SEWING MACHINE.--L.W. Lathrop, Nyack, N.Y.--This invention relates to improvements in sewing machines, and consists in certain improvements in mechanism for forming the loop, and for conveying the binding thread through the same, in a manner to prevent the contact of the binding thread spool, or its carrier, with the thread of the needle, and thereby to avoid wearing the same, and to produce more easily operating parts; also, a secure, permanent, and reliable arrangement of apparatus, and calculated also to be more certain to form the stitch. POETABLE DERRICK.--J.R. Hammond, Sedalia, Mo.--This invention has for its object to furnish an improved derrick, simple in construction, effective in operation, and easily moved from place to place, designed especially for use in connection with the improved rake, thrasher, loader, and stacker, patented by the same inventor Nov. 30, 1869, but equally applicable for other uses. WAGON SEAT FASTENER.--Charles Collins, Vernon Centre, N.Y.--This invention relates to improvements in means for holding detachable wagon or sleigh seats to the boxes, and consists in the application to the seat risers of hooks with spring stops, adapted for engaging staples in the boxes below the said hooks, and for being held in such engagement by the spring stops, until disengaged by the operator for removing the seats. VELOCIPEDE.--William Volk, Buffalo, N.Y.--This invention relates to a new three-wheeled velocipede, which is so arranged that the driving wheels, although mounted on separate axles, will make equal numbers of revolutions, as long as the machine is to be kept in a straight direction, while they can be disconnected when the device is to be turned in a circle. COFFIN HANDLES.--Clark Strong, Winsted, Conn.--This invention relates to new and useful improvements in coffin handles, and consists in the construction, arrangement, and combination of parts. LOOM.--Lyman Stone, Nelson, N.H.--This invention relates to improvements in power looms, and has for its principal object to provide an arrangement and construction of the same, calculated to furnish looms of equal or greater efficiency than those now in use, but occupying very much less space, so as to economize materially in room, where large numbers are used on a floor, as is the case in factories; not only in respect of the space occupied by the loom itself, but also in respect of the space required for the passages or aisles between the rows of looms. The invention also comprises improved let-off and take-up mechanisms, also, an improvement in cloth beams; also, an improved picker motion, inducing a novel adjusting arrangement for the picker operating cams, also, an improved construction of treadle cams, whereby an equal capacity of throw is obtained with less size and friction, and with less power, and whereby they are guarded to prevent accidents to the attendant while cleaning when the loom is in operation.
