235 F. 896 | 7th Cir. | 1916
The so-called attachment consists of a detachable button chute or tube in a machine for attaching buttons to shoes, through which chute the buttons pass from the hopper, or source of the button supply, to the place of attachment to the fabric. The commercial Elliott machine, on the market for years prior to filing application for this patent, had the same kind of chute, save only that it was not readily detachable, but was so placed that to remove it required some dismemberment of the machine. However, the patent in question does not purport to cover the Elliott machine in its reconstructed form to admit of ready detachment of the chute, but, as granted, limits the award to this inventor to the elements of that machine as combined with the distinctive feature of a detachable button chute.
The button chute of the patent, as well 'as of the machine in long prior use, has a retaining spring or device at its lower end to prevent the column of buttons, which descend in the chute by gravity, from running out. A sort of feed finger in the machine reaches in between
The advantage of ready detachahility is stated in the specification of the patent to be that a chute made for certain sized buttons may be readily removed, and another chute attached, constructed and adjusted to take care of buttons of a different size, thus enabling the same machine to operate with different sized buttons by merely changing its button chute. There is no difference in the mechanism or operation of the old and the new chutes; hut it is claimed that under Llie old method, unless the machine were taken apart and another chute substituted whenever it was desired to use buttons of different size from those for which the chute was then adjusted, it was necessary to have several of the machines, each with its chute having the retaining spring or device at a point where it will accommodate the different size of buttons.
But, when the new machine was equipped with a chute for a given size of button, it was, in all essential respects, like the old Elliott machine equipped for the like size button, and when equipped with a chute for a different size of button it was, in function and operation, just like another of the old machines arranged for such size of button. For the seven years during which the application was pending in the Patent Office the applicant sought repeatedly, but vainly, to secure claims upon a plurality of interchangeable chutes, severally adjusted for different sized buttons, which undertakings were as persistently opposed by the Patent Office, and all such claims were refused, and the claims finally allowed contain no reference whatever to a plurality or interchangeability of chutes, or to chutes of varying; construction 01-adjustment to admit of using different chutes for different sized buttons with same machine. In rejecting a claim which described a plurality or scries of these chutes, the Patent Office properly said:
“A description of the machine is complete which includes only one chuto, and a description including a series of chutes embraces more than is comprised in the machine. Those chutes which are temporarily disconnected from the machine are wholly separate from, and independent of it, and fox*m no part thereof, and a claim which attempts to cover them all together covers an aggregation.”
Plurality or interchangeability of chutes not having been patented to appellee, there is no infringement in their employment by another.
The action seems to be based on the function or the advantageous possibilities in the employment of a plurality of chutes, as stated
The opinion of the District Court, reported in 224 Fed. 502, discusses more fully these propositions, and with, its reasoning and conclusions we are in accord.
The decree of the District Court is affirmed.
