and 47 from the pulley 49. Upon moving the shift lever 90 in the opposite direction the reverse operation will take place.

Referring now to the construction of the devices for operating the carpet ejector mechanism and reversing the same. 92 designates a shaft that is driven by the bevel gear 79 which carries a bevel gear 93 at its lower end which meshes with a bevel gear 94 that drives the cross shaft 95 which carries the bevel gear 95 at its opposite end which operates the gear 96, shaft 97, gears 98 and J9, shaft 100, gear 101, gears 102, and 103. The gears 107 and 108 mesh with the rack bars 104 and 105, the teeth 106 of which are located on their inner edges, as shown. These bars are connected by the piece 104. It will be seen that by means of the shift lever 81 the direction of rotation of the pinions 107 and 108 which mesh with these racks may be reversed.

After the carpet has been wrapped with paper from the roll 20 the completed roll isthen ready to be removed from the machine, which is accomplished as follows: The op erator moves the shift rod 81 which, through the lever 81 moves the clutch block 67 so that the projection 57 on the gear 42 enters the recess 2 whereby the shaft 92 is operated. The gears 10'? and 108 will now be operated through the mechanism just described causing the two rack bars 104 and to move forward towards the right hand. The part 32 will engage the end of the rolled anl wrapped carpet causing it to be moved along on the wrapping shaft 29 until it reaches the end of this shaft. At this point in the operations the shoulder part 111 on the end of the bar 104 will engage the slidablc memher which is connected through the rod 110 to the clutch. shift lever 81 and moves one of the clutch members (37 or 68, into a neutral or inoperative or midposition, thus stopping the mitward movement of the rack bars 104 and 105. The roll of wrapped carpet is now removed from the The rack bars are now returi'lel to their original position when an operator moves the rod 81', sriilt lever fill. clutcl member 67 and 68 so as to cause the gears 10? and 108 to rotate in the opposite direction whereby the rack bars will be returned to their original posit-ion.

Referring now to the construction shown in Fig. 3 which is for the purpose of placing a pair of rollers, under pressure, in engagement with the roll of carpet while it is being wrapped with the strip of paper 27, as it unwinds from the roll 20. 113 and 11 1 designates two prcsser rollers, which are slidably mounted on the members 115 and 116 which carries the pivots 117. The members 115 and 116 rest upon the base pieces 118 and 119, which are secured to the uprights 2 and 3. See Fig. 2. Located within each of the slidable members 115 and 116 is a coiled expansible spring 120 for normally moving the presser rollers forward against the carpet roll 28. For retracting these presser rollers each of the slidable members 115 and 116 are formed on their lower edges with a rack 115 and 116 which is engaged by the pawls 121 and 122 that are pivotally connected to the post 123. Leaf springs 124: normally operate to elevate the pawls and retain them in engagement with the racks. The post 123 is slidably mounted in the main frame to which the guide pieces 125 are secured. This post is movable up and down by means of the lever 126 which is pivot-ally connected to the upright 3 at 127. It is formed with a slot 128 which receives a pin 129 on the post 123 whereby when the lever 126 is operated and moved into the dotted position as indicated by the arrow 130, the presser rollers 113 and 11 1 through the pawl and ratchet construction are moved away from the roll ofcarpet 28. This lever is operated just prior to the removal of the wrapped roll of carpet from the machine.

The shafts of the prcsser rollers are mounted inthe bearings 131 at their outer ends, only one of which is shown in Fig. 1.

it should be stated that in order to facilitate the removal of the rolled or wrapped carpet the part 30 which supports the outer end of the shaft 29 must be temporarily removed. This is accomplished as follows: 131 and 132 designate two levers that are pivotally supported on the two studs 133 and 13 1 which are secured in the fixed part 135 of the frame. Formed integrally with the two levers are the gears 136 and 137, which mesh with each other, as shown. Each lever is formed with a semi-circular recess 131' and 132' which match to form a bearing for the outer end of the shaft 29 when the levers are in the closed positions shown. Pivotally attached to the lever 131 is a latch 136 at the point 137. 138 designates a depending part of the latch which retains the levers in a closed position. A spring 139 normally retains the latch in its locking position. 14-0 is a fixed stud in the frame 135 for the purpose of entering matching recesses in the levers for affording additional support for the lovers and shaft 29. lVhen a roll of carpet is to be removed the latch 136 is released and the levers moved to the dotted or open line positions a sufficient distance to permit the roll of carpet to pass between the same. After the carpet has been removed by the pusher bars 105 and be moved through the gear connections 136 and 137 into the dotted line positions.
