| A. J. Sangster - patent attorneyThis invention relates to an improved machine for making barrel hoops, and the object of the invention is to produce a machine for the purpose of forming wood barrel hoops and fastening the overlapping ends of the hoops by means of staples driven there through; a machine which is comparatively light in weight but unusually strong and durable; practically automatic in operation, yet simple in construction and devoid of all complicated mechanisms and intricate movements which not only render the machine bulky, but easily get out of order, necessitating frequent repairs. Among the special features of this new and improved barrel hoop making machine, the most prominent are; a device for forming, sizing and holding the barrel hoop; an automatic mechanism for starting and stopping the machine; a staple forming and driving mechanism; a wire feeding mechanism with a selective attachment whereby any particular wire-feed may be cut out of operation; and an automatic staple clenching mechanism for clenching the ends of the staples after they are driven through the overlapping barrel hoop ends.I claim;1. In a machine of the class described, a machine frame and a hoop form consisting of an upper member of semi-circular segmeutal form, a lower member of similar semi-circular segmental form hinged at one side to the upper member, a cross bar extending between the lower end of the upper member, a depending vertical frame member pivoted at its lower end to the machine frame and rigidly secured at its upper end to the cross bar of the upper member, a foot treadle and a connecting rod pivoted at its lower end to the foot treadle and at its upper end to the depending vertical frame member at a distance above its lower pivoting point.2. In a machine of the class described, a machine frame and a hoop, form consisting of two semi-circular segmental members hinged together at one side; the upper member being provided with a cross bar extending between its lower ends, a depending vertical frame member pivoted at its lower end to the machine frame, and rigidly secured at its upper end to the cross bar of the upper member, and means connected to the depending vertical frame member for swinging the hoop form into hoop stapling position, and also expanding said hoop form.3. In a machine of the class described a main frame having an outwardly projecting portion, a vertical swing frame pivoted at its lower end to the outwardly projecting portion of the main frame, an expansible hoop form rigidly fastened to the upper end of the vertical swing frame, stapling mechanism supported in the main frame and a single manually operated means for simultaneously swinging the swing frame into stapling position and also expanding the hoop form.4. In a machine of the class described, a machine frame, stapling mechanism in said frame, an expansible hoop form consisting of two hinged together members one of which is pivotally supported from the machine frame, and manually swinging and expanding means having a rod connected to the other member.5. In a machine of the class described, a machine frame, stapling mechanism in said frame, an expansible hoop form consisting of two hinged together members one of which is pivotally supported from the machine frame, a foot treadle, and a rod connecting the foot treadle to the other member go of the hoop form.6. In a machine of the class described, a main frame having an outwardly projecting portion, a vertical swing frame pivoted at its lower end to the outwardly projecting portion of the main frame, an expansible hoop form rigidly fastened to the upper end of the vertical swing frame, stapling mechanism supported in the main frame and a single manually operated means for simultaneously swinging the swing frame into stapling position and also expanding the hoop form; said means including a foot treadle and a connecting rod extending from the foot treadle and connected to the vertical swing frame.7. In a hoop stapling apparatus of the character designated, the combination with stapling mechanism, of a swinging hoop former, a foot treadle connected to the hoop former for swinging the same into position for stapling, and means automatically actuated by the swinging movement of the hoop former for clamping the ends of the hoop on the former, substantially in the manner and for the purpose described.8. In a hoop stapling apparatus of the character designated, the combination with stapling mechanism, of a swinging hoop former, a foot treadle connected to the hoop no former for swinging the same into position for stapling, mechanism for automatically clamping the ends of the hoop in position on said swinging former as it swings into stapling position, and means for automatically releasing such clamping mechanism as it swings back out of position, substantially in the manner and for the purpose described.9. In a hoop stapling machine, a machine frame, and a swinging hoop former consisting of a fixed upper segmental section, a lower segmental section pivotally suspended at one end from said upper section and a vertical member fastened at its upper end to the fixed upper .section and pivoted at its lower end to the machine frame.10. In a hoop stapling machine, a machine frame, and a swinging hoop former, consisting of a fixed upper segmental section, a lower segmental section pivotally suspended at one end from said upper section; said upper section having a cross bar and a vertical member fastened at its upper end to the cross bar of the upper member and pivoted at its lower end to the machine frame.11. In a machine of the class described, a main frame and a hoop form composed of hinged together sections, a vertically depending member rigidly fastened at its upper end to one section and pivoted at its lower end to the main frame and means for .moving the other section to expand the hoop form; said means being so constructed and arranged that it also swings the depending member on its pivot as it expands the hoop form.12. In a machine of the class described, a main frame, an expansible hoop form, a depending member rigidly fastened at its upper end to said hoop form and pivoted at its lower end to the main frame and means for simultaneously expanding the hoop form and swinging the depending member on its pivot toward the main frame.13. In a machine of the class described the combination with stapling mechanism and a hoop form movable into and out of position with reference to the stapling mechanism, of a starting and stopping mechanism including a clutch which is automatically controlled by the movement of the hoop form.14. In a machine of the class described, the combination with stapling mechanism, and a hoop form movable into and out of position with reference to the stapling mechanism, of a starting and stopping, mechanism including an automatically engaged and disengaged clutch and a toggle connected to said clutch and the movable hoop form.15. In a machine of the class described, the combination with staple driving mechanism of a hoop form movable into and out of operative position with respect to the staple driving mechanism and means whereby the hoop form expands to size a hoop fitted thereon as it moves into operative position relative to the staple driving mechanism.16. In a machine of the class described, a swing frame carrying a hoop form, means for swinging said frame and staple driving mechanism automatically thrown in operation when the swing frame is swung in position. |
