SPECIFICATION forming part of Letters Patent No. 555,595, dated March 3, 1896.
Application filed- January 22, 1895. Serial No. 535,775. (No model.)
To all whom it may concern.-
Be it known that I, ERASTUS WooDwARD, of Somerville, in the county of Middlesex and State of Massachusetts, have invented a new and useful Improvement in Tacking Machines for Use More Especially in Lasting Boots and Shoes, of which the following is a specification.
My invention relates to that class of naildrivers which are ineffective except at the instant when they are set in operation and then perform one operative action and immediately become ineffective again.
It consists of a machine in which there is a tacking mechanism and a jack-lifting mechanism each separate from the other. The tacking mechanism is brought into operation directly by the depressing of the treadle, and a further movement of the treadle throws a clutch, which causes the engagement of the jack-lifting mechanism with the main shaft or other means of applying power. Thus the operator is relieved from the strain which the constant lifting of the jack will cause and at the same time has it in his power to drive a single tack by a continuation of the same movement of the treadle.
I have shown my invention applied to a tacking mechanism of the kind described in Letters Patent No. 47 3,136, granted to me April 19, 1882, in which the driver is constantly running and at the proper time a tack is fed under the driver.
In the drawings is shown the best form of machine embodying my invention now known to me.
Figure 1 is an elevation, and Fig. 2 a detail, showing the hook mechanism.
A is the tack-driving machine of the form shown in my previous patent, No. 473,136, to which reference is made for the details of construction. It is mounted on the post B. R is the operating-rod which operates the shaft J carrying the cam F, as in that patent. I prefer, however, to form the upper end of this rod R with a hook r to engage with the notched wheel 1" on shaft J, instead of the arrangement of pawls and ratchet referred to in my previous patent. The lower end of this rod passes through a hole in a rockerarm D mounted on a stud E, being held in place by a collar d and set-screw. The hub which carries the arm D is notched at cl. 0 is the treadle which carries a toe c engaging with the said notch. I prefer to make this toe one arm of a bell-crank, the other arm, 0, of which extends forward and is bolted to the treadle O, a slot being provided for a bolt-hole, so that the position of the parts may be adjusted.
By depressing the treadle it will be seen that a downward movement is given to the arm D, which pulls down the rod R and causes it to perform the function which it performs in my previous patent.
H is a loose pulley operated by a belt H, as in my previous patent. H is a clutch mounted to rotate with the shaft H The pulley H slides on the shaft H and carries a grooved wheel. A pin on the upper end of the bell-crank H fits into the groove in this wheel, the other end of the bell-crank being adjustably connected at h to the treadle C. The front end of the shaft H carries a beveled gear H, which engages with the segment I-I mounted on one end of a lever system K,
the other end of which supports the jack-rod K, the lever system being such as is well known in machines of this kind for giving to a jack a vertical movement.
It will be seen that upon depressing the treadle 0 two acts take place. The rod R is pulled down, so that the tack-feeding mechanism is thrown into operation and one tack is fed and the clutch H is thrown into connection with the pulley II, so that the jack is lifted by power; and, moreover, it will be noticed that the connection between the clutch and the treadle is adjustable, so that the relative timing of these parts may be changed according to circumstances.
The advantages of this mechanism are mainly that in the machine of my prior patent above referred to and in that class of machines in which the lifting of the jack causes the nozzle to be lifted to start the tack-driving operation there is a tendency or temptation to the operator who is desirous of being quick at his work to withdraw the shoe be fore the tack has been fully driven, while in my present machine it is possible to so adjust the parts that the driving operation may be begun before the work is quite in position to receive the tack. In fact, the work will always get into position in time to receive the final impact of the hammer or driver, but the operator will not have a chance to withdraw the work before the tack is fully driven.
In carrying out my present invention the rod R or other corresponding part maybe so connected that when depressed it will start the main shaft and so cause the operation of the entire driving mechanism instead of merely the operation of the tack feeding mechanism, as my present invention consists in a machine comprising a jack-lifting fea ture and a tack-driving feature, both of which are rendered effective directly from the same treadle or other part adapted for the purpose, each being otherwise entirely independent of the other. I prefer to use a treadle-lever for this purpose, as it is easily accessible to the operator.
hat I claim as my invention is 1. In a tacking-machine,a jack-support and power-lifting mechanism,and a tackingmechanism normally inoperative, each independent of the other, in combination with atreadle connected to said tacking mechanism and to a clutch adapted to engage said power jacklifting mechanism, all as set forth.
2. In a tacking-machine which is normally ineffective to drive a tack, a tack-feed starter, mechanism for lifting the jack independent thereof, and a clutch adapted to connect said jack lifting mechanism with a source of power, in combination with a treadle connected to the tack-feed starter and said clutch, all as set forth.
In witness whereof I have hereunto set my hand this 21st day of January, 1895.
ERASTUS WOODWARD.
