POWER-DRIVE POR canoni]iivcfiv'iiiciiiiiiis.y

To all whom t mag/concern y f l 'f Be it known that I, `FREDERICK Gr. JAHN, a citizen of the UnitedStates, andvv resident of Brooklyn, in the county of'Kings and State of New York, have inventedcertain new and useful Improvements in Power-Drives for CancelingeMachines, of which thefollowing is` a specification.

Thisinvention relates to canceling inachines. The ordinary canceling machine `in use, operates upon the'planof `feeding let` ters, checks, cards, or the like, from loose groups or packages held iny thel right .-hand, standing vertically on edge,- the `feeding mechanism snatching the cards or sheetsfoff the group individually with great rapidity,- and nafairly uniform procession or series, although the uniformity fisnot by any means absolute in the sensethat'there is]v anv even spacebetweenv the sheets Orfcards fed in such--` procession. These machines; are oper-k ated bypower wherever electricity is avail-y able, but obviously since the demands of the'.

machine can not waitfor a supply of` ower during periods -thatthe same is cut o it is] necessary to have a hand operation ofthe machine. Thus'the machines are preferably constructed with both hand operating means and power Operating means, and the same must necessarily `be quickly changed y fromv one to the other.

In my prior United States Patentv No. 856,845 a canceling machine is illustrated having these general standard features of construction, 'such as a hand wheelfon an inclined axis adapted to be spun by the left hand while a package of letters isbeingheld l against the feeding `wheels by the right hand. vThis patent also illustratesy the'general `character of the feeding wheel, andthe train of gearing by, which all the rotating parts yare interconnected. It will ybe ob-y served that a large number of gearsare used, and it is practically importantv thatthesegearsbe all immersed in an oil pan, and y that the oil pan lbe lwithout any 'such openf ings or bearings extending through its Walls asmight let the Oil. escape after Sachbear-v ings had become worn. Also it will be observed that'the feeding disksare necessarily f Specification of Letters Patent i ,y Patented N0V 3 1914. i Application med October 23, 1912. serial iro. 727,382. i f

located quite close to the surface of the table since checksand letters aref of a spe-` cial heightwhich will not bey changed, so i that the ycharacter of themacliine must besuited to this work. #In other words, the

more than half the height of the average 'mailymatter or bank note. These various conditions, which must be practically complied witli, have made it amatt'er of great difficulty to drive thefmachine by power.`

Constructions 'embodying the invention will vof course include the usual large feed rubber l, and the usual small feed rubber 2, as these feeding wheels are termed in the art, and which arei'apidly rotating friction disks on vertical axes slightly elevated above the surface of the canceling table. yThe small feed rubber has an upwardly extendsoy ing hub 3, which is smoothly polished, and

whose'purpose is to furnish a sort of a support for the `upper portions of a group of letters or the like being pressed over toward this roll by the right hand. Both of these `rollers are positively driven 'and are intergeared by gears 5 below the table which are iminersedwin the oil pan under the table which is shown, for example, in my' prior patent labove referredto. The usual hand "drive is likewise*illustrated Lin this "prior patent, andthese' features 'arev not changed by thek present inifcntion and' are' therefore not shown.

As'ameans of power operation however,

the small feed rubber 2 is positively driven by a connection above the table and below the frictional periphery ofthe roll, and

of the matter to be canceled, and which isl guided in bearings 8 so as to mesh with a worm gear 9 on the shaft 10 carrying the l small feed rubber 2. The horizontally eX tending spindle will of course rotate at a high rate of speed, and is only well adapted to be driven at such a speedby a direct drive or through a belt from a high speed power source. Asisknown a belt driven by an electric motor is capable of transmitting rotation at a very high speed, without fthe objectional wear and noise that would be present with gears or the like. By having this spindle rotate at very high speed, the small feed rubber 2 can also be rotated at fairly high speed notwithstanding a reduction of speed fromthe worm to gear drive. Furthermore the use of the'worm in this way permits the use of a power means which is completely beneath the level of the small feed rubber 2 and scarcely takes up any more vertical height than the thickness of the worm gear itself. On Athe other hand this mechanism does not project either into or under the table where it would interfere with the oil pan, or beyond the small feed rubber into the path of the matter to be canceled. In other words, the yworm gear and the worm are substantially vcovered by the feed rubber, not projecting beyond the periphery of the same intothe path of the mail matter, nor to either side to such an extent as to be an obstruction to the free movement of the hand of the operator. The mechanism furthermore does not project laterally so as to 'interfere with the large feed rubber. Thus all the conditions mentioned in the preliminary part of the specification are obtained, and a power drive is provided which can be used whenever desired c'. whenever a power source is available.

IWhen the hand power drive for the machine is used, the worm drive must of course be disconnected for obvious reasons, andfor this reason the best practical construction embodies a tube or sleeve 12, carrying the two bearings or journals 8 for the worm spindle. This tube or sleeve is received in a split yoke or frame 18 having a. screw 14, by which the same can be tightened on the tube or sleeve to hold the same in any position. When the canceling machineV is worked by hand the set screw 14: is loosened and the tube or sleeve `12 pulled out so as 65 to withdraw the worm from the worm gear, after which the machine is entirely free to operate without being hampered at all by the power connection.. y i j They worm, the worm vspindle and the worm gear, are all cased in a suitable housing 15 secured tothe surface of the'table which permits theparts to be lubricated, withoutex'posing the matter to be canceled tolubricant on the one hand, and protecting the parts from grit and dust from the canceledk matter'on .the other hand. The housing is compactly built around the worm geark and the worm, so that the entire housing is substantially located beneath the feed rubber, except for the 'worm shaft extension in one direction. Thus the device neither interferes with the movement of the articles to becancelechnor the hands of the operator.

What is claimed is c 85 1. In a canceling machine, a vertically eX- tending shaft, a` feed rubber fixed tofsaid shaft, a horizontal table on which the matter to be-canceled stands when pressed against vthe feed rubber, a worm gear for the feed rubber below the 'feed rubber and substantiallyv covered thereby and above the table, anda spindle having a worm extending along the upper surface of the table-and meshing with said worm gear, said spindle extending from one side of said worm and saidworm being out of the pat-h of the matter to be canceled. y I lf2. In a canceling machine, a vertically eX- tending shaft, a feed rubber fixed to said shaft, a horizontal table on which the matter to `be canceled stands when pressed against the feed rubber, a worm gear for the feed rubber below the feed rubber and above the' table, a worm meshing with said worm gear, a spindle extending from the side of the worm along the upper surface of the table, and a housing substantially located beneath the feed rubber and covering the worm spindle the worm and the worm gear to prevent the lubricant thereon from reaching the mail matter and the dust from the mail matter from reaching the said parts.

3. In a canceling machine, a feed rubber, a table on which the matter to be canceled stands when pressed against the feed rubber, a worm gear for the feed rubber below the feed rubber and above the table, a spindle having a worm extending along the upper surface ofthe table and meshing with said worm gear, and meanskfor adjustably locating said wormy spindle in different longitudinal positions whereby the drive can be disconnected.
