Definitions

  • the present invention is related to a hand riveter which has a jaw case movable forward and backward by opening and closing handles for setting rivets as desired.
  • a closure member (such as a barrel) for holding the base end of a spring for pressing a jaw pusher accommodated in a jaw case is screwed in the upper end of the jaw case and thereby connected to the jaw case, with the spring enclosed in the jaw case along with other jaw members, so that the spring merely has the function of pressing the jaw members only.
  • Such hand riveters generally used are divided into two types: one which has another spring for opening the handles, and the other which is not provided with such an opening spring.
  • the spring acting to open the handles to a full extent holds the forward end of the jaw case in bearing contact with the forward end inner wall of a tubular jaw case housing, consequently maintaining the jaws in an opened position at all times, with their outer ends in contact with the inner end of the nose piece.
  • the riveter has the drawback that the rivet inserted through the jaws will slip off inadvertently when the jaws are directed downward.
  • the riveter of the latter type usually has its handles closed, and the jaws are therefore held closed at all times, so that the riveter requires the cumbersome procedure of opening the handles by hand to open the jaws every time a rivet is to be inserted through the jaws. This seriously reduces the efficiency of rivet setting operation.
  • the present invention provides a hand riveter having a jaw case which is movable forward and backward by opening and closing its handles for setting rivets as desired,which riveter is characterized in that a closure member for holding the base end of a spring for pressing a jaw pusher accommodated in the jaw case is attached to an upper portion of a tubular jas case housing at a required distance from the jaw case, the handles being operable by the force of the pressing spring.
  • a single spring is used for pressing a jaw pusher accommodated in the jaw case and also for opening the handles to render the riveter simple in construction and inexpensive md to assure a very smooth and easy rivet setting operation.
  • a hand riveter main body having a lower handle 2.
  • a tubular jas case housing 4 which is directed downward, is formed at the front end of a head frame 3 included in the main body.
  • Jaws 5, a jaw pusher 6 and a spring 7 for pressing the jaw pusher are inserted in this order in a jaw case 8, which is fitted in the housing 4.
  • the base end of the pressing spring 7 projecting outward from the upper end of the jaw case 8 bears against and is held by a closure member 9-in the form of a bored barrel and screwed in the upper end of the housing 4.
  • the closure member 9 is spaced from the upper end of the jaw case 8 by a required distance.
  • An upper handle 10 is pivoted at a boss portion to the main body 1.
  • the handle 10 is formed at its front end with a bifurcated portion 11 which is fittingly engaged in recesses 12 formed at an upper portion of the jaw case 8 on the opposite sides of its outer periphery so that the upper handle 10, when moved upward or downward, advances or retracts the jaw case 8 within the housing 4.
  • the upper handle 10 is biased by the force of the jaw pusher pressing spring 7 so that the handles 2 and 10 can usually be in an open state.
  • the drawings show a nose piece 13 screwed inthe forward end of the housing 4, interchangeable nose pieces 13 1 which are different in bore diameter and length, a blind rivet 14 and workpieces 15 to be joined together.
  • the hand riveter is first held in the position of F ig. 1 so that the upper handle 10 will not lower under gravity.
  • the blind rivet 14 can then be easily inserted through the jaw assembly because the jaws 5 are fully opened (see Fig. 3).
  • the jaws 5 are closed to reliably grip the blind rivet 14 as shown in Fig.4. This eliminates the likelihood that the blind rivet will slip off the jaws, even when the riveter is used as directed downward for riveting, thus assuring the desired rivet setting operation.
  • the present invention in which the spring for pressing the jaw pusher is used also for opening the handles eliminates the use of a spring for opening the handles to render the riveter simple in construction and inexpensive to make while completely overcoming the drawbacks of the two types of hand riveters described.
  • the invention therefore assures a very smooth and easy rivet setting operation.
  • the force of the pusher pressing spring is so determined that when the riveter is used for riveting, the upper handle will slightly lower under gravity against the force of the spring.
