This club, which has been refused a patent by the Commissioner of Patents (whose report and our remarks thereon will be found in another part of our columns), is especially intended for the protection of policemen and constables. Fig. 1 represents the ordinary club, 13, with the defensive attachment. It is made hollow, and around its surface are a number of small perforations, through which, when it is grasped by any one trying to wrest it from the policeman, the latter can, by pulling the trigger, A, force out a number of small spikes as seen in Fig. 2. These spikes entering a short distance into the attacker's hand force him to let go his hold, and the policeman loosening the trigger, the spikes fly back. The manner in which this is done is seen in Fig. 3, which is a section of the club. C is a spring against which the trigger has to be pulled, and "by the bars, D, it brings out the spikes; when the hold on the trigger is relaxed, the spring forces them back. There are two eye-holes in the trigger to admit of the strap that passes around the arm. so that if the club is attempted to be violently pulled from the owner, and he lias no chance of operating the trigger, it will "be operated by the strap. It is the invention of John McLarty, of New York, and is exciting a great amount of interest throughout the country generally. It is almost unanimously admitted that these clubs ought to be at once adopted by the police of every city in the world.
