No. 19337.—12th April, 1905.—CHARLES W. MERRILL, of Lead, South Dakota, United States of America, Metallurgical Engineer. Pressure-filter and process for removing solid, semi-solid, or unfilterable material from the containers thereof.

Extract from Specification.—My improved process consists in so constructing the containers of a filter-press as to permit removing the solid or semi-solid material from the containers without separating the units of the pressure-filter. To accomplish this I provide an inlet for each distance frame or container through which a liquid vapour or gas is introduced under pressure, and the solid, semi-solid, or unfilterable contents is sluiced or forced out through an exit from said frame. This exit may be an independent outlet or it may be the opening through which the material to be filtered is originally introduced. Again, in the operation of filter-presses or similar pressure-filters, and the treatment of the contents thereof, it is frequently advisable to remove the liquid air or gas from the interstitial spaces of the solid or semi-solid contents of the containers. Containers which have heretofore been used in the ordinary forms of filter-presses have been constructed with unbroken or continuous inside surfaces which are parallel to the main or longitudinal axis of the filter-press or with corrugations. It frequently happens that after filling the containers with solid or semi-solid material a certain amount of settling occurs, particularly when containers of large dimensions are used. As a result there is a loss of contact between the solid or semi-solid material and the inner surface of the container, as a result of which the replacing gas or liquid passes through the space so formed instead of through the solid contents itself. A further difficulty presents itself, as the effect of any shrinkage of the cake of precipitated mass in the container, which generally occurs, is to leave a channel or space of least resistance through which the liquid or gas used in treating the material will pass, for the reason that the shrinkage will separate the cake from the inner surface of the container and leave an open channel through which the air or gas when used in the operation conducted in the filter-press will rush, instead of slowly permeating the cake and forcing the water out ahead of it, which is always desirable. Where, however, a rib is made of the inverted keystone form shown in the drawings, the cake will form solidly around it, and as the large end of the keystone projects into the container the effect will be to prevent the cake from shrinking away from the inner surface of the container or rib, and in this way to form a tight joint between the wedge-shaped rib and the cake.
[NOTE.—The above extract from the specification is inserted in place of the claims.]

No. 19368.—19th April, 1905.—UNITED SHOE MACHINERY COMPANY, of Paterson, in the State of New Jersey, United States of America, a corporation duly organized under the laws of said State of New Jersey, and having a place of business at 205 Lincoln Street, Boston, Massachusetts, United States of America (assignees of William Hedges Taylor, of Baltimore, Maryland, United States of America, Shoeworker). Improvements in or relating to heels and heel-nailing machines.*

Extract from Specification.—This invention relates to a boot or shoe in which this result is obtained by inserting the nails in the heel in a position inclined from the face of the heel towards the rear of the heel, the inclination of the nails being uniform so that they lie in a parallel relation. Preferably the nails are driven through the heel into the heel-seat of the shoe and their points are clinched towards the rear of the heel. A top lift may be secured to the heel by being spanked on the ends of the inclined nails, which may project from the face of the heel for this purpose, the top lift being driven in this operation in a direction parallel with that in which the nails incline. This invention comprises also a heel-nailing machine which may be used to perform the operations above described. In the machine embodying this part of the invention the nails are driven in an inclined direction by supporting the heel obliquely with relation to the path of the nails in the
