Our invention relatesto devices employed to render easy and; sure of proper operation ma'nifolding machines in which the paper feed is e'ner d byan electric motor.

In Unite States Patent No. 1,437,949'dated Dec. 5, 1922, is described a'form of operating motor, .which is provided for use with our invention, and reference is made to said patent for a descri tion of the motor, of which the essential point is that when the rotor is prevented from movement, it will feed lengthwise of the stator and shut ed the current.

As in said patent we provide a paper feed drive, a stop to limit the rive to si le revolutions, this stop serving to open an close the circuit thataenergiz'esthemotonp Also as in said atent; we operate the paper stop trip by means 'of a pawl which will pivot out of. controlling position when the motor is started, so that a single de ression will always bring about the feed 0 but one section of paper whether the starting and release manner, and thus operate is machine by hand. v I

In dealing with the motor drive for paper connections.

device is held down by the hand or not.

Our improvements herein deal with the mode of connecting the motor to the paper feed shaft, and securing it to the machine, and also deal with a simple method whereby, should the current supply be stopped, the user may attach a handle, in a ve quick and easy feeding devices of the manifolder type, there has been considerable difliculty attendant upon the use of the machines of the said Letters Patent due to the fact that any inaccuracy in the paper feed shaft developed a tendency of the motor to weave about in its mountings, resulting finally in binding at its connections withthe machine. I

In order to overcome thisv difliculty, we have added an improvement to the former practice as will be noted.

In connection with the shifting from motor drive to hand drive for our machines, past practices required dismounting the motor, and applying a handle in the place of the motor Obviously this has not been satbecause current shut downs are isfactory,

and a certain amount not of long duration,

.' it down,

of skill is requiredto'mo'unt and dismount a motor from any kind of a machine.

In our improvement we have provided for a pro'ection of the paper feed shaft from the ot er side of the machine, and have covservesas a loc to hold-a closed cabinet down over the frame of the machine and also when removed leaves the shaft exposed for insertion of a manual feed handle.

We accomplish the objects of our invention by that certain construction and arrangement of parts to be hereinafter more specifically pointed out and claimed.

.ered this pro'ection with a member which equipped with pin wheels 4 for feeding the paper, the paper storing means, writing table, and method of moving the paper webs being uniform. with known practices, and not being illustrate p A suitable hinging means is provided at one end of the machine for a cabinet 5, which has suitable clearance therein for the motor device, and a hole 6 therein for the feed shaft at the opposite side. The cabinet is swung down so as to entirely cover the maand means are provided for locking chine,

by the same means as plugs up .the

I so

hole 6. Also, through this hole the manual feed handle is inserted.

Mounted on the frame is a motor 7, like that of the patent referred to, which 1s released, as is the pa er feed by a mechanism formin no part- 0 this invention, but generally s own at 8..

The motor drives a gear 9, which retains some of the friction discs 10, while the shaft of this gear is engaged by others of the discs. The shaft 11 (see Figure 2) is provided with a spring 12, and anut 13 for tightening the friction is equipped at its inner end with a barrel 14 for engaging the paper feed shaft. This barrel has the paper feed control cam 15 thereon, and also a grooved collar ortion 16, which engages tongues on the riction discs thereby coupling them with the shaft.

The feed shaft is formed at the ends with slotted portions 17, terminating in holes 18, and ins 19 are set into the ends of the shaft insidg of the slots, said pins forming clutch faces for driving the shaft.

The barrel on the gear shaft is provided with a hole 20 considerably larger than the endof the shaft, so as to permit misalignment or uneven rotation of the shaft without influencing the motor. The barrel has grooves 21 at 180 degrees, for engaging the pin 19, when the barrel is thrust over the shaft. These grooves are also considerably larger than'the pin, so as to drive steadily but permit freedom for uneven rotation of the shaft. In order to prevent dislodgment during shipment and rough handllng, we usually drive a pin 22a through the holes 22 in the barrel, which holes are larger than the pin, but which pin fits snugly in the hole 18 m the end of the groove in the feed shaft.

By-this means the gear of the motor drives the feed shaft directly, but full'allowance is made for misalignment or unevenness of motion, which is a very important factor in these devices, and seriously affected the possibility of marketing them until the novel arrangement of parts now described was discovered.

The motor can be very tightly aflixed to the frame of the machine in view of the driving connection noted, and to this end a wide metal band 23 is provided which passes around the motor and is screwed to the side frames of the machine thereby holding the motor immovable in place.

It has been noted that the feed shaft extends out through the other side frame, from the one on which the motor is mounted. This end of the shaft is the same as theend connected tothe motor thus permitting a reversible shaft.

A plug 24 (Figure 3) is provided which 1s mounted over the end of the shaft, and'has a flange 25 which lies outside of the enclosing cabinet, when the same is shut down. The

plug has grooves 26 whichengage the clutch pin on the feed shaft, and has also a pair of in the end 0 the groove in the feed shaft.

In order to place the plug on the shaft, it is thrust throu h the hole in the cabinet, and pushed througi until it engages the shaft fully'with the spring pins in place in the holes. It is then locked on the shaft and the cabinet cannot be removed, thus preventing tampering with the machine.

The manual feed handle has a similar barrel 28 to the plug just described, and also the handle portion 29. In the case of both the plug and the handle barrel, there is a key slot formed therein as at 30, which permits the insertion of a key to force the spring plungeris outwardly, thus freeing the handle or p ug.

When the electric current is 03, the operator simply uses the key to take out the plug, replaces it with the handle, and then releases the paper feed from the motor side of the device and revolves the feed shaft by means of the handle.

Thus in our mechanism we provide adequately for the two problems ofpractical importance, still left in the electrically operated manifolder.

\Vhen the current is off a very quick change puts a manual operating handle in place. When the feed shaft gets out of line, or revolves unevenly, or the machine frame becomes slightly distorted, still the motor will operate without tending to become loose in its mounting, and a very firm method of securing it to the machine frame can be 7 adopted.

Having thus described our invention, what we claim as new and desire to secure by Letters Patent, is

In an electrically driven manifolding machine having a feed shaft therein and a motor, a loose driving connection between the motor and the feed shaft, said connection comprising pin forming projections'adjacent the end of the feed shaft and a socketed element driven bythe motor and arranged with notches to loosely engage said projections, said socket loosely engaging over said shaft. and a second pin loosely mounted in one of the said parts and tightly engaging in the other for additionally securing the parts together against removal.
