Opinion

HALE, District Judge.

This case comes before the court upon appeal from the descree of the District Court for the Massachusetts District, holding United States letters patent to F. W. Storek, No. 1,365,803, of January 18, 1921,. to be valid and infringed!

The patent discloses a machine for sealing envelopes, wherein a large number of envelopes are placed in a pile in a feeding hopper and fe(l successively along a moving belt to a moistening device, inserted between the flap and the body of the envelope, thereby moistening the gummed surface of the flap. As'they pass rapidly by the moistener the envelopes are projected into a receiver or stack, wherein they accumulate in a pile. The contact 'of the envelopes in the stack, with the slight weight, and the lapse of m few seconds, closes the flaps and establishes and maintains contact of the moistened flaps with the backs of the envelopes, so as to seal them.

The plaintiff says that Storek, the inventor, intended the machine of the patent in suit to be an improvement upon Lis earlier machine which is shown in model F under his patent No. 1,194,568, of August 15,1916. That machine was equipped with a spring-pressed sealing plate, and was used with a receiving hopper upon which were these directions :

“Sealing: Place the foldable- envelope receiving hopper at end of machine corresponding to size of envelopes (see cut): This is important, for owing to the high speed of the standard the glue is not in its best sticking condition whilst the envelopés pass through the machine; hence sealing.is not completed until the envelopes are stacked in the receiving hopper and a quick hand pressure applied. Then remove the staek and I9y.it on the. táble flap side down. If this instruction is observed and the wick kept clean, we guarantee perfect results.”

The idea of the patentee was to eliminate the sealing plate. He tells the story of invention quite clearly in the specification. He says that he knew the practice to provide means for sealing the envelope by pressure of the. flap, after moistening, against the back of the envelope, as it passed through the machine, the pressure to be effected either by sealing plate or sealing rollers. He says he found that such means were not sufficient to effectively seal the flap; that he found the sealing could not be done by pressure so well as by contact for a few seconds between the gummed flap and the back of the envelope, in order to give time for the moistened gum to penetrate the paper; and that hence he provided for actual and complete sealing in a receiving hopper where the envelopes are stacked with moistened flaps for a long enough time to permit the weight of the staek to hold the flaps in engagement with the backs of the envelopes; that by eliminating the sealing plate or rollers which had been located between the moistener and the receiving hopper, and placing the hopper immediately adjacent to the moistening means, he could eliminate what he calls “a prolific source of trouble with the envelope sealing machine as such devices, because of their squeezing effect, force the water and gum out from the edges of the flap, and spread them on the back of the envelope, thus causing the mechanism to be fouled with gum so that a frequent cleaning is necessary.”

He also calls attention to the fact that the old sealing rollers have the fault of dislocating the flap, especially when filled with bulky inclosures; he says that by his invention he makes a shorter, simpler, and more compact and more cheaply manufactured machine. His invention is set forth in claim 10, as follows:'

“10. In a device of the character specified the combination of' a feeding means to support and forward the envelopes to be operated upon, a flap-moistening means and a receiver located immediately adjacent to said flap-moistening means to collect the envelopes successively iri a self-sealing stack for the purpose specified.”

This claim brings before us a machine having three substantial elements in combination: First, a feeding means to forward the. envelopes; second, a flap-moistening means; third, a receiver located immediately adjacent to the flap-moistening means, to collect the envelopes successively in a self- ' sealing staek. -

The patentee was endeavoring to produce a machine for rapid sealing of a large number of envelopes. He found that, in the prior art, pressure was thought necessary to effect some part of the sealing, leaving the completion of the sealing to be done in a receiver at the end; as one witness has put it, under favorable auspices and under “favorable climatic conditions,” the sealing would be completed before the envelopes reached the end of their journey through the machine. The importance of the receiving hopper at the end of the machine was to supplement the pressure which had been applied as the envelope was on its way [21]*21through the machine; and the receiver was regarded as important only from the faet that, at the high speed at which the envelopes were moved, the glue would not stick while the envelopes were passing through the machine, and hence the sealing could not be fully completed until the envelopes arrived at the stack.

The idea of the inventor was to find a means to pass the envelopes through the feeding apparatus and the flap-moistening means as quickly as possible, without attempting to apply any pressure to it, thus greatly increasing the speed of the movement and leaving the whole of the operation of sealing to be effected in the receiving stack; for he had found by repeated experiments that it was not pressure that effected the sealing, especially where that pressure was applied very quickly, but that contact plus a few seconds of time was capable of doing the whole work of sealing. The receiving hopper was the one operating device by which the whole of the sealing was accomplished, thereby avoiding the harmful results of the pressure applied while the envelopes were passing through the machine, and effecting a much simpler and more rapid movement of the envelopes.

Judge Morton held the patent to be valid. In so holding, he gave deference to the opinion of Judge Anderson in this Circuit, in Standard Envelope Sealer Manufacturing Co. v. Graywood Manufacturing Co., 1 F.(2d) 667, in which case Judge Anderson held: “The old use was that of partial utilization of time and gravity in the sealing stack to complete the sealing process, whereas the new use is of utilization of time and gravity pressure in the sealing stack to perform the entire function. * * * He [the patentee] put the whole sealing job upon the stack; whereas before it had been begun in the machine and completed in the stack.” “This is a new concept, and, in the plaintiff’s machine, is covered by the device in which the sealing stack is put immediately adjacent to the moistening device, thus eliminating any place for a pressure plate.” We are of the opinion that Judge Anderson and Judge Morton were right in holding the patent valid.

The patentee was operating in an old art. He found many machines for sealing envelopes. Some of them had been successful. All of them showed means of feeding, for moistening, and for applying mechanical pressure. Stacks had long been used, and in many cases they had been used “to complete the sealing.” Patents have been brought before us which involve this use. Both the patented and the unpatented art had used stacks in completing the sealing, but it had always been thought necessary to use mechanical pressure as the envelopes passed through the machine.
