摘要： A safety device particularly suitable for rifles and carbines consisting of a rod connected to a lever which can be inserted through a bore in the back side of the rifle hammer when the hammer is extended slightly past the fully cocked position. The rod can engage the hammer and prevent the hammer from moving regardless of the motion of the trigger.

摘要： The invention is concerned with a safety for a revolver in which the release button or thumb piece is provided with three positions, one of which is the normally open and non-firing position, a second of which is an intermediate, but normally closed, non-firing position, and a third of which is the normally closed and firing position. A spring mechanism is provided to hold the release button in its intermediate position while permitting movement to the first or normally open, or non-firing position, but preventing movement to the third or normally closed position or firing position. The button is connected with the conventional pawl blocking mechanism which prevents the firing of the ammunition when the button is in the intermediate or normally open position. In the intermediate position, while the mounting cylinder is closed, the pawl blocking mechanism prevents the pawl from actuating the ammunition in response to movement of the triggering mechanism, so as to provide for a safety while permitting the gun to be in a ready to fire position. The mechanism also includes a button engaging element which is held in place by means of a spring device, and a lever is attached to the bar to overcome the spring force so as to permit the button to be moved to the normally firing position.

摘要翻译： 本发明涉及一种左轮手枪的安全性，其中释放按钮或拇指片具有三个位置，其中一个位置是常开和非点火位置，其中一个是中间的，但是常闭， 发射位置，其中三分之一是常闭和发射位置。 提供弹簧机构以将释放按钮保持在其中间位置，同时允许移动到第一或常开或非点火位置，但是防止移动到第三或正常关闭位置或发射位置。 该按钮与常规的棘爪阻挡机构连接，当按钮处于中间或正常打开位置时防止弹药的点燃。 在中间位置，当安装筒关闭时，棘爪阻挡机构防止棘爪响应于触发机构的移动来致动弹药，以便提供安全性，同时允许枪准备着火 位置。 该机构还包括通过弹簧装置保持就位的按钮接合元件，并且杠杆附接到杆以克服弹簧力，以便允许按钮移动到正常点火位置。

摘要： A safety for revolvers comprising a revolver frame, having a recess therethrough, the recess being formed and having front and rear ends with at least one abutment catch intermediate the ends thereof. A firing assembly includes a hammer pivotally mounted in the frame and has a first portion pivotally operatively connected therewith. A thumbpiece is slidably disposed on the outside of the frame and projects through the recess. The thumbpiece includes an insert member slidably disposed in the recess and has at least one point substantially complementary to at least one abutment catch for releasable engagement thereagainst. A slide pin is displaceably disposed in the frame and connected to the thumbpiece for joint displacement therewith, yet mounted pivotally relative thereto. The slide pin has a second portion adjacent to the first portion of the hammer, the slide pin being movable between an operative position and an inoperative position. A cylinder disposed in the frame and operatively receiving the slide pin is in an operative position of the latter for retaining the cylinder in the frame, in the inoperative position of the slide pin, the latter being removed from the cylinder, whereby the cylinder is released and spring means operatively bias the thumbpiece and slide pin toward the abutment catch for holding the slide pin and thumbpiece thereagainst.
