 158 so as to fold as shown in Fig. 12. The braces 159 are held in position as shownin Fig. 10 by means of screws, the rug frame is shown folded in Fig. 13.

The following has reference to the elec tric magnets for lifting the rug frames shown in Figs. 1, 2, 3, 4 and 9. The electric cable 160 is attached tothe ceiling passing over the brace 20 and the sheave 35 and a groove in the double sheave 13 and a groove in the double sheave 18 and to the switch box, where itis connected to the terminals 161, 162, 163 and 164. A second cable is connected on one end of the terminals 147 and 148 and passing around the electro magnets 120, 121, 122 and to the terminals 143 and 144. In operation the switch handle 137 strikes the brace rod'8 and the contact 162, 164, 168 and 169 is automatically made. As there is a contact at 144, 145, 148 and 149 the current flows around the electro magnets 120, 121, 122 and 222 securing a rug frameas the carriage travels toward the spreader bar 10, the switch handle 127 strikes the spreader bar 10 and the contact 162, 164, 168 and 169 is automatically broken and the contact 160, 167, 161 and 165 is formed as the contact 144,145, 148 and 149 is open the rug is deposited.
