Filed D80. 50, 1946 2 Sheets-Sheet 2 A \\%N%\ %W Patented Feb. 17, 1948 UNITED STATES PATENT OFFICE SHUTTLE CHECK Napoleon Lamarche, Lowell, Mass. Application December 30, 1946, Serial No. 719,265 2 Claims. (CL 139-185) The invention relates to shuttle checks for looms and more particularly to checks associated with shuttle boxes, as seen for example in Figs. to 8 of the drawing of my United States Patent 2,305,534 of December 15, 1942. Each shuttle check must be pressed inwardly by a spring device, and the present invention aims to provide a simple inexpensive, eifective and long-lived attachment whereby the required number of such spring devices may be mounted in operative relation with the check or checks.
Figure l of the accompanying drawings is a front elevation, partly broken away, showing the invention attached to a shuttle box and cooperating with the shuttle checks thereof.
Fig. 2 is a top plan view of the parts shown in Fig. 1.
Figs. 3, 4 and 5 are sectional views on the correspondinglynumbered lines of Fig. 1.
Fig. 6 is a perspective view showing the major portion of the attachment.
A preferred construction has been illustrated and will be rather specifically described, with the understanding, however, that within the scope of the invention as claimed, variations may be made. The particular form of the invention disclosed cooperates with the four shuttle checks of the fur-cell shuttle box, but the invention may be constructed for coaction with any desired number of shuttle checks, even one.
In describing the invention, the terms outer," "inner" and lnwardly" will be used to denote directions unidirectional with the lay, and front," rear. forwardly" and rearwardly" to denote directions at right angles to the lay.
A shuttle box I is shown having superposed cells 8 and appropriate shuttle checks 9 at the usual open front sides oi! said cells, said checks having forwardly oflset outer ends provided with adjusting screws l9. At the outer end of the shuttle box 1, the horizontal webs in which form the tops and bottoms o! the cells 8, are integrally joined to a vertical plate I I in the usual way, this plate being mentioned simply because it is to this element of the shuttle box that the attachment is secured. As customarily manufactured, the plate I i is formed near its outer edge with a vertical rib l2 and with horizontal ribs l3 projecting inwardly from said rib l2, and is formed at its inner edge with other horizontal ribs I, all of said ribs being upon the front side of said plate H. Regardless of this ribbed formation of the plate H, the attachment of the present invention is so designed that it may be solidly; fastened against the front side of said plate.
The attachment includes a vertically elongated attaching bar ii for disposition at the front side of the plate ll behind the forwardly offset ends of the checks 9, the rear side of said attaching bar [5 being formed with a. longitudinal rib l6 for contact with the ribs l2 and I3, and being formed also with spaced vertical ribs ii for contact with plate ll between the ribs H. The attaching bar [5 is solidly secured to the plate II by a number of cap screws l8. When the shuttle checks 9 are of the construction disclosed in the above mentioned patent, the adjusting screws IQ of said checks may well contact with the heads of the attaching screws III, as shown.
Upper and lower horizontal arms 28 and 2i are integrally joined to the upper and lower ends of the attaching bar 18 and project beyond the inner edge thereof, said arms being located above and below the forwardly offset outer ends of the checks 9, respectively, Extending between the inner ends of these arms and integrally joined thereto, is a vertical bridge bar 22 which, when the attachment is fastened to the shuttle box, is forwardly spaced from the checks 9 and inwardly spaced from the forwardly offset outer ends of said checks 9. This bridge bar 22 carries a. pinrality of sockets 23 which, when the attachment is applied, open rearwardly toward the checks 9. The sockets 23 contain coiled compression springs 24 which exert rearward pressure on the checks 9, and said sockets are provided with suitable adgusting devices 25 for varying the strengths of said springs, thereby causing said checks to exert the necessary frictional braking force upon the shuttles.
From the foregoing, taken in connection with the accompanying drawings, it will be seen that novel and advantageous provision has been made for carrying out the object of the invention, and while preferences have been disclosed, attention is again invited to the possibility of making variations within the scope of the invention as claimed.
I claim:
1. In combination with a shuttle box and a shuttle check at the front side thereof, said check having a forwardly oil'set outer end spaced in front of the outer end of said shuttle box; a ver tical attaching bar spaced behind said forward- 1y oilset outer end of said check, means securing said attaching bar against the front side of said shuttle box, an upper arm integral with the upper end of said attaching bar and disposed over said forwardly oilset outer end of said check, a lower arm integral with the lower end of said attaching bar and disposed under said forwardly oflset outer end of said check, said upper and lower arms extending inwardly from said attaching bar toward the inner end of said shuttle box, a vertical bridge bar extending between the inner ends of said upper and lower arms and integrally joined thereto, said bridge bar being inwardly spaced from said forwardly oflset outer end of said check and being forwardly spaced from the adjacent portion of said eheck said bridge bar having a rearwardly open socket in front of said check, a spring seated in said socket and abutting the front side of said check, and an adjusting device for said spring threaded through the front end of said socket.
2. In combination with a shuttlebox havin vertically spaced shuttle cells, and shuttle checks at the front sides of said cells, said checks having forwardly offset outer ends spaced in front of the outer end of said shuttle box; and adjusting screws threaded through said ofiset outer ends of said checks and projecting rearwardly there from; a vertical attaching bar spaced behind said forwardly offset outer ends of said checksand said adjusting screws thereof, vertically spaced l5 fasteners securing said attaching bar to the front side of said shuttle box and having heads abutting the aforesaid adjusting screws, an upper arm integral with the upper end of said attaching bar and disposed over said forwardly offset outer ends of said checks, 9. lower arm integral with the lower end of said attaching bar and disposed under said forwardly ofiset outer ends of said checks. said upper and lower arms extending inwardly from said attaching bar toward the inner end of said shuttle box, a vertical bridge bar extending between the inner ends of said upper and lower arms and integrally joined thereto, said bridge bar being inwardly spaced from said forwardly offset outer ends of said checks and being forwardly spaced from the adjacent portions of said checks, said bridge bar having rearwardly open sockets in front of said checks, springs seated in said sockets and abutting the front sides of said checks, and adjusting devices for said springs threaded through the front ends of said sockets.
